Limpet mines: Sticky weapons deployed against Indian-crewed vessel in Gulf

Limpet mines are magnetic or adhesive devices designed to attach to the hulls of ships, making them a favored tool for maritime sabotage and attacks. Named after the limpet sea creature that clings to rocks, these weapons can be placed quickly by trained personnel including swimmers, divers, or military frogmen, requiring no complex deployment infrastructure.

The mines function by adhering to a vessel's exterior through either magnetic properties or suction cups, allowing attackers to strike without boarding the target ship or using conventional naval weaponry. Once attached, they can be detonated remotely or on a timer, causing damage to the hull and potentially disabling critical systems.

The recent incident involving an Indian-crewed vessel in the strategically vital Strait of Hormuz marks the latest in a series of maritime security incidents in the region. The attack highlighted vulnerabilities facing commercial shipping in one of the world's most important waterways, through which approximately one-third of global seaborne petroleum passes.

Limpet mine attacks have been employed historically by military forces and irregular actors in maritime conflicts. Their effectiveness lies in their simplicity, ease of deployment, and the difficulty in detecting trained personnel placing them in congested shipping lanes or territorial waters.
