So I precrease this black sheet of paper, and start to fold this waterbomb-based tessellation: flickr.com/photos/brdparker/2964984654/
It's really difficult without angle bisector precreases! So I finish 7 hexagons worth of the pattern, and think, okay from here, I'll go out and make a flat pleat-pattern, see what comes out.
There's some really interesting stuff happening here. I wish I had enough room on the paper to put another "cusp," as I've come to call it adjacent, but this looks pretty cool as sits.
The curved part, the cusp, is a WBTess, which, if I were using infinitely thin paper, would be flat like the rest of the pattern, but since the paper has thickness, there's a fairly dramatic curve, as you can see.
The flat pattern itself had an interesting progression itself. Emerging from the corners of the cusp are 3.6.3.6. tilings of twists, but it's a radial design. There is spacing between the parts, which I thought was pretty neat.
Unfortunately (stupid stupid!) I used that amazing black paper, which is still not-backlightable... grr...
Hopefully, I'll be able to apply this sort of thing (that is, surround a design with twists and locks) to more WBTesses to create more solidified pieces that don't mind being abused a little before they fall apart.

Quantico Docks. They are part of the base, but to get to them you must go through the town of Quantico which as an area of a half mile.
Marine Corps Base Quantico is located near Triangle, Virginia. Known as the "Crossroads of the Marine Corps", it is a major Marine Corps training base, covering nearly 100 square miles. The Corps' Combat Development Command is based here, which develops strategies for Marine combat, and makes up most of the community of over 12,000 military and civilian personnel, including families. It has a budget of around $300 million. The Marine Corps Research Center at Quantico pursues equipment R&D, especially telecommunications, for the Marine Corps. In addition, the FBI has its principal research and training facilities here, including a mock village, numerous labs, and equipment test ranges. Quantico is also the principal training facility for the Drug Enforcement Administration (DEA).
t is the site of the Marine Corps Combat Development Command and Marine Helicopter 1 HMX-1. HMX-1 was the first helicopter squadron to provide rapid transportation of U.S. Presidents. A mission they have continued to carry out to the present day.

Since its inception in 1917, Marine Corps Base, Quantico, has been the "frontline of innovation." Marine concepts, doctrine, training, and equipment of the future are initiated aboard the Base. The techniques of amphibious warfare, for which the Corps is renowned, were conceived and perfected here. The tactics of close-air support and vertical envelopment using helicopters were also developed within its borders. As attention is focused on future battlefields, the Marine Corps and other branches of Service are looking to Quantico to lead the way with technological advances as well as creative and innovative thinking.
Quantico also serves as the focal point for professional military education. The Marine Corps University provides the academic platform the Corps uses to shape and hone leaders at every milestone of their professional lives. Officers in the Marine Corps begin their careers at the Officer Candidates School and The Basic School. Enlisted marines receive additional leadership training at the University's Staff Non-Commissioned Officers Academy. The Marine Corps War College, School of Advanced Warfighting and Amphibious Warfighting School are also part of the University, training officers in the U.S. Armed Forces and international officers from designated foreign countries in the art of war.
Whether assigned to Quantico as a student or as a permanent personnel, you will become part of a community that reflects professional character while enjoying an off-duty environment with many social, civic, and professional opportunities.
Marine Corps Base Quantico is home to the Marine Corps Combat Development Command and numerous tenant organizations. The base staff provides infrastructure, operational, and community services support to these organizations and to the military members, families, and civilians who live and work on base. The base is also a key player in support of overall Marine Corps objectives and programs, and plays host to scores of training events, conferences, symposia, and other special events.

Some background:
The North American A-5 Vigilante (Prior to 1962 unification of Navy and Air Force designations, it was designated the A3J) was an American carrier-based supersonic bomber designed and built by North American Aviation for the United States Navy. In 1953, North American Aviation began a private study for a carrier-based, long-range, all-weather strike bomber, capable of delivering nuclear weapons at supersonic speeds. This proposal, the North American General Purpose Attack Weapon (NAGPAW) concept, was accepted by the United States Navy, with some revisions, in 1955. A contract was awarded on 29 August 1956. Its first flight occurred two years later, on 31 August 1958 in Columbus, Ohio.
