Saildrone Unveils “Spectre” USV: Next-Gen Autonomous Platform Targets Anti-Submarine Warfare Missions

Developed with Lockheed Martin and backed by advanced certification standards, the 54-meter unmanned vessel aims to deliver stealth, speed, and scalable ASW capability ahead of 2027 sea trials.

At the annual Sea-Air-Space Exposition, maritime defense firm Saildrone announced a major expansion of its unmanned fleet with the introduction of the Spectre, a new class of unmanned surface vessel (USV) purpose-built for anti-submarine warfare (ASW).

The Spectre represents Saildrone’s most advanced platform to date, signaling a strategic pivot toward high-end naval missions traditionally dominated by crewed assets. Measuring 54 meters in length and displacing approximately 250 metric tons, the vessel is capable of reaching speeds up to 30 knots while maintaining an ultra-quiet acoustic profile—an essential requirement for effective submarine detection and tracking.

Designed for Stealth, Speed, and Endurance

Unlike Saildrone’s earlier wind-powered platforms, the Spectre introduces a flexible design approach. Two variants were unveiled: one featuring the company’s signature wing system for extended endurance, and another wingless configuration optimized for speed and stealth in contested environments.

Founder and CEO Richard Jenkins emphasized that the design reflects evolving mission requirements in modern naval warfare.

“While the Saildrone wing is ideal for long-duration missions, certain operational environments demand greater stealth and speed without the need for extended endurance,” Jenkins said during the unveiling.

The vessel’s low acoustic signature and autonomous capabilities position it as a force multiplier in undersea warfare, particularly in regions where adversary submarine activity is increasing.
