On March 4, 2017, the US Coast Guard named the seventh new National Security Patrol Boat (NSCs) Kimball (WMSL 756). The naming ceremony was held at the shipyard of Huntington Ingalls Industries (HII), Mississippi.
According to HII, the Kimball National Security Patrol Boat is the third ship named after Sumner I. Kimball. The first Kimball (WSC/WMEC-143) national security patrol boat was commissioned in 1927 and retired in 1968. The second name was SS Sumner I. Kimball (EC2-S-C1); it was sunk by the Nazi submarine U-960 tortoise, killing 64 Americans.
According to GE Marine Solutions, all new Legend-class national safety patrol boats will be equipped with a fuel-fired combined power plant (CODAG) propulsion system consisting of a GE LM2500 gas turbine and two diesel engines.
The LM2500 gas turbines for the Legend-class national safety patrol boats are manufactured at GE's Avondale, Ohio facility. The world's 500 warships in 35 countries, including patrol boats, destroyers and cruisers, as well as light cruisers, frigates, amphibious ships and aircraft carriers, have used more than 1,400 GE gas turbines, with a cumulative operating time of more than 14 million hours.
