@ Colombamike:

- The ship does have a crane, but i will add 1 larger crane
- 35 mm no good? ok will change it to 57 mm ( i did go out from a more ''standarized platform'' not specific swedish
- UAV capable? Yes VTOL UAV's and UAV's like scan eagle can be launched / recovered on the flight deck
- Sternramp? I can fit a small (2x LCVP or 1x LCU) dock with some Ro-Ro cargo space or just a large Ro-Ro deck with a steel beach ( the ship would need support from smaller crafts to unload the cargo )
- The ship is more a Long Endurance support platform for (example ) Operation Atalanta like operations she can support other combat units by its helicopters and hospital, but also take up a staff.

Let me get this straight. You want to apply stealth shaping to a ship that carries 40 by 9ft radar reflectors out in the open? (Otherwise known as containers.)
As for the whole ice thing, shrouded propellors aren't better protected, quite the opposite in fact since main danger comes from ice gettin jammed between the ship and the prop. A shroud just makes that jam more likely to happen since smaller pieces of ice can do the trick. Oh and you run into the very real danger of jamming the rudder since the shroud serves that function. That's why icebreakers don't us shrouds. If they get ice stuck down there they can use the props to break it up.

As i explained in my post above i wasnt going out for a ship to serve in the artics but for '' Minor Naval Powers'' not specific for sweden.
And the stealth isnt my design, for complains go to Damen Shipyards, they designed this shape.

Sorry, I was replying to mike but I must have deleted the entire quote.

Come on, this is uncalled-for... I don't see you participating in this challenge so not sure why you would call anyone's ideas "stupid". You have already been officially warned for this sort of behavior but for some reason I'm not surprised our warning did not seem to affect your thinking...:/

@ Thiel : ok no problem!

I will look at what i can do with the propulsion systems, and i will focus my ship upon ''Swedish Navy'' use ( or other Nordic navy's)

If you are not calling that bow not modern, then you are talking non-sens. Or Rolls Royce is wrong!!

The Idea Behind that bow is that it take what the X-bow is good at and ad it in to what an Ordinary bow is good at. BTW. Ulstein are buildinig X-bow ship with bulb.. eh. okay..!

Your CB90 isn't going to work via plug and play like that without major modifications to the stern to include a higher freeboard or an almost well deck like situation (impossible now as there is little to no underwater hull at the stern). The CB90 has an extra meter of beam, five more meters or length and probably another meter or so of height from keel to upper superstructure BEFORE adding in permanent sensor mounts over the SB90E that that those berths is designed to hold and service. Its also twice the displacement of the SB90E so your extendable gantry crane is going to need some serious beefing up.

Also those containers you have look small, are they standard intermodel? Even if they are they their number is almost not worth the effort as drawn, I think you could do some major reduction of the superstructure in that area given the weapon systems that were removed to make for a larger container capacity.

Hmmm,
A enlarged stern doors & a bigger gantry crane should do the job...
(from 6-9 tons for a SRC 90E to 17-22 tons for a CB 90HS)

The middle space is wide enough to receive containers...
