SPEED

At 52 meters (170 feet), weighing 250 tonnes, and capable of up to 30 knots, Spectre is the largest, fastest, and most capable Saildrone platform to date, supporting complex, demanding naval missions in two variants.

Spectre Silent Endurance is optimized to support anti-submarine warfare payloads—missions demanding extreme endurance and an ultra-quiet acoustic signature—by leveraging the proven endurance, reliability, and silent propulsion of the Saildrone wing system.

Spectre Stealth, a wingless variant, is optimized for low-profile, higher-speed operations with concealed payload capacity for modular effectors and other mission systems.

SPECTRE SILENT ENDURANCE

Extreme range with quiet persistence for ASW and ISR

Spectre Silent Endurance leverages dual electric and diesel propulsion supplemented by the Saildrone Wing to enable near-silent electric propulsion up to 12 knots—providing the extreme range and quiet propulsion necessary for long-duration anti-submarine warfare operations. The wing also provides the sensor advantages associated with a 43-meter height-of-eye.

SPECTRE STEALTH

Low‑profile operations for high-speed mission execution

Spectre Stealth, which operates without a wing, maintains a lower profile, enabling a higher maximum speed and reducing the likelihood of detection in sensitive or contested environments. This lower-profile variant is also optimized for offensive missions such as strike or electronic warfare.
