300 kt MARV
I know what MIRV means. What is/are MARV?
MARV is the acronym for Maneuvering Reentry Vehicle (see below for an explanation).
MARV
The maneuvering reentry vehicle (MARV) is one of the latest developments in nuclear weapons delivery systems. MARVs are designed either to deliver a nuclear warhead with pinpoint accuracy, or to enable the warhead to avoid enemy detection and destruction through evasive maneuvers.
MARVs are expected to have an accuracy of 36.6 m (120 ft) after a flight of 1,609 km (1,000 mi). MARVs designed for evasive maneuvers employ such techniques as small steering rockets, internal weight shifting, and movable flaps or fins.
