No, but somewhat similar.

Appearing viable without ailerons seems to rule out a delta wing in favor of a variable sweep-wing design…

12. The lack of ailerons was due to the designers' incorporating full-span flaps. This was in response to a ridiculous short-takeoff requirement that was later dropped.

Oh wow. I actually looked at that one briefly but moved on thinking there's no way it wouldn't have ailerons. But upon review, it lines up almost perfectly with the clues.

I love that plane, but I think I'll let someone else answer.

Has to be the RA-5C Vigilante. Was designed as a supersonic bomber with bombs being dropped out of the rear of the plane. Failed in that role but excelled as a high speed recon bird. Flew a small amount of bombing missions but flew a lot of recon missions over Viet Nam, operating from the various aircraft carriers assigned to provide air support. It had the highest loss per sortie average of any aircraft in use at the time

Originally designated A3J. The original specification called for it to be able to be launched from a carrier that was moored to a pier. That's how it got it's massive wing area and full-span blown flaps. Five years after initial procurment, it was put back into production due to it's high attrition rate. When landing, it was said to be absolutely unforgiving at the ramp. It was also one of the very first "fly-by-wire" aircraft, ten years before the term even came into common use. One of many Mach 2 airplanes to be powered by GE's wonderous J79. Over to you, HJ.

Okay guys, had to think a bit on this one. I doubt this one will last long
1) Aircraft used engine developed in another country

I think there are many, but a quick few: P-51 (US aircraft using British engine). SPAD (French aircraft using Spanish engine). Sopwith various (British aircraft using French engines)

There were British aircraft that used American engines, as well.

I'll hazard a guess, here: MiG-15.

I knew it would go quick but never expected that quick.
The Mig-15 used an engine developed by Rolls Royce. The plans for a RR Nene were given to a Russian as a payoff to a bet, so one story goes, over a game of Billiards. Another is that twenty-five were given to the Soviet Union as a gesture of goodwill - with reservation to not use for military purposes - with the agreement of Stafford Cripps. The Soviets reneged on the deal, and reverse engineered the Nene to develop the Klimov RD-45, and a larger version, theKlimov VK-1, which soon appeared in various Soviet fighters including Mikoyan-Gurevich MiG-15

Stalin asked "What fool sells his own secrets?" when told of the engine deal. The Brits were desperate for any foreign trade at the time, being essentially bankrupted by WW2. I'll need a bit of time to come up with a question.
