USNS Mohawk (T-ATF-170) was a United States Navy Powhatan-class tugboat operated by the Military Sealift Command from 1980 to 2005.

[4] Her unrefueled range at 13 knots was 10,000 miles (16,000 km)[2] Mohawk's aft deck was largely open to accommodate a number of different roles.

[4] The towing system could accommodate either wire rope or synthetic-fiber hawsers and produce as much as 90 short tons of bollard pull.

In February 1982 Mohawk was used as a dive platform to investigate the crash of an F-4E Phantom II in shallow water 30 miles southeast of Charleston, South Carolina.

[10] During the Fall of 1985 and the winter of 1985-1986 Mohawk was deployed to the Caribbean to track and report on suspicious vessels as part of the war on drugs.

[12][13] On 15 December 1987 the Kuwaiti oil tanker Qarouh collided with the Panamanian freighter Explorer about 700 miles off the coast of Florida.

Mohawk was the first vessel on the scene of the accident and took all 29 members of the tanker's crew aboard since Qarouh appeared to be sinking.

[14] On 28 January 1989, Mohawk worked with USNS Grasp to pull the grounded USS Spruance off a coral reef near Andros Island, in the Bahamas.

[15] Public tours of Mohawk were offered on 24–25 March 1990 at the Port Canaveral Seafood Festival,[16] on 19 May 1991 at the Washington Navy Yard,[17] and in October 1992 as part of the Wilmington, North Carolina Riverfest.

Mohawk towed Empress II, which generated high-power microwave pulses, in order to test the electronic hardening of the British ship.

The wreck was leaking fuel which threatened the world's second largest coral reef system and blocked a harbor mouth on the Honduran island Roatan.

[21] In February 1995, Mohawk recovered the wreckage of a T-34C Turbo Mentor that crashed in the Gulf of Mexico off Corpus Christi.

[25] On 10 October 1999 Mohawk took ex-Guadalcanal in tow at the Naval Inactive Ship Facility in Philadelphia with the intent to move her to Hampton Roads, Virginia.

[28] During June 2004, Mohawk towed ex-Leahy from the Panama Canal to the Naval Inactive Shipp Maintenance Facility in Beaumont, Texas.

[29] Mohawk was regularly deployed to the Mediterranean to support Sixth Fleet operations as a towing, diving, and salvage asset.

[31] Mohawk was taken out of service on 16 August 2005 and placed in reserve in the Naval Inactive Ship Maintenance Facility at Philadelphia, Pennsylvania.
