OVERVIEW: The Mk62 Quickstrike is a 500 lb air-delivered bottom influence mine converted from the Mk82 bomb, designed to target and destroy surface vessels and submarines operating in shallow coastal waters. It uses magnetic and seismic fuzes for selective engagement based on vessel signatures.

DETAILS: Entering service in 1982, the Mk62 mine is built from the Mk82 general-purpose bomb and fitted with the Mk57 Target Detection Device (TDD), which provides magnetic and seismic sensing capabilities. The system includes programmable features such as arming delay, ship count settings, self-sterilization, and self-destruct timers, allowing safe and flexible deployment. Its smaller size compared to other Quickstrike variants enables delivery from a wider range of tactical aircraft. Parachute-retarded delivery ensures stable descent and proper positioning on the seabed. The mine offers a rapid and cost-effective mining option for denying access to strategic maritime areas.

FUNCTION: After being released from an aircraft, the Mk62 descends to the seabed and arms after a preset delay. It passively monitors for magnetic and seismic signatures from surface vessels or submarines, detonating only when a qualifying target is detected.
