look a page further down, but the ship will retain these lines as they are. It is not a 2011 Stealth Cruiser, but a 1996 Cruiser concept with limited stealth features.

Im sorry but stealth ships where designed from 95' on.
Not 2011...
And ships designed in 95' till 00' doesnt have the stealth you use, no in the whole side.

But it could be updated and refitted.
Remember this is an AU, so technologies don't have to be exact.

True, I do not want to argue over this. This is a fictional time line, and this is the way it stays.

Not really. It's not impossible, but you'd essentially have to rebuild the entire ship for nly a modest reduction in RCS.

Just enclose the back, remove the 127mm for this.
Then enclose the front till the vls deck.
Then you got a nice reduction on radar cross section.

But yeah i forgot its an AU :*):-S

Global Operations & Command Cruisers
In 1995 it was announced that the Tromp class guided missile ships were to be decommissioned the end of the decade. As a result the Dutch naval command formed a commission to investigate the needs for a new class of ships, that could function all over the world and cope with the ever more emerging threat of air-attacks and submarines. Furthermore the ship had to have an estimated lifetime of up to 40 years with several upgrades.

In 1996 the commission, in cooperation with the Scheldt Naval Shipyard, presented the design for a Class of highly advanced ships, that could operate in every scenario and fulfill a command role in every fleet formation. Shortly after the Dutch naval command agreed on the design, and the final design was presented:
[ img ]
The ships' designers incorporated many lessons learned by the Royal Navy during the Falklands campaign, and the design includes what is now better known as stealth technology, which improve the ship's ability to evade and/or destroy anti-ship missiles. Furthermore, her all-steel construction provides good protection for her superstructure, while the Collective Protection System allows her to operate in environments contaminated by chemical, biological, or radiological materials.

The class was to be equipped with the new APAR radar, which was claimed to be the most advanced, most capable radar system in the world. The APAR (Active Phased Array Radar) by Thomson Signaal contains four active phased array antennas with 3200 modules each, which together provide a 360 degrees azimuthal coverage. Some other features of the system are multi-function capability, digital doppler processing, digital pulse compression techniques, graceful degradation and flexible waveform generation. APAR operates in I/J-band, which makes the radar an excellent sensor for the detection of sea-skimming missiles.
The APAR system has one main waveform generator, plus two additional waveform generators to provide missile guidance links and target illumination in the terminal phase of engagement. Each array can generate up to four beams for 16 simultaneous engagements and 30 SM-2 and ESSM missiles in the air. Instrumented range is 150km in air search and 75km horizon search with elevation coverage up to 70 degrees and a capacity to handle 250 tracks. Another revolutionary radar system is the Smart-L radar. This is a volume-search early warning long range air search radar which has been designed by Thomson Signaal. It is a derivative of the smaller SMART-S, using an LW-09 solid-state transmitter. It uses an 8.2m electronically stabilized antenna scanning at 12 rpm to an elevation of 70 degrees. SMART-L provides range, bearing, elevation, and target velocity on each scan. Low observable targets can be detected at 125km and a conventional target beyond 300km. Maximum instrumented range is 900km. The ADT track file can carry up to 1000 air, 40 surface and 32 jammer tracks simultaneously. SMART-L is integrated with the Scout radar for surface surveillance

The missions assigned to this class of cruisers are:

Primary:
* Anti-Air Warfare (to provide local area air defense of a task group against airborne targets, in particular against saturating anti-ship missile attacks).
* To provide a Flagship function for a Taskforce or a Flottilla.

Secondary:
* Anti-Surface Warfare (to provide a significant fire power against surface targets (other ships) by surface-to-surface missiles and guns as well as the multi-function shipboard helicopter.
* Anti-Submarine Warfare (to provide an anti-submarine defense by using a heavy ASW helicopter)
* Naval Fire Support (to provide fire support for amphibious landings using the 127mm gun)

The design was slightly influenced by the USN destroyers built during the time, but was more capable in every way. The weaponry of the ship shows clearly for which role they are being built:
-Every ship is equipped with a Bofors/Fox 155mm naval gun, capable of hitting targets over 50km away. The gun can only be used for surface targets though.
-A total of 112 vertical launch cells are carried, 64 on the forward deck, and another 24 on each side of the ship in the middle. The ship can launch a variety from missiles from this system. For instance the SM-2ER, the ESSM or TMS-11, Vertical Launched ASROC and cruise missiles.
-Another revolutionary concept from these ships is the Close-defense weaponry. Each ship is equipped with three Goalkeeper 30mm guns in a new stealth copula (one forward, two on the side). This is backed up by the British-designed SeaStreak missile system. Two of these systems are fitted forward and backward, and each carry 24 missiles.
-For anti-shipping roles the ships are equipped with a total of 12 Harpoon missiles, if needed they can also be refitted with the TMS-01/AGM-44 Spear heavy-anti-ship missiles. In this case only 8 missiles can be carried.
-For the role of anti-submarine warfare 4 MU90 torpedo tubes are carried, and the Vertical Launch System can also be equipped with ASROC missiles.

