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 1401^st Air Base Wing until 22-Oct-1953 after which was re assigned to the TAC for 5 months back with the 7^th 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 514^th Air Defence Group between 30-Mar-1954 and 05-Apr-1954. Several weeks with the 515^th 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 514^th and then once again to Duluth with the 515^th until 01-Jul-1955.
