The Littoral Combat Ship (LCS)

"Purpose: This is a small, fast ship (capable of 45 knots) for sub-hunting, mine-clearing, and fighting small boats near coastlines—the littoral region. Each LCS would be equipped with one of three distinct mission modules: a set of plug-and-play ship sensors, missiles, small boats, unmanned underwater vehicles and specially equipped helicopters, for mine warfare, anti-submarine warfare or surface combat. The base configuration would include antimissile batteries and a medium-caliber gun. The ships could clear mines and chase subs away from an area before the rest of the fleet arrived."

"ElectroWave USA designed an Engine Order Telegraph for the brand new United States Navy Littoral Combat Ship (LCS). To equate this technology to the old devices; if you remember in the old movies with ships (like Titanic), the person on the bridge would move these large brass handles between indications like "Full Ahead" "Slow Ahead" "Dead Stop", etc. The ElectroWave USA EOT is its modern day equivalent.

The EOT was designed to be PLC based (a USN requirement), and operate a number of water jet engines. ElectroWave USA designed a system that could easily be marketed to other types of ships. The ElectroWave USA EOT is now listed in the US Navy Catalog as a standard orderable product. You will find a few pictures below of our test and demonstration stand here at the factory."

"Why New Warships Will be Powered by Waterjets"
http://www.marinelink.com/Story/WhyNewWarshipsWillbePoweredbyWaterjets-206051.html
"What was once a way to makes waves with small craft, contemporary high-powered waterjet propulsion systems are winding up on bigger vessels including warships. Why waterjets? They are simple and reliable, with the pump impellor turning at a constant speed and flow in one direction. Engine loading is constant. In most cases a gearbox is not required. The entire propulsion system receives less stress and requires less maintenance. Waterjets have plenty of pickup, can sustain high speed operations, but can stop on a dime by reversing thrust. They’re responsive, and idea for precise maneuvering or station keeping. Waterjets can be used in very shallow water. There’s no screw to foul.

Waterjets-powered craft can operate close to and up to the shore, and even run over obstructions without damaging the propulsion equipment. Flotsam and jetsam are not big problems, even at high speed. At slow speed these may be sucked into the jet unit but are unlikely to cause damage and can easily be removed.

And waterjets are fast. They pack a lot of power in a small amount of space. There are other qualities that make waterjets a wise choice for a combat craft. Because they have no turning props, these ships emit less noise and so are less susceptible to sonar or acoustic mine detection. Lower noise and less vibration delivers a more quiet and comfortable ride for passengers. Waterjets eliminate the screws and rudders that make launching and recovering small boats, unmanned vehicles or swimmers a dangerous and difficult evolution."


"USS Freedom (LCS 1) employs two Rolls-Royce MT30 36MW gas turbines and two Fairbanks Morse Colt-Pielstick 16PA6B STC diesels. The hull is based on Fincantieri’s high-speed yacht Destriero, the Transatlantic crossing record-holder at 60 knots. The 378-ft. Freedom has a steel hull with aluminum superstructure. Two Rolls-Royce MT30 36MW gas turbines and two Fairbanks Morse Colt-Pielstick 16PA6B STC diesel engines are the prime movers, powering four large Rolls-Royce Kamewa waterjets. Four Isotta Fraschini Model V1708 ship service diesel generator sets provide auxiliary power."
