OVERVIEW: The Maham‑2 is an Iranian air- or helicopter-deployable bottom mine equipped with sonic and magnetic influence fuzes. It is designed for coastal and littoral warfare to detect and neutralize surface vessels and submarines.

DETAILS: The mine, reportedly weighing 480 kg with a diameter of 0.46 m, contains approximately 350 kg of explosives and is equipped with both magnetic and acoustic sensors. It is laid by IRGC naval helicopters, including Mi‑17 platforms, at depths between 10 m and 50 m. The dual-fuze system enables it to target vessels up to 250 tons moving at 4–15 knots. Reports indicate operational use from 2023 by the IRGC Navy in exercises and deployment drills along Iran’s southern coastline.

FUNCTION: After deployment, the Maham‑2 rests on the seabed and remains dormant until sensing both a magnetic field disturbance and vessel-generated acoustic noise within its detection criteria. Upon confirming a valid target, the mine detonates its charge to damage or sink ships or submarines.

NOTE:
IOC: 2023 (first reported deployment)
