The Navajo-class will provide ocean-going tug, salvage, and rescue capabilities to support fleet operations. The current capabilities are provided by three T-ATF 166 and two T-ARS 50 class ships, which reach the end of their expected service lives starting in 2020.
Navajo-class ships will be capable of towing U.S. Navy ships and will have 6,000 square feet of deck space for embarked systems. The platform will be 263 feet long, have a beam of 59 feet, and can carry a load of 1,796 tons.
In addition to T-ATS 6, Gulf Island Shipyard is under contract for the detail design and construction of the future USNS Cherokee Nation (T-ATS 7) and USNS Saginaw Ojibwe Anishinabek (T-ATS 8).
