Arlington, Va.—The Office of Naval Research announces the christening of the Advanced Electric Ship Demonstrator (AESD) on August 24, 2005. The ceremony will take place at the Naval Surface Warfare Center Carderock Division, Acoustic Research Detachment in Bayview, Idaho.

Chief of Naval Research Rear Admiral Jay M. Cohen will deliver the principle address at the christening. The ship’s sponsor is Kathleen Harper, wife of Thurman Harper, vice president of engineering for Rolls-Royce Naval Marine, Inc. In the time-honored Navy tradition, she will break a bottle of champagne across the bow to formally christen the ship "Sea Jet."

The 133-foot vessel will serve as a model representing a destroyer-size surface ship and will be launched on Lake Pend Oreille, Idaho, where it will be used for test and demonstration of various technologies. An underwater discharge waterjet from Rolls-Royce Naval Marine, Inc., called AWJ-21 ™, will be among the first technologies tested. It allows vessels to operate in shallow water with increased maneuverability and stealth.

Following demonstration of the AWJ-21, the RIMJET propulsor from General Dynamics Electric Boat will be installed in Sea Jet for evaluation. The RIMJET is a novel type of podded propulsion system that relies on a permanent magnet motor to drive the propellor.

Reporters wishing to attend should identify themselves as press at the front gate. Photos and video footage will be available shortly after the event from ONR’s online media gallery at http://www.onr.navy.mil/media/.

Navy Christens the Advanced Electric Ship Demonstrator

The US Navy's Office of Naval Research has unveiled its new advanced electric-ship demonstrator ship, SEA JET, for the first time.

The ship will test Rolls-Royce patented AWJ-21(TM) waterjet technology over the next six months on Lake Pend Oreille at the Navy's Acoustic Research Department in Bayview, Idaho.

The AWJ-21 is designed to increase ship speed, making hulls sleeker by working without rudders, shafts and propeller struts. Unlike conventional waterjets, the system works completely underwater, reducing noise and surface wake and improving stealth.

The lightweight and compact AWJ-21 allows ships to operate in shallow waters. Its integrated steering and reversing system improves maneuverability at low speeds.

Pat Marolda, Rolls-Royce President -- Naval, said: "This is a significant milestone in our development of an advanced waterjet technology which offers new parameters in performance, bringing real benefits to the US Navy."

It's a GERERATOR!

I have a radio controlled boat I purchased from "Toys-R-Us" a few years ago with the same type motor.

It even has a water gun to put fires out with (Coast Guard version) - a real blast with kids around until they submerge it like a toy.
