Defense Systems Evaluation Squadron
4758th Defense Systems Evaluation Squadron started life at
Biggs Army Airfield in 1939 as the 129th Observation Squadron
equipped with a single B-10. The designation was changed
to the 6th Tow Target Squadron and then again to the 406th
Base Unit. In December, 1944 the unit moved to Deming
AAF, NM. In September of 1945 the unit returned to Biggs
and was redesignated the 27th Tow Target Squadron. Late
1947 brought another name change; the 1st Tow Target
Squadron. The unit was deactivated from October 1949
through May, 1950. In 1960 the designation changed to
the 1st Aerial Tracking Squadron and in 1962 the final
designation of the 4758th Defense Systems Evaluation Squadron
came into being. When Biggs AFB closed in 1966 the
4758th moved to Holloman AFB, NM where it remained until
merging with the 4677th DSES in late 1970.
During the war years much of the unit's duties were carried
out by Women Airforce Service Pilots (WASP). Women
pilots ferried many of the aircraft delivered to the armed
forces during WW II. They also served in many of the
support functions such as target towing and observation
work. This is a history that is often overlooked.
