NATO aircrew patrol the skies over Poland in their E-3A Airborne Warning and Control System (AWACS) aircraft.
NATO’s Airborne Warning and Control System (AWACS) aircraft have deployed to Lithuania to monitor the skies over eastern Europe. NATO has increased its air presence in the eastern part of the Alliance using fighter jets, surveillance planes and tankers. The NATO AWACS mission is scheduled to last several weeks. Around 150 military personnel from Czechia, Denmark, Germany, the Netherlands, Türkiye, and the United States, have deployed to Šiauliai in support of the aircraft.
As coastal artillery guns became larger, and their range increased, growing demands were placed on the fire control systems that targeted potential naval targets. By World War II the 16” guns of Battery Townsley and Battery Davis could fire a projectile 25 miles to sea. And there is a lot of sea out there at that range. To be effective the projectile would have to strike its target and that is where the artillery fire control system came into play.
Fire control systems basically sighted targets from multiple vantage points along the shore. The vantage points were connected by baselines of known relationship. The sighting direction from each fire control station was transmitted to a central fire control plotting room where the readings were fed into an analog computer, essentially adjustable arms on a large plotting table (see video). The coordinates of a target ship were updated at 20 second intervals to establish a ship trajectory, A projectile fired by the 16” guns was in the air for about 90 seconds so several intervals of plotting would occur while the load was in flight.
Coastal batteries with smaller weapons could use fire control stations that were relatively close to each other. However, the range of the 16” guns required fire control stations that were quite far apart. In the Bay Area these began down past Pacifica to the south and ranged all the way up to Wildcat in Pt. Reyes. The Hill 640 Military Reservation, located on coastal bluffs just south of Stinson Beach near the intersection of Panoramic Highway and Highway 1, had five fire control stations with each station associated with a different 16” gun installation. The site has fire control stations for completed batteries (Townsley and Davis) and unfinished batteries (129 and 243) plus a fifth fire control station of unknown association. It is interesting that while the fire control stations all belonged to the same era they have different designs. There must be a story behind this circumstance. It is also interesting that targeting information was not shared between the batteries.
Our visit found the fire control stations all grouped together above Highway 1. They seem to be in pretty good shape for structures built 70 years ago.

Pogo-Hi was a rocket-propelled target missile designed primarily for testing the guidance and control systems of missiles. It was an upgraded version of the Pogo target. The chief external difference between the two was the fins: Pogo had triangular fins, while Pogo-Hi had ------ [?]
Pogo-Hi was equipped with a metalized reflective parachute which presented a simulated aircraft target to radar. Reaching altitudes from 30,000 feet to 175,000 feet, it was fired from mobile launchers which allowed it to be supplied at any distance from the radar.
Physical Science Laboratory of New Mexico College of Agriculture and Mechanical Arts (now NMSU) developed Pogo-Hi under contract with the Navy Bureau of Ordnance
The U.S. Navy used Pogo-Hi for tests of the Sidewinder infrared guided missile by fitting the payload under the parachute with a bright infrared source. The Army also utilized Pogo-Hi.
At White Sands Missile Range, Pogo-Hi was first fired in April 1954 and the last one was launched by the Army in 1960.

old railroad signal control system known as a Centralized Traffic Control (CTC) board. The equipment was donated by the SouhthernPacific Transportation Co. A plaque says this console controlled the "Gila Line" between Yuma's "East Yard" and the "Stockham" yard in Tucson (Prince Road at I-10 crossing).
The CL Series Valiant was introduced in November 1976. Although it used the same bodyshell as the previous VK range, the front and rear ends were restyled. The front end used horizontally arrayed quad round headlamps flanking a central grille. The front guards and bonnet were also reworked accordingly. The new bootlid's curved leading edge flowed down to new taillights that sandwiched a simple centre garnish panel. The bumpers, however, were the same units as had been used on the 1969 VF series Valiants.
The 3.5 L (215 cu in) Hemi-6 and 5.9 L (360 cu in) V8 were dropped, and the only engine options were low- and high-compression versions of the 4.0 L (245 cu in) Hemi-6 and the 5.2 L (318 cu in) V8. The CL's introduction had closely coincided with that of the strict exhaust emission regulations contained in ADR 27A. With the 318 engine, a new emissions control system was introduced: Electronic Lean Burn.
