Documents signed Monday mark the official transfer of custody of the ship from HII to the Coast Guard. Stone is scheduled to sail away from the shipyard at the end of this year to its homeport in Charleston, South Carolina.

We could not be prouder to deliver our ninth national security cutter to the Coast Guard,” Ingalls Shipbuilding President Brian Cuccias said. “Ending the year with this significant achievement is a true testament to the perseverance of our shipbuilders. Stone is a powerful ship that will have great opportunities to demonstrate the value of its multi-mission capabilities for many years to come.”

NSC 9 is named to honor Coast Guard Commander Elmer “Archie” Fowler Stone, Coast Guard aviator number one, who made history in 1919 for being one of two Coast Guard pilots in the four man air crew who completed the first trans-Atlantic flight in a Navy seaplane.

The Legend-class NSC is the most technologically advanced ship in the Coast Guard’s fleet, which enables it to meet the high demands required for maritime and homeland security, law enforcement, marine safety, environmental protection and national defense missions.

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. NSCs are 418 feet long with a top speed of 28 knots, a range of 12,000 miles, an endurance of 60 days and a crew of 120.

The Legend-class is equipped with the same Bofors 57 mm naval 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.[32] The combination of the Mk 110 and the Phalanx gives the cutters anti-surface capability, limited air-defense capability, and the capability to provide naval gunfire support.
