The 815th Troop carrier Squadron was activated at Ashiya, Japan on January 1, 1953; this time equipped with the C-119 "Flying Boxcar", a twin-engine; twin boom medium transport. The famous red "Flying Jennie" was adopted as the squadron mascot at this time. The next few years were spent shuttling personnel and cargo throughout Asia - initially in support of the Korean war and later supporting other cold war and humanitarian activities. Operations in support of the Korean war involved an historic 1953 movement of a full army division from japan to Korea, all in a two-week period, and other front line operations that were frequently hazardous. In 1955, the 815th staged the first Troop Carrier mobility exercise in history - two weeks operating from an unprepared airstrip at Futema, Okinawa.
In 1958, the 815th traded in its aging C-119s for the then state of the art C-130A Hercules.
