Any Comments?

Heh, of course there are comments....

On Stockholm, you can probably get some strength back by going to a transom stern. The range is exceptionally long, though to be fair Nordmark does have some relatively long distance runs, but still..... The 20mm mounts seem wrong: 10 single mounts, all aft on the centerline???

On the 31 class destroyer leaders, they look pretty solid, if perhaps a touch slower than some. Solid gun armament, you might want to raise the stem a bit to keep the water off the bow and you've got the extra strength to do it.

On Orn, another case where you might want to raise the bow, though if the flight deck is raised above the bow it's a bit less of an issue. The range, if they're to be paired with the Stockholm class ships, might need to be raised a bit.

Atualy there is lots of CVL sailing the seas of wesworld if there ever is a war there will be lots of aviation fires...Mmm aviation fires.

How do You plan to put 60 planes on such a small hull 40-50 is more plusible.

Doh!!!!!! Those mounts are listed wrong, I'l get that changed. Using a transom is not seen as useful on this design. As for the range, the excess allows for these ships to steam at speeds greater than 15knots for a greater length of time.

The speed of the follow on class will be greater. I think that the seakeeping of these ships is good enough, considering their size and speed.

The Flight deck is raised above the bow. The range of these ships isn't great, but is the best that can be expected, and is still enough to reach South Georgia travelling non-stop.

With Manzo still alive, that is a worry in Peace time. I Believe 60 planes is plausible on a ship this size, especially as the Russians are fitting 60 onto a ship 3000tons smaller.

The 60 aircraft comes from the 3600 tons of miscellaneous space, which when you take the square root of it you get 60. The WW rules say that aircraft take up (#aircraft * #aircraft) tons of space (or 25 tons per aircraft, whichever is more).

Stockholm, Lahti

Still not sure what the purpose of the end belts is, other than splinter protection (or national characteristic). With the relatively long main belt, sufficient buoyancy should be protected to keep the ship afloat and functional even if some compartments fore and aft of the citadel are full of water.

On Stockholm, it's a fairly blocky, broad design for a cruiser, with a BC of 0.55. Orn is just the opposite, with a BC of only 0.45. I might suggest meeting in the middle on both design, around a BC of 0.5 or perhaps a little higher for the carrier.

I don´t understand why there is an armored conning tower on the DD....?!

I don´t understand why there is an armored conning tower on the DD....?!

All the previous Nordish DD designs have them, so it wasn't a surprise to me.

2 ships built Orn & Falk
Can carry 60 aircraft

And the answer to the question about bc's is please check you've read the right sim. The Destroyer has a bc of .45

Hah, you're right, my question on the BC is a little off. Still a bit broad and blocky for a cruiser or a carrier, but not out of the question so. The Nords do tend to build their ships a bit blockier than some other countries anyway.

I was thinking more of the end belts on Stockholm, but the same question applied to Orn too.
