Thanks for this tread ... here are two illustrations of this twin-engined version !

It had the same fascinating tail shape as Ye-152A.

Ah I see these beat me here. There was also a proposal for a two seat, twin engine A-7D rebuild
called the V-531.

Twin-engined Corsair proposed

A TWIN F404-engined version of the Corsair II has been proposed by Vought as a future US Navy light attack aircraft. The two General Electric engines would total over 50 per cent more thrust than the single 15,000lb Allison of the A-7E. Vought has already built more than 400 A-7Es, and the type is in service with 24 USN squadrons. Although the force has so far flown for more than 750,000hr, the manufacturer claims that a typical squadron aircraft has more than 17 years of service life left and could soldier on into the 1990s. The proposed V-529D version is almost identical to the A-7E except for the two F404 engines, new tailpipes and a wider rear fuselage to house them, and 20in fuselage stretch to keep the e.g. within limits. Both engines would be fed from the existing nose intake, a bifurcated duct splitting the incoming airflow between the two powerplants. Maximum rear fuselage width would be only 29in greater than at present. Empty weight would rise from 19,050lb (A-7E) to 19,952lb as a result, but the internal fuel load would rise from 10,036lb to 12,674lb. The F404 will power the Navy's F-18 fighter, so its use in a modified Corsair would provide useful commonality. Vought does not plan to build all new V-529Ds, suggesting to the US Navy that existing A-7Es be rebuilt. Unit cost of the modification would be less than $3 million, the company claims. Vought has teamed up with General Electric and Grumman. Given a prompt go-ahead by the Navy, the companies hope to start ground tests early next year. First flight would be scheduled for 1979.

Greetings All -

During the last visit to the Vought Archives, I copied a few drawings of the V-529 from the A-7X development.

Enjoy the Day! Mark

I've heard it claimed that the virtue of the twin-F404 A-7 variant at the time was that the engines were manufactured in district of the then Speaker of the House and in Ted Kennedy's home state, guaranteeing a fair measure of support on Congress. Sad to say, that's not too implausible.

The thought also occurs to me that a similar modification, but with afterburning F404s, would look interesting on a F-8.
 
Fun fact: in french "kardashian" sounds close from "coeur de chienne" which translates as "heart of a female dog" (b.i.t.c.h)

More seriously: I'm a die-hard fan of the SLUFF, starting with that funny nickname. It was a very remarquable bomb truck, and most importantly, its Crusader legacy gave it some "supersonic potential" as demonstrated by the A-7F. Since then I learned that the Air Force initial A-7 (before the TF41) was to have an afterburning TF30 - not to go supersonic but because the Navy A-7A lacked thrust.
 
Was a super sonic afterburner GE404 version considered like with the later A-7F Strikefighter wich was also to be re manufactured from ex USN A-7E or and ex USAF A-7D as faster eary 90s A-10 Alternative for use in european future cold war battlefields imagine Vought would have been interested even in the mid 70s to be able to offer a cheap alternative to the new A-10

I'm not aware of any such, but I'm sure someone will correct me if I'm wrong.

Thing is, the A-7 and the A-10 do different jobs. Keeping A-7s in service frees up A-10s to do the things they do best. A-7s go beyond the FLOT and hit rail yards and other marshalling points like FARPs. A-10s hang out over the FLOT and shoot up what gets past the A-7s.
