# Rescue and salvage ship

Rescue and salvage ships (hull classification symbol ARS) are a type of military salvage tug. They are tasked with coming to the aid of stricken vessels. Their general mission capabilities include combat salvage, lifting, towing, retraction of grounded vessels, off-ship firefighting, and crewed diving operations. They were common during World War II.
