The T-39 was developed by North American Aviation, Inc. as a private venture to meet a USAF requirement for a twin jet utility trainer. The prototype T-39 made its first flight on September 16, 1958. In January 1959, the USAF placed a production order and on June 30, 1960, the first production T-39A made its initial flight. In all, 143 T-39As and 6 T-39Bs were built for the USAF, another 62 T-39 variants were produced for the Navy. After the bulk of military contracts had been met, the Sabreliner entered the commercial market where it became a highly successful executive jet transport.

WR-ALC supported the communication and navigational systems in the T-39 during its USAF service. The "Sabreliner" on display was delivered to the USAF in February 1963 and assigned to the 2848th Air Base Wing at Norton AFB, CA. It later served with several units in Europe and was retired from the 1402nd Military Airlift Squadron at Maxwell AFB, AL in May 1985 and flown to the Museum for display.
