Mare Island Company acquires the dry dock — and bids for a federal shipbuilding designation

The Mare Island Company has acquired Mare Island Dry Dock out of bankruptcy and is positioning the island for large-scale shipbuilding — a commercial play that would dwarf anything currently on the island if it lands.

Why the dry dock was available

Mare Island Dry Dock announced its permanent closure on December 30, 2025, terminating all employees after losing a critical U.S. Coast Guard contract — maintenance of the icebreaker USCG Healy, which went to Vigor Marine in Portland. The company's CEO said 2025 was its slowest year in its 13-year operating history.

The play: control the property

The Mare Island Company stepped in not to run a shipyard but to control the property. Brian Nagy told the Solano Association of Realtors' marketing meeting they're in active talks with potential users from around the world and hope to land a tenant this year — with a campus in the 50–80 acre range and thousands of jobs attached. That's an aspiration, not a signed deal.

The federal tailwind

The backdrop is favorable. The Nimitz Group has teamed up with California Forever to submit a proposal designating portions of land across five counties surrounding the Sacramento–San Joaquin Delta as Maritime Prosperity Zones, part of the administration's plan to revitalize American shipbuilding. Congressman Garamendi has been pushing the SHIPS for America Act, which he expects to reach the president's desk in 2026.

The catch

The same infrastructure problems blocking residential development on the island apply equally here — any large shipbuilding operation would require significant utility investment before breaking ground. But if the federal shipbuilding push is real and a major user commits, Mare Island has the waterfront, the dry docks, and the history to make the case.

Update — June 2026: Vallejo goes all-in on the maritime bet

The story now has a second player: the City of Vallejo itself. In May 2026, the Vallejo City Council heard a formal maritime revival plan and authorized a $210,000 contract with the Roosevelt Group, a defense lobbying firm, to pursue federal maritime investment for the city. The three-pillar strategy: industrial revitalization on Mare Island; a long-term push to restore a Coast Guard or Naval presence in Vallejo; and building a maritime workforce pipeline. Congressman Garamendi's SHIPS for America Act — which he has said he expects to pass in 2026 — is the federal vehicle the city is positioning for. A city-level lobbying contract and a private developer's tenant search are not a signed deal. But Vallejo is no longer waiting on the sidelines.

My read for clients

For investors, this is the most interesting wildcard on the island. A major employer with thousands of jobs would reshape the entire Vallejo demand picture — and Mare Island values — in a way residential build-out alone wouldn't. The city's formal maritime bet adds credibility to the thesis: it's no longer just a private developer's pitch. But it's still speculative: no signed tenant, unresolved infrastructure, and a federal program still finding its footing. Don't underwrite a Mare Island investment on the shipyard happening — underwrite it on today's reality and treat the shipbuilding upside as a free option.
