As the world entered the supersonic age, the US Air Force had to assume that the Soviet Union was designing jet bombers. The subsonic interceptors then in service, such as the F-89 Scorpion, would not be adequate. Accordingly, the USAF issued a requirement in 1949 for what was simply called the “1954 Interceptor,” as that was the expected in-service date. Unlike earlier aircraft, however, the new aircraft would be designed around the fire control computer (the Hughes MX-1179) and would incorporate all-missile armament.
Of 18 proposals sent to the USAF, the service chose Convair’s Project MX-1554 in late 1951. This proposal incorporated then radical delta wings, a powerful Wright J67 turbojet, and an internal missile bay that was also equipped with rockets, along with the MX-1179 fire control system. Problems arose with both the engine and fire control system, however, and the USAF decided to go ahead with production of what was now the F-102A Delta Dagger, the third aircraft of the Century Series of fighters in the 1950s. The F-102A was considered as interim until the more advanced F-102B could come online later; emphasis was getting a supersonic interceptor into service as soon as possible, even if it used a less powerful Pratt and Whitney J57 and a simpler M-9 fire control computer. The first YF-102 flew in October 1953.
It was a failure. The YF-102 could not even reach supersonic speeds, its ceiling was below that of even the F-89, and the prototype crashed only a week after its first flight. Convair went back to the drawing board, this time using the recently discovered area rule principle, changing the fuselage from a conventional round shape to a more streamlined “coke bottle,” lengthening and narrowing the nose, and adding shock blisters around the engine. The redesigned YF-102A flew in December 1954, and was able to meet the USAF’s requirements, though it was still slower and had a lower ceiling than the USAF would have liked. Since the F-102A was again only supposed to serve as an interim for the F-102B, which would later become the F-106 Delta Dart, the USAF was willing to overlook the shortfall in performance. The first F-102 entered service in 1956.
In service, the “Deuce,” as it became known, got mixed reviews. The fire control system was improved with an infrared turret forward of the cockpit, and it had comparatively heavy armament in the form of four AIM-4 Falcons and 24 rockets carried in the weapons bay doors. The aircraft were also re-winged with a more efficient design in 1957. Later F-102s had the rockets removed to allow carriage of two AIM-24 Nuclear Falcons.
All this aside, the delta winged design proved to be tricky to get used to, and the F-102 suffered a high accident rate. TF-102A conversion aircraft were built, which involved a radical redesign of the Delta Dagger from the intakes forward, as the TF-102 had side-by-side seating. This adversely affected performance, giving the TF-102 its moniker of “Pig.” Nonetheless, the F-102 was to perform yeoman service throughout the late 1950s and 1960s as an interceptor, supplementing the earlier F-101 Voodoo and its replacement, the F-106. As the Delta Dart entered service, more and more F-102s were relegated to Air National Guard units, where the Deuce would serve until 1976.
F-102s would see wartime service as well. As North Vietnam had a number of Ilyushin Il-28 Beagles in service, F-102s were deployed in detachments to USAF bases in South Vietnam to guard against a surprise attack. These aircraft were drawn from both active duty units and Air National Guard units under Operation Constant Guard. As the Il-28 threat never materialized, the F-102s were used as escorts for USAF missions in Laos or EB-66 jammer aircraft supporting Rolling Thunder sorties. In this capacity, the F-102 would see at least one air-to-air combat with MiG-21s, but came off second best with the loss of aircraft and pilot. Other F-102s were used as ground support aircraft, a role to which the Deuce was completely unsuited, for a brief time and with poor results—though the F-102’s infrared sensors gave it all-weather capability that at that time was matched only by the F-4D Phantom II.
Truly lacking a role, the F-102 detachments were withdrawn from Southeast Asia in 1968. F-102s were exported to Turkey and Greece in the mid-1960s, and these were used in the 1974 Cyprus Crisis; none were reported lost on either side, though rumors persist of Turkish F-102s either shooting down or being shot down by Greek F-5A Freedom Fighters.
All F-102s, foreign and domestic, were withdrawn from service by 1979. In the US, nearly all were converted to QF-102 drones and expended as targets, ending in 1986. Of approximately 900 Delta Daggers produced, at least 35 remain today in museums.
56-2353 is a TF-102, the conversion trainer version of the F-102, known to its pilots as the "Pig." This was a commentary on its flying characteristics, which left a lot to be desired. When feeling charitable, crews called it the "Tub." The nose was redesigned to accomodate two crew sitting side-by-side, rather than the more conventional setup of two-seat aircraft. The F-102 had its own grace, but the TF-102's bizarre appearance tended to ruin it.
56-2353 had an eventful career. It joined the 456th Fighter-Interceptor Squadron at Oxnard AFB, California as its first career assignment, and would knock around no less than nine active-duty and National Guard units (including my hometown unit, the 120th FIG of the Montana ANG) before ending its career with the 176th FIS (Wisconsin ANG) at Truax Field in 1974. The 176th saved the aircraft for preservation, one of eleven TF-102s known to survive.
56-2353 is presented in an attractive flying configuration, and has gotten some paintwork done fairly recently, given the pristine tail colors. The 176th used red tails for both appearance and visibility, as the ADC Gray colors would tend to blend in with a snowy background. The 176th carried the red over to the wing fences as well. As mentioned with the other Volk Field Deuce in my album, the "Wisconsin" legend on the tail is inaccurate: it's in the font of the modern University of Wisconsin Badgers rather than the accurate block letters. However, the Badger font looks better!
New York Army National Guard Soldiers deploy the Tiger Dam flood control system along the shores of Braddock Bay in the Town of Greece, N.Y. in response to rising waters on Lake Ontario. The system consists of flexible fabric tubes which are connected and filled with water. The tubes replace sandbags as a flood control mechanism. Since being ordered to assist in flood mitigation duties by Gov. Andrew M. Cuomo on May 3, New York Army and Air National Guard members, along with members of the New York Naval Militia, have filled more than 673,500 sand bags. ( U.S. Army National Guard photo by Sgt.

