garys said:I just read the brief description of this twin engine design in the book U.S. Naval Fighters 1922 to 1980s by Lloyd S. Jones. In it, he describes that the designation was originally given in 1943 to a twin piston engine fighter design similar, and possibly in competition with, the F7F. When the Navy lost interest in this configuration in 1945, the designation was "transferred" to a new jet fighter (the Pirate). The V-358 designation and pictures seem to indicate a different, later, design (c.1947 perhaps?), especially the tip tanks. So, to get back to the original question, has anyone ever seen any ilustration of the earlier F6U, possibly V-340? Thanks!
