OVERVIEW: The Mk106 is a helicopter-towed combined magnetic and acoustic influence mine sweep system designed to detonate both magnetic- and acoustic-fuzed naval mines. It integrates the capabilities of the Mk104 and Mk105 systems in a single towed configuration to support multi-influence mine clearance.

DETAILS: The Mk106 was introduced the 1970s as a modular combination of the acoustic (Mk104) and magnetic (Mk105) influence sweeps, enabling simultaneous detonation of multiple mine types during a single sortie. Initially fielded with RH-53D Sea Stallion helicopters and later integrated into the MH-53E Sea Dragon’s airborne mine countermeasures suite, the Mk106 significantly reduced the time required for clearing complex minefields. The system includes a towed sled or components configured for dual-signal generation, simulating both magnetic fields and ship-like acoustic signatures. Its deployment allows broader area coverage and faster clearance timelines than using separate sweeps sequentially.

FUNCTION: Towed behind a helicopter, the Mk106 emits both magnetic and acoustic signatures to trigger respective naval mine fuzes. It is used to clear multi-threat maritime environments by inducing premature detonation of influence mines at a safe distance.