Six advisory signs will operate through a central control system to provide real-time train crossing information — indicating if the crossing is open or closed — so drivers can make informed decisions for travel in Langley, Surrey and the Township of Langley. The signs will specify the train’s location and travel direction, enabling drivers to use alternate crossing options at adjacent railway overpasses, in order to avoid traffic delays. In addition to reducing traffic congestion and minimizing greenhouse gas emissions due to decreased vehicle idling times, the signs will increase travel efficiency and mobility for emergency vehicles.
Object Details: Took a few minutes this morning to process our first Jupiter images of the year into a quick animation (please excuse the terrible 'quick & dirty' processing). Therefore, please find attached a short mp4 file showing it's rotation over an actual elapsed time of approx. 90 minutes.
The Great Red Spot (GRS) is visible in the first two frames, rotating off the upper left limb. Although terribly placed at the time, the images do show where the material, which is currently being flaked off the GRS as it unravels, is accumulating (i.e. the 'darker colored area' to the immediate right of the red spot itself - the two features being separated by the more whitish GRS hollow). This material is then being fed is fed into the dark brownish South Equatorial Belt.
The images also highlight the numerous festoons & swirls in the more prominent and colorful North Equatorial Belt with many others disturbances visible thought the various zones & belts. As a bonus Jupiter's moon Ganymede makes a brief guest appearance at the upper left in a few of the frames, prior to disappearing in the final frame due to it's eclipse by Jupiter's shadow.
Image Details: Taken by Jay Edwards at the HomCav Observatory in the early morning hours of May 25, 2019 with an 8-inch, f/7 Criterion newtonian reflector connected to a 3X Televue barlow and ZWO ASI290MC planetary camera / auto-guider. This scope was tracked using a Losmandy G-11 mount running a Gemin 2 control system.
Five short video clips were taken, each approximately 20 minutes apart. These clips were then stacked & wavelet processed in Registax with final processing in PSP & PIPP and are shown here looped three times in succession. Given the less than desirable transparency & seeing conditions combined with fact that the planet was only approximately 20 degrees above the horizon at the time, I was fairly pleased with the results.
The E-3 "Sentry" is an airborne warning and control system (AWACS) aircraft that provides all-weather surveillance, command, control and communications needed by commanders of U.S. and NATO air defense forces. As proven in Desert Storm, it is the premier air battle command and control aircraft in the world today. The E-3 "Sentry" is a modified Boeing 707/320 commercial airframe with a rotating radar dome. The dome is 30 feet (9.1 meters) in diameter, six feet (1.8 meters) thick, and is held 11 feet (3.3 meters) above the fuselage by two struts. It contains a radar subsystem that permits surveillance fromthe Earth's surface up into the stratosphere, over land or water. The radar has a range of more than 200 miles (320 kilometers) for low-flying targets and farther for aerospace vehicles flying at medium to high altitudes. The radar combined with an identification friend or foe subsystem can look down to detect, identify and track enemy and friendly low-flying aircraft by eliminating ground clutter returns that confuse other radar systems-unedited-Not part of my personal collection

Object Details: On September 21, 2022, the last day of summer in the northern hemisphere, mother nature had a parting gift for those of us who are solar aficionado's as two massive sunspot groups began to rotate onto the Earth facing side.
Shown in the images in the attached composite seething with activity & with cores larger than the entire Earth, AR3105 (right) & AR3107 (left) are accompanied by huge amount of faculae (brighter & hotter regions surrounding the groups themselves).
Having survive a complete rotation around the Sun, AR3105 is actually the return of a previous group (then known as AR3089, as it is traditional to renumber active regions upon their return for a another pass of the Earth facing side of the solar disk). As of today these groups are rotating off the Earth facing side while another larger active region is rotating on.
Should flaring occur and release any Earth directed Coronal Mass Ejections & weather and other conditions are permitting, we may experience a wonderful display of the Northern Lights. However aurora aficionados will be quick to note that even should there not be solar flares & their associated CMEs in the offing, during the first weeks of autumn, cracks form in Earth's magnetic field (known as the "Russell-McPherron effect") and at these times even the slightest solar wind may result in geomagnetic activity - it's aurora season !!! :)
Image Details: The images making up this composite were taken by Jay Edwards on early afternoon of Sept. 21, 2022 through high clouds with average seeing and below average transparency from the RoR observatory I built at my home here in upstate, NY using:
At left: A vintage 1970, 8-inch, f/7 Criterion newtonian reflector with a home-made Baader (visual grade material) off-axis solar filter and an unmodded Canon 700D DSLR at prime focus controlled by APT, meant simply as a reference it is a stack of seventeen frames taken at ISO 100 and with a 1/125 second exposure;
At right and below: The same 8-inch, f/7 Criterion newtonian reflector and a home-made Baader off-axis solar filter but in these cases with a ZWO ASI290MC planetary camera / auto-guider at prime focus and a set of specialized planetary filters. They are stacks of several hundred frames, at various exposures ranging from 1.2 to 24 milli-seconds and gain settings of 110 and 300, selected from short video clips consisting of several thousand.
The DLSR was controlled by AstroPhotographyTool (APT), the ASI290MC by SharpCap Pro and the scope was tracked using a Losmandy G-11 goto mount running a Gemini 2 control system. The images also utilized a set of specialized planetary filters (Infrared, Ultraviolet & Methane) in addition to the over-the-aperture solar filter. As shown here the ASI290MC images are at their original resolution while the DSLR shot has been resized down, and the entire composite is shown at three X HD (i.e. 5760 x 3240) and the bit depth for the DSLR shot has been lowered to 8 bits per channel.

Culture passage Karlsplatz opened
The culture passage Karlsplatz was opened on 17 September 2013. It is now modern, bright, clean and safe.
In redesigning the accessibility has been considered. Two elevators and the tactile control system make the passage accessible. Passersby go without stairs to the surface.
Historic Passage fit for the future
On 25 February 1978 the U1 between Karlsplatz and Reumannplatz was Vienna's first underground section and thus the Karlsplatz subway in operation. Some 35 years after its opening, floors, walls and ceilings now have been renovated and equipped with the technical equipment such as fire protection equipment in the passage and in the shops on the cutting edge of technology . Also, the monitoring station and other operating and lounges around the Viennese lines were renewed under the revitalization. A total of approximately 5,000 square stone tiles have been laid, built around 1,800 square meters of glass and installed approximately 1,950 new lights.
A work of art that combines
The 70 -meter-long artwork of internationally renowned Tyrolean artist Ernst Caramelle in the passage direction Resselpark is the main highlight of the new culture passage . The installation makes the room appear in a new perspective . It extends the Karlsplatz existing works of art as the tube installation by Peter Kogler or the art project " Pi " by Ken Lum .
Charm of the 1950s characterizes Opernpassage
The range of Opernpassage is dedicated to the restoration of the original appearance of the 1950s . The flooring in a checkerboard pattern and the use of glass for wall cladding bring back the charm of that era . The work was carried out in close cooperation with the Federal Monuments Office .

