Seasats builds autonomous maritime systems for defense and scientific data-gathering missions. Its flagship Seasats X3 is an unmanned vessel that can perform dangerous naval ISR tasks without putting humans at risk. The platform operates by autonomously navigating and carrying a configurable set of sensors and electronic warfare tools; clients can lease the vessels and either bring their own sensors or choose from Seasats’ sensor library, with optional training and support. Revenue comes from leasing fees, sensor integration services, and data collection contracts. Seasats differentiates itself with low-logistics, high-efficiency maritime solutions that withstand harsh seas and are easy to transport by air or land, plus flexible pricing and sensor options. The company’s goal is to enable safe, effective autonomous ISR operations for government, research institutions, and large enterprises through adaptable platforms and support.

Simplify's Take

What believers are saying

  • Seasats won a $24 million APFIT award on January 15, 2026.
  • It closed a $20 million Series A on February 17, 2026.
  • Quickfish completed an eight-day trial in March 2026, and Heavyfish launches this fall.

What critics are saying

  • Anduril and Kraken announced small USV production partnerships in April 2026.
  • Seasats still depends on U.S. Navy and Marine Corps contracts for most demand.
  • A failed production ramp or delayed Heavyfish launch in 2026 would crush credibility.

What makes Seasats unique

  • Lightfish crossed the Pacific and Atlantic, proving sea endurance others still lack.
  • Seasats sells sub-$1 million USVs, keeping procurement easier than crewed ships or primes.
  • Quickfish and Heavyfish extend one autonomy stack across interceptor and long-range missions.

Seasats Quickfish USV completes eight-day trial, achieves multi-week endurance capability

Seasats has completed an eight-day continuous sea trial of its Quickfish unmanned surface vessel, demonstrating extended endurance capabilities for the interceptor-class platform. The high-speed USV reaches over 35 knots and is designed for multi-week on-station operations, supporting port security, border protection and coastal defence missions. The Quickfish features a payload bay for delivering unmanned aerial vehicles and combines low-speed electric propulsion with high-speed jet drive. This distinguishes it from similar vessels typically limited to one or two days of endurance. San Diego-based Seasats has secured significant Department of War contracts, including deals with the US Marine Corps in 2025 and 2026. The company previously completed record-setting endurance runs and ocean crossings with its proven Lightfish USV platform.

Seasats raises another $20m for uncrewed surface vehicles

Seasats raises another $20m for uncrewed surface vehicles. Seasats has closed a US$20 million Series A financing round to scale the production of its small uncrewed surface vehicles (sUSVs). The funding, led by Konvoy Ventures, brings the total capital raised by the San Diego−based company to more than $40 million. The investment follows the recent award of over $100 million in US government contracts. The funding is intended to support the expansion of new facilities and the development of additional product lines. Seasats currently produces the Lightfish, a 3.5-metre autonomous vessel designed for long-endurance operations. The solar-electric craft weighs 138 kg and has demonstrated its reliability through a 12,000 km autonomous crossing of the Pacific Ocean. The company focuses on automating tasks that are considered unsuitable for crewed vessels. Its platforms are used for tasks such as port security, coastal patrols, and subsea mapping. "Robotics typically deliver value by automating tasks across one or more of the three D's: dirty, dull, and dangerous," said Mike Flanigan, Chief Executive Officer and Co-founder of Seasats. "We've focused on attacking the 'dull' problem, making vessels that can reliably operate for weeks or months, just like Navy and utility ships do. That approach has won tremendous support from users and investors, and this funding underscores that." The company is currently preparing for the launch of its Heavyfish platform, a 4,082 kg long-range vessel expected to be released in autumn 2026. Rob is Chief Network Officer and one of the founders of Smart Maritime Network. He also serves as Chairman of the Smart Maritime Council. Rob has worked in the maritime technology sector since 2005, managing editorial for a range of leading publications in the transport and logistics sector.

Seasats lands $24M US DoW APFIT award to scale autonomous surface vessel production

Seasats, a developer of long-endurance autonomous surface vessels, has been awarded $24 million under the Department of War's Accelerate the Procurement and Fielding of Innovative Technologies programme. The funding, recommended by the US Navy and Marine Corps, will accelerate production and scaling of the company's maritime technologies. The San Diego-based company was selected following growing Navy adoption of its autonomous vessels for critical maritime applications. Over the past year, Seasats has advanced multiple Navy and Marine Corps programmes, including an $89 million SBIR Phase III contract and operational demonstrations in US and allied waters. APFIT, established in 2022, provides procurement funding to small businesses whose technologies have completed development and are ready for rapid operational deployment.
