93rd Civil Engineering Squadron

The 93rd Civil Engineering Squadron (CES) was an integral support unit assigned to the 93rd Bombardment Wing at Castle Air Force Base, California. Activated during the height of the Cold War, the squadron provided critical engineering, construction, and base maintenance services to ensure the operational readiness of the wing’s B-52 Stratofortress bombers. The 93rd CES played a vital role in infrastructure development, emergency response, and rapid runway repair, directly supporting nuclear deterrence and strategic air operations. Following the end of the Cold War and the subsequent drawdown of forces, the squadron was inactivated in the 1990s alongside the closure of Castle AFB.
