- Saronic Technologies has chosen Brownsville, Texas, for its $3.2 billion shipyard to manufacture medium- and large-class unmanned and autonomy-capable vessels, the Austin-based startup announced July 16.
- Dubbed Port Alpha, the shipyard and manufacturing facility will produce vessels up to 850 feet, with the potential to expand and manufacture vessels over 1,200 feet, according to the press release.
- The shipyard will also create up to 10,000 jobs, such as welding, machining, fabrication, robotics, software engineering, advanced manufacturing and naval architecture. Construction is expected to begin this year with operations beginning in 2028.
Dive Insight:
Saronic’s Port Alpha shipyard aligns with President Donald Trump’s executive order to rebuild the domestic maritime industries and workforce. It also lines up with Trump’s Maritime Action Plan released in February that’s focused on upgrading government procurement processes and simplifying regulations to ramp up shipbuilding and cut costs.
The site announcement follows Saronic’s closing in a series D funding of about $1.8 billion, bringing the company’s value to approximately $9.3 billion.
Port Alpha has been in the works since Saronic announced its plans in February 2025, with the initial planned investment of more than $2.5 billion. Saronic did not immediately respond to a request for comment regarding the increased investment.
The company conducted a “rigorous” search across the United States for the shipyard’s site, ultimately choosing Brownsville because of the city’s “infrastructure readiness, land scale” and logistics.
“The site provides hundreds of acres of waterfront access, deep-water channel connectivity, multimodal logistics infrastructure, and room for long-term expansion — everything required to anchor a next-generation shipbuilding hub,” the startup said in a statement.
The Port of Brownsville is the only deep-water port located on the U.S.-Mexico border, according to its website. The site is one of Texas’ largest foreign trade zones that include the Brownsville-South Padre Island International Airport, Valley International Airport, Harlingen Industrial Park and Airpark, NAFTA Industrial Park and FINSA Industrial Park at nearby Los Indios.
The Greater Brownsville Economic Development Corp. is also developing a 700-acre industrial technology park to accommodate suppliers and manufacturers supporting companies such as Saronic and SpaceX. The industrial development aims to improve the regional supply chains and draw new investment.
Saronic was established in 2022, and the defense technology startup has progressively grown its U.S. operations. In February 2025, Saronic purchased a shipyard in Franklin, Louisiana to serve as a prototype and production hub for its medium unmanned surface vessel fleet, including its 150-foot autonomous surface vessel Marauder.
In December the same year, Saronic announced plans to spend $300 million expanding the Franklin shipyard to increase production of its ASVs.
Saronic has also been working with major technology and defense companies to streamline operations. The startup collaborating with Nvidia in October 2025 that aims to accelerate upgrades in maritime autonomy and robotics.
The company also teamed up with Path Robotics in February to integrate physical AI for welding robotics at its Franklin shipyard.
And in June, Saronic and defense contractor Castelion jointly launched ASVs with hypersonic weapons.