Object Details: The Beehive Cluster (Messier 44, NGC 2632, Praesepe, et. al.) is an open cluster which lies a 'mere' 577 light-years from Earth. Although by everyday standards this is still an enormous distance, M44 is one of the closet open clusters to us.
Containing about 550 solar masses whose stars are estimated to be 'only' 650 million years old (as compared to our Sun's 5 billion year age), the cluster's core spans about 23 light-years in diameter.
Visible to the unaided eye as a faint patch of light in the constellation of Cancer, it's constituent stars appear dazzling in nearly any size optical instrument.
Image Details: Taken by Jay Edwards on the March 12, 2019 at the HomCav Observatory using twin Canon 700D (t5i) DSLR connected to (1eft) an Orion 80mm, f/6 triplet carbon-fiber tube apochromatic refractor (ED80T CF) and a 0.8X televue field-flattener / focal reducer; and (right) a vintage (1970) 8-inch, f/7 Criterion newtonian reflector.
With the 80mm piggybacked on the 8-inch, these were tracked using a Losmandy G-11 mount running a Gemini 2 control system. This in turn was guided using PHD2 to control a ZWO ASI290MC planetary camera / auto-guider in an 80mm f/6 Celestron 'short-tube' refractor.
The images are relatively short stacks of subs shot at ISO 400 & 1600 respectively, and as presented here the entire composite has been re-sized down to HD resolution and the bit depth has been lowered to 8 bits per channel.
14.septembrī Starptautiskajā lidostā “Rīga” nosēdās NATO agrīnās brīdināšanas un kontroles sistēmas (Airborne Warning & Control System) lidmašīna, kas ieradusies no Gaisa spēku bāzes Geilenkirhenē, Vācijā.
Latvijā ieradās Sabiedroto spēku augstākās virspavēlniecības Eiropā komandiera vietnieks ģenerālis sers Džeimss Everards (James Everard) un NATO agrīnās brīdināšanas un kontroles spēku komandiere ģenerālmajore Davna Danlopa (Dawn M. Dunlop), pirms tam veicot novērošanas un gaisa telpas kontroles lidojumu no Gaisa spēku bāzes Gailenkirhenē līdz Rīgai.
AWACS ir vienīgie NATO īpašumā esošie gaisakuģi. NATO neizmanto kopējo finansējumu, lai pirktu militāro spēju platformas, proti, kuģus un tankus, jo tā ir katras dalībvalsts individuāla izvēle un atbildība.
Geilenkirhene ir galvenā bāzes vieta Eiropā AWACS lidojumiem, jo no 19 lidmašīnām, kas Eiropā veic lidojumus, 16 bāzējas tieši Geilenkirhenē, vēl trīs atrodas Vašingtonā Lielbritānijā.
Kopš Krimas aneksijas 2014. gadā tiek novērota arī Latvijas gaisa telpa. Reaģējot uz situāciju Ukrainā, NATO Ziemeļatlantijas padome 2014. gada 10. martā ieviesa atbalsta pasākumu plānu, tādējādi demonstrējot alianses vienotību un apņēmību aizsargāt sabiedrotos. Trīs dienas vēlāk, 13. martā, NATO atbalsta pasākumu programmas ietvaros notika pirmais NATO agrīnās brīdināšanas un kontroles sistēmas lidojums no NATO bāzes Geilenkirhenē, Vācijā.
Latvijā AWACS lidmašīna viesojusies divas reizes — 2004. gadā, pirms Latvijas iestāšanās NATO. Savukārt 2016. gada 11. oktobrī, pirmo reizi kopš iestāšanās NATO, Starptautiskajā lidostā “Rīga” piezemējās AWACS lidmašīna, tādējādi demonstrējot pasaulei NATO klātbūtni un lojalitāti Latvijai, Lietuvai, Igaunijai, Polijai un Rumānijai.
AWACS lidmašīnas kopš 2014. gada pavasara ir veikušas vairāk nekā 1000 novērošanas un gaisa telpas kontroles lidojumus.
Par AWACS
“E-3A Sentry” uzbūvēta uz «Boeing 707» bāzes. Lidmašīnas astes galā atrodas radars (tā diametrs 9 m), kas apgādā apkalpi ar datiem, ko analizē datori un citas elektroniskās iekārtas lidmašīnā.
Parasti lidmašīnas lido astoņas stundas aptuveni 10 km augstumā, nosedzot vairāk nekā 400 km novērojamās platības.
Maksimālais ātrums — 853 km/h. Degvielas ietilpība — 89 610 litri. Spēja lidot bez papildu uzpildes — 11 h. Šī modeļa lidmašīnām iespējama uzpilde gaisā, ko veic ar gaisa tankkuģa KC-135 palīdzību. Arī šī lidmašīna izvietota Geilenkirhenē, nodrošinot ilgstošu AWACS uzdevumu izpildi.
Ekipāža — 2 piloti, 1 lidojuma inženieris, 1 navigators, 12 apkalpes locekļi, no kuriem vairāki atrodas taktiskajā operāciju centrā. Modernizētajā AWACS versijā pilotu kabīnē paredzētas 3 vietas, jo tehnoloģiskās inovācijas aizstāj navigatoru.
Gaisakuģa garums — 46,61 m, augstums — 12,73 m, tukšas lidmašīnas masa — 78 000 kg, ekipētas — 147 420 kg.
AWACS nodrošina plaša spektra uzdevumu izpildi, piemēram, gaisa kontroli, pretterorisma akciju atbalstu, evakuācijas, agrās brīdi¬nāšanas un krīzes reaģēšanas operācijas.
AWACS bija svarīga loma NATO operācijās ASV pēc 2001. gada 11. septembra terorakta, pēc viesuļvētras “Katrina” 2005. gadā. Arī 2010. gada zemestrīces Haiti un plūdu seku novēršanā Pakistānā 2010. gadā. AWACS sniedz gaisa atbalstu, lai padarītu drošākus NATO samitus un svarīgus starptautiskus pasākumus, piemēram, ASV prezidenta vizīti 2016. gadā Vācijā, arī Eiropas futbola čempionātu 2016. gadā Francijā.

Update: July 10, 2021 - With several days of intense thunderstorms here this past week, one of which caused a 36 hour blackout at my home, I used some of the time to drain my laptop's battery to process a quick image of the globular cluster M56 which I shot on the evening of July 4th hours after the solar images attached here. Therefore, please find attached below a link to the results of that data. With power now restored, I hope to be able to open my observatory again and continue imaging as soon as the weather allows.

