How stealth is it?Measure it in Compact Range.
...The main component of the Compact Range - the Anechoic Chamber - is a fully-shielded room of 9 m (width) by 18 m (length) by 8 m (height). The Compact Range is able to measure antenna radiation patterns and target radar cross sections (RCSs) from 1 GHz to 37.5 GHz and has a quiet zone with the size of a cylinder with diameter 6 m and length 6 m.......

57m Stealth Patrol Vessel
Designed as a low observable, cost-effective multi-purpose platform, the 57m Stealth PV has been developed from ST Marine's 55m PV design. -
DD(X) demonstrator---SEA JET----- debutsThe 133-foot-long steel vessel, built by Dakota Creek Industries of Anacortes, Wash., is a one-quarter-scale model similar to the NavyÂ’s new DD(X) class of destroyers.
With angled sides, knife-blade bow and rudderless underside, the Sea Jet will allow the Navy to test hull and bow designs, as well as new technologies in propulsion, fuels, stealth and materials, program director Steve Shreppler said.
.............
The vessel is equipped with a Rolls-Royce Naval Marine underwater-discharge waterjet propulsion system, which allows ships to maneuver quietly in shallow water and at greater speeds, he said.
Similar to the water-propulsion systems on recreational personal watercraft, the Navy wants to test the characteristics of the rudderless, propellerless propulsion system, Cohen said.
After that system is tested — a process that could take up to two years — the Sea Jet will be revamped for another test. Its stern will be cut off and replaced with one powered by a podded propulsion system developed by General Dynamics Electric Boat that relies on a permanent magnetic motor to drive the propeller, Cohen said.
The vesselÂ’s aluminum deck house eventually will be replaced with one made of composite materials to make it more stealthy, Shreppler said.
