Vought A-7A Corsair II
The A-7A Corsair II was designed as a lightweight attack aircraft to supplement and later replace the Douglas A-4 Skyhawk. In addition to service in the US Navy, Corsair II's were flown by the US Air Force, Air National Guard, and several other nations. The A-7 production line started on 19 March 1964 and continued until September 1984; 1,545 were built. Its first flight, powered by a Pratt & Whitney TF3O-P-6 turbofan engine, was on 27 September 1965. Navy Preliminary Evaluations were underway in January 1966. Test programs were accomplished with wartime urgency, and the first fleet delivery (VA-174) was on 14 October 1966. Retirement of the last two Navy A-7 aircraft fleet operational squadrons (VA-46 and VA-72) was in May 1991.
About this creation

This picture represents the current state of the model. I'm slowly fine-tuning the design, but notable changes include a more accurate placement of the twin 20mm single cannons on either side of the forward lower fuselage "cheeks", the corrected stance of the aircraft in relation to the ground, and some small cleanups to the color scheme. I will update the other pictures as time allows to reflect these changes.




Front view showing the upward curve of the inside of the intake, and the bump on the lower left fuselage "cheek" for the port 20mm single barreled cannon. The A-7A and B models featured 2 of these cannons, but had them replaced by a single port-mounted GE M-61A1 6-barreled 20mm rotary cannon on the later E model and Air Force/ANG D and K models.












Closeup of the main gear. I've reinforced the design, although without real world testing I'm unsure if the model would be self-supporting. I strove for accuracy and functionality over strength in this area. I'm still quite pleased with the end result.




View of the upward hinging radome. Unlike my other models, the rather small radome on this model did not leave enough room for a radar antenna to fit inside, so I had to omit that detail. I have considered having a removeable one that could be placed on the model for display with the nose open, but I tend to dislike that option.


The Naval style inflight refueling probe in the extended position. The Navy uses the probue and drogue style of inflight refueling, requiring the aircraft to be manually flown into a basket recepticle trailed behind a tanker aircraft on a hose. While more challenging than the Air Force's "flying boom" style of refueling, it allows much smaller aircraft to be used as tankers. This is a necessity for carrier operations.


Clean view of the model with all gear stowed and the canopy closed. The A-7, like it's predecessor the F-8 Crusader, has its missile launch rails for AIM-9 Sidewinder air to air missiles mounted on the sides of the fuselage. This frees up space on the wing pylons for further ordinance or fuel tanks. for it's size, the A-7 could carry an astounding amount of weaponry, had excellent range and loiter time, and at the time of its inception was the most advanced attack aircraft in the arsenal. It also pioneered the use of the HUD (Heads Up Display).


The large ventral airbrake is deployed in this view, and the flaps have been lowered and ailerons both lowered (incorrect from a functional standpoint, but more illustrative in this case).


Rear view showing the ventral airbrake again, the deployed tailhook for carrier operations, moving control surfaces, and the rather small exhaust. The A-7 was firmly subsonic and lacked a large afterburner or moving exhaust vanes, commonly known as "turkey feathers" found on fighter aircraft. the small red object on the lower left fuselage just behind the main gear is a fuel dump port.






This picture shows the folding outer wingtips for carrier storage. The A-7 shares many basic design traits with the F-8 Crusader, although optimised for the attack role instead of the air superiority role.


The black areas on the upper rear fuselage are nonskid coated service areas for aircraft maintenance personnel. Naval aircraft frequently feature these due to the nature of sea based operations.

Excellent work on the cockpit. The details are amazing. I can't wait to see what you make next!

Amazing piece of work; without doubt one of the best planes on this site. The work on the landing gear is extraordinary, but I fear it could not take the weight if built in plastic bricks. One of the advantages of doing building on the computer I suppose!

Whao! I added your main landing gear to my classic MOCs collection. Congratulations. Cockpit canopy and air intake are also great work. Could the main landing gear really support the models weight? (If not, its not a problem, very hard to do from ABS).

Quoting Matt Bace Very nice! I have to agree with Clayton -- the landing gear are especially well done. You've also done a great job replicating that big ugly intake in the front, and the shaping every else appears to be spot on.
The main gear took several tries to get to look right, fold correctly, and stow deeply enough to allow the gear doors to close. Lots of trial and error, probably half the build time was spent on that general area of the model. Once I got it down the rest filled in fairly easily, if not slowly.

Beautiful job! You don't see this very often in lego. I really like the landing gear. Excellent shaping on the fuselage and I like how you made the canopy . Amazing work!
