LOLz he sounds like Stingray before he was kicked from SPF. But this can be a good thing, because in a few years he will be as contributive as Stingray is now. ;)

Another similar project was theVosper Thornycroft Project Cerberus Stealth Corvette.

Perhaps the most interesting (although very unlikely to be built for the RN "as is") is the CERBERUS stealth corvette design. The 2000 tonnes, 116m long, Cerberus is designed to deal with the sub-surface, surface and air threats to both itself and vessels in convoy. Cerberus can be installed with the Mk41 Vertical Launch System which allows for the fitting of Evolved Sea Sparrow (ESSM) in lieu of Aster and extends the potential range of weapons that may be carried to include ASROC and the proposed vertical launch Harpoon. A mixture of systems including SeaRAM, a medium calibre gun and two 30mm mountings provides inner layer air defence.

Anmd a press release:


VT unveils next generation Trimaran design

19 September 2001

Vosper Thornycroft has taken its family of trimaran warship designs into the next generation with the unveiling of a 116 metre corvette tailored to the export market.

The new design updates the original VT trimaran corvette developed in 1995 and incorporates VTs unique experience in building the RV Triton Trimaran Warship Demonstrator for the UK Defence Evaluation and Research Agency (DERA).

This experience has made VT a world leader in trimaran warship technology and the knowledge has been harnessed in the Cerberus design, which is unveiled for the first time at the DSEI exhibition to be held in Greenwich.

Jon Beadon, VT Export Ship Sales Director, explains: Preliminary results from the trials programme currently being undertaken by RV Triton have supported the initial theory of the advantages of a trimaran hull over a monohull. We remain firmly convinced that trimaran hulls will play a significant role in the design of future warships and Project Cerberus places the latest platform technology within this exciting hull form.

In addition, VT has incorporated some of the advanced features of its Sea Wraith stealth vessel in the new trimaran design, particularly elements that promote a reduced radar cross section. VT has combined these advances with notable trimaran benefits that include savings in propulsion power, improved capability for helicopter operations and better seakeeping. Another innovative approach in warship design is the use of the latest podded propulsion technology.

The result is a fast, stealthy corvette with the capability of a larger destroyer or frigate. The ship is designed to operate in littoral waters and the advantages presented by the trimaran hull form extend further its operating potential, adds Mr Beadon.

The Cerberus design is characterised by a long and slender main hull that produces improved seakeeping and this is augmented by a high bow freeboard complimented by a VT fine form ram bow. The cross deck structure begins some 40 per cent of the ships length aft of the bow and the clearance of its underside from the waterline (sometimes called wet deck clearance) conforms with results obtained from model tests and the full scale RV Triton trials.

The principal structure is of steel whilst composite materials are to be used for the superstructure, masts and the underwater bodies of the side hulls. The latter are constructed in easily replaceable sections to eliminate corrosion and facilitate repair in the event of damage. The sections are also made impermeable to minimise any resulting loss of buoyancy.

Careful shaping of the hulls and reduced clutter of topsides fittings ensures a low RCS. Advances in integrated mast technology have enabled Cerberus to contain radio communications antennae within the main mast or embedded in the structure.

Infra-red sources are reduced by cooling main engine exhausts and directing them to atmosphere under the cross deck between the hulls, while the side hulls also help to mask IR produced by the main engines and generators.

An innovative approach to propulsion has been adopted with the use of Rolls Royce Azipull podded propulsors. These compact units permit the transmission of the required power without excessively long shafting and four units are installed two aft and two amidships each driven by a medium speed diesel engine. Wide separation of propulsion plants significantly increases the vessels survivability in the event of damage to one engine room.

Cerberus is designed to deal with sub-surface, surface and air threats to both itself and vessels in convoy. The helicopter plays a key role in this capability with typical types able to operate from the ship including NH-90 and SH-60 Seahawk. Provision is also included for the operation of UAVs.

