Remarks by Johan Visschedijk: "This aircraft was delivered to the US Army in November 1964, s/n 63-13128, and was assigned to 20th Aerial Surveillance Target Acquisition (ASTA) Detachment, Fort Riley, Kansas on 1 July 1965. The Detachment consisted of six Mohawks and two de Havilland Canada DHC-3 Otters, and were transferred to Nha Trang, South Vietnam on January 15, 1966, exactly a month later it was transferred to Hue Phu Bai. May 31, 1966, the 20th STA Detachment was redesignated 131st Aviation Company. In 1969 the Mohawk 63-13128 was damaged by ground fire and was returned to Grumman in the USA for repairs.
By June 1972 the aircraft had been transferred to the USN under the out-of-sequence BuNo. 313128 and attached to the Navy Test Pilot School at NAS Patuxent River, Maryland. In December 1976 it was struck off charge with the USN and relocated to the MASDC at Davis-Monthan AFB, Arizona.
On July 28, 1977, it was recovered and registered N87864 it was acquired by the Pittsburgh Institute of Aeronautics (PIA), West Mifflin, Pennsylvania, it was registered as N87864. For seven years it was used as a ground instructional airframe in several aircraft maintenance and avionics courses. In the early eighties six Westinghouse J34 jet engines were obtained by PIA, to operate the jet engines the Mohawk was chosen as an engine test stand and fitted with two jet engines under the wing next to the original two Lycoming T53 turboprops. In May 1985 the conversion was ready and this Mohawk became the only four-engined aircraft of the type with all engines operational, although the aircraft never left the ground in this configuration.
On December 8, 1997, the Mohawk was sold, without the jet engines, to Transupport, Inc., Merrimack, New Hampshire. It was loaned to the America Wings Air Museum, Anoka County, Minnesota, in June 2003 and registered N2036P. Fifteen years later the aircraft was acquired by the Military Aviation Preservation Society and it arrived at the MAPS Air Museum at Akron-Canton Airport, North Canton, Ohio, on November 16, 2018.
