T-ATF - Powhatan Class Fl
Function: Seven ocean-going tugs are operated by Military Sealift Command and provide the U.S. Navy with towing service, and when augmented by Navy divers, assist in the recovery of downed aircraft and ships.
History: Fleet tugs are used to tow ships, barges and targets for gunnery exercises. They are also used as platforms for salvage and diving work, as participants in naval exercises, to conduct search and rescue missions, to aid in the clean up of oil spills and ocean accidents, and to provide fire fighting assistance. USNS Apache (T-ATF 172) is the last of the Powhatan class of ocean tugs delivered to the Navy in 1981.
Description: Each vessel is equipped with 10 ton capacity crane and a bollard pull of at least 54 tons. A deck grid is fitted aft which contains 1 inch bolt receptacles spaced 24 inches apart. This allows for the bolting down of a wide variety of portable equipment. There are two GPH fire pumps supplying three fire monitors with up to 2,200 gallons of foam per minute. A deep module can be embarked to support naval salvage teams.

ARS - Safeguard Class Res
Function: Rescue and salvage ships render assistance to disabled ships, provide towing, salvage, diving, firefighting and heavy lift capabilities.
History: Fleet tugs are used to tow ships, barges and targets for gunnery exercises. They are also used as platforms for salvage and diving work, as participants in naval exercises, to conduct search and rescue missions, to aid in the clean up of oil spills and ocean accidents, and to provide fire fighting assistance. USNS Apache (T-ATF 172) is the last of the Powhatan class of ocean tugs delivered to the Navy in 1981.
Description: The mission of the rescue and salvage ships is four-fold: to debeach stranded vessels, heavy lift capability from ocean depths, towing of other vessels, and manned diving operations. For rescue missions, these ships are equipped with fire monitors forward and amidships which can deliver either firefighting foam or sea water. The salvage holds of these ships are outfitted with portable equipment to provide assistance to other vessels in dewatering, patching, supply of electrical power and other essential service required to return a disabled ship to an operating condition. The U.S. Navy has responsibility for salvaging U.S. government-owned ships and, when it is in the best interests of the United States, privately-owned vessels as well. The rugged construction of these steel-hulled ships, combined with speed and endurance, make these rescue and salvage ships well-suited for rescue/salvage operations of Navy and commercial shipping throughout the world. The versatility of this class of ship adds immeasurably to the capabilities of the U.S. Navy with regard to rendering assistance to those in peril on the high seas.
