When you pass the south shore of the bay heading toward Coronado, you cross from the recreational waterfront to the working one. The enormous grey cranes appear first — four of them, rising above the roofline of the National Steel and Shipbuilding Company, or NASSCO. Then the dry docks, some empty, some holding steel skeletons in various stages of assembly. Then the noise: grinding, welding, the deep hydraulic sounds of heavy industrial work. It is the loudest quarter-mile on the bay.
NASSCO is the largest new-construction shipyard on the West Coast, one of the last substantial yards on the Pacific coast still building ships from the keel up — not repairing them, not converting them, but building them in a working dry dock. Most other major shipbuilding facilities on the West Coast have closed or shifted primarily to repair work.
The company traces its roots to California Iron Works, established in 1905 near downtown San Diego. The company moved to its current location at 28th Street and Harbor Drive in 1944, when the war effort demanded waterfront production capacity and the federal government was funding expansion of every military-adjacent industrial facility on the Pacific coast. The yard built cargo vessels during World War II and has operated continuously since.
NASSCO builds commercial vessels — tankers, container ships, roll-on/roll-off cargo carriers — for American-flag operators, and has built fleet replenishment oilers for the U.S. Navy. The Navy's fleet logistics depend on oilers, ammunition ships, and supply vessels that keep carrier strike groups operating at sea without returning to port. Several of those vessels were built in the dry docks you can see from JADA's deck.
The cranes at NASSCO are among the tallest structures on the south bay. When a ship is under construction in the dry dock, its hull grows visible above the yard's perimeter fence over the course of months. Workers in hard hats are visible from the water. The scale of the work — thousands of tons of steel being cut, welded, and fitted together into a single hull — is clear from a distance in a way that a factory enclosed in a building cannot be.
San Diego's working waterfront used to extend for miles. The canneries are gone. The military fuel docks are mostly gone. The fishing fleet is a fraction of its historic size. NASSCO is one of the last substantial pieces of industrial waterfront on the bay — still building, still loud, still necessary.
