An FMU-140/B fuze controls the opening of the dispenser at one of 10 predetermined altitudes between 90 m and 900 m using a doppler ranging radar or alternatively a 1.2 second time fuse.
The self-destruct time is set just prior to aircraft takeoff using a simple selector switch on the dispenser.
[1] Additionally, Conventional Munition Systems Inc. minefield clearing personnel reported dud GATOR mines detonating with no apparent triggering event, and speculated that the extreme heat of the Kuwait desert may have triggered detonation.
[1] The GATOR system provides a means to emplace minefields on the ground rapidly using high-speed tactical aircraft.
The minefields are used for area denial, diversion of moving ground forces, or to immobilize targets to supplement other direct attack weapons.
When a suitable target reaches the most vulnerable approach point it detonates the mine.
The mine weighs 1.95 kilograms and is 127 millimeters in diameter, with 580 grams of an RDX/Estane explosive mix.