Valiant and Regal sedans also benefited from the 1978 introduction of Radial Tuned Suspension in response to Holden's having marketed their suspension as particularly suited to radial tyres.
36,672 CL Valiants — including the last-ever Chargers — were built.

Miniland is a huge HO scale model railway layout in Munich, Germany. The trains are controlled by a digital control system and the airport has takeoff and landing simulations by model aircraft. The sand tables used are some of the largest in the world. Various German landscapes are miniaturized including the Ruhr area, Zugspitze and the Zugspitze railway. An added feature is the simulation of day and night at regular intervals.
Munich is the capital and largest city of the German state of Bavaria, on the banks of River Isar north of the Bavarian Alps. Munich is the third largest city in Germany, after Berlin and Hamburg and the 12th biggest city of the European Union with a population of above 1.5 million. The Munich Metropolitan Region is home to 5.8 million people. The city is a major centre of art, advanced technologies, finance, publishing, culture, innovation, education, business and tourism in Germany and Europe and enjoys a very high standard and quality of living, reaching No 1 in Germany and No 4 worldwide according to the 2015 Mercer survey. The name of the city is derived from the Old/Middle High German term Munichen, meaning "by the monks". It derives from the monks of the Benedictine order who ran a monastery at the place that was later to become the Old Town of Munich; hence the monk depicted on the city's coat of arms. Munich was first mentioned in 1158. From 1255 the city was seat of the Bavarian Dukes. Black and gold—the colours of the Holy Roman Empire—have been the city's official colours since the time of Ludwig the Bavarian, when it was an imperial residence.

Some background:
The Bell AH-1 SuperCobra is a twin-engined attack helicopter that was developed on behalf of, and primarily operated by, the United States Marine Corps (USMC). The twin Cobra family, itself part of the larger Huey family, includes the AH-1J SeaCobra, the AH-1T Improved SeaCobra, and the AH-1W SuperCobra. The Super Cobra was derived from the single-engine AH-1 Cobra, which had been developed during the mid-1960s as an interim gunship for the U.S. Army. The USMC had quickly taken an interest in the type but sought a twin-engine arrangement for greater operational safety at sea, along with more capable armaments. While initially opposed by the Department of Defense, who were keen to promote commonality across the services, in May 1968, an order for an initial 49 twin-engine AH-1J SeaCobras was issued to Bell. The type entered service during the final months of the US's involvement in the Vietnam War, seeing limited action in the theatre as a result.
The USMC promptly sought greater payload capacity than that provided by the original Sea Cobra; thus the AH-1T, equipped with the dynamic systems of the Model 309 and a lengthened fuselage, was produced by Bell during the 1970s. In the following decade, in response to the denial of funding to procure the Boeing AH-64 Apache attack helicopter, the USMC opted to procure a more capable variant of the AH-1T; equipped with revised fire control systems compatible with new munitions, such as the AGM-114 Hellfire anti-tank missile, the new model, designated AH-1W, commenced delivery in 1986.
In the early 1980s, the Marine Corps sought a new navalized helicopter. Accordingly, it evaluated the Boeing AH-64 Apache attack helicopter as first choice over a two-week period in September 1981, which included shipboard operation tests. Furthermore, various concepts were studied at this time. However, the service's request for funding to purchase the AH-64 was denied by Congress that same year. As an alternative option, the Marines procured a more powerful version of the AH-1T. Other changes included modified fire control systems to carry and fire AIM-9 Sidewinder and AGM-114 Hellfire missiles. The new version, which was funded by Congress, received the AH-1W designation. During March 1986, deliveries of the AH-1W SuperCobra commenced, eventually totaling 179 new-built helicopters along with the upgrading of 43 existing AH-1Ts.
