Post subject:  Karel Doorman class frigate replacement
I made a drawing of what I think can be a good replacement of the Karel Doorman class frigates for the Dutch Navy. I call it the Van Amstel class frigate. A modern frigate based off the Zeven Provinciën class FFG.

I think you're grossly underestimating how much space that gun needs

It certainly looks very good, though I agree with Thiel. Try the OTO 76?

the gun has enough space for his systems and the Goalkeeper is not mounted in the center of the hangar but to the side

I improved the original design and made a new version with RAM and NSM those will replace the Goalkeeper and Harpoons.

I like the design but if you try to represent the currently planned Karel doorman replacement's i dont think it matches with the plans. For a personal design its fine might be a bit out-dated would fit better in 2000 - 2010 period.

The information that has been made public so far is not alot but enough to work with:

Weapons
- 76 mm Sovraponte / 76 mm or 127 mm on the bow ( renders show 76 mm sovraponte, documents suggest 127 mm )
- 76 mm Sovraponte on the hangar
- 16 cells mk41 strike lenght for ESSM and prepared for VL-ASROC / SM-3 / Tomahawk cruise missiles. ASROC is a dutch wish, SM-3 belgian and Tomahawk option is planned to be reviewd in 2020.
- mk54 torpedo's, mk 46's will be replaced from 2020, likely mk54 in combination with ASROC.
- Harpoons are being replaced by a new system very likely the NSM (cooperation with Norway and Germany has been announced)
- Work has started on the studies/development for a High Energy Laser for future use.

Radars
- SMART-S is a old rotating system, Thales announced the set up a few days ago.
- Sea Master 400 (SM-400) will be the E/F-band 3D radar, in the basic the same radar as the Holland OPV and Karel Doorman JSS. In a renewed plate (more range?)
- Apar Block 2 will be the X-band multifuntion radar for low level seach and guidance of the ESSM and SM missile family.
- Likely other Imast systems will be placed in the new frigates (ESM, ECM, EO, IFF, Comms)

Latest release of the Imast for M-frigate replacement by Thales.

The top speed has been announced to be 25-26 knots, with Diesel-electric only. Gasturbines are deemed to expensive.
A very important detail to the new ships will be that the replacement for the Zeven Provincien class will be based upon the same design.
