Overview
Large high-speed Saildrone USV class for naval ASW, ISR, strike, and persistent payload-effect missions.
Saildrone Spectre is a military medium unmanned surface vessel class developed by Saildrone in the United States. The April 2026 official release describes Spectre as a 52 m, 250 tonne high-speed USV designed for persistent anti-submarine warfare, ISR, and strike missions. The vessel uses twin shaftlines with dual electric and diesel propulsion, enabling near-silent electric operation up to 12 knots and diesel sprint performance up to 27 knots with full fuel and a 25,000 kg payload. Published specifications captured here include 3,280 nautical miles of flat-water range at 25 knots with that payload, 2,790 nmi in Sea State 4 head sea, maximum payload over 70 tonnes, and a concealed payload deck that can host containerized mission systems. Saildrone describes two mission configurations: Silent Endurance with wing assist for extreme range and quiet ASW, and Stealth Strike with a lower-profile wingless arrangement for higher-speed strike missions. The design has ABS Approval in Principle and is planned for Fincantieri production with first sea trials expected in early 2027.

Saildrone released the Spectre design in April 2026, with ABS Approval in Principle and construction planned through Fincantieri's Wisconsin shipyards. First sea trials are expected in early 2027. Range_km uses the published 3,280 nmi flat-water range at 25 kt with a 25,000 kg payload; the wing-assisted Silent Endurance configuration is separately described as exceeding 8,000 nmi.
