The range isn't the most important thing for the missiles fired from the corvette, but by Norwegian doctrine, it is expected that Skjold class would work as an extended sensor and weapon guidance platform for the Frigates, trough Link 11 and link 16 communication system (Network warfare). (basicly ...

^just wondering, but does your corvette really need the ~370 km range of sm-2-ER (aka. sm-2-blk-4) ?

isn't the ~167 km range of sm-2-MR (aka. sm-2-blk-3) enough for the aaw config version ?

^based on the thales brochure for stir-18 (aka. stir-ik-mk2, 1.8m diameter antenna), it is rated for an instrumented range of 120 km and is advertised for use w/ essm... sm-2-blk3 (ie. present day sm-2-mr) engagement envelope is ~167 km (per: http://www.navy.mil/navydata/fact_display.asp?cid=2200&ti...

^is the main gun forward, and fcr aft (for NSSM), going to be re-installed ? (it's a quick/dirty edit right so I guess you'll be putting them back? ) the mini-STIR, the STIR 120, is an post cold war design (even post 2000 IIRC)... IRL, stir-12 (aka sting) came out in 1987, so yup it's not a fit for ...

I know the design is for an AU, but you may want to consider placing the aft stir-24 at the back of the mast facing to the rear... reason is that IRL, the perry's had a mod called "Missile System Engagement Improvement" done by JHU APL (john hopkins univ, applied physics lab) in w/c they tweaked the...

I was presuming the two Mk 92 mod 2 would offer two channels, and the pair of STIR-240s would offer one each, for 6. though I'm a bit unclear on some of the specifics. The problem appears to be, as you've pointed out, is that each CAS only contains 1 illuminator, even if two channels are offered. y...

^hmm, I don't know of any model in the wm-20 series or any mod in the mk-92 series w/c will offer 3 missile channels w/ the CAS+STIR combo... afaik it's always been 1 channel via the CAS tracker w/ cwi injection, and 1 channel via the STIR, so a max of 2 missile channels... --- there is an extension...

^acc. to friedman the sps-49 weighs in at around 1438 kg, w/c is pretty close to the sps-52 weight of 1454 kg... so why not just use the -52 so you get the 3d capability... w/ the 3d -52 set, the rudimentary 4-elevation band capab of the CAS search antenna is not needed anymore, and since you appear...

fwiw, acc. to friedman's book on naval radar, the original cut-cylinder sps-39 antenna weighed around 1363 kg, while the sps-48 (non-E version) planar array antenna weighed around 2045 kg... so around 682 kg weight diff... sps-48E weighed even more, at around 2583 kg... sps-52 (as well as the sps-39...
