"Each new ship in this class has been an exciting opportunity to build on our legacy," said Jay Boyd, Ingalls' NSC program manager. "This is the 10th cutter in the class and a steady production line has allowed our shipbuilders to continually improve on how we build and deliver these technologically advanced cutters to the nation."
NSC 10 is named for Master Chief Petty Officer Charles L. Calhoun, who was the first Master Chief Petty Officer of the U.S. Coast Guard (MCPOCG). He served in the U.S. Navy for three years during World War II and was honorably discharged on Feb. 21, 1946, as a Torpedoman Second Class. He enlisted in the Coast Guard on Sept. 20, 1946, and over the course of 14 years held varying positions of leadership. He served as the MCPOCG from Aug. 27, 1969 until Aug. 1, 1973.
Ingalls has delivered eight Legend-class NSCs, two more are under construction and one additional is under contract. Stone (WMSL 758), the ninth NSC, is scheduled for delivery in 2020.
NSCs are capable of meeting all maritime security mission needs required of the high-endurance cutter. They include an aft launch and recovery area for two rigid hull inflatable boats and a flight deck to accommodate a range of manned and unmanned rotary wing aircraft. The Legend class is the largest and most technologically advanced class of cutter in the Coast Guard, with robust capabilities for maritime homeland security, law enforcement, marine safety, environmental protection and national defense missions. NSCs play an important role enhancing the Coast Guard’s operational readiness, capacity and effectiveness at a time when the demand for their services has never been greater.
The Legend-class cutter, also known as the National Security Cutter (NSC) and Maritime Security Cutter, Large, is the largest active patrol cutter class of the United States Coast Guard. Entering into service in 2008, the Legend class is the largest of several new cutter designs developed as part of the Integrated Deepwater System Program.
Legend-class cutters have increased data link bandwidth.[citation needed] The Hensoldt (formerly EADS North America) TRS-3D radar system provides three-dimensional air and surface search functions and is used in the LCS program as well as the German Korvette 130 program. The cutters are also equipped with the AN/SLQ-32(V)2 Electronic Warfare (EW) system used in the DDG-51 class. The cutters AN/SLQ-32B(V)2 system is to be upgraded under the Surface Electronic Warfare Improvement Program (SEWIP).
The Legend class is equipped with the same 220 rpm Bofors 57 mm gun as mounted on the USN's Littoral combat ships. Guided 57 mm ammunition is being developed for the Mk 110 for the Navy and Coast Guard, including for use on the National Security cutters. The Missile Defense duties are handled by the MK 53 NULKA decoy systems, the MK 36 SRBOC countermeasure systems also used on the FFG-7 and CG-47 programs and the Phalanx CIWS.
