There is some discussion in this article whether to continue building a new class of Navy destroyers named for former chief of naval operations Adm. Elmo Zumwalt.
There is a strong resemblance to the US Navy's Advanced Electric Ship Demonstrator (AESD). This was christened 27 AUG 05.

Selected abstracts of this AESD article:
August 27, 2005 The US Navy christened its Advanced Electric Ship Demonstrator (AESD) this week, naming the futuristic ship SEA JET and showing it to the media for the first time. 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 called AWJ-21, will be among the first technologies tested. It allows vessels to operate in shallow water with increased maneuverability and stealth.
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 manoeuvrability at low speeds.
