Orca XLUUV
The Orca XLUUV is a very large, autonomous submarine being developed by Boeing for the U.S. Navy. It is designed to operate independently for months, carrying out missions like mine-laying, surveillance, or anti-submarine warfare without a crew.

TECHNICAL DEFINITION
The Orca XLUUV (Extra Large Unmanned Undersea Vehicle) is an autonomous, diesel-electric submarine developed by Boeing for the U.S. Navy, derived from the Echo Voyager prototype. This naval weapons system is engineered for long-endurance, clandestine undersea missions, featuring a large, modular payload bay for capabilities such as mine countermeasures (MCM), anti-submarine warfare (ASW), and intelligence, surveillance, and reconnaissance (ISR).
BACKGROUND
The Orca is an autonomous underwater vehicle (AUV) that is under development by Boeing and Huntington Ingalls Industries (HII) for the United States Navy.
