52-6122 was made available on 13-May-1953 and accepted on 20-May-1953 by the 6600th Air Depot AMO (Air Material Overseas Unit), at Downsview, ON., after which it was delivered to the Tactical Air Command at George AFB., CA., where it was attached to the 1st Liaison Squadron from 27-May-1953 until 30-Jan-1954. It was next assigned to the Air Material Command and went to the San Bernardino Air Depot at Norton AFB., CA., in preparation for a move north.
It was re assigned to the Northeast Air Command and moved to Goose Bay AFB., in Newfoundland where it was attached to the 6615th Test Squadron between 09-Jun-1954 and 01-Sep-1954. Staying in Newfoundland it now moved to Ernest Harmon AFB., where it joined the 6605th Air Base Wing and when the NEA was re designated as the Strategic Air Command the unit was also re designated as the 4801st Air Base Group with whom it remained until 11-Jun-1958 but with a visit to Downsview between 26-Jun-1957 and 22-Aug-1957.
Its next allocation was to Goose Bay with the 22nd Helicopter Squadron until 10-Sep-1958 after which it returned to Ernest Harmon, initially with the 4801st Air Base Wing and then with the 4801st Combat Support Group until 29-Apr-1960.
A re-assignment to the Tactical Air Command saw it move south to Langley AFB., VI where it was attached to the 4440th Air Defence Group. This was only for a few days as it soon went to the Air Defence Command and the 32nd Fighter Group at Minot AFB., ND., from 10-May-1960, which was later re-designated the 32nd Fighter Wing (Air Defence). It stayed at Minot as it was re-assigned to the Strategic Air Command and joined the 4136th Strategic Wing from 30-Jun-1962.
The record card shows the aircraft as being attached to the 555th Strategic Wing, however we have been unable to clarify its location.
However the next allocation is shown as the 4510th Combat Crew Training Wing at Luke Air Force Base from 17-Feb-1965 before passing to the Fairchild Aircraft Facility at St. Augustine, Maryland.
It is next shown as being transferred to the 56th ACW at Nakhon Phanom AFB, Thailand on 31-May-1967. But that is where our record of its military history ends but it seems to have been passed to the US Army but we have no record of such activity.
It was struck off charge from the USAF inventory on 20-Jun-1967 moving to the US Army.
