400th Missile Squadron

The 400th Missile Squadron was a strategic missile unit of the United States Air Force stationed at Francis E. Warren Air Force Base in Wyoming. It operated intercontinental ballistic missiles as part of the nation's nuclear deterrence system.

The unit was founded in 1942 as a reconnaissance squadron and served as a bombardment squadron during World War II. It converted to missile operations in 1964 to support Cold War strategic defense efforts.

The squadron personnel maintained high technical standards through specialized training programs focused on missile operations and strategic defense protocols.

The base is accessible by appointment with proper security clearances. Visitors should check current access requirements in advance and register with the appropriate authorities.

In 1986 the squadron became the sole operational Air Force unit equipped with LGM-118A Peacekeeper missiles carrying multiple reentry vehicles. This exclusive status made it a critical element of American nuclear deterrence strategy.
