Found via google patent search. Northrop design, seems to be related to early stages of AX.
I worked at Northrop (now Northrop-Grumman) in the 1980s.
When I visited the March AFB/ARB Air Museum, I finally
got my first chance to see and touch one of the A-9A prototypes.
The most unusual variant of the A-9A proposed was a
desktop 1/48th scale model of a PROPELLOR version of
the A-9A. The propellor arrangement was a PUSHER
configuration, with 3 tail fins arranged in a Y shaped
configuration: 1 ventral fin, 2 angled dorsal fins.
I am not sure what they had in mind with that concept
model - perhaps a slower, Skyraider type attack craft.

The Southern California Historical
Aviation Foundation (SCHAF) has
proudly announced the arrival of
"Sierra Sue" at their Western Museum of
Flight in Hawthorne, California, where
it will be on display for an undetermined
period of time. A unique "pusher"
aircraft with a single propeller in
back of its tail, Sierra Sue was designed
and built in the 1950s as a race plane
by engineers at North American and
Northrop in their spare time. In the
late 1960s, it served as a concept
demonstrator in developing a prototype
attack aircraft for the U.S.Air Force, but
the design was dropped when the Air
Force announced its requirement for a
jet, rather than a propeller aircraft.
