This is the Eidsvold class destroyer for my Norwegian AU. There are five batches: Batch 1, Batch 2, batch 3, Batch 3A and Batch 4. Each batch has improvements over the other.
Batch 1 is armed with two Mk.26 missile launchers for SM-2 and a Mk.29 launcher for the Sea Sparrow. Anti-sub weapons are two Mk.32 triple torpedo tubes and two Kjeller KJH-2 Vandrefalk helicopters. The ship is mostly an aerial warfare destroyer with anti-sub warfare as a secondary mission. KNM Eidsvold was commisioned in 1979.
The batch 2 has some stealth features included. The batch 2 is armed with the Mk.41 VLS and with the extra weapons that goes into the VLS, the batch 2 is a multi-role destroyer capable of anti-air, anti-ship and anti-sub warfare. Two Phalanx 20mm CIWS has been added fore and aft. Improved sonar and sonar dome. Designed in the early 80s` and commisioned in 1983.
The batch 3 has a raised forward superstructure to accomodate four phased radar arrays. The batch 3 has open space between the forward and aft superstructure. The propulsion plant has been revised and the ship is two meters longer to accomodate the Kjeller KJH-3 Albatross helicopter. The stealth features has been improved over the two previous batches. VLS tubes has been increased. New sonar and sonar dome. Designed in the late 80s` and commisioned in 1992.
Batch 3A is an updated batch 3 with extra stealth features. The funnel out takes are trunked into the funnel, the Mk.32 is moved into the superstructure with retractable doors concealing it. The five inch gun has a new stealth turret. Designed in the early 90s`, the first batch 3A was commisioned in 1996.
The batch 4 is an Eidsvold class for the future. Estimated commisioning is between 2015-2020. The entire superstructure has been altered to make the rcs as low as possible. The ship has recieved a much more advanced sonar in a new sonar dome. The batch 4 has the all new Kongsberg 6"/60 Future Naval Gun System with extended range ammunition. The ship has new and much more advanced AESA radars in the huge radar tower above the brige. Since I wanted the ship to scream stealth, I just had to make a stealth helicopter as well. Heavily influenced by some concepts of the stealth version of the Blackhawk, I made a stealth version of the KJH-3 Albatross.
All of the batches except batch 4 has the Kongsberg 5"/60 gun.
Oh, and I do know that it is very difficult to see the resemblence between the batch 3/3A and the batch 4, it is built on the same hull with some modifications to reduce the rcs.
