The USNS Harriet Tubman and Its Mission
The USNS Harriet Tubman is a John Lewis-class fleet oiler that has been under construction since 2025. These 742-foot vessels carry 157,000 barrels of oil and supply fuel to Navy carrier strike groups at sea. The Navy awarded NASSCO the contract in 2016 to build this class of ships. Seven ships are planned in total, including USNS John Lewis, USNS Harvey Milk, and USNS Earl Warren.

General Dynamics NASSCO confirmed damage was minimal, with gymnasium and workout equipment being mostly affected. No hazardous materials were involved.
What This Means for Naval Construction
The incident demonstrates the scale of military shipbuilding in San Diego and the coordination required between military and civilian fire services. NASSCO maintains its own fire department and works with local agencies during emergencies. The quick response prevented escalation and protected a vessel worth hundreds of millions of dollars under construction.
