Saronic Technologies is an American defense company that designs and mass-produces autonomous surface vessels (USVs) for the United States Navy and allied militaries. Founded in 2022 and headquartered in Austin, Texas, the company builds a family of uncrewed boats ranging from a 6-foot scout to a 180-foot logistics ship, all running on its own AI autonomy software. Saronic's pitch is part technology and part industrial revival: it argues that the United States has lost the shipbuilding capacity it would need in a war with a peer adversary, and that the fix is a new kind of vertically integrated yard that turns out uncrewed ships at commercial speed and scale. [1][2] In March 2026 the company raised a $1.75 billion Series D at a $9.25 billion valuation, led by Kleiner Perkins, making it one of the most valuable defense startups in the country. [3][4]
Saronic was started in March 2022 by Dino Mavrookas, who serves as chief executive. Mavrookas spent 11 years as a U.S. Navy SEAL, including roughly five years with SEAL Team Six, before leaving the service in 2015 to work in private equity and technology investing. He has said he quit his investing job in March 2022 to start the company and launched Saronic about six months later. [5] The other founders came from software and hardware rather than traditional defense primes, and Vibhav Altekar serves as chief technology officer. [5][6]
The founding argument is blunt. China now builds commercial and naval ships at a rate the United States cannot match, and American yards are too few, too slow, and too expensive to surge production in a crisis. Mavrookas frames Saronic's answer as "commercial speed, military rigor": design vessels for autonomy from the keel up, manufacture them with techniques borrowed from automotive and aerospace, and fund the whole effort largely with private capital instead of waiting for government development money. [5][6] The company has hired from SpaceX, Tesla, and Silicon Valley software firms alongside experienced naval architects, which it describes as deliberately changing the culture of shipbuilding. [7]
This places Saronic alongside a wave of venture-backed defense technology firms, most prominently Anduril Industries, that are trying to displace legacy contractors with autonomous systems and software-first design. It also fits the Pentagon's Replicator initiative, the Department of Defense effort to field large numbers of cheap, attritable autonomous weapons, including uncrewed surface vessels, on a compressed timeline. [7]
Saronic builds six classes of autonomous surface vessel, identified internally as Tier I through Tier III platforms. The small craft (Spyglass, Cutlass, Corsair) have been built and tested; the larger ships (Mirage, Cipher, Marauder) were unveiled across 2025 and are in various stages of build and trials. The smaller boats handle missions such as maritime domain awareness, surveillance, and surface strike, while the larger vessels are aimed at logistics, longer endurance, and heavier payloads. [8]
| Vessel | Length | Range | Payload | Top speed | Status |
|---|---|---|---|---|---|
| Spyglass | 6 ft | ~30 nm | ~40 lb | ~20 kn | Built and tested |
| Cutlass | 14 ft | ~300 nm | ~200 lb | ~20 kn | Built and tested |
| Corsair | 24 ft | ~1,000 nm | ~1,000 lb | 35+ kn | In production |
| Mirage | 40 ft | 2,000+ nm | ~2,000 lb | 35+ kn | In development |
| Cipher | 60 ft | 3,000+ nm | ~10,000 lb | 35+ kn | In build |
| Marauder | 180 ft | ~5,400 nm | ~150 metric tons | 25+ kn | On-water trials (2026) |
The Corsair, a 24-foot modular boat, is the company's flagship and the platform behind its largest contract to date. Saronic describes it as a blue-water vessel suitable for missions ranging from intelligence gathering to kinetic and non-kinetic strike. [9][10]
The Marauder is the outlier in size. Saronic first unveiled it in April 2025 as a "150-foot" medium unmanned surface vessel (MUSV) when it announced the Gulf Craft acquisition; by the time the first hull launched, the company and most coverage described the ship as 180 feet, reflecting a design that grew during development. [11][3] The first Marauder hull was laid down in August 2025 and entered on-water trials at the Franklin, Louisiana yard on May 31, 2026, having gone from initial design to launch in under a year. It can carry roughly 150 metric tons (its payload has also been described in pounds, around 330,000 lb) in standard 40-foot or 20-foot ISO containers or other modular configurations, travel up to about 5,400 nautical miles, and operate either fully autonomously or under remote human supervision. [12][11]
Every Saronic vessel runs on Echelon, the company's command-and-control and autonomy stack. Altekar has called it "our brain," describing it as "the connective tissue that lets dozens or hundreds of USVs operate autonomously in coordination." [6] Saronic markets Echelon as a tightly integrated software and hardware system rather than a bolt-on autonomy kit, with the goal of faster onboard decisions and coordinated, swarm-style behavior across many boats at once. [13]
The underlying design is an open, modular architecture meant to let operators integrate new sensors, payloads, and third-party systems without re-engineering the core software. [8] That modularity is central to the company's commercial argument: the same hull can be reconfigured for surveillance, logistics, or strike depending on the payload, and software updates can change a fleet's behavior without touching the steel.
