Brownsville will be the site of Port Alpha, a new shipyard announced by autonomous surface vessel maker Saronic that the company says will begin construction this year and open in 2028. Company leadership described the project as a multi-phase, greenfield shipyard that would significantly expand U.S. shipbuilding capacity.
Project scale and timeline
Saronic says the first phase of Port Alpha will cover 850 acres and provide as much as 150,000 gross tons of shipbuilding capacity, with the capability to assemble vessels up to 850 feet long. Company executives told reporters the initial phase alone will boost national shipbuilding output by roughly 1.5 times, with long-term plans to grow the facility to as much as 2 million gross tons over the life of the project. Saronic expects on-site work to start this year and for operations to begin in 2028.
“Just phase one alone will make this the largest shipyard in the United States,” Saronic CEO Dino Mavrookas said.
What Saronic is and why this matters locally
Saronic is an ASV (autonomous surface vessel) company that has scaled quickly since its founding in 2022. The company’s products span smaller unmanned craft to large manned or unmanned hulls, and Saronic has been active in defense contracting. In late 2025 the company disclosed a $392 million Other Transaction Agreement to deliver its 24-foot Corsair ASVs to the U.S. Navy. The firm has also been acquisitive, purchasing Louisiana-based Gulf Craft and indicating prior commitments to invest in shipbuilding capacity.

- Phase one capacity: up to 150,000 gross tons
Financial and industrial context
Public disclosures cited by the company show Saronic has raised significant private capital: a reported total of $2.59 billion to date, including a $1.75 billion Series D that valued the company at about $9.25 billion. Earlier fundraising included a $600 million Series C. The company has said it contributed roughly $300 million toward expanding Gulf Craft after that acquisition.
| Item | Amount or example |
|---|---|
| Total capital raised | $2.59 billion |
| Most recent funding round | $1.75 billion Series D; ~$9.25B valuation |
| Defense award | $392 million OTA for Corsair ASVs |
Local implications and next steps
If Saronic follows through on the announced plan, Port Alpha would be among the largest industrial investments in the region in recent years. The project could affect Brownsville and Cameron County through construction employment, longer-term skilled shipbuilding jobs, port infrastructure demands and logistics traffic. Local officials and trade stakeholders will likely need to address permitting, workforce development and dockside support to accommodate the scale of the proposed yard.
Saronic’s product range spans small unmanned vessels like the 6-foot Spyglass up to larger models introduced after its Gulf Craft purchase, including a 60-foot Cipher and a 180-foot Marauder. The company’s Corsair, a 24-foot ASV, is tied to its Navy award.
Company statements provided the timeline and figures; additional details about site location within Brownsville, local partnerships, expected job counts and financing for port infrastructure were not disclosed in the announcement.