Object Details: On Sunday July 4th I was fortunate to catch the massive sunspot AR 2835 as it was beginning to rotate off the Sun's visible surface. I was also able to image this group on July 2nd but have yet to examine that data - a screenshot of which is attached here:
www.flickr.com/photos/homcavobservatory/51285875171/
One of the reasons I processed the attached 'out of chronologic order' was that, as luck would have it, at the time of the attached it's gigantic dark core (umbra) was splitting into two. The attached composite shows how it appeared in various wavelengths using both short and longer lengths scopes.
When processing the images the 'light-bridge' bisecting the core is readily apparent and due to it's relative brightness was the first thing I happen to notice when examining the infrared shot. The ultraviolet image displays the large amount of plage & faculae in the surround area quite well (i.e. the brighter, hotter regions associated with the active region). As can be seen in the attached, this active area is much larger than the Earth, and it will be interesting to see if it can survive a complete solar rotation.
Image Details: The attached was taken by Jay Edwards at the HomCav Observatory at my home here in upstate, NY on May 19, 2021. The top images were taken with a lum filter, while those at the bottom used infrared (IR), ultraviolet (UV) and methane (CH4) filters (all in addition to an over-the-aperture' off-axis home-made Baader material white light solar filter).
The full disk image, utilizing a Canon 700D controlled by APT & a full aperture Kendricks light light filter on an ED80T CF (i.e. an Orion 80mm, f/6 carbon-fiber triplet apochromatic refractor), and a 0.8X Televue field flattener / focal reducer, is meant merely as a reference for location and it is a single frame shot at 1/4000 and ISO 100. For additional reference a sample image of the Earth was added to show size comparison to the 8-inch shots.
The 'closeup' 8-inch shots were taken using an ASI290MC 'planetary camera / auto-guider' controlled by SharpCap Pro on a vintage 1970, 8-inch, f/7 Criterion newtonian reflector with the above mentioned homemade, off-axis Baader white-light solar filter. Shot as video clips, each is a stack of best several hundred frames out of a total of tens of thousands of frames recorded that afternoon.
Both of these scopes are mounted on and tracked by a Losmandy G-11 running a Gemini 2 control system and the images were processed using a combination of AS3, Registax & PSP. The UV, IR & CH4 images have also been duplicated and having then had their luminance channels extracted, are placed next to their corresponding 'one-shot-color' images.
Processed in a combination of Astrostakkert, Registax & PaintShopPro, as presented here the composite has been resized down to 2X HD resolution and the bit depth lowered to 8 bits per channel.
Object Details: The attached composite shows images of the large sunspot AR2978 in various wavelengths and has been annotated with a sample NASA shot of the Earth for size comparison.
Consisting of a huge core larger than our entire planet, in spite of it's immense size, it's been fairly quiet; however it's size did enable the prediction of it's arrival on the southeastern limb back on March 25th as seen by Nasa's helioseismic far-side imaging.
Indications of a short 'light-bridge' like structure can be seen at the top of the spot, and like the faculae, tends to be more readily visible in the UV image. Although AR2978 has rotated off the visible surface today, helioseismic far-side imaging is once again indicating the presence of a huge back-side active region. In this case the current theory is that it may be the previous sunspot AR2975.
If this is indeed the case, assuming it survives a complete rotation around the solar disk we may be in for a treat since, as mentioned in the text accompanying the link below,
'... AR2975 released several solar flares this week as it traversed the disk; including an M9.4 and a X1.3 class. These resulted in 'cannibalistic' coronal mass ejections (CMEs) and a geomagnetic storm with aurora visible in the northern tier states of the US ...'
I was fortunate to catch AR2975 just prior to it rotating off the limb on April 4th as shown here:

Image Details: Taken by Jay Edwards on the afternoon of April 5, 2022 from the RoR observatory I built at my home here in upstate, NY using -
at upper left: An Orion ED80T CF (i.e. an 80MM, f/6 triplet, carbon-fiber refractor) with a 0.8x Televue field flattener / focal reducer, Kendrick film solar filter and an unmodded Canon 700D DSLR controlled by APT, it is a stack of 32 frames taken at ISO 100 and with a 1/4000 second exposure;
at top center: A Celestron 'short-tube' 80MM, f/5 refractor with a Thousand-Oaks glass solar filter and an ASI290MC planetary camera / auto-guider controlled by SharpCap Pro, this is a stack of several hundred frames selected from several thousands shot at 0.768 milliseconds, and
At upper right & below, a vintage 1970, 8-inch, f/7 Criterion newtonian reflector with a home-made Baader (visual grade material) off-axis solar filter and the aforementioned ASI290MC. As with the 80MM Celestron shot, they are stacks of several hundred frames, in this case at various exposures, selected from short video clips consisting of several thousand.
In both cases the ASI290MC was placed at prime focus and was controlled by SharpCap Pro and all scopes were tracked using a Losmandy G-11 goto mount running a Gemini 2 control system. The images at bottom also utilized a set of specialized planetary filters (Infrared, Ultraviolet & Methane) in addition to the over-the-aperture solar filter. As shown here the entire composite has been resized down to HD (one-third of it's original resolution).
Hoping the next week or so brings AR2975 back into view and brings with it some wonderful auroral activity - stay tuned !

NATO Air Base Geilenkirchen, (IATA: GKE, ICAO: ETNG) located near Geilenkirchen, Germany, is the main operating airfield of the NATO Airborne Early Warning & Control Force (NAEW&CF) Command's E-3A Component (AWACS). This component provides an early warning radar system to enhance NATO's air defence capabilities. Seventeen E-3A aircraft are used for air surveillance and air operations communications support. Aircraft are flown by multinational crews from 14 nations including Poland, Belgium, Canada, Denmark, Germany, Greece, Hungary, Italy, the Netherlands, Norway, Portugal, Spain, Turkey, and the United States.
The NATO Airborne Early Warning Force was created in January 1982 and is NATO's only multinational operational flying unit. The Geilenkirchen base was originally known as RAF Geilenkirchen, a Royal Air Force (RAF) station built after World War II.
Though the E-3 Sentries and Boeing 707s operate from mainly from the Geilenkirchen air base, they also operate from Preveza-Aktion (Greece) and Ørland Main Air Station (Norway).
An Airborne Early Warning and Control (AEW&C) system is an airborne radar system designed to detect aircraft. Used at a high altitude, the radars allow the operators to distinguish between friendly and hostile aircraft hundreds of miles away. AEW&C aircraft are used for defensive and offensive air operations. The system is used offensively to direct fighters to their target locations, and defensively to counter attacks. It can also be used to carry out surveillance, and C2BM (command and control, battle management) functions.
AEW&C is also known the older terms "Airborne Early Warning" (AEW) and "Airborne Warning and Control System" (AWACS).
Modern AWAC systems can detect aircraft from up to 400 km (250 miles) away, well out of range of most surface-to-air missiles. One AWACS plane flying at 9150 meters (30000 feet) can cover an area of 312000 square kilometers. Three of such aircrafts in overlapping orbits can cover the whole Central Europe.[1] In air-to-air combat, AWAC systems can communicate with friendly aircraft, extend their sensor range and give them added stealth, since they no longer need their own active radar to detect threats. However, by the nature of radar, AWACS aircraft can be detected by opposing forces beyond its own detection range. This is because the outgoing pulse reduces in strength the further it travels. Therefore, a signal which is intended to go out and be reflected back must be strong enough to cover twice the distance between the sender and the target.