This development also fell into the period when Great Britain was looking for a potential attack helicopter for the British Army, and Western Germany was - together with France - about to mutually develop a new attack helicopter that would in Germany replace the PAH-1, the light Bo 105 helicopter armed with six HOT anti-tank missiles. In 1984, the French and West German governments had issued a requirement for an advanced antitank helicopter, with one variant desired by the French dedicated to the escort and antihelicopter role. As originally planned, both countries would procure a total of 427 helicopters called “Tiger”. The West Germans planned on acquiring 212 models of the anti-tank variant named PAH-2 (Panzerabwehrhubschrauber or "Anti-tank helicopter"), with deliveries starting at the end of 1992. The French wanted 75 HAPs (Hélicoptère d'Appui Protection or "Support and Escort Helicopter") and 140 HACs (Hélicoptère Anti Char or "Anti-Tank Helicopter"), with deliveries starting at the end of 1991 and 1995, respectively. In the meantime, the USA also offered both the AH-1 as well as the more modern AH-64 as alternatives.
Development of the Tiger started during the Cold War, and it was initially intended as a pure anti-tank helicopter platform to be used against a Soviet ground invasion of Western Europe. A joint venture, consisting of Aérospatiale and MBB, was subsequently chosen as the preferred supplier, but in 1986 the development program was already canceled again due to spiraling costs: it had been officially calculated that supplying the German forces with an equivalent number of US-produced McDonnell Douglas AH-64 Apache attack helicopters would have been a considerably cheaper alternative to proceeding with the Tiger’s development, which became a more and more complex project because the helicopter would have to be able to fulfill more roles, and the duty profiles of Germany and France became significantly different. According to statements by the French Defence Minister André Giraud in April 1986, the collaborative effort had become more expensive than an individual national program and was also forecast to take longer to complete.
This opened the door for American proposals even wider, and beyond the state-of-the-art AH-64 Bell proposed a further upgraded two-engine AH-1W. Bell had been working as a private initiative with both the AH-1T+ demonstrator and the AH-1W prototype, and developed a new experimental hingeless rotor system with four composite blades, designed to withstand up to 23 mm rounds and thus greatly improving battlefield survivability. This new main rotor was manually foldable, reduced vibrations and allowed the engine power to be increased, thus greatly improving the SuperCobra’s performance and load capabilities. The twin engine’s power had until then been restricted, but in the AH-1-4BW the power was liberated to full 1,800 shp (1,342 kW), with a reinforced gearbox that could even cope with 2.400 shp. Top speed climbed by 23 mph/37 km/h, rate of climb improved, and the load capability was raised by 1.000 lb (450 kg). The AH-1-4BW was now able to fly a full looping, something the AH-1 had not been able to do before. However, empty weight of this demonstrator helicopter climbed to 12,189 lb (5,534 kg) and the maximum TOW to 18,492 lb (8.391 kg).
Other changes included a different position for the stabilizers further aft, closer to the tail rotor, which furthermore received small end plates to improve directional stability. The modified AH-1W prototype was aptly re-designated “AH-1-4BW” (4BW standing for “4-blade whiskey”), and there were plans to upgrade the type even further with a fully digitalized cockpit to meet contemporary requirements, e.g. for the British Army.
The West-German Bundesluftwaffe’s interest in the “outdated” AH-1 was initially only lukewarm, but when Bell offered to lend the AH-1-4BW prototype for evaluations and as a development mule for the eventual integration of the European HOT missile and indigenous sensors and avionics, a mutual agreement was signed in late 1987 to have the AH-1-4BW tested by the Luftwaffe in the environment where the type would be operated.
The AH-1-4BW prototype (s/n 166 022) was delivered to Manching in Southern Germany in summer 1988 on board of a C-5 Galaxy. It was operated by the Luftwaffe’s Wehrtechnische Dienststelle (WTD, Technical and Airworthiness Center for Aircraft) 61 for two years and successfully made several tests. This program was divided into three “Phases”. “Phase I” included focused on flight characteristics, tactical operations, and mock air-to-air combat against Luftwaffe CH-53s which acted as Mi-24 aggressors. Upon program start the AH-1-4BW received German markings, the registration 98+11, and a new, subdued paint scheme in Luftwaffe colors instead of the original USMC scheme in an overall medium green.