Displacement: 8,900 tonnes empty, 10,350 tonnes full load
Length: 161,2 meters
Beam: 22,4 meters
Draft: 6,3 meters
Machinery: 4 General Electric LM2500-30 gas turbines, two shafts, 100,000 total shaft horsepower (75 MW)
Speed: >30 knots (56 km/h)
Complement: 28 Officers, 31 Chief Petty Officers, 174 Enlisted Personnel
Aircraft carried: Two medium-sized helicopters.

Two ships were ordered in this configuration and the keel was laid down of both ships in January 1997

Air Defense & Command Frigates
As part of the 1995 fleet evaluation the future retirement of the L-frigates was already foreseen. So a fitting replacement
was sought after. This resulted in the design of the LCF, or Air-defense & Command Frigates.
These ships are being build as part of a tri-partite building program between the Spanish Armada, the German Marine, and the Dutch Royal Navy. Instead of the failed Horizon program which involved Italy, France, and Great Brittain, this program concentrates upon the Ship Platform and systems, rather than on combat systems and weaponry. The other ships being developed in this program are the Spanish F-100, with SPY-1 and Aegis combat system, and the German F124, wich also has the APAR and SEWACO combat system.
[ img ]
The name of "Frigate" for these ships is actually a misnomer: With a displacement of over 6,000 tons they are destroyers in all but name. When the first of the class enters service, it will arguably be the most advanced ship in this size in the world. The Royal Netherlands Navy has apparently sacrificed upgrades to some of its existing warships in order to provide some of the needed funds for this class of four ships.

In keeping with the general trend, the ships have extensive Stealth features designed into them. Their large slightly angled slab sides give them a bit of the look of the French Lafayette frigates, although the LCF design is considerably bigger and capable. Survivability has been a great concern in designing the ships, and they are subdivided into seven main compartments. When hit in one of these compartments ventilation, firecontrol systems, and power will still be available in the other compartments. In order to achieve this all neccesary systems have full-sized backups.

At first it appeared that the main engines for the ships would be the new Rolls Royce WR-21, which will also be deployed on the Royal Navy`s Type 45 Destroyers. Unfortunately the WR-21 was not available in time (apparently it won`t be available until 2007), so for now the main engines will be Rolls-Royce SM-1C 'Spey' gas turbines, which are a good design which unfortunately is getting on in years. However, when the ships were designed the engine room was designed with the WR-21 in mind, and there is room for these turbines. It is not unlikely that the ships will recieve the WR-21 later on in their operational lives, a move which would substantially increase fuel efficiency and raise engine power.
Secondary engines have always been two Wartsila diesel engines, and the engines drive two adjustable counterrotating propellors.

For sensors the design features the APAR system, which has been build and designed by the Netherlands, Germany, and Canada. This is a high powered Active Phased Array Radar, which is smaller, yet considerably more powerful, than the American SPY-1 phased array radar. It can track up to 250 targets at one time, and at the same time can function as a illumination radar for up to 16 targets (with 32 missiles in the air), removing the need for seperate illumination radars. Because of its relatively small design it was possible to locate the four APAR panels in a single structure high above sea level. In a move which cause some last-minute delays the Dutch decided to have the APAR mount redesigned, so that in the future the guidance equipment for Standard TBMD missiles can be fitted. The long range search radar is the SMART-L phased array 3D radar. This radar is not stabilized, but the emission-angle of the radar is adapted to the curent sea state and angle. It has a range of up to 400 km, and can track up to 1000 targets. Mounted above the APAR, at the very top of the ship is a Sirius long range dual band infra red seeker, with a maximum range of roughly 30 km. Mounted on the hull is a Atlas Electronik active sonar.

The ships, together with the GOC-Cruisers, are presented as the first line of naval defense against anti-ship missiles (diving, cruise, sea-skimming, supersonic) incoming at supersonic speed from any direction, highly manoeuvring, in all weather conditions and in a severe electronic warfare environment, as well as aircraft attacks. The main tasks of these ships are to provide a local area air-defense capability against airborne targets for a task-group, and to provide that same taskgroup with dedicated command facilities.

