A Multiple Reentry vehicle payload for a ballistic missile
deploys multiple warheads in a pattern against a single target. (As opposed to MIRV, which deploys multiple warheads against multiple targets.) The advantage of an MRV over a single warhead is that the damage produced in the center of the pattern is far greater than the damage possible from any single warhead in the MRV cluster, this makes for an efficient area attack weapon. Also, the sheer number of Warheads make interception by Anti-ballistic missile
s unlikely.
Improved warhead designs allow smaller warheads for a given yield, while better electronics and guidance systems allowed greater accuracy. As a result MIRV technology has proven more attractive than MRV for advanced nations. Because of the larger amount of nuclear material consumed by MRVs and MIRVs, single warhead missiles are more attractive for nations with less advanced technology. The United States deployed an MRV payload on the Polaris A-3. The Soviet Union deployed MRVs on the SS-9 Mod 4 ICBM. Refer to atmospheric reentry

Ballistic missile
A ballistic missile is a missile that follows a sub-orbital ballistic flightpath with the objective of delivering one or more warheads to a predetermined target. The missile is only guided during the relatively brief initial powered phase of flight and its course is subsequently governed by the...

Anti-ballistic missile
An anti-ballistic missile is a missile designed to counter ballistic missiles .A ballistic missile is used to deliver nuclear, chemical, biological or conventional warheads in a ballistic flight trajectory. The term "anti-ballistic missile" describes any antimissile system designed to counter...
