Mk 40 Destructor bottom mine

The Destructor series of U.S. Navy aircraft-laid bottom mines began as conversions of Mk 80 series bombs during the Vietnam War. The conversion included the installation of a modular arming kit containing an arming device, explosive booster and magnetic-influence firing device.

The Mk 40 was a modified Mk 83 1,000-lb (454-kg) bomb. It could cause greater damage to land targets than could the Mk 36. It could be laid to a depth of 299 ft (91 m).

No longer in service.
