Sea Launcher is HII’s shipboard system that can launch and recover REMUS UUVs autonomously, featuring a strong-back aluminum frame, and a carbon fiber recovery cradle.

HII’s REMUS unmanned underwater vehicle (UUV) can now be launched and recovered from ships entirely autonomously, thanks to the new Sea Launcher system.

Measuring 18 feet (5.5 meters) long and 2 feet (0.61 meters) wide, the device weighs 800 pounds (363 kilograms) without the UUV onboard.

Its strong-back aluminum base frame is reinforced with carbon fiber, paired with a carbon fiber recovery cradle that features soft support rails to protect the vehicle.