At the time of its introduction, the Vigilante was one of the largest and by far the most complex aircraft to operate from a Navy aircraft carrier. It had a high-mounted swept wing with a boundary-layer control system (blown flaps) to improve low-speed lift. It had no ailerons; roll control was provided by spoilers in conjunction with differential deflection of the all-moving tail surfaces. The use of aluminum-lithium alloy for wing skins and titanium for critical structures was also unusual. The A-5 had two widely spaced General Electric J79 turbojet engines, fed by inlets with variable intake ramps, and a single large all-moving vertical stabilizer. Preliminary design studies employed twin vertical fin/rudders, but this was eventually changed to a single tall but foldable fin. The wings and the nose radome folded for carrier stowage, too. The Vigilante had a crew of two seated in tandem, a pilot and a bombardier-navigator (BN) (reconnaissance/attack navigator (RAN) on later reconnaissance versions).
The Vigilante had advanced and complex electronics when it first entered service. It had one of the first "fly-by-wire" systems on an operational aircraft (with mechanical/hydraulic backup) and a computerized AN/ASB-12 nav/attack system incorporating a head-up display ("Pilot's Projected Display Indicator" (PPDI), one of the first), multi-mode radar, radar-equipped inertial navigation system (REINS, based on technologies developed for North American's Navaho missile), closed-circuit television camera under the nose, and an early digital computer known as "Versatile Digital Analyzer" (VERDAN) to run it all.
The aircraft replaced the subsonic Douglas A-3 Skywarrior as the Navy's primary nuclear-strike aircraft, but only briefly. Given its original design as a carrier-based, supersonic, nuclear heavy attack aircraft, the Vigilante’s main armament was carried in an unusual internal "linear bomb bay" between the engines in the rear fuselage, which allowed the bomb to be dropped at supersonic speeds. The single nuclear weapon, commonly the Mk 28 bomb, was attached to two disposable fuel tanks in the cylindrical bay in an assembly known as the "stores train". A set of extendable fins was attached to the aft end of the most rearward fuel tank. These fuel tanks were to be emptied during the flight to the target and then jettisoned with the bomb by an explosive drogue gun. The stores train was propelled rearward at about 50 feet (15 m) per second (30 knots) relative to the aircraft. It then followed a ballistic path.
The Vigilante originally had two wing pylons, intended primarily for drop tanks. The second Vigilante variant, the A3J-2 (A-5B), incorporated internal tanks for an additional 460 gallons of fuel, which added a pronounced dorsal "hump", along with two additional wing hardpoints, for a total of four. Other improvements included blown flaps on the leading edge of the wing, changes to the air intakes and stronger landing gear.
The reconnaissance version of the Vigilante, the RA-5C, was based on the A-5B airframe and had slightly greater wing area and added a long canoe-shaped fairing under the fuselage for a multi-sensor reconnaissance pack. This added an APD-7 side-looking airborne radar (SLAR), AAS-21 infrared line scanner, and camera packs, as well as improved electronic countermeasures. An AN/ALQ-61 electronic intelligence system could also be carried. The RA-5C retained the AN/ASB-12 bombing system, and could, in theory, carry weapons, although it never did in service. Later-built RA-5Cs had more powerful J79-10 engines with afterburning thrust of 17,900 lbf (80 kN), the same engines as the Navy’s F-4J Phantom IIs. The reconnaissance Vigilante weighed almost five tons more than the strike version with almost the same thrust and an only modestly enlarged wing. These changes reduced its acceleration and climb rate, though it remained fast in level flight and was still fully carrier-capable.
The last Vigilante version to be developed from 1964 on and to enter service in 1966 was the EA-5D, a dedicated electronic reconnaissance and electronic warfare version, again replacing respective A-3 Skywarrior variants. With the initial experience from the Vietnam conflict, the EA-5D was primarily conceived as a fast escort for supersonic strike aircraft – namely the USN’s F-4 Phantom IIs which progressively took over more strike missions and direly needed protection from SAMs that could keep up with them during their dangerous missions over enemy territory.
The EA-5D, which was unofficially nicknamed “Electric Vigilante”, “Eva” or simply “E-V” by its crews, was based on the late RA-5C’s airframe and was easily distinguishable through its fairing at the top of the fin which contained the electronics for a Bunker-Ramo AN/ALQ-86 ECM suite. It carried ECM gear in the linear bomb bay and a 16 feet (4.9 m) long canoe-shaped ventral fairing (looking like a shortened but deeper version of the RA-5C’s camera and SLAR installation), plus a heat exchanger, a non-jettisonable auxiliary tank and AN/ALE-41 chaff dispensers in an extended tail cone. The complete installation weighed some 6,000 pounds (2,700 kg). Receivers were installed in a fin-tip pod, or "football", like that of the contemporary EA-6A. This fin array caused some lateral instability, though, which could be compensated with a pair of fins under the rear fuselage.