In “Phase I” the AH-1-4BW retained its American weapon systems, as the flight testing did not involve weapon deployment or integration. Instead, dummies or target designators were carried. After these initial tests that lasted almost a year Bell agreed to let the WTD 61 modify the AH-1-4BW further with European avionics to deploy the HOT 3 anti-tank missile, which would be the helicopter’s primal weapon in the German Heeresflieger’s service, since Germany did at that time neither use the similar American TOW nor the more sophisticated AGM-114 Hellfire, even though the German PARS 3 LR missile (also known as TRIGAT-LR: Third Generation AntiTank, Long Range) was already under development since 1988. This upgrade and test program section received the designation “Phase II”. Outwardly, the newly modified AH-1 was recognizable through a different sensor turret in the nose and a modified HOT missile sight for the gunner in the front seat.
In late 1989 the helicopter underwent another modification by WTD 61, which was to test equipment already intended for the PAH-2. Under the trials’ final “Phase III” the AH-1-4BW received a globular fairing on a mast on top of the main rotor, to test the tactical value of observing, identifying, and selecting targets while the helicopter would remain in cover. This sensor mast combined a panoramic IR camera with a targeting sight for anti-tank missiles and the gun turret, and it functionally replaced the standard chin sensor turret (which was brought back to AH-1W standard). Another novel feature was a streamlined, sugar scope-shaped exhaust diffusor with two chambers which guided hot gases upwards into the main rotor’s downwash, as an alternative to the original diffusors which only mixed cold ambient air with the hot efflux. It turned out to be very effective and was subsequently adapted for the Tiger. Other changes included a new hingeless three-blade tail rotor that was supposed to reduce operational noise and frequency issues with the new 4-blade main rotor, and the endplate stabilizers were enlarged to compensate for the huge “eyeball” on top of the main rotor which significantly changed the AH-1’s flight characteristics, especially at high speed.
Further tests of the Phase III SuperCobra lasted until summer 1990 and provided both Bell as well as the Luftwaffe with valuable benchmark data for further weapon system developments. When the lease contract ended in 1991, the AH-1-4BW was sent back to the United States. In the meantime, though, the political situation had changed dramatically. The USSR had ceased to exist, so that the Cold War threat especially in Europe had ended almost overnight after the Aérospatiale/MBB joint venture, now officially called Eurocopter, had signed an agreement in 1989 which financially secured the majority of the Tiger’s pending development through to serial production, including arrangements for two assembly lines to be built at Aerospatiale's Marignane plant and MBB's Donauwörth facility. This eventually saved the Tiger and in 1991 it had become clear that no American attack helicopter would be bought by either Germany or France. Great Britain as another potential European customer also declined the AH-1 and eventually procured the more modern AH-64 in the form of the license-built AgustaWestland Apache.
In 1992, the Eurocopter Group was officially established, and the Tiger moved closer to the hardware stage; this led to considerable consolidation of the aerospace industry and the Tiger project itself. A major agreement was struck in December 1996 between France and Germany that cemented the Tiger's prospects and committed the development of supporting elements, such as a series of new generation missile designs for use by the new helicopter. National political issues continued to affect the prospects of the Tiger, however. A proposed sale of up to 145 Tigers to Turkey proved a source of controversy; Turkey selected the Tiger as the preferred option, but conflicting attitudes between Eurocopter, France and Germany regarding military exports led to Turkey withdrawing its interest. Eventually, Turkey procured AH-1s and started an indigenous attack helicopter program.
However, the AH-1-4BW’s development and its vigorous testing in Germany were not in vain: Lacking a USMC contract, Bell developed this new design into the AH-1Z with its own funds during the 1990s and 2000s. By 1996, the Marines were again prevented from ordering the AH-64: developing a marine version of the Apache would have been expensive and it was likely that the Marine Corps would be its only customer. Instead, the service signed a contract for the upgrading of AH-1Ws into AH-1Zs, which incorporated many elements from the AH-1-4BW.

The kit and its assembly:
This what-if model was inspired by the real attempts of Bell to sell a twin-engine Cobra variant to Germany as a replacement for the light PAH-1/Bo 105 helicopter, while plans were made to build an indigenous successor together with France which eventually became the PAH-2/Tiger. These proposals fell well into the time frame of the (also) real AH-14BW project, and I imagined that this specific helicopter had been lent to the Luftwaffe for evaluation?
