HII’s Newport News Shipbuilding division has completed post-shakedown availability (PSA) work on Virginia-class fast attack submarine USS New Jersey (SSN 796).

The PSA, a maintenance period that typically follows delivery of new ships, included combat systems and electronics upgrades, as well as general maintenance on the submarine. The submarine was redelivered to the US Navy on April 3, 2026.

“Maintaining our nation’s undersea maritime supremacy is strengthened by the redelivery of USS New Jersey,” said Jason Ward, NNS vice president of new construction submarine programs.

“Our combined NNS-Navy team is focused on the mission and understands the importance of getting this submarine to the fleet.”

The US Navy commissioned USS Jersey in a traditional ceremony held at Naval Weapons Station Earle in Middletown, New Jersey, in September 2024.

The submarine is 377 feet (115 meters) long, has a 34-foot (10-meter) beam and is able to dive to depths greater than 800 feet (243 meters) and operate at speeds in excess of 25 knots. New Jersey has a crew of nearly 135 navy personnel.

Fast-attack submarines are multi-mission platforms enabling five of the six navy maritime strategy capabilities – sea control, power projection, forward presence, maritime security, and deterrence.

They are designed to excel in anti-submarine warfare, anti-ship warfare, strike warfare, special operations, intelligence, surveillance and reconnaissance, irregular warfare, and mine warfare.
