It then served with the 5th Liaison Squadron at the same location between 08-Sep-1952 and 02-Mar-1953 before returning to the 314th TCM Wing until returning to Donaldson AFB., Greenville, SC., but now with the 7th Liaison Squadron. This allocation only lasted until 26-Jun-1953 as it was now assigned to the Military Transport Command (the forerunner of MATS) at Andrews AFB where it was attached to the 1401st Air Base Wing until 22-Oct-1953 after which was re assigned to the TAC for 5 months back with the 7th Liaison Squadron until 30-Mar-1954.

The next event was an assignment to the Air Defence Command which lasted for over five years. First location was at Minneapolis – St Paul, MN., with the 514th Air Defence Group between 30-Mar-1954 and 05-Apr-1954. Several weeks with the 515th Air Defence Group at Duluth, MN., followed until 24-Jun-1954 and then by a return to Minneapolis – St Paul 14-Jul-1954 with the 514th and then once again to Duluth with the 515th until 01-Jul-1955.

There followed a return to its birthplace at Downsview, Toronto, ON., for a period of maintenance that lasted until 22-Dec-1955 and then back to active duty back at Duluth now with the 343rd Fighter Group, part of the Central Air Defence Command and then with the 343rd Consolidated Aircraft Maintenance Squadron where it remaining until 20-Oct-1959. The next allocation was to the 30th Air Division and a deployment to Sioux Lookout, Ontario, Canada where it was active with the 915th Air Command and Warning Squadron in. There was a return to Duluth and the 343rd Consolidated Aircraft Maintenance Squadron which took its record on to 17-Jul-1961.

The next assignment was with the Systems Command at Wright Patterson AFB., OH., between 17-Jul & 01-Sep-1961 until 01-Sep-1961. The acronym on the record card shows as AOD DV and currently the meaning is not understood.
