Echo Voyager is a fully autonomous extra large unmanned undersea vehicle (XLUUV) class UUV that can be used for a variety of missions that were previously impossible due to traditional UUV limitations.

Echo Voyager is complete with an extensive internal and external payload volume and available energy capacity, expanding the parameters of what is possible in current unmanned undersea systems.

The vehicle’s advanced autonomy enables it to perform at sea for months at a time, delivering a more affordable, mission-capable solution over traditional UUVs.

Boeing has designed and operated manned and unmanned deep sea systems since the 1960s, including Rockwell International legacy systems and U.S. Navy support programs. Prior to Echo Voyager, Boeing developed Echo Seeker and Echo Ranger, autonomous and large UUVs as test beds for its current XLUUV.

Echo Voyager’s advanced autonomy allows it to operate effectively in clear and congested waters without physical human contact.

• Endurance: Echo Voyager’s range covers 6,500 nm (1 fuel module) allowing the vehicle to perform long endurance operations.
• Host ship independent: Echo Voyager is not launched from or recovered to a support vessel, nor does it require a support vessel for operation.
• Modular: The 51-foot-long vehicle is designed to incorporate a modular payload section for multiple uses up to 34 feet in length and 2000 cubic feet in volume, and can include payloads extending outside of its envelope.
• Navigation: The XLUUV’s navigation system features a proven Kalman filtered Inertial Navigation Unit supported by Doppler Velocity Logs and depth sensors offering superior directional accuracy.

Powered by a hybrid combination of battery technology and marine diesel generators, Echo Voyager is truly a game-changing platform, capable of performing as a multi-mission system and playing a pivotal role in future force structure.
