The only MARV system publicly known to be deployed at present is the Chevaline warhead developed by the British for their Polaris fleet. In addition to the MX warheads Milo alludes to, the Mk 600 maneuvering warhead for the Trident C-4 has been successfully tested. These MARVs all use aerodynamic control surfaces, and so they can maneuver only in the atmosphere during re-entry. Unfortunately, the current Soviet ABM system intercepts warheads outside the atmosphere, so it is unclear how much benefit comes from the added weight and reduced accuracy associated with the maneuvering mechanisms.
