ShadowDart, ShadowHawk, and ShadowRay at sea, with a second ShadowRay submerged below
ShadowSwarm™

Complementary robots. Coordinated missions.

ShadowRay, ShadowDart, and ShadowHawk are designed to cover surface, subsurface, and air, coordinated through POSEIDON.

ShadowRayIn development

Surface. Foil. Dive.

ShadowRay is designed to work on the surface, lift onto hydrofoils for high-speed transit, and dive to operate below, all in one 5 m electric hull, moving between the three within a single mission. We know of no other vessel designed to do all three.

ShadowRay submerged
Submerged
01

Surface

Holds station, launches and recovers, and senses from the surface like a conventional uncrewed vessel.

02

Foiling

Lifts the hull clear of the waves on hydrofoils to cover distance at speed.

03

Submerged

Dives to transit quietly and sense below the surface, then surfaces to report.

ShadowHawkIn development

Eyes above the horizon.

An extended surveillance drone designed to give the fleet a wide view from above, searching and identifying across the operating area. Intended to launch from ShadowDart at sea.
