Post subject:  Eidsvold class destroyer
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.

Hmm... The first one is... too stealthy, for 1979. And you have too small amarment for this ship. You only have a Mk-26 launcher, one guidance radar for both SM-2 and "Sea Sparrow".

And yeah, if this ship is primary a anti-ari warfare - why does she need TWO helicopters in hangar?

Too stealthy for 1979, maybe. Look at the top of the aft mast, there is a director for the Sea Sparrow. Two helicopters for ASW, SAR, cargo drop and troop insertion/extraction. Are two helos too much for that?

Colleague, for the primary anti-air destroyers of this era, two helicopters is too many. Maybe you better place only one helicopter, and add a second Mk-26?

You mean a hangar a la Spruance/Ticonderoga?

Yup. I just think that the anti-air destroyer... well, it must be primary anti-air! You have Mk-26. They can fire the ASROC. So, you really didn't need a big helicopters compartment for self-defense...

P.S. One question - for what direct purpos were those destroyers build by Norway in your AU? To impress the soviet naval aviation near Murmansk air bases you definitely need more AA systems than single Mk-26 and Mk-29!

Their mission was to protect other ships against planes, and later missiles. According to my idea, frigates are for escort of low-priority assets and anti-sub warfare. Destroyers are for anti-air, anti-sub warfare and escort of more high-priority assets. Cruisers are there for anti-ship warfare. All of these ships have a secondary anti-sub mission.

Hmm... In 1979, the missiles isn't "later". Especially if your potential opponent is USSR North Fleet,due to his Tu-16 and Tu-22 with AS-5 Kelt, AS-4 Kitchen under wings.

Ok, it's logical.

It may be logical for Norvegian navy, but don't forget about impressive soviet missile boat and naval aviation bombers fleet.

Which is why the cruisers can also have two, four tube box launchers for anti-ship missiles and have all the VLS for SAMs to shoot down the missiles and/or planes. I am working on a cruiser with the same radars as the Eidsvold Batch 3/3A. It will have as many VLS as the Ticonderoga. Imagine every one of them with SAMs. Or every one of them with anti-ship missiles, this missile fit would make it much more powerful than the Slava, but weaker than the Kirov. With full SAM loadout, the cruisers can cover a large area and shoot down a lot of planes.

In theory, colleague, in theory. I don't sure, that the 1980-th AEGIS system could actually stop a volley of supersonic sea-skimming cruiser missiles, approaching from different direction with ony SM-2 and "Sea Sparrow".

And, of course, your cruiser will be VERY expensive. Does the Norwegian navy really need this ship? It can't help anyway, to defend the north Norway. To beat the soviet navy near Murmansk, in the range of Russia land-based aircrafts... you need A REALLY BIG carrier armada, anyway! I really doubt, that even the USN will make thisi attempt except that in the final stages of the war.
