Saronic raises $1.75B at $9.25B valuation to scale autonomous warships for US Navy

What's the deal? Austin-based autonomous warship startup Saronic has closed a $1.75 billion Series D round at a valuation of $9.25 billion. The round was led by Kleiner Perkins, with new investors including Advent InternationalDealroom has a profile for this one. Try Dealroom →, Bessemer Venture Partners, DFJ Growth, and BAM ElevateDealroom has a profile for this one. Try Dealroom →, alongside returning backers including  Andreessen Horowitz, and 8VC. The raise more than doubles Saronic's valuation from the $4 billion it achieved during its $600 million Series C in 2025.

Founded by Dino MavrookasDealroom has a profile for this one. Try Dealroom →, Saronic builds autonomous surface vessels ranging from the 24-foot Corsair to the 180-foot Marauder. The company secured a $392 million production contract with the US NavyDealroom has a profile for this one. Try Dealroom → in 2025 and generated just over $200 million in revenue that year. It now employs more than 1,300 people, with facilities in Louisiana, Texas, San Diego, Washington DC, the UK, and Australia.

Why now? The US military is urgently seeking to rebuild maritime capacity after decades of industrial decline. Saronic's pitch — autonomous vessels produced at speed using software-defined manufacturing — aligns directly with that need. The new capital will accelerate construction of Port Alpha, its next-generation shipyard, alongside existing facilities in Louisiana and Texas.

Geopolitical pressure is also a tailwind. Competition with China at sea has made autonomous maritime systems a strategic priority for the PentagonDealroom has a profile for this one. Try Dealroom →, and Congress has been pushing the Navy to expand its unmanned fleet.

What could go wrong? Defence startups effectively have one giant customer — the US military — and contract timelines, budget cycles, and political shifts can derail even the most promising programmes. At $9.25 billion on roughly $200 million in revenue, Saronic is valued at approximately 46 times revenue, a multiple that demands sustained contract wins and consistent delivery.

Capital intensity is another risk. Building ships requires far more sustained investment than software. AndurilDealroom has a profile for this one. Try Dealroom →, a larger and better-resourced rival that recently partnered with Korean shipbuilder HD HyundaiDealroom has a profile for this one. Try Dealroom →, is likely to compete directly for the same government contracts.

The signal: Autonomous defence hardware is attracting venture capital at a scale and speed that reflects a fundamental shift in how investors view military power. Saronic's raise — $1.75 billion in a single round — signals conviction that the next era of defence will be defined not just by software, but by the industrial capacity to manufacture autonomous systems at scale.

The debate is no longer whether defence tech deserves venture capital. It is whether the valuations being assigned can ever be justified by the returns.
