action. Two years later the Soviet Union blockaded Berlin, Germany, and U.S. president Harry S. Truman ordered an airlift to resupply the city. The United States Air Force (USAF), realizing a need for training facilities, asked Welsh if any World War II airfields remained in inventory. He exhumed the Enid AAF folder, and the base was reactivated on August 1, 1948, as Enid Air Force Base. Cold War Reactivated as Enid Air Force Base, the installation became one of several pilot training bases within the Air Training Command (ATC). Its initial mission was to provide training for advanced students in multi-engine aircraft. On July 9, 1949, in keeping with the USAF tradition of naming bases for deceased flyers, the base was renamed for Lieutenant Colonel Leon Robert Vance Jr., USAAF, an Enid native who was awarded the Medal of Honor in World War II. The first aircraft flown at Vance when it was still Enid AAF was the BT-13A, followed shortly by the BT-15. In 1944, advanced students flew the TB-25 and TB-26. Following the establishment of the United States Air Force as a separate service in September 1947, Enid AFB-turned-Vance AFB began conducting training in the AT-6 Texan and eventually the T-33 Shooting Star. The T-37 Tweet first flew at Vance AFB beginning in 1961, and the T-38 Talon in 1963 as the USAF transitioned to its Undergraduate Pilot Training (UPT) system. Post Cold War In 1995 USAF officials announced that Vance would transition to the Specialized Undergraduate Pilot Training curriculum. Under SUPT, Vance students begin their training in the Beechcraft T-6 Texan II, followed by the T-1A Jayhawk for students identified for jet tanker, transport or large reconnaissance aircraft, and the T-38 Talon for fighter, bomber and other USAF fixed-wing aircraft. With the introduction of the Joint Primary Aircraft Training System (JPATS) to Vance in 2005, the 71 FTW began transitioning from the T-37 to the newer T-6 Texan II. Joint training with the United States Navy (USN) and United States Marine Corps (USMC) began at Vance in 1996, with select USN and USMC strike jet student naval aviators obtaining all training at Vance in the T-37 and T-38 except for carrier qualification, which they subsequently complete in the T-45 Goshawk at Naval Air Station Meridian, Mississippi or NAS Kingsville, Texas. A number of senior naval aviators in the rank of commander have also served as squadron commander
