September 2005 11 The Office of Naval Research chris- tened the Advanced Electric Ship Demonstrator (AESD) — dubbed Sea Jet — on August 24, 2005, at the Naval Surface Warfare Center Carderock Division, Acoustic Research Detachment in Bayview, Idaho. Chief of Naval Research Rear Admiral Jay M. Cohen delivered 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. The 133-ft. (40-ft.) 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 per- manent magnet motor to drive the pro- pellor. This is what you expect from a capable supplier.
