Picture: Testing at the Kwajalein Atoll of the Peacekeeper re-entry vehicles, all eight fired from only one missile. With live warheads, each line would represent the explosive power of twenty-five Hiroshima-sized (Little Boy) weapons.
The LGM-118A Peacekeeper was a land-based ICBM deployed by the United States starting in 1986. Under the START II treaty, which never entered into force, the missile was to be removed from the U.S. nuclear arsenal in 2005, leaving the LGM-30 Minuteman as the only type of land-based ICBM in the U.S. arsenal. In spite of the demise of START II, the last of the LGM-118A "Peacekeeper" ICBMs were decommissioned on September 19, 2005.
The Peacekeeper was a MIRVed missile; each rocket could carry up to 10 re-entry vehicles armed with a 300-kiloton W87 warhead/MK-21 RVs (twenty-five times the power of the bomb dropped on Hiroshima during World War II).