Day 5 of the Hurricane Sandy Aerial Photography Tour: Great Dismal Swamp, VA.
The U.S. Navy had begun planning a replacement for the F-4 Phantom II in the fleet air defense role almost as soon as the latter had entered service. However, it was ordered by the then-Secretary of Defense Robert McNamara to join the TFX program. The subsequent F-111B failed in nearly every way except for its AWG-9 fire control system, paired with the AIM-54 Phoenix long-range air-to-air missile. It was canceled soon after, and the competition was reopened for a new fighter, but Grumman had anticipated the cancellation and responded with a more unique design.
The subsequent F-14A Tomcat was the last entry in the famous 'Grumman Cat' series of U.S. Naval fighters. It first flew in December of 1970 and was placed into production soon after. It used the same variable-sweep wing concept of the F-111Bs and its AWG-9 system, but the Tomcats had a much sleeker appearance and were lighter. The F-14s had a diverse arsenal of weapons, including the Phoenix, long-range AIM-7 Sparrow, short-range AIM-9 Sidewinder, and an internal M61A1 Vulcan 20mm Gatling cannon. This directly responded to the lessons learned in Vietnam, where the Navy's F-4 Phantoms desperately needed internal armaments. Despite its larger size, the F-14 proved an excellent dogfighter, a testament to its unique design and capabilities.
The only real drawback to the design was the engines, which it shared with the F-111B: the Pratt and Whitney TF30. The TF30 was found to be prone to compressor stalls and even explosions; more F-14s would be lost to engine problems than any other cause during its career, including combat. The Tomcat was also fitted with the TARPS camera pod beginning in 1981, allowing the RA-5C Vigilante and RF-8G Crusader dedicated recon aircraft to be retired. In addition to the aircraft produced for the U.S. Navy, attempts were made to sell the plane to the air forces of Canada, Germany, and Japan; however, the Imperial Iranian Air Force (IIAF) would be the only foreign customer for the aircraft with 79 out of an order of 100 aircraft being delivered to Iran before the Islamic Revolution of 1979.
The F-14 Tomcat, after entering service in 1974, quickly proved its worth in combat. Its first significant action was in the 1980-1988 Iran-Iraq War, where Iranian F-14s, including the only F-14 ace, Jalil Zandi, achieved several kills. The first American combat with the F-14s came in 1981 when two F-14As shot down a pair of Libyan Su-22 Fitters over the Gulf of Sidra. The Tomcat would add two more kills to its record in 1987, two Libyan MiG-23s again over the Gulf of Sidra. These early successes set the stage for the F-14's impressive combat history.
The high losses due to problems with the TF30s (Up to 84 Tomcats would be lost to this problem throughout its career) led to the Navy ordering the F-14A+ variant during the war. The A+ was redesigned as the F-14B in 1991, incorporating all wartime refits and, most importantly, new General Electric F110 turbofans. Among the refits was the replacement of the early A's simple under-nose IR sensor with a TISEO long-range camera system, allowing the F-14's pilot to identify targets visually beyond the range of unaided human eyesight. These improvements significantly enhanced the F-14's combat capabilities.
Most of the F-14As were upgraded to B standards, along with 67 newly-built aircraft. A mix of F-14As and Bs would see action in the First Gulf War, though only a single kill was scored by Tomcats. After this conflict, the Navy ordered the F-14D "Super Tomcat" variant, with completely upgraded avionics and electronics, a combination IRST/TISEO sensor, replacement of the AWG-9 with the APG-71 radar, and a "glass" cockpit. Though the Navy had intended to upgrade the entire fleet to D standards, less than 50 F-14Ds ever entered service (including 37 new-builds) due to the increasing age of the design.
Ironically, the U.S. Navy's Tomcat finale came not as a fighter but as a bomber. To cover the retirements of the A-6 Intruder and A-7 Corsair II from the fleet, the F-14's latent bomb capabilities were finally utilized, allowing the 'Bombcat' to carry precision-guided weapons, and, after 2001, the GPS-guided JDAM series. By the time of the Afghanistan and Second Gulf Wars, the F-14 was already slated for replacement by the F/A-18E/F Super Hornet, and the Tomcat would be used mainly in the strike role, though TARPS reconnaissance sorties were also flown. The beloved F-14 Tomcats were finally retired from U.S. Navy service in September 2006, ending 36 years of operations. Today, there are over 80 Tomcats on display across the U.S. while most were scrapped. The aircraft remains in service with the Iranian Revolutionary Air Force.
This F-14A, BuNo 160684, was built in December of 1978 and delivered to Fighter Squadron 111, the famous "Sundowners," aboard USS Kitty Hawk (CV-63) in 1979. It would serve a good portion of its career aboard the Kitty Hawk with a notable action in this aircraft's career occurring in October 1985. This aircraft intercepted an EgyptAir Boeing 737 carrying the four Italian cruise ship Achilles Lauro hijackers. Under direct orders from President Reagan, the F-14 intercepted the plane 80 miles south of Crete. It flew wing to wing with the 737, forcing it to land safely at a NATO air base in Sicily. 160684 finished its career with VF-124 ("Gunfighters"), which served as the Fleet Replacement Squadron for F-14 units then operating in the Pacific Fleet, as well as aircraft for students in the Top Gun program. When VF-124 was disestablished in 1994 with the gradual post-Cold War drawdown of all Tomcat squadrons, 160684 was also retired. In 1994, she was spared from the scrapper's torch and donated to the Pima Air and Space Museum.
In this author's opinion, VF-111 was the ultimatum in Tomcat markings. Besides putting tail codes, numbers, and carrier names in bright red, VF-111 was the only F-14 squadron to paint their aircraft with shark mouths. The squadron's "Sundowner" emblem was carried on the ventral fin on some aircraft, including this one; on some squadron's aircraft, it took up the entire tail. The name and emblem refer to the squadron's impressive record against the Japanese in World War II. F-14 units carried the overall light gray camouflage in the 1980s, though they were usually not this glossy.
If there is someone who grew up in the 80s who was not a fan of "Top Gun," I have yet to meet them; it was awesome to see an F-14 in such a fantastic condition! In my opinion, the Tomcat is one of the sexiest American fighter jet designs of all time!

The labor-intensive job of diverting fresh water into the Savannah National Wildlife Refuge has become easier since the U.S. Army Corps of Engineers Savannah District replaced the old wooden structures with custom-built diversion gates. The Fresh Water Control System was originally installed as a mitigation feature for the 1977 Savannah harbor deepening project. At a cost of $12.5 million, the new stainless steel structures modernize and automate the process of controlling water in the area. Previously, wildlife managers with the U.S. Fish and Wildlife Service could only route water to 3,000 acres of wetlands for waterfowl; with the gate improvements, the water management area has doubled to 6,000 acres. The project was completed in autumn 2011.

Marquardt Corporation promotional? photograph of a scale model Lunar (Excursion) Module LEM/LM. Note the translucent appearance of the Reaction Control System (RCS) thrusters/nozzles. In all other similar models of the LEM/LM, they’re always opaque, solid and/or metallic.
Marquardt was responsible for the LEM/LM RCS engines.
Note also what appears to be wiring…possibly leading up into the descent stage engine bell. That, along with the appearance/material used for the RCS thrusters maybe suggests that they “light up” … for promotional purposes? ¯\_(ツ)_/¯
Finally, and to me, amusingly, it seems to be loosely emulating the Craig Kavafes depiction of good ol' no. 10, and linked to below.

