PNSY Undocks USS North Dakota (SSN 784)

PORTSMOUTH NAVAL SHIPYARD, Maine – Virginia-class attack submarine USS North Dakota (SSN 784) was safely undocked Feb. 26, marking a significant milestone in its maintenance and modernization availability. North Dakota has undergone repairs, structural inspections, and replacements of mechanical and electrical systems. This extensive work enhances the submarine’s capabilities, modernizes critical systems and equips Sailors — the engine that powers the fleet — with the most advanced undersea platform possible ready to meet operational demands.

“The execution of submarine maintenance with excellence is fundamental to ensuring our fleet stands as the world’s premier warfighting force – ready, capable, and unmatched,” said Capt. Jesse Nice, shipyard commander. “North Dakota’s successful undocking represents the coordinated effort across the shipyard to return a combat-ready asset back to the fleet. We can only achieve this level of success by maintaining a committed focus on personnel safety and supporting innovation and authority driven by the experts closest to the work.”

The undocking milestone reflects the expertise and commitment of the project team, workforce and Sailors who have worked tirelessly to advance North Dakota through its availability. As a part of the total force, their collaboration, disciplined execution, and dedication sustain the shipyard’s mission and directly support fleet readiness.

“This [undocking] sets the tone for our final mission here at PNSY — get back in the fight and support the fleet,” said Cmdr. Trey Kennard, North Dakota commanding officer. “The incredible dedication and coordination between the crew and project team set us on a solid foundation to meet that mission with excellence at every turn.”

As the leader in attack submarine maintenance, repair, and modernization, Portsmouth Naval Shipyard stands at the forefront of America's commitment to peace through strength, delivering combat-ready submarines that are lethal, resilient, and prepared to win. PNSY strengthens the maritime industrial base and invests in its highly skilled workforce through a focus on innovation, accountability, and fostering a culture of warfighting excellence.