Like the RA-5C, the EA-5D retained the AN/ASB-12 bombing system and was – in theory – like its recce sibling capable to carry out strike missions, but this never happened either. The EA-5Ds were furthermore equipped with an AN/APQ-129 fire control radar, making the aircraft capable of SEAD missions and of firing the AGM-45 “Shrike” anti-radiation missile, although they were apparently never used in that offensive role. Up to four ram-air turbine powered ALQ-76 countermeasures pods could be carried on the underwing hardpoints, augmenting the internal AN/ALQ-86 system’s bandwidth and jamming power. To improve survivability the EA-5D was furthermore outfitted with a pair of launch rails, mounted as sub-pylons on the outsides of the outer underwing hardpoints. Each could carry a single IR-guided AIM-9 Sidewinder AAM.
Despite the Vigilante's useful service as reconnaissance and ECM platform, it was expensive and complex to operate and occupied significant amounts of precious flight and hangar deck space aboard both conventional and nuclear-powered aircraft carriers at a time when carrier air wings, with the introduction of the F-14 Tomcat and S-3 Viking, were averaging 90 aircraft, many of which were larger than their predecessors. Moreover, the Vigilante did not end the career of the A-3 Skywarrior, which would carry on as photo reconnaissance aircraft, electronic warfare platforms, aerial refueling tankers, and executive transport aircraft designated as RA-3A/B, EA-3A/B, ERA-3B, EKA-3B, KA-3B, and VA-3B, into the early 1990s.
Only 28 EA-5Ds were built (two prototypes, 15 new-build, and 11 conversions from existing A-5A and RA-5C airframes) and the United States remained the only operator of the type. The EA-5D saw extensive use in Vietnam and seven machines were lost (four to SAMs, one to a VPAF MiG-21 and two through accidents), but after the end of hostilities and massive reductions of military expenses the EA-5D was quickly phased out from frontline service in the late 1970s, after an active career of just twelve years. In service it was replaced by the subsonic but much more potent EA-6B “Prowler”, which was based on the carrier-capable A-6 “Intruder” bomber, primarily to reduce the number of types in the USN’s arsenal and therewith operating costs and complexity. Since the EA-6B offered much higher ECM capabilities, the small EA-5D fleet was never upgraded, e. g. with the 2nd generation AGM-78 “Standard” ARM or the AN/ALQ-99 ECM pods.
However, a handful of “Electric Vigilantes” remained active with VAQ-137 (“Rooks”) until the late Eighties – long enough to receive the USN’s new tactical low-visibility paint scheme. These EA-5Ds were operated from land-bases only, not assigned to a Carrier Air Group, with a dedicated tail code (“KW”) to reflect this special status. They acted primarily as electronic aggressor aircraft but were also used to simulate supersonic cruise missiles like the contemporary Soviet Kh-20 (AS-3 “Kangaroo”) or Kh-22 (AS-4 “Kennel”) against land and sea targets during training and naval NATO maneuvers. Thanks to their size, speed and flight characteristics the aircraft were also employed as supersonic bomber aggressors, mimicking Soviet Tu-22s or Su-24s. Most of the Evas therefore received more or less authentic temporary Red Star decorations on their fins, which were, however, rarely overpainted after training missions and became part of the “standard markings”.
In 1987 the machines were finally retired, their airframes had reached their structural limit and maintenance costs of the complex aircraft had become prohibitive. They were in the electronic aggressor role eventually replaced with subsonic and much more economical EA-7L Corsair IIs.

The kit and its assembly:
This what-if project had been lingering for a long time in the back of my mind, and I shoved it a side for years because of the model’s sheer size that eats up a lot of display space – even though I had the hardware already stashed away, collecting dust. While the build was rather inspired by its livery (see below) I wondered why the Vigilante, an elegant and impressive aircraft, had not been adapted to the ECM role? The concept of a supersonic penetrator/protector aircraft was realized by the USAF with the EF-111A Raven, but in the Vigilante’s time frame, the Vietnam War, esp. its end phase, an escort for fast USN attack aircraft might have made sense, so that I tried to mate the RA-5C with contemporary ECM technology and typical details – and the result became the fictional EA-5D.
