Copperhead

A family of high-speed autonomous underwater vehicles that can be launched from larger undersea drones (such as Dive-LD/Ghost Shark-class craft). Four variants are offered: the Copperhead-100 (12.75-inch / ~324 mm diameter, ~2.5 m long, ~45 kg dry) and Copperhead-500 (21-inch / ~533 mm diameter, ~227 kg dry) act as ISR AUVs carrying swappable payloads (extended communications, magnetometer, side-scan sonar, chemical detection), while the Copperhead-100M and Copperhead-500M are torpedo-like underwater strike munitions. All variants sprint at over 30 knots (~56 km/h); Anduril released the first footage of the Copperhead-500M conducting high-agility maneuvers in sea trials in April 2026.

Full specifications

Performance

Speed, range, altitude and engagement capability.

Performance specifications
Max speed Maximum level speed. For aircraft this is at optimal altitude; for ground vehicles, top road speed. Higher means faster response and better kinematic performance.	56 km/h

Physical

Dimensions, weight and crew.

Physical specifications
Crew Personnel required to operate. Fewer reduces exposure; autoloaders trade a loader for mechanical complexity.	0

Propulsion

Engine, power and fuel.

Propulsion specifications
Propulsion type Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet…	Electric motor

Naval

Displacement, speed, endurance and diving depth.

Naval specifications
Max speed Top speed in knots (surfaced, for submarines). Higher aids positioning and screening.	30 kn Top 3% of submarines