...15 years younger. I haven't been on a plane yet. I was in college; I was dealing with Integrals, and control systems, and Fourier calculations, and a few classmates who's only forte was bragging -- and technical drawing, after the drawing classes were gone all they can do was look "cool"(aside from consistently dealing with failing grades) at least -- for the most of them; I only have 1% of the enemies that I have now, but I have more friends now though; No one has betrayed me yet; I have owned a film camera for three years when I last walked in this city; Dolphins greeted the boat as it approaches the city's port; There was less traffic; Some of my relatives told me the school in front of this obelisk is good, and it was even considered that maybe I can study here someday, but it was not to be; The only mall in this place was called Lim Ket Kai; I had a simpler life back then; The only money I earn is the bits of my daily allowance -- and the tuition fee refund I got from school; I was thinner, more physically fit, and maybe more deadly, and can outrun, out swim, outplay and out jump almost anyone I knew.
When I departed this city the last time, my relatives told me "balik balik unya pohon...", a Philippine dialect term for something like "come back here soon"... and now I realized, that "soon" was to be 15 years later. Times have changed now... and all those memories still percolating in my mind -- that was 15 years ago when time seemed to have been crawling all along. And the funny part of it is... all of my companions on this trip now were still in high school(probably elementary) during the time when I last came here.

NASA's Human Robotic Systems Project, part of the agency's Exploration Technology Development Program, focused on human and robotic mobility systems for the moon, but also looked at communication and command and control systems that will connect the explorers with Earth and each other. The Moses Lake dunes provided a wide variety of soil consistencies and terrain that allowed the team to put prototype scout robots, rovers, cargo carriers, cranes and spacesuits through tests in a harsh and changing environment.
The prototype tests will be used to inform developers of specific requirements needed in lunar surface support systems for the Constellation Program. The program is building the launch vehicles and spacecraft that will take a new generation of explorers to the moon, as well as lunar landers, habitats, life support systems, vehicles and robots to support them. A ground control team located thousands of miles away at Johnson operated the robots and coordinated the movements of the suited explorers.
NASA's Ames Research Center in Moffett Field, Calif., tested two K10 rovers that surveyed simulated lunar landing sites and built topographic and panoramic 3-D terrain models. One rover used a ground-penetrating radar to assess subsurface structures. The other used a 3-D scanning laser system known as LIDAR to create topographic maps. The scout robots are designed to perform highly repetitive and long-duration tasks, such as site mapping and science reconnaissance.JPL tested two ATHLETE cargo-moving rovers. Each rover has six legs capable of rolling or walking over extremely rough or steep terrain. This will allow robotic or human missions on the surface of the moon to load, manipulate, deposit and transport payloads to desired sites. The team includes members from Johnson, Ames, Stanford University and The Boeing Co. of Chicago.
NASA's Glenn Research Center in Cleveland, and Carnegie Mellon University of Pittsburgh tested an autonomous drilling rover that could be used to search for valuable resources under the lunar surface in the moon's polar regions. The team also includes members from Ames, Johnson, NASA's Kennedy Space Center, the Canadian Space Agency and the Centre for Advanced Technology Inc. in Sudbury, Ontario.
The building is the seat of the state parliament of North Rhine-Westphalia.
During the modernisation of the assembly hall, Colt installed 700 large Solarfin shading louvres to optimise the flow of light and heat energy into the building, offering a substantial saving with regards to energy costs on cooling during the summer months. The louvres are designed to follow the path of the sun, and are moved by a PIA control system.
The Interstate 80 eastbound Cordelia weigh station features Intelligent Imaging Systems' Smart Roadside Inspection System platform, which includes the deployment of advanced vehicle identification, screening and sorting capabilities. Smart Roadside includes the installation of a host of innovative roadside sensors integrated into a weigh station management and traffic control system. The roadside sensors will allow the system to automatically screen moving vehicles based on weight, height and, for the first time in California, the presence of hazardous material placards and safety inspection decals. The Smart Roadside application helps California Highway Patrol (CHP) commercial vehicle inspectors automate the process of choosing high-risk trucks for closer scrutiny from the more than 125,000 trucks that pass through the station every month.

