Metro Machine Corp, doing business as General Dynamics NASSCO Mayport, a subsidiary of General Dynamics Corporation, delivers ship repair, maintenance, and modernization services for U.S. Navy surface combatants and Littoral Combat Ships as a prime contractor operating on a full and open (non-set-aside) basis. The company holds two major indefinite delivery contracts with Naval Sea Systems Command valued at $701.2 million through April 2029 and $965 million through August 2026, respectively, anchoring a footprint of 1,155 prime awards spanning nearly three decades. Combined potential value across all recent awards reaches $4.03 billion, with $749.4 million obligated to date.

Metro Machine Corp's customer base is highly concentrated within the Department of the Navy. Naval Sea Systems Command accounts for 610 awards carrying $2.65 billion in combined potential value, while U.S. Fleet Forces Command (Atlantic Fleet) has issued 203 awards worth $1.38 billion. Together, these two Naval commands represent 98% of recent awards. The company's geographic footprint is anchored at Naval Station Mayport in Jacksonville, Florida, where it maintains dedicated shipyard capacity for destroyer, guided missile cruiser, and Littoral Combat Ship maintenance. Work scope includes planned and continuous maintenance availability, emergent ship repair, engineering support, facilities maintenance, corrosion control, and complex modernization efforts for non-nuclear surface combatants and amphibious transport dock vessels homeported in or visiting the Mayport region; representative recent work includes a $573 thousand voyage repair delivery order for USS Minneapolis-St. Paul (LCS 21) in Ponce, Puerto Rico (June 2025), a $1.32 million planned maintenance availability order for USS Nantucket (LCS 27) (January 2025), a $1.81 million combined planned maintenance order for USS Minneapolis-St. Paul and USS St. Louis (February 2024), and a $15.1 million selected restricted availability order for USS Jason Dunham (DDG 109) (August 2022).

Metro Machine Corp operates under five primary parent IDV vehicles. The largest is Indefinite Delivery Contract N6267004D0035, which has generated 331 task orders carrying $106.8 million in combined potential value. The Littoral Combat Ships Sustainment East Coast 2016-2021 vehicle accounts for 75 task orders and $79.5 million. The NAVSEA SE Ship Maintenance Repair and Modernization 2016-2021 multiple-award IDIQ has generated 32 delivery orders worth $126.1 million.

Award activity has grown from five awards in 2022 to a peak of 18 in 2024, though 2025 and early 2026 show a moderation to 13 and 7 awards respectively. Only one award with combined potential value of $1.2 million reaches ultimate completion within the next twenty-four months, presenting minimal near-term recompete exposure. The company's work is classified primarily under NAICS 336611 (Ship Building and Repairing) and PSC code Non-Nuclear Ship Repair (East). Metro Machine Corp carries no federal subcontract awards in the source data; it operates exclusively as a prime contractor. As a General Dynamics subsidiary, the company leverages parent-company resources for engineering, program management, and specialized repair services but executes work independently through its Mayport division.
