A non-flying wing, the organization oversees the daily base operations and mission support functions of Nellis AFB such as personnel, finance, civil engineering, security and supply. The 99 ABW is the successor organization to the World War II 99th Bombardment Group. The group moved to Algeria in May 1943, where the group and its B-17 Flying Fortress aircraft distinguished themselves while flying bombing missions against targets in Italy, Sardinia and Sicily. Then, in December 1943, aircrews moved to Italy and conducted missions throughout Europe. Active for over 60 years, the 99th Strategic Reconnaissance Wing was a component organization of Strategic Air Command's deterrent force during the Cold War, as a strategic reconnaissance wing.