I have found it very difficult to get information on the ZF gearbox and its control system. ZF are not intrested in helping much and specialists are not willing to help unless they are being hired at cost to do the work. None of this was any use to me as I want to learn the systems of the bus and how to repair them myself as for me this is the bit I enjoy the most. After a lot of phoning I finally managed to get sent a wiring diagram for the ZF EST18 system. This allowed me to carefully trace the 12 chopped gear selector wires. Graham had recovered a working gear selector for the plug and he had the sense to locate and save the multiplug. Using the old plug I was able to buy new pins which will allow me to repair the wiring loom on the bus. This will mean the gear selector will simply plug in "IF" I get the wiring correct.
14.septembrī Starptautiskajā lidostā “Rīga” nosēdās NATO agrīnās brīdināšanas un kontroles sistēmas (Airborne Warning & Control System) lidmašīna, kas ieradusies no Gaisa spēku bāzes Geilenkirhenē, Vācijā.
Latvijā ieradās Sabiedroto spēku augstākās virspavēlniecības Eiropā komandiera vietnieks ģenerālis sers Džeimss Everards (James Everard) un NATO agrīnās brīdināšanas un kontroles spēku komandiere ģenerālmajore Davna Danlopa (Dawn M. Dunlop), pirms tam veicot novērošanas un gaisa telpas kontroles lidojumu no Gaisa spēku bāzes Gailenkirhenē līdz Rīgai.
AWACS ir vienīgie NATO īpašumā esošie gaisakuģi. NATO neizmanto kopējo finansējumu, lai pirktu militāro spēju platformas, proti, kuģus un tankus, jo tā ir katras dalībvalsts individuāla izvēle un atbildība.
Geilenkirhene ir galvenā bāzes vieta Eiropā AWACS lidojumiem, jo no 19 lidmašīnām, kas Eiropā veic lidojumus, 16 bāzējas tieši Geilenkirhenē, vēl trīs atrodas Vašingtonā Lielbritānijā.
Kopš Krimas aneksijas 2014. gadā tiek novērota arī Latvijas gaisa telpa. Reaģējot uz situāciju Ukrainā, NATO Ziemeļatlantijas padome 2014. gada 10. martā ieviesa atbalsta pasākumu plānu, tādējādi demonstrējot alianses vienotību un apņēmību aizsargāt sabiedrotos. Trīs dienas vēlāk, 13. martā, NATO atbalsta pasākumu programmas ietvaros notika pirmais NATO agrīnās brīdināšanas un kontroles sistēmas lidojums no NATO bāzes Geilenkirhenē, Vācijā.
Latvijā AWACS lidmašīna viesojusies divas reizes — 2004. gadā, pirms Latvijas iestāšanās NATO. Savukārt 2016. gada 11. oktobrī, pirmo reizi kopš iestāšanās NATO, Starptautiskajā lidostā “Rīga” piezemējās AWACS lidmašīna, tādējādi demonstrējot pasaulei NATO klātbūtni un lojalitāti Latvijai, Lietuvai, Igaunijai, Polijai un Rumānijai.
AWACS lidmašīnas kopš 2014. gada pavasara ir veikušas vairāk nekā 1000 novērošanas un gaisa telpas kontroles lidojumus.
Par AWACS
“E-3A Sentry” uzbūvēta uz «Boeing 707» bāzes. Lidmašīnas astes galā atrodas radars (tā diametrs 9 m), kas apgādā apkalpi ar datiem, ko analizē datori un citas elektroniskās iekārtas lidmašīnā.
Parasti lidmašīnas lido astoņas stundas aptuveni 10 km augstumā, nosedzot vairāk nekā 400 km novērojamās platības.
Maksimālais ātrums — 853 km/h. Degvielas ietilpība — 89 610 litri. Spēja lidot bez papildu uzpildes — 11 h. Šī modeļa lidmašīnām iespējama uzpilde gaisā, ko veic ar gaisa tankkuģa KC-135 palīdzību. Arī šī lidmašīna izvietota Geilenkirhenē, nodrošinot ilgstošu AWACS uzdevumu izpildi.
Ekipāža — 2 piloti, 1 lidojuma inženieris, 1 navigators, 12 apkalpes locekļi, no kuriem vairāki atrodas taktiskajā operāciju centrā. Modernizētajā AWACS versijā pilotu kabīnē paredzētas 3 vietas, jo tehnoloģiskās inovācijas aizstāj navigatoru.
Gaisakuģa garums — 46,61 m, augstums — 12,73 m, tukšas lidmašīnas masa — 78 000 kg, ekipētas — 147 420 kg.
AWACS nodrošina plaša spektra uzdevumu izpildi, piemēram, gaisa kontroli, pretterorisma akciju atbalstu, evakuācijas, agrās brīdi¬nāšanas un krīzes reaģēšanas operācijas.
AWACS bija svarīga loma NATO operācijās ASV pēc 2001. gada 11. septembra terorakta, pēc viesuļvētras “Katrina” 2005. gadā. Arī 2010. gada zemestrīces Haiti un plūdu seku novēršanā Pakistānā 2010. gadā. AWACS sniedz gaisa atbalstu, lai padarītu drošākus NATO samitus un svarīgus starptautiskus pasākumus, piemēram, ASV prezidenta vizīti 2016. gadā Vācijā, arī Eiropas futbola čempionātu 2016. gadā Francijā.

Update Dec. 21, 2021 - A composite showing these, as well as images in other wavelengths, that have been stacked and processed can be found the the link attached here - www.flickr.com/photos/homcavobservatory/51761604013/
With a storm last night which knocked out the power here, and another due to move into our area tonight and bring with it snow & ice; I was lucky to be able to catch the Sun during the short break between the cloud banks this morning.
Solar activity is beginning to increase again with the appearance of Active Regions 2907, 2908 & 2909 over the past few days forming a 'chain-like' line across the visible surface (left to right respectively) for what a quick estimate in comparison to the Sun's overall diameter seems to indicate is over 240,000 miles (nearly 400,000 km) long ! In addition, a new region (AR2911), has become visible on the upper left limb.
The attached composite of single frame images (grabbed from recorded videos) show an overall full disk 'reference image' and 'close-ups' of both the AR 2907-2908-2909 'chain' as well as the newly appearing AR2911.
They were shot thru homemade Baader (visual grade material) white-light solar filters on an 80mm, f/5 refractor and a vintage 1970, 8-inch, f/7 Criterion newtonian reflector. Both used a ZWO ASI290MC planetary camera / autoguider controlled by SharpCap Pro, and the scopes were mounted on & tracked via a Losmandy G-11 running a Gemini 2 control system.
With the seeing varying somewhere between horrible & terrible ;) , and the full disk being a composite of only two single frames (left & right halves) and
the 8-inch shots are individual single frames; they all contain quite a bit of noise. Having taken thousands of such frames today through both luminance filters as shown here, and with the 8-inch employing Ultraviolet, Infrared & Methane filters as well;
I'm looking forward to seeing what details I can pull out of the data once it is stacked & processed.
As is typical for most of my astronomical endeavors, once again today I've been enjoying musical accompaniment - in this case in the form of a wonderful concert by the Allman Brothers from the Fillmore East (shown here doing an excellent rendition of 'Whipping Post'). Having been a fan of their music for decades, I actually have this 'Live At The Fillmore East' double album in my vinyl collection (a digital version of which I am listening to as I type this :) ) . I was fortunate to catch them in concert back in the late 90's at a ski resort in our area where they put on a fabulous show (albeit given the jamming they are noted for, at times it seemed like one single three-hour long song :) ) !
As a side note it was reported that Active Region produced a M1 class solar flare at 0051 UT today. There are now several groups able to produce flares of this magnitude (or possibly higher if we're lucky ? ;) ) that should be moving into geomagnetic effective positions soon. In addition to my ever-present wish for Peace On Earth; it would be nice if Santa could bring us a wonderful auroral display for the holidays ;) - Stay Tuned !!!
Mirage IIIS pride of the Swiss Air Force during the Cold War
1:45 scale to match the train I'm working on with the nickname "Mirage" because of its acceleration due to it's all axle drive. Both the train and the jet entered service during the 1960s.
This model was built using only genuine bricks. Metallic Silver is a fun color to build with.
According to Wikipedia the Swiss version is fitted with an indigenous "Hughes Taran 18 radar and fire-control system, which gave it the ability to fire the AIM-4 Falcon and Sidewinder air-to-air missiles. Built under license in Switzerland." (Wiki).
So the Swiss built a plane that could fire the AIM-4 Falcon before the F-14 Tomcat existed.