The missions assigned to this class of frigates are:

Primary:
* Anti-Air Warfare (to provide local area air defense of a task group against airborne targets, in particular against saturating anti-ship missile attacks).
* To provide a Flagship function for a Taskforce or a Flottilla.

Secondary:
* Anti-Surface Warfare (to provide a significant fire power against surface targets (other ships) by surface-to-surface missiles and guns as well as the multi-function shipboard helicopter.
* Anti-Submarine Warfare (to provide an anti-submarine defense by using a heavy ASW helicopter)
* Naval Fire Support (to provide fire support for amphibious landings using the 127mm gun)

The weaponry of the ship shows clearly for which role they are being built:
-Each ship is equipped with a Oto Melara 127mm GP naval gun, capable of hitting targets over 22km away.
-A 48cell Mk-41 VLS is carried to launch a wide variety of missiles. For instance the SM-2ER, the ESSM or TMS-11 and cruise missiles.
-Each ship is equipped with two Goalkeeper 30mm guns capable of firing 4,200 rounds/minute
-For anti-shipping roles the ships are equipped with a total of 8 Harpoon missiles, if needed they can also be refitted with the TMS-01/AGM-44 Spear heavy-anti-ship missiles.
-For the role of anti-submarine warfare 4 MU90 torpedo tubes are carried.

Displacement: 6,000 tonnes empty, 6,600 tonnes full load
Length: 144,2 meters
Beam: 18,4 meters
Draft: 5,2 meters
Machinery: 2x Rolls-Royce SM-1C 'Spey' gas turbines, 2x Wartsila 16V 26 ST diesels
Speed: >30 knots (56 km/h)
Complement: 32 Officers, 26 Chief Petty Officers, 112 Enlisted Personnel
Aircraft carried: Two medium-sized helicopters.

Medium Sized Multi-role Frigates
In 1995 it was announced that, next to the Tromp class guided missile ships, the 10 S-frigates (or Standard-frigates) would reach the end of their useful lifetime around the year 2002. A new ship was needed that could fully replace the S-frigates in every role, and could also operate as air-defense ships in a large fleet. By the time some shipyards in the USA designed a ship that was a development from the NFR-90, and was to replace the OHP class frigates in USN service, as well in some allied navies. However the Americans rejected the program, and the initial design was bought by the Scheldt in 1996, and was optimized for service in the Royal Netherlands Navy, with indigenous radar and weapon systems. In 1997 the final design was accepted by the Dutch Naval Command, and 10 ships were ordered.
[ img ]
The ships use the same radars as there little brothers, the M-frigates (which were built from 1989-1995), to allow for easier maintenance and costs reduction. Another feature is the more advanced stealth structure, which can also be found on the Global Command Cruisers. The first ship of the class was initially a test-bed for the Dutch-built TMS-01/RGM-44 Spear heavy-anti-ship missiles, but later on all ships were fitted with 8 of these missiles, drastically improving there overall anti-ship capabilities.

These multi-purpose frigates can be used in the anti-submarine, anti-aircraft or surface combat roles. Their armament reflects that. Their primary surface armament consists of two quad launchers for the RGM-44 Spear anti-ship missile, which has a range of 120 kilometres. Backing this up is a 127 mm Oto Melara gun, which has both anti-ship and anti-air capabilities. Air defence is provided by a 32cell Mk-41 vertical launch system, which can launch VLASROCS, SM-2s and Short-range SAMs. Two Goalkeeper system provides close-range air defence. It fires 30 mm rounds and can fire up to 4,000 rounds per minute, with a range of 200 metres to 3 km.
For anti submarine warfare, each ship is equipped with two twin torpedo launchers, firing Mark 46 torpedoes, the VLS can launch ASROC missiles; and carries two medium-sized helicopters.

The main tasks of these ships are to provide a local area air-defense capability against airborne targets for a task-group, and protection against enemy submarines.

The missions assigned to this class of frigates are:

Primary:
* Anti-Submarine Warfare.

Secondary:
* Anti-Surface Warfare (to provide a significant fire power against surface targets (other ships) by surface-to-surface missiles and guns as well as the multi-function shipboard helicopter.
* Anti-Air Warfare.
* Naval Fire Support (to provide fire support for amphibious landings using the 127mm gun)

Displacement: 5,400 tonnes empty, 6,250 tonnes full load
Length: 133,2 meters
Beam: 19,4 meters
Draft: 5,2 meters
Machinery: 4 General Electric LM2500-30 gas turbines, two shafts, 100,000 total shaft horsepower (75 MW)
Speed: >30 knots (56 km/h)
Complement: 24 Officers, 27 Chief Petty Officers, 162 Enlisted Personnel
Aircraft carried: Two medium-sized helicopters.
