The National Museum of Nuclear Science and History at Kirtland AFB, New Mexico, received a deactivated LGM-118 Peacekeeper intercontinental ballistic missile for display on 22 April 2011. Delivered by a C-5 crew from the 445th Airlift Wing, the Air Force Reserve Command unit at Wright-Patterson AFB, Ohio, the seventy-one foot tall, 195,000 pound, four-stage Peacekeeper arrived in sections and was immediately put on display. The ten-warhead Peacekeeper was the US's most accurate and powerful ICBM from 1986 until it was decommissioned in 2005. Fifty of the missiles were fielded. Some of the decommissioned ICBMs have since been used to launch satellites. The HTV-2 hypersonic research vehicle, developed by Lockheed Martin’s Skunk Works, is also launched by a modified Peacekeeper.