The basis is the Italeri 1:72 AH-1W kit, a solid basis which requires some work, though. And because I had the remains of a French Tigre at hand (which gave its cockpit for my recent JASDF A-2 build) I decided to use some of the leftover parts for something that borders a kitbashing. This includes the 4-blade main and 3-blade tail rotor, and I integrated the Tiger’s scoop-shaped exhaust diffusor behind the main rotor – a tricky task that require a lot of PSR, but the result looks very natural, if not elegant? The Tiger’s end plate stabilizers were used, too, mounted to the AH-1’s trim stabilizers that were mounted further back, as on the real AH-1-4BW.
To change the look even further I decided to add a sensor pod on top of the main rotor, and this required a totally new mechanical solution to hold the latter. Eventually I integrated a sleeve for a fixed metal axis which also holds the sensor ball (from a MisterCraft Westland Lynx – a bit oversized, but suitable for a prototype), and the PAH-2 rotor received an arrangement of levers that hold it in place and still allow it to spin.
The ordnance was also taken from the Italeri Tigre, with HOT quadruple launchers for the outer weapon stations, the inner hardpoints were left empty and I also did not mount the American chaff/flare dispensers on top of the stub wings.
Painting and markings:
The Luftwaffe did a LOT of interesting camouflage experiments in the early Eighties, adopting several standardized schemes for aircraft, but the Heeresflieger were less enthusiastic and retained the overall Gelboliv (RAL 6014) scheme before a three-color camouflage, consisting of two green tones and a dirty black was gradually introduced – even though apparently not in a uniform fashion, because there were variations for the darker shade of green (retaining RAL 6014 or using FS 34079, as on the Luftwaffe Norm ’83 scheme that was applied to Tornado IDSs, RF-4Es, some Starfighters and to the Transall fleet).
My fictional AH-1-4BW would fall into that transitional phase and I decided to give the helicopter an experimental scheme, which was used/tested on early Tornado IDS, consisting of RAL 7021 (Teerschwarz), RAL 7012 (Basaltgrau) and RAL 6014 (Gelboliv) – on aircraft with undersides in RAL 7000 (Silbergrau), but on a helicopter rather as a wraparound scheme. However, inspired by Luftwaffe F-4Fs with a modified Norm ‘72 splinter scheme that added a simple light grey fin to break up the aircrafts’ profile in a side view, I used RAL 7030 (Steingrau) on the tail tip to achieve the same effect, and the light grey was also used, together with Basaltgrau und Gelboliv mottles on the sensor ball – looks a bit like WWII Luftwaffe style, but appeared plausible for the system’s tactical use from behind some ground cover. The cockpit interior became very dark grey, just like the rotor blades, which were adorned with orange warning markings at the tips – seen on some Luftwaffe helicopters instead of classic yellow or red-white-red bands.
The decals were puzzled together from various sources. National markings came from generic Luftwaffe sheets from TL Modellbau, the light blue WTD 61 emblems behind the cockpit were taken from a Peddinghaus decal sheet with early Luftwaffe unit markings. The dayglo panels were created with generic decal material (TL Modellbau, too) and stencils came mostly from a Fujimi AH-1 sheet, procuring German or even multi-language material appeared too tedious and costly.
The photo calibration markings on nose and fins were improvised from black and white decal sheet material, punched out, cut into quarters, and then applied as circles. Adds an experimental touch to the Cobra!
The kit received a light black ink washing and some post-panel-shading, esp. to brighten up the grey and increase the contrast between the camouflage tones, which appeared even more murky after the dayglow stripes had been added. Finally, the Cobra received an overall coat wit matt acrylic varnish, position lights were added/painted, and the sensor ball received sights made from yellow chrome PET foil, simply punched out and fixed into place with some Humbrol Clearfix.
This one took a while to materialize and was more work than one might expect at first glance. But it looks quite cool, esp. the PAH-2/Tiger’s exhaust fairing fits very well into the Cobra’s lines and adds an elegant touch to the helicopter. The “Eye ball” is a bit large, yes, but IMHO acceptable for a prototype or test vehicle. And the livery certainly conveys a German touch.

