One of the Navy’s most “technologically advanced and lethal” ships will call Pascagoula, Miss., home for the next two years as Ingalls Shipbuilding modernizes the stealth-capable ship with upgrades including the installation of hypersonic missile tubes.

The shipyard welcomed the USS Zumwalt (DDG 1000) on Aug. 19 upon its arrival from its homeport of San Diego, Calif.

“It is an honor to serve the sailors of Zumwalt and to welcome them to our community,” said Ingalls’ DDG 1000 ship construction manager Bruce Knowles. “The Ingalls team is ready to support you in completing this important work.”

Ingalls was awarded a $154.8 million contract modification from the Navy to begin the upgrades after initially being given a $10.5 million contract in January to begin the planning phase.

USS Zumwalt is the lead ship in its class and has stealth capabilities, with a radar cross-section similar to a fishing boat despite being a 600-foot long, 16,000-ton guided missile destroyer. She was built by Bath Iron Works in Maine, christened in April 2014, and commissioned into the Navy in October 2016.

DDG 1000 is named for Adm. Elmo Zumwalt Jr., who served as Commander of Naval Forces Vietnam during the Vietnam War and then as the 19th Chief of Naval Operations. At 49 years of age, he was the youngest person elevated to the Navy’s top post.

The hypersonic tubes which will be installed on the Zumwalt will each old three Common Hypersonic Glide Bodies (C-HGB), which are being developed jointly between the Navy and the U.S. Army, according to the U.S. Naval Institute.

“The upgrades will ensure Zumwalt remains one of the most technologically advanced and lethal ships in the U.S. Navy,” the Navy said in a statement to USNI.

USS Michael Monsoor (DDG 1001) is also slated for the same weapons system upgrades at Ingalls, while a third ship in the Zumwalt class, Lyndon B. Johnson (DDG 1002), is already at the Pascagoula shipyard, having arrived in January of last year for combat systems activation.
