The keel authentication, initially planned for 2020, was postponed due to the COVID-19 pandemic.

«This is a very special keel authentication ceremony for a multitude of reasons», said George Nungesser, Ingalls’ vice president of program management. «While we were able to work steadily and safely though the pandemic, visitation to the shipyard made commemorating major shipbuilding milestones a challenge. We are proud to be able to celebrate our talented shipbuilders and their successes today during this ceremonial keel laying».

Calhoun recently reached the halfway point of its construction. Ingalls is the builder-of-record for the Legend-class NSC program and has delivered nine national security cutters with two more under construction.

NSC-10 is named for Charles L. Calhoun, the first master chief petty officer of the Coast Guard. He served in the U.S. Navy for three years during World War II and was honorably discharged as a torpedoman second class in February 1946. Seven months later, he enlisted in the Coast Guard and held various leadership positions over the course of 14 years. He served as master chief petty officer of the Coast Guard from August 27, 1969 until August 1, 1973.

The sponsor of NSC-10 is Christina Calhoun Zubowicz, the granddaughter of Charles L. Calhoun.

«I want to thank the entire United States Coast Guard for this opportunity and recognize their fervent efforts in protecting America’s economic, national and border security», Zubowicz said. «May abundant divine protection, luck and blessings surround the ship: and the men and women – the shipbuilders, in crafting the new innovative national security cutter, Calhoun».

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. NSCs are 418 feet/127 m long with a top speed of 28 knots/32 mph/52 km/h, a range of 12,000 NM/13,809 miles/22,224 km, an endurance of 60 days and a crew of 120.

The 10th NSC

Huntington Ingalls Industries’ (HII) Ingalls Shipbuilding division officially started fabrication of the U.S. Coast Guard’s newest Legend-class National Security Cutter (NSC) USCGC Calhoun (WMSL-759) on November 12, 2019. The start of fabrication signifies that the first 100 tons of steel have been cut.

«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 February 21, 1946, as a Torpedoman Second Class. He enlisted in the Coast Guard on September 20, 1946, and over the course of 14 years held varying positions of leadership. He served as the MCPOCG from August 27, 1969 until August 1, 1973.

Ingalls has delivered eight Legend-class NSCs, two more are under construction and one additional is under contract. USCGC 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.