Historic Environment Record for H BUILDING, Malvern, UK
The building, having military purposes and designated locally as H building, sits on a former Government Research site in Malvern, Worcestershire at Grid Ref SO 786 447. This site was the home of the Telecommunications Research Establishment (TRE) from 1946. It has been owned by QinetiQ since 2001 and is in the process (October 2017 to February 2018) of being sold for redevelopment.
This unique building has at its heart a ‘Rotor’ bunker with attached buildings to house radar screens and operators as well as plant such as emergency generators. Twenty nine Rotor operational underground bunkers were built in great urgency around Britain to modernise the national air defence network, following the Soviet nuclear test in 1949. Two factors make H building’s construction and purpose unique; this prototype is the only Rotor bunker built above ground and it was the home to National Air Defence government research for 30 years.This example of a ROTOR bunker is unique instead of being buried, it was built above ground to save time and expense, as it was not required to be below ground for its research purpose.
H Building was the prototype version of the Rotor project R4 Sector Operations Centre air defence bunkers. Construction began in August 1952 with great urgency - work went on 24 hours a day under arc lights. The main bunker is constructed from cross bonded engineering bricks to
form walls more than 2 feet thick in a rectangle approximately 65ft x 50ft. The two internal floors are suspended from the ceiling. The original surrounding buildings comprise, two radar control and operator rooms, offices and machine plant.
The building was in generally good order and complete. The internal layout of the bunker remains as originally designed. The internal surfaces and services have been maintained and modernised over the 55 years since its construction (Figure 3). The first floor has been closed over.
There are some later external building additions around the periphery to provide additional accommodation.
In parts of the building the suspended floor remains, with 1950s vintage fittings beneath such as patch panels and ventilation ducts.
The building has been empty since the Defence Science & Technology Laboratories [Dstl] moved out in October 2008
As lead for radar research, RRE was responsible for the design of both the replacement radars for the Chain Home radars and the command and control systems for UK National Air Defence.
Project Rotor was based around the Type 80 radar and Type 13 height finder. The first prototype type 80 was built at Malvern in 1953 code named Green Garlic. Live radar feeds against aircraft sorties, were fed into the building to carry out trials of new methods plotting and reporting air activity
A major upgrade of the UK radar network was planned in the late 1950s – Project ‘Linesman’ (military) / ‘Mediator’ (civil) – based around Type 84 / 85 primary radars and the HF200 height finder. A prototype type 85 radar (Blue Yeoman) was built adjacent to H Building in 1959. live radar returns were piped into H Building.
Subsequently a scheme to combine the military and civil radar networks was proposed. The building supported the research for the fully computerised air defence scheme known as Linesman, developed in the 1960s, and a more integrated and flexible system (United Kingdom Air Defence Ground Environment or UKADGE) in the 1970s.
The building was then used for various research purposes until the government relinquished the main site to QinetiQ in 2001. Government scientists continued to use the building until 2008. Throughout its life access was strictly controlled by a dedicated pass sytem.
Notable civil spin-offs from the research in this building include the invention of touch screens and the whole UK Civil Air Traffic Control system which set the standard for Europe.
Chronology
1952 - Construction work is begun. The layout of the bunker area duplicates the underground version built at RAF Bawburgh.
1953 - Construction work is largely completed.

TOUCHSCREEN
A team led by Eric Johnson in H building at Malvern. RRE Tech Note 721 states: This device, the Touch Sensitive Electronic Data Display, or more shortly the ‘Touch Display’, appears to have the potential to provide a very efficient coupling between man and machine. (E A Johnson 1966). See also patent GB 1172222.
Information From Hugh Williams/mraths
1980-1990 - During this period experiments are moved to another building and H building is underused.
1990-1993 - The building was re-purposed and the bunker (room H57) had the first floor closed over to add extra floor area.
2008- The bunker was used until late 2008 for classified research / Joint intelligence centre
2019 - Visual Recording of the buildings interior by MRATHS. Be means of a LIDAR scan and photographs being taken. The exterior was mapped with a drone to allow a 3D Image of the building to be created via Photogrammetry. This was created in Autodesk Photo Recap.
2020 - Building demolished as part of the redevelopment of the site.
