Multiple independently targetable reentry vehicle

From Wacklepedia - The Free Encyclopedia

A multiple independently targetable re-entry vehicle, or MIRV, is one of a collection of nuclear weapons carried on a single intercontinental ballistic missile (ICBM) or a submarine launched ballistic missile (SLBM). Using MIRVs, a single launched missile can strike several targets, or fewer targets redundantly.
