Salvage and rescue 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 manned diving operations. They were common during World War II.

The following ship classes have been designated under the ARS hull classification symbol in United States Navy Service.

The earliest designated United States Navy salvage ships (ARS) were converted Lapwing-class minesweepers. Ships of this type were operated by the United States Navy as salvage ships from June 1941 until USS Viking was decommissioned and scrapped in 1953.

The United States Navy operated Diver-class rescue and salvage ships (ARS) from October 1943 until the last example was decommissioned in July 1979. Several ships of this class were converted to other uses, and USS Shackle remained in service as the 213' United States Coast Guard Cutter USCGC Acushnet until March 2011.

Several ships were converted and redesignated as salvage ships (ARS) during World War II.

The United States Navy operated Anchor-class rescue and salvage ships (ARS) from October 1943 until March 1946.

The United States Navy operated Weight-class rescue and salvage ships (ARS) from August 1943 until the last example was decommissioned in June 1946. The Weight-class ships were originally intended for delivery to the Royal Navy under different names, as part of the Lend-Lease program. However, they were instead delivered to and operated by the United States Navy.
