The Mk 60 CAPTOR is the US Navy's only deep water mine. The MK-60 CAPTOR, one of the Navy's primary anti submarine
weapons, is actually a deepwater moored torpedo launcher. Mine Mk 60 is a sophisticated anti-submarine warfare (ASW) moored
mine which is designed to detect and classify submarines and release a modified Torpedo Mk 46 to acquire and attack submerged
targets only. This deep water mine is designed to be laid by aircraft or submarine, and is anchored to the ocean floor. The mine utilizes
an influence firing device and is able to classify passing submarines. Its acoustic detection system is designed to seek hostile
submarines, ignoring surface craft and friendly submarine acoustic signatures. The weapon lies dormant until a target is detected, at
which time the torpedo swims out of its capsule to attack and destroy its target. As in other mines, the Mk 60 incorporates an
arming-delay. The MK-60 can be deployed by air, submarine, or surface ship.

This weapon was developed by the Mine Division of the Naval Ordnance Laboratory, which is now located at the Naval Surface
Warfare Center Dahlgren Division, Coastal Systems Station, Panama City, Florida. Because it can be converted to have some
operational capability in littoral waters, a modification to CAPTOR is being considered as one of the options for the Littoral Sea Mine
(LSM) program.
