was built as a A-4F, then converted to a prototype A-4M the same year, and
immediately instrumented for A-4M development flight test and structural
demonstration requirements. After conversion, its first flight was on 14 May
1970.

This A-4M aircraft commenced flight testing at Patuxent River in February
1971 as the Board of Inspection and Survey (BIS) Trials aircraft. Flight testing
continued until its retirement to Patuxent River Naval
Air Museum in November 1990. Over the years, this particular aircraft was
involved in many tests and evaluations. Primarily, it was instrumented and
utilized as the test aircraft for the Pratt & Whitney J-52-P-408 turbojet engine
Component Improvement Program.
