Saildrone unveils Spectre for autonomous naval operations
At 52 metres long and weighing 250 tonnes, Spectre is the largest and most capable platform launched so far by uncrewed surface vehicle developer and operator Saildrone. The vessel is designed for long-range autonomous naval operations and represents a significant step forward in the company's push into defence markets.
Navies are increasingly turning to unmanned surface vehicles to maintain persistent maritime presence while preserving crewed assets for higher-complexity missions. Spectre is positioned to meet that demand, combining endurance, speed, and mission flexibility in a single platform.
"Spectre is the result of 25 years of continually pushing the boundaries of what's possible. A unique design evolved through the hard lessons of operational experience in the real world," said Richard Jenkins, Saildrone's founder and CEO. "Spectre is not a craft hurriedly readied to meet a particular RFP, but diligently evolved over multiple years to meet the operational requirements of our customers and fill critical capability gaps in the ASW domain."
Capable of reaching 30 knots, Spectre uses twin shaftlines with dual electric and diesel drive, delivering near-silent propulsion up to 12 knots before engaging 5,000hp of Caterpillar diesel for higher-speed operations. Range extends to 3,280 nautical miles in calm water and 2,790nm in moderate sea conditions, with a 25-tonne payload.
Mission modularity
The vessel comes in two variants. Spectre Silent Endurance is equipped with a Saildrone Wing and optimized for antisubmarine warfare and acoustically sensitive missions, with a range exceeding 8,000 nautical miles. Spectre Stealth Strike takes a wingless configuration, prioritizing speed, low radar signature and kinetic strike capability.
A concealed payload deck supports containerized loads of up to 70 tonnes, accommodating configurations ranging from dual 40-foot containers to five 20-foot units. Payloads are deployed via the transom, with bulwarks providing both concealment and weather protection.
Saildrone is the first USV developer to achieve American Bureau of Shipping class certification, and Spectre has already received Approval in Principle under High Speed Naval Craft standards. The vessel's autonomy software, developed over more than a decade of open-ocean operations, is fully compliant with international maritime collision regulations in day and night conditions.
Saildrone positions Spectre not as a prototype but as an operational capability ready to extend naval reach in contested maritime environments.
