The maneuverable reentry vehicle (abbreviated MARV or MaRV) is a type of
warhead
A warhead is the forward section of a device that contains the explosive agent or toxic (biological, chemical, or nuclear) material that is delivered by a missile, rocket, torpedo, or bomb.

for
ballistic missiles that is capable of maneuvring and changing its trajectory.
MaRV can be capable of autonomously tracking ground targets to make sure the missile does not miss the target, because of the frequent trajectory shifts. This often requires some terminal active homing guidance (like Pershing II
active radar homing).

The Advanced Maneuverable Reentry Vehicle (AMaRV) was a prototype MARV built by
McDonnell Douglas
McDonnell Douglas was a major American aerospace manufacturing corporation and defense contractor, formed by the merger of McDonnell Aircraft and the Douglas Aircraft Company in 1967. Between then and its own merger with Boeing in 1997, it pro ...
. Four AMaRVs were made and represented a significant leap in
reentry vehicle sophistication. Three of the AMaRVs were launched by
Minuteman-1 ICBMs on 20 December 1979, 8 October 1980 and 4 October 1981. AMaRV had an entry mass of approximately 470 kg, a nose radius of 2.34 cm, a forward frustum half-angle of 10.4°, an inter-frustum radius of 14.6 cm, aft frustum half angle of 6°, and an axial length of 2.079 meters. No accurate diagram or picture of AMaRV has ever appeared in the open literature. However, a schematic sketch of an AMaRV-like vehicle along with trajectory plots showing hairpin turns has been published.
AMaRV's attitude was controlled through a split body flap (also called a "split-windward flap") along with two yaw flaps mounted on the vehicle's sides.
Hydraulic actuation was used for controlling the flaps. AMaRV was guided by a fully autonomous navigation system designed for evading
anti-ballistic missile (ABM) interception.
