Douglas B-66 Destroyer

While the U.S. Navy was working on the A3D Skywarrior, the U.S. Air Force expressed interest in a land-based version.  The resulting B-66 Destroyer, although visually similar, had few interchangeable components.  The prototype first flew in 1954.

Like the naval version, the USAF used the B-66 in secondary roles such as reconnaissance, electronic warfare and weather reconnaissance.
