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.

The thought also occurs to me that a similar modification, but with afterburning F404s, would look interesting on a F-8.
