Submarine Design, Construction and Fleet Services

two_thirds-constructionUsing expertise developed from building dozens of submarines, Newport News Shipbuilding is one of only two shipyards capable of designing and building nuclear-powered submarines. We also provide design and engineering services and fleet maintenance support around the world.

New construction

We are building the U.S. Navy’s newest and most advanced attack submarines in the world — the Virginia-class. Designed to meet the Navy’s requirements in a post-Cold War era, Virginia-class submarines use advanced technologies to increase firepower, maneuverability and stealth. The 377-feet long submarines are capable of submerged speeds of more than 25 knots and can stay submerged for up to three months at a time.

Under an innovative agreement, Newport News Shipbuilding is producing these submarines as part of a team with General Dynamics Electric Boat. The team has been recognized as the best shipbuilding program in the Navy. Learn more about the Virginia-class

Prior to the Virginia-class, Newport News Shipbuilding designed the Los Angeles-class submarine and constructed 29 of the 62 boats built.

Design and engineering

Newport News is the Navy’s planning yard for the Los Angeles-class and Seawolf-class attack submarines. This involves the design and on-site installation of state-of-the-art technology to keep the submarine fleet the most capable in the world.


two_thirds-fleetservicesFrom design through construction, maintenance, and disposal, our fleet support organization is committed to providing quality services to the submarine community. Our portfolio of fleet service offerings includes both mobile and in-house capabilities.

Our mobile “Tiger Team” provides submarine modernization and repair services at the naval shipyards, fleet homeports and wherever the need is around the world. We provide the submarine fleet sonar and combat systems installation services including WSQ-9, Total Ship Monitoring System (TSMS), Advanced Rapid COTS Insertion (ARCI) and BYG-1. We are also one of only two private shipyards authorized by NAVSEA to perform SUBSAFE work on submarines.

We continue to provide the submarine community with needed surge capacity performing quality maintenance, modernization and repair services at our facility as well.
