Submarine Escape and Rescue (SMER)

Submarine Escape and Rescue (SMER) involves procedures and equipment that allow submariners to escape from a submerged vessel during an emergency. When a submarine is underwater and cannot surface normally, trained personnel can use specialized escape systems—such as escape trunks or capsules—to exit safely. Once outside, rescue vessels or teams can retrieve the escaping crew. SMER is critical for saving lives during accidents, ensuring submariners have the means to evacuate quickly and safely until they can be brought to the surface. It combines training, equipment, and coordinated rescue efforts for effective underwater emergency response.
