Two jet projects found in the Ryan Reporter, Vol. 13, No.5 (August 1, 1952).
They are described as NACA projects but to me they look pretty Lockheed-ish, like something halfway between F-90 and F-104 with glimpses of Suntan...
From Army Aviation 1956/9.
Not sure, but the wing makes it look like a development of the Fairchild M-224 Fledgling (VZ-5).I can't ID the second concept from which company ?,far right.
