Insignia of the U.S. Navy Attack squadron 42 (VA-42) "Green Pawns". The insignia for VA-42, the green pawn, was  originally  approved  by the U.S. Navy Chief of Naval Operations (CNO) for Bombing and Fighting Squadron 75  (VBF-75) on 28 October 1946. When a new Fighting Squadron 42 (VF-42) was established on 1 September 1950 they adopted the
green pawn insignia that had been used by the former VF-42. In 1953, the insignia was carried over to VA-42 following its redesignation from VF-42.
