Sea Jet, or Advanced Electric Ship Demonstrator (AESD),[1] is a naval testbed funded by the U.S. Navy's Office of Naval Research. The 133-foot (41 m) vessel is operated out of the Carderock Division's Acoustic Research Detachment in Bayview, Idaho.[2] Sea Jet was operated on Lake Pend Oreille, where she was used for test and demonstration of various technologies. Among the first technologies tested was an underwater discharge water jet from Rolls-Royce Naval Marine, Inc., called AWJ-21, a propulsion concept with the goals of providing increased propulsive efficiency, reduced acoustic signature, and improved maneuverability over previous Destroyer Class combatants.[3]

Sea Jet demonstrates a few technologies that will be integrated into the Zumwalt-class destroyer.[1] Notable among these is the return of the tumblehome hull design.

Pend Oreille Paddler

In March 2007, an image surfaced of the mythical lake monster, the Pend Oreille Paddler. A cryptozoology website and blog, Cryptomundo, wrote an article on the new images of the Paddler, questioning whether the object in question was in fact the Paddler or a cover story deployed by the U.S. Navy.[4] In fact, the image is of Sea Jet crossing the lake.