The trimaran configuration permits the installation of the latest multi-function radars such as the Empar without comprising stability or performance. This means that Cerberus can exploit the capabilities of the Aster or Evolved Sea Sparrow families of missiles for more effective air defence. Cerberus is designed for the installation of the Mk. 41 Vertical Launch System, which extends the potential mix of weapons to include anti-submarine and anti-ship missiles. An inner layer defence, provided by a mixture of systems including CIWS, a medium calibre gun and two 30mm gun mountings enhances survivability against air and surface attack.

In addition to the helicopter, the anti-submarine warfare equipment fit includes a low frequency towed array sonar and anti-submarine torpedo tubes. Cerebus also carries a comprehensive electronic warfare outfit, including electronic surveillance measures and both active and passive countermeasures.

Trimarans are swiftly gaining credibility as a hull form for the next generation of warships. VT is using its unrivalled trimaran experience to take this theory one step further with a viable design that provides navies with a new alternative for their front-line vessels, adds Mr Beadon.

CERBERUS

Development


CERBERUS is the result of an evolutionary series of trimaran ship designs developed by VT Shipbuilding and experience gained in the contract to design and build RV TRITON, a unique 97m ocean going research, trials and demonstrator vessel which became operational in 2000.

Reduced ship motions and superior seakeeping ability in higher sea states are the principal attributes of the trimaran, making it an outstanding platform for helicopter operations with a capability beyond those of their monohull counterparts and which consequently makes the trimaran an ideal anti-submarine warfare (ASW) platform.

The CERBERUScorvettedesign exploits the advantages of the trimaran hull configuration combined with modern electronic systems to provide the capability of a larger conventional ship, but in a smaller displacement and more acquirable form.

Hull Design


The CERBERUS trimaran is characterised by having a very long and slender main hull in order to gain the maximum benefit of reduced powering through reduced wave making resistance; the required transverse stability being provided by a pair of long slim side hulls supporting the primary cross deck structure. Improved seakeeping results naturally from the long, narrow main hull and this is augmented by a high bow freeboard complimented by a VT fine form ram bow.

Stealth

Above water stealth in low Radar Cross Section (RCS) terms is achieved by careful shaping of the hull sides and superstructures into flat, facetted panels displaying common attitudes and angles in both azimuth and inclination. RCS is further reduced from advances in integrated mast technology, which has enabled the majority of radio communications antennas to be contained within the main mast or be embedded in the structure.

Propulsion

The very slender main hull of a trimaran necessitates an innovative approach to the design and arrangement of the propulsion system. Four Azipull units are installed- two aft and two amidships- each driven by a medium speed diesel engine. Considerable advantage is gained with this arrangement in that it permits a very flexible combination of engine use

Accommodation and Habitability

The desire today is for reduced deployment costs through low manning levels and CERBERUS has therefore been designed to be fully capable with a crew of 62, plus 10 training berths. The trimaran configuration, with its wide single level cross deck, permits high standards of outfit which, on a comparable monohull, could not be achieved.

Combat System

CERBERUS is designed to deal with the sub-surface, surface and air threats to both itself and vessels in convoy. The increased beam of the trimaran allows for a particularly spacious Combat Information Centre (CIC) and Bridge together with the installation of the latest multi-function radars such as EMPAR without compromising stability or performance.

CERBERUS has been designed to be able to install the Mk41 Vertical Launch System which allows for the fitting of Evolved Sea Sparrow (ESSM) in lieu of Aster and extends the potential range of weapons that may be carried to include ASROC and the proposed vertical launch Harpoon. A mixture of systems including SeaRAM, a medium calibre gun and two 30mm mountings provides inner layer air defence.

CERBERUS carries a comprehensive electronic warfare outfit, which includes electronic surveillance measures and both active and passive countermeasures. The effectiveness of this suite is enhanced by the stealthy design of the vessel.

Do not be confused by the captions in Ace's pics, they are not of Northrop Grumman, they are fromNorthrop-Ingalls.

Here is aNorthrop Grumman proposal, the Littoral Corvette and Multipurpose Corvette aka Saar 5B:

Still a wise and helpful thing to do, especially for a forum like this.
