Planform is very similar to XF-103. Nice find.

This links MX-1764 to other Republic designs e.g. AP-75

Great find my dear Paul.

Thank you my dear Paul,


and finally,that list makes us know that mystery designation.

 

[hesham]

From Air Pictorial 9/1955,


they mentioned a competition for long-range bomber interceptor,and a preliminary
design and mock-up contracts had been awarded for Lockheed,North American and
Northrop,did they mean this contest or WS-202A (XF-108) contender ?.


That's question because they added the word "bomber" in the description.

How to get it again,that's PDF ?,and what about my suggesting if it
was the same WS-202A or not ?.

 

[overscan (PaulMM)]

Updated PDF links.

October 1955 contracts to Lockheed, North American and Northrop was LRI-X / WS-202A

Many thanks to you my dear PaulMM,

and obviously North American D-222 was a preliminary concept,and they
later submitted D-235,D-264 & D-271 as a final proposals.

 

[A Tentative Fleet Plan]

One of North American's MX-1764 proposals appears in Tony Buttler's article, North American's class of '54: North American Special Aviation Project June 1954, The Aviation Historian Issue No 45.

Looks like a scaled-down version of their single-tailed WS-302A proposal, with a single J79.
