Saronic Corsair USV: Specs, Funding, and Who Builds It

What Is Saronic?

Saronic Technologies is a US defense-maritime robotics company that designs and builds autonomous surface vessels (ASVs), also called uncrewed or unmanned surface vessels (USVs) — self-driving boats built for the US Navy and allied navies rather than for consumers. Saronic was founded in 2022 and is based in Austin, Texas.

The company's business is building the boats themselves, not just the software that runs on them. Saronic designs its hulls, builds them at its own facilities, and is expanding into large-scale shipbuilding through a new shipyard called Port Alpha.

This page is an educational overview: what Saronic makes, who founded it, how it is funded, and how it fits into the broader push toward autonomous defense hardware. It does not cover weapons systems, targeting, or any operational military detail — those decisions sit with the US government and armed forces that operate this equipment, not with the manufacturer's marketing.

The Saronic Vessel Lineup: Corsair, Cutlass, Marauder

Corsair is Saronic's flagship and best-known boat: a 24-foot autonomous surface vessel that launched in 2024 and has become the company's most publicized platform, including reported use in a rescue operation near the Strait of Hormuz. It is built to operate without a crew aboard, running pre-planned or remotely supervised missions for surveillance, patrol, and logistics-support roles.

Cutlass is a smaller 14-foot ASV, and Spyglass is Saronic's smallest at roughly 6 feet, aimed at lower-cost, more expendable missions. At the other end of the range, Marauder is a 180-foot vessel built for sustained, long-range operations — Saronic has stated a top speed above 25 knots, a range up to about 5,400 nautical miles, and a modular payload capacity around 150 metric tons.

Across the lineup, the pattern is the same one seen elsewhere in defense robotics: a family of uncrewed platforms sized for different missions, from small and disposable to large and long-endurance, rather than one do-everything boat. We track other uncrewed defense hardware in our military robots overview.

• Spyglass — ~6 ft, smallest ASV in the lineup
• Cutlass — 14 ft ASV
• Corsair — 24 ft flagship ASV, launched 2024
• Marauder — 180 ft, 25+ knot top speed, up to ~5,400 nm range, ~150 metric ton modular payload

Who Founded Saronic?

Saronic was co-founded in 2022 by CEO Dino Mavrookas and CTO Vibhav Altekar. Mavrookas served on SEAL Team Six with nine combat deployments over roughly 11 years before moving into private equity at Vista Equity Partners, where he led technology investments across government, cybersecurity, and other sectors.

Altekar studied electrical engineering at UC Davis and joined Anduril Industries in 2018, where he worked as an engineering manager on perception software for autonomous defense systems, including leadership on the Royal Australian Navy's Ghost Shark uncrewed submarine program before co-founding Saronic in 2022.

That combination — operational military experience paired with autonomy-software engineering from an established defense-tech company — is a common founder pattern in the current wave of venture-backed defense hardware startups, and it is worth knowing when evaluating any claims the company makes about its own systems.

Saronic Funding: The $1.75B Series D

Saronic closed a $1.75 billion Series D round on March 31, 2026, led by Kleiner Perkins, at a $9.25 billion post-money valuation. New investors in the round included Advent International, Bessemer Venture Partners, DFJ Growth, and BAM Elevate, alongside existing backers 8VC, Caffeinated Capital, Andreessen Horowitz, Elad Gil, and Franklin Templeton.

The round followed an earlier $600 million raise in 2025 that funded a shipyard acquisition (Gulf Craft) and an initial production buildout. The Series D capital is earmarked for scaling manufacturing capacity, including the new Port Alpha shipyard, and for continued vessel development across the Corsair, Marauder, and other lines.

A $9.25 billion valuation for a three-year-old shipbuilder is a striking figure, and it reflects investor appetite for US defense-manufacturing autonomy broadly, not a guarantee of Saronic's long-term execution. As with any privately held company, these are funding-round figures, not a public stock price — Saronic is not publicly traded, despite search interest in "Saronic stock."

Port Alpha: Saronic's New Shipyard

Port Alpha is Saronic's planned next-generation shipyard at the Port of Brownsville, Texas, with the company describing plans to invest more than $2.5 billion in the facility. Saronic has said the yard is designed to produce large numbers of uncrewed vessels annually and to create thousands of jobs in the region, alongside existing operations in Austin and Franklin, Louisiana.

The strategic logic is that autonomous vessels only matter at fleet scale — a handful of hand-built boats does not change naval capacity, but a shipyard purpose-built for repeatable, high-volume uncrewed-vessel production could. Port Alpha is Saronic's bet that shipbuilding capacity, not just autonomy software, is the bottleneck worth owning.

This mirrors a broader theme in defense robotics right now: companies competing as much on manufacturing scale-up as on the underlying technology. For the wider landscape of robotics companies pursuing that kind of scale, see our robotics companies directory.
