Massive Robotic Sub Can Carry Out Months-Long Underwater Missions

A new unmanned robotic submersible designed by aerospace giant Boeing can operate autonomously underwater for months at a time, according to company representatives.
The 51-foot-long (15.5 meters), bullet-shaped Echo Voyager was unveiled earlier this month, and is Boeing’s latest unmanned undersea vehicle. The Echo Voyager is designed to explore the deep sea, and the vehicle’s new hybrid rechargeable power system allows it to operate for months underwater without needing to stop for fuel.

“Echo Voyager can collect data while at sea, rise to the surface and provide information back to users in a near-real-time environment,” Lance Towers, director of Boeing Phantom Works’ Sea & Land division, said in a statement. “Existing [unmanned undersea vehicles] require a surface ship and crew for day-to-day operations. Echo Voyager eliminates that need and associated costs.”
Boeing has designed and operated both manned and unmanned submersibles since the 1960s. The company’s existing fleet of unmanned undersea vehicles includes the 32-foot-long (9.7 m) Echo Seeker and the 18-foot-long (5.5 m) Echo Ranger, both of which can operate underwater for a few days at a time.
