US Navy Bets Big on 180-Foot Autonomous Warship After Flawless Trials
Saronic’s Marauder completed 140+ test scenarios without a single failure during eight days of continuous operations.
The U.S. Navy has awarded Saronic Technologies a production contract for its 180-foot Marauder autonomous ship following successful at-sea evaluations. The vessel completed over 140 test scenarios during eight consecutive days of round-the-clock operations without any failures.
The contract, a firm-fixed-price Other Transaction award, was granted under 10 U.S.C. § 4022(f) through the Navy’s Medium Unmanned Surface Vessel (MUSV) Marketplace. This initiative aims to expedite the deployment of unmanned surface vessels by utilizing commercially mature technology rather than traditional, lengthy procurement processes.
During testing, the Marauder demonstrated its ability to track and maneuver around other vessels without human intervention. It also completed passive-perception challenges, where it had to detect, track, and follow ships using only its onboard passive sensors—active radar was not permitted. These tests are considered among the most technically demanding for autonomous maritime systems.
Streamlining Autonomous Ship Acquisition: Navy
The MUSV Marketplace was created to accelerate the Navy’s adoption of unmanned surface vessels. Unlike conventional defense procurement, which can span years, this program leverages existing commercial technology to reduce development timelines. In June 2026, the Navy selected seven companies, including Saronic, for the at-sea testing phase. Saronic’s successful evaluation led to the recent production contract.
Dino Mavrookas, CEO and co-founder of Saronic, highlighted the company’s vertically integrated approach, which combines autonomy, software, hardware, and production processes into a single system. This strategy has enabled faster construction and delivery of the Marauder vessels. The same vessel used in the Navy’s evaluation is now part of the production contract.
Saronic has already completed its third Marauder hull, with additional vessels in production at its shipyard in Franklin, Louisiana. The company’s ability to design and build these components simultaneously has allowed it to scale production efficiently.
Testing and Commissioning Operations
To support final testing and commissioning, Saronic has established a facility at the Port of Gulfport in Mississippi. The site spans over 30,000 square feet and includes port access, office space, and warehouse areas. A team of Mission Operations and Commissioning specialists conducts on-water trials and final tests for each Marauder before delivery.
The first Marauder arrived in Gulfport in mid-July and has since undergone hundreds of hours of testing, operating for more than 12 hours daily, seven days a week. As production increases, additional vessels will be transported to Gulfport for final evaluations before being handed over to the Navy.
The Marauder’s performance—operating continuously for days and passing rigorous tests—demonstrates that unmanned maritime systems are transitioning from experimental prototypes to operational readiness.