With this idea the model became only a conversion of a basic airframe, not a spectacular kitbashing. Since I knew the Hasegawa RA-5C and its underwhelming quality/detail, I settled for the Trumpeter kit – a MUCH better but also a bit über-complicated offering. It is, however, better in any respect, even though you can ask why the cockpit has to consist of no less than thirty (!) parts (including seats and dashboard films), and the pylons as well as even the thin stabilizers and the fin have to consist of halves? One can also wonder why the kit comes with four(!) free-fall nukes but none of the RA-5C’s typical 400 gallon drop tanks? The kit features the type’s underwing flare dispensers, though. If there is something to criticize it’s the lack of air intake ducts – behind the wedge-shaped intakes and their ramps there is nothing inside the fuselage. Since I did not want to put too much effort into that flaw I simple blocked sight into the model’s body with a bulkhead made from black foamed styrene.
Everything goes together quite well, except for the fuselage halves which appear somewhat warped, and the rather massive plastic makes work easy. Despite this splendor of material, the sandwich leading and trailing edges are surprisingly thin and look pretty good.
While the RA-5C was at its core built OOB there were – naturally – some external mods to convey its ECM role. Most obvious detail is the fin top fairing, procured from a KiTech EA-6B, a shabby copy of the Hasegawa kit. This also provided the ECM pods and the pair of voluminous drop tanks.
The retrofitted Sidewinder launch rails on the outer pylons came from an Emhar FJ-4B, the then-state-of-the-art all-aspect AIM-9Ls came from a Hasegawa F-4 kit. To emphasize its electronic mission I added some antenna fairings around the hull. Beyond the fin pod, the EA-5D received sensor fairings along the flanks, inspired by the USAF F-105Gs’arrangement along the bomb bay, a shallow dorsal bulge behind the cockpits and some blister and blade antennae all around the hull.
The large ventral fairing that replaced the RA-5C’s “camera canoe” was scratched from a drop tank half, from a chunky Kangnam MiG-31, in an attempt to create something that the reminds of the EF-111’s arrangement. A ventral adapter for a display holder was integrated into the hull, too, for in-flight scenes.
A pair of long stabilizer fins was added under the rear fuselage, too, because I think that the large tail fin pod could somewhat hamper directional stability… The consist of rotor blades from a Matchbox SA.360 Dauphin helicopter.
The Vigilante’s tail cone, the former fairing for the linear bomb bay between the engines, was also heavily modified, with a thimble-shaped radome and a separate fairing for an internal chaff dispenser underneath, for a different look. To make the model look a bit more lively, esp. in its all-grey low-viz livery (see below) I mounted the flaps (all six are separate elements, and the inner pairs consist of lower and upper halves, too!) in lowered position.
Painting and markings:
The original reason to build this whiffy Vigilante was to see how the sleek and elegant aircraft would look in early USN low-viz colors! With this idea in mind the scheme was improvised and very simple: FS 36320 on the upper surfaces and FS 36375 underneath (Humbrol 128 and 127, respectively), on the flanks (with a relatively high waterline) and the fin. A slightly darker blue grey (FS 35237, Humbrol 145) was used for an anti-glare panel in front of the windshield. Most di-electric panels and the nose radome were painted in brownish light grey (RAL 7032, Revell 75), for low contrast but a significantly different color.
Inside, the landing gear as well as the air intakes were painted gloss white, the cockpit was painted in neutral grey (FS 36231) with dark grey ejection seats. The latter appears a bit tone-in-tone with the all-grey outside, but that was apparently the A-5’s interior design in real life.
To add some variety to the grey livery I painted the ordnance in “old” USN colors: the drop tanks became all-white and the ECM pods also received a white base. The AIM-9Ls on the extra launch rails (also painted white) received blue bodies as training missiles, with black seeker heads and white tail fins.
The wings’ leading edges (bare steel?) were masked and then painted with Revell 91 (iron metallic).
The whole model received a washing with thinned black ink to emphasize the many recessed rivets and panel lines, and then I added panel counter shading with lighter basic tones, also trying to create a slightly worn/weathered and not-so-uniform finish on the large grey surfaces, which underline the Vigilante’s elegant lines but also look quite boring, due to the sheer size/area, esp. from above.
The low-viz markings were improvised and puzzled together from various sources. The Red Stars on the fin were inspired by real-world aggressor markings, AFAIK some A-7Ls, EA-3Bs and A-4Fs carried such decorations, even paired with large bort numbers on the nose.
To improve the worn/grimy look I also treated the model’s surfaces with grinded graphite – only lightly, but I wanted to make the large grey areas to look even more diverse than just with the initial paint effects.
