Saronic Raises $1.75B Series D for Autonomous Vessels
Saronic, a developer of autonomous surface vessels for naval forces, has raised $1.75B in Series D funding led by Kleiner Perkins. The company builds modular ASVs like the 24-foot Corsair and 180-foot Marauder, alongside Echelon command software for mission planning and execution. The capital will expand U.S. shipbuilding capacity at a scale unseen since World War II.
Navy Golden Fleet Sparks ASV Boom
The round closes amid the U.S. Navy's Golden Fleet initiative, which allocates $2.1B for Medium Unmanned Surface Vessel systems. Competitor Seasats raised $20M Series A in March 2026 for small USVs targeting Navy tasks. Saronic's combat-optimized vessels address the Navy's push for attritable swarms in contested waters.
Legacy Shipbuilding Strains Naval Edge
U.S. maritime superiority faces atrophy in domestic shipbuilding since World War II, per company messaging. Geopolitical tensions in the Indo-Pacific demand scalable unmanned fleets. Current solutions lag with slow acquisition cycles and high costs for manned vessels.
Modular ASVs Enable Swarm Tactics
Saronic's vessels feature ISO-based modularity for payloads up to 150 metric tons on the Marauder, with ranges exceeding 5,000 nautical miles. Corsair has logged over 100,000 nautical miles in testing. Unlike Saildrone's survey-focused USVs, Saronic emphasizes high-speed combat and logistics in GPS-denied environments.
As Secretary of the Navy John Phelan noted:
"With Saronic, we went from prototype to production in under a year. That’s rapid innovation."
Veteran Founders Drive DoD Traction
Co-founder Dino Mavrookas, an ex-Navy SEAL with 11 years including combat tours, pairs military insight with private equity experience. CTO Vibhav Altekar led maritime autonomy at Anduril, while COO Doug Lambert scaled Liquid Robotics, acquired by Boeing. CCO Rob Lehman deployed maritime tech via his prior firm Temeku on U.S. combatants.
Kleiner Perkins Backs Production Scale
Kleiner Perkins leads with participation from Advent, Bessemer, and a16z, signaling conviction in defense manufacturing revival. The $9.25B post-money valuation follows a $600M Series C at $4B. This growth capital validates Saronic's $392M Navy production contract awarded in December 2025.
USV Market Scales to Billions
The unmanned surface vehicle market stands at $1.59B in 2025, projected to reach $3.45B by 2030 at 12% CAGR. Anduril has raised over $4.5B for multi-domain autonomy. Navy initiatives like Replicator target half unmanned surface fleets by 2045.
Shipyards Ramp for Fleet Expansion
Saronic invests $300M in Franklin, Louisiana shipyard expansion, creating 1,500 jobs, alongside sites in South Texas and New Orleans. Production milestones include multiple Marauder hulls in months and DARPA selection. Recent hires target maritime engineers near Gulf Coast facilities.
