US Navy unveils Advanced Electric Stealth Ship Demonstrator

Among the first technologies tested will be an underwater discharge waterjet propulsion concept with the goals of providing increased propulsive effiency, reduced acoustic signature, and improved maneuverability over previous Destroyer Class combatants.

The Advanced Electric Ship Demonstrator (AESD), Sea Jet, funded by the Office of Naval Research (ONR), is a 133-foot vessel located at the Naval Surface Warfare Center Carderock Division, Acoustic Research Detachment in Bayview, Idaho.

Sea Jet will operate on Lake Pend Oreille, where it will be used for test and demonstration of various technologies.

Among the first technologies tested will be an underwater discharge waterjet from Rolls-Royce Naval Marine, Inc., called AWJ-21, a propulsion concept with the goals of providing increased propulsive effiency, reduced acoustic signature, and improved maneu

Unlike conventional waterjets (Rolls Royce WaterJet system pictured) , the system works completely underwater, reducing noise and surface wake and improving stealth.
