Greetings All -

A few scans of photos found in the archives but not sure which model it is. Any suggestions?

Enjoy the Day! Mark

Could it be

V-521 (29-12-1971) VTOL fighter/attack aircraft with three engines - one lift/cruise plus 2 lift units [Tony Buttler - American Secret Projects: Jet Fighters]

Described as a canard delta with lift/lift-cruise engines in the Vought Docavia, seems pretty likely.

Presumably it was an alternative to the V-517/520 design.

Well, on my first sight, it looked very similarly to the "Convair Model 200 VSTOL Navy Fighter ".
But now I see a few differences, especially the aft part with that one lift/cruise engine configuration.

Greetings All!

Some drawings to go along with the photos, thanks of course to the Vought Archives.

Enjoy the Day! Mark
