What General Dynamics Nassco-Norfolk does

General Dynamics NASSCO-Norfolk is a US Navy ship maintenance, repair, and modernization (MRO) provider operating two full-service shipyards in Hampton Roads, Virginia—the Ligon Street Yard in Norfolk and the Harper Avenue Yard in Portsmouth. The company was formed from the consolidation of the former Metro Machine Corporation and Earl Industries, both with over 50 years of operational history in the region, and now operates as a subsidiary of General Dynamics Corporation (NYSE: GD) within its Marine Systems segment. NASSCO-Norfolk holds a Master Ship Repair Agreement (MSRA) and Agreement for Boat Repair (ABR), qualifying it for complex, restricted, and technical availabilities on US Navy vessels of all classes, including aircraft carriers, destroyers, submarines, and amphibious ships.

The company's service portfolio spans structural fabrication, mechanical, electrical, blast and paint, lagging, engineering, and program/project management—delivered through certified ASME and MIL-STD welding, NDE/NDT capabilities, and a proprietary process for in-place cleaning of electrical rotating equipment. The Ligon Street facility features a 40,000LT drydock capable of docking LHD-1 and LHA-6 Class amphibious vessels, three piers (up to 1,117 feet long), five tower cranes, and full industrial shops; the Harper Avenue facility covers 60 acres with a Navy-approved Pier #1 (799 feet) rated for combatant and amphibious ships up to LPD-17 class, plus 50,000 square feet of environmentally controlled covered shops.

NASSCO-Norfolk generates revenue through direct contracts with the US Navy awarded via competitive procurement, with no public pricing disclosures. Recent contract activity includes $273.45 million across three Navy awards in April 2026 (USS Truxtun DDG-103 maintenance at $183.23 million, submarine non-nuclear support at $55.55 million, and nuclear regional maintenance support at $34.68 million), and participation in a $1.7 billion contract for construction of T-AO 215 and T-AO 216 John Lewis-class fleet replenishment oilers. The company is also pursuing the US Navy's Next Generation Logistics Ship (NGLS) program through a tri-party partnership with Samsung Heavy Industries and DSEC Co., signaling a strategic move into next-generation shipbuilding with advanced automation and digital twin technologies.

• General Dynamics NASSCO: Sister shipyard under General Dynamics Marine Systems, located in San Diego, performing Navy auxiliary ship new-construction (including T-AO 215/216) and surface ship repair. Same parent, same MSRA contracting model, complementary Pacific Coast footprint.
• Vigor Marine Group: Major US ship repair, modernization, and conversion contractor with yards in the Pacific Northwest and Alaska, holding MSRA qualifications and servicing Navy and commercial vessels. Comparable capability profile to NASSCO-Norfolk, though primarily Pacific Coast geography.
• Bollinger Shipyards: Louisiana-based shipbuilder and repairer with extensive Gulf Coast presence, performing Navy patrol boat construction and ship repair work. Competes in the broader US private ship repair and new-construction market for Navy contracts.
• East Coast Repair & Fabrication: Norfolk-based ship repair and metal fabrication contractor performing structural, mechanical, and piping work for Navy and commercial vessels. Directly comparable small-to-mid-scale MRO peer in the Hampton Roads region.

Others

• Samsung Heavy Industries: South Korean global shipbuilder partnered with NASSCO-Norfolk via December 2025 tri-party MOA on US ship design and automation, including NGLS. Partner and technology supplier rather than a competitor in the US Navy MRO market, but materially relevant for capability transfer.

Regional players

• Pacific Shipyards International: Honolulu-based shipyard performing Navy ship repair and maintenance in the Pacific region, including Pearl Harbor work. Comparable Navy MRO services but geographically distinct from NASSCO-Norfolk's Atlantic footprint.

Broad incumbents

• Huntington Ingalls Industries: Largest US military shipbuilder, operating Newport News Shipbuilding (carrier/submarine new-construction) and Ingalls Shipbuilding (surface combatants) plus an MRO footprint through AMSEC. Competes with NASSCO-Norfolk on Navy surface and submarine maintenance availabilities and is the dominant private yard in the Hampton Roads region.