Saronic's manufacturing strategy runs on two tracks: scaling the yards it already operates, and building a much larger purpose-designed facility called Port Alpha.
The company first announced Port Alpha in February 2025 as a "next-generation" shipyard designed from the ground up to mass-produce autonomous vessels. Mavrookas described the ambition as building ships "at a speed and scale not seen since World War II." [14][2] No final site had been chosen at launch; executives said they would work with federal and state governments to pick a location. Reporting later identified Brownsville, Texas, on the Gulf Coast near SpaceX's Starbase, as a likely site, with public filings describing a proposed multibillion-dollar project developed in phases through the mid-2030s and contingent on tax incentives. [11] Saronic has said Port Alpha would have roughly ten times the capacity of its existing Franklin yard. [4]
In the near term, Saronic expanded through acquisition. In 2024 it took over a roughly 420,000-square-foot production facility in Austin. [10] In April 2025 it acquired Gulf Craft, a shipbuilder in Franklin, Louisiana, to add hull production capacity quickly rather than wait for a greenfield yard. [11] In December 2025 the company committed $300 million to expand the Franklin yard by more than 300,000 square feet, a project it says will create about 1,500 jobs and that Defense One reported should let the site build around 20 vessels a year. [9][4]
Saronic's anchor customer is the U.S. Navy. In December 2025, at the Reagan National Defense Forum, the Navy awarded the company a $392 million production contract for the Corsair, with nearly $200 million obligated at the time of award. Navy Secretary John Phelan presented the deal as a benchmark for faster procurement: the program moved from prototype to production in under 12 months, far quicker than a conventional shipbuilding acquisition. [9][15]
Saronic has also pushed into allied markets. As part of a 2025 expansion it opened offices in Sydney and Canberra, Australia, and in London and Portsmouth, United Kingdom, to work with AUKUS partners and other NATO allies, and it has said it plans to expand its Australian operations further. [13][16] The Series D announcement framed much of the new demand as coming from both U.S. and allied customers wanting greater range, endurance, and payload, the requirements that drive the larger Cipher and Marauder ships. [3]
Saronic raised capital quickly and at steadily rising valuations, reaching unicorn status within about two years of founding and crossing a $9 billion valuation roughly a year after that.
| Round | Date | Amount | Valuation | Lead investor |
|---|---|---|---|---|
| Series A | October 2023 | $55 million | not disclosed | Caffeinated Capital |
| Series B | July 2024 | $175 million | ~$1 billion | Andreessen Horowitz |
| Series C | February 2025 | $600 million | ~$4 billion | Elad Gil |
| Series D | March 2026 | $1.75 billion | $9.25 billion | Kleiner Perkins |
The $55 million Series A in October 2023 was led by Caffeinated Capital with participation from 8VC, the U.S. Innovative Technology Fund, and Andreessen Horowitz. [17] The $175 million Series B in July 2024 was led by Andreessen Horowitz and valued Saronic at about $1 billion, the point at which it became a unicorn, with 8VC, Caffeinated Capital, Elad Gil, and NightDragon also taking part. [18] The $600 million Series C closed in February 2025, led by Elad Gil with General Catalyst joining alongside a16z, Caffeinated Capital, and 8VC, and roughly quadrupled the valuation to about $4 billion. [19]
The $1.75 billion Series D closed on March 31, 2026, at a $9.25 billion valuation. Kleiner Perkins led the round, and new investors included Advent International, Bessemer Venture Partners, DFJ Growth, and BAM Elevate, with continued backing from 8VC, Caffeinated Capital, Andreessen Horowitz, Elad Gil, and Franklin Templeton. [3][4] By the time of the Series D the company employed more than 1,300 people. [3] Saronic said the capital would go toward scaling its vessel family, advancing Echelon, expanding the Franklin and Texas facilities, and developing Port Alpha. [3][20]