The Erieye radar system is an Airborne Early Warning and Control System (AEW&C) developed by Saab Electronic Defence Systems (formerly Ericsson Microwave Systems) of Sweden. It uses active electronically scanned array (AESA) technology. The Erieye is used on a variety of aircraft platforms, such as the Saab 340 and Embraer R-99. It has recently been implemented on the Bombardier Global 6000 aircraft as the Globaleye.
The Erieye Ground Interface Segment (EGIS; not to be confused with the Aegis combat system) is a major component of the software used by the Erieye system.
The radar provides 300 degree coverage and has an instrumental range of 450 km and detection range of 350 km in a dense hostile electronic warfare environment—in heavy radar clutter and at low target altitudes. In addition to this, the radar is also capable of identifying friends or foes, and has a sea surveillance mode.
The Erieye system has full interoperability with NATO air defence command and control systems.
Design
The Erieye AEW&C mission system radar is an active, phased-array, pulse-doppler sensor that can feed an onboard operator architecture or downlink data (via an associated datalink subsystem) to a ground-based air defence network. The system employs a large aperture, dual-sided antenna array housed in a dorsal 'plank' fairing. The antenna is fixed, and the beam is electronically scanned, which provides for improved detection and significantly enhanced tracking performance compared with radar-dome antenna systems. Erieye detects and tracks air and sea targets out to the horizon, and sometimes beyond this due to anomalous propagation — instrumented range has been measured at 450 kilometres (280 mi). Typical detection range against fighter-sized targets is approximately 425 kilometres (264 mi), in a 150° broadside sector, both sides of the aircraft. Outside these sectors, performance is reduced in forward and aft directions.
Other system features include: Adaptive waveform generation (including digital, phase-coded pulse compression); Signal processing and target tracking; track while scan (TWS); low side lobe values (throughout the system's angular coverage); low- and medium-pulse repetition frequency operating modes; frequency agility; Air-to-air and sea surveillance modes; and target radar cross-section display.
The radar operates as a medium- to high-PRF pulse-Doppler, solid-state radar, in E/F-band (3 GHz), incorporating 192 two-way transmit/receive modules that combine to produce a pencil beam, steered as required within the operating 150° sector each side of the aircraft (one side at a time). It is understood that Erieye has some ability to detect aircraft in the 30° sectors fore and aft of the aircraft heading, but has no track capability in this sector.
The Environmental Control System and Cabin Interiors rig (ECS/Interiors), a full-scale test rig to enable development testing of air systems, lighting, cabin management system (CMS), audio system and in-flight entertainment (IFE) on the CSeries aircraft. Located in the Complete Integrated Aircraft Systems Test Area (CIASTA or Aircraft 0) facility in Mirabel Quebec, the ESC includes a representative flight deck in order to allow complete ECS testing.

14.septembrī Starptautiskajā lidostā “Rīga” nosēdās NATO agrīnās brīdināšanas un kontroles sistēmas (Airborne Warning & Control System) lidmašīna, kas ieradusies no Gaisa spēku bāzes Geilenkirhenē, Vācijā.
Latvijā ieradās Sabiedroto spēku augstākās virspavēlniecības Eiropā komandiera vietnieks ģenerālis sers Džeimss Everards (James Everard) un NATO agrīnās brīdināšanas un kontroles spēku komandiere ģenerālmajore Davna Danlopa (Dawn M. Dunlop), pirms tam veicot novērošanas un gaisa telpas kontroles lidojumu no Gaisa spēku bāzes Gailenkirhenē līdz Rīgai.
AWACS ir vienīgie NATO īpašumā esošie gaisakuģi. NATO neizmanto kopējo finansējumu, lai pirktu militāro spēju platformas, proti, kuģus un tankus, jo tā ir katras dalībvalsts individuāla izvēle un atbildība.
Geilenkirhene ir galvenā bāzes vieta Eiropā AWACS lidojumiem, jo no 19 lidmašīnām, kas Eiropā veic lidojumus, 16 bāzējas tieši Geilenkirhenē, vēl trīs atrodas Vašingtonā Lielbritānijā.
Kopš Krimas aneksijas 2014. gadā tiek novērota arī Latvijas gaisa telpa. Reaģējot uz situāciju Ukrainā, NATO Ziemeļatlantijas padome 2014. gada 10. martā ieviesa atbalsta pasākumu plānu, tādējādi demonstrējot alianses vienotību un apņēmību aizsargāt sabiedrotos. Trīs dienas vēlāk, 13. martā, NATO atbalsta pasākumu programmas ietvaros notika pirmais NATO agrīnās brīdināšanas un kontroles sistēmas lidojums no NATO bāzes Geilenkirhenē, Vācijā.
Latvijā AWACS lidmašīna viesojusies divas reizes — 2004. gadā, pirms Latvijas iestāšanās NATO. Savukārt 2016. gada 11. oktobrī, pirmo reizi kopš iestāšanās NATO, Starptautiskajā lidostā “Rīga” piezemējās AWACS lidmašīna, tādējādi demonstrējot pasaulei NATO klātbūtni un lojalitāti Latvijai, Lietuvai, Igaunijai, Polijai un Rumānijai.
AWACS lidmašīnas kopš 2014. gada pavasara ir veikušas vairāk nekā 1000 novērošanas un gaisa telpas kontroles lidojumus.
Par AWACS
“E-3A Sentry” uzbūvēta uz «Boeing 707» bāzes. Lidmašīnas astes galā atrodas radars (tā diametrs 9 m), kas apgādā apkalpi ar datiem, ko analizē datori un citas elektroniskās iekārtas lidmašīnā.
Parasti lidmašīnas lido astoņas stundas aptuveni 10 km augstumā, nosedzot vairāk nekā 400 km novērojamās platības.
Maksimālais ātrums — 853 km/h. Degvielas ietilpība — 89 610 litri. Spēja lidot bez papildu uzpildes — 11 h. Šī modeļa lidmašīnām iespējama uzpilde gaisā, ko veic ar gaisa tankkuģa KC-135 palīdzību. Arī šī lidmašīna izvietota Geilenkirhenē, nodrošinot ilgstošu AWACS uzdevumu izpildi.
Ekipāža — 2 piloti, 1 lidojuma inženieris, 1 navigators, 12 apkalpes locekļi, no kuriem vairāki atrodas taktiskajā operāciju centrā. Modernizētajā AWACS versijā pilotu kabīnē paredzētas 3 vietas, jo tehnoloģiskās inovācijas aizstāj navigatoru.
Gaisakuģa garums — 46,61 m, augstums — 12,73 m, tukšas lidmašīnas masa — 78 000 kg, ekipētas — 147 420 kg.
AWACS nodrošina plaša spektra uzdevumu izpildi, piemēram, gaisa kontroli, pretterorisma akciju atbalstu, evakuācijas, agrās brīdi¬nāšanas un krīzes reaģēšanas operācijas.
AWACS bija svarīga loma NATO operācijās ASV pēc 2001. gada 11. septembra terorakta, pēc viesuļvētras “Katrina” 2005. gadā. Arī 2010. gada zemestrīces Haiti un plūdu seku novēršanā Pakistānā 2010. gadā. AWACS sniedz gaisa atbalstu, lai padarītu drošākus NATO samitus un svarīgus starptautiskus pasākumus, piemēram, ASV prezidenta vizīti 2016. gadā Vācijā, arī Eiropas futbola čempionātu 2016. gadā Francijā.
