With some summerdays to spare I updated my homepage of my imaginary fleet

New section
light forces torpedoboats, monitors

new ships
HMS Smålands Lejon prepre dreadnought rigged turret ship of the line
HMS Snapphanen, torpedocruiser 1941
HMS Kronprinsessan Louise antiaircraft cruiser
HMS Äran, guided missile cruiser with talos missles
HMS Göteborg destroyer 1968

I would love some comments on the work

Great stuff, especially the old stuf. They look ugly (as they should look) while your art is as good as ever.
:-)

One thing: the links for the HMS Smålands Lejon and the HMS Snapphanen are the same (both links go to the Smålands Lejon page). :-(

I like Aran personally, reminds me of HMS Tiger. Unsure about the helicopters. Might be better to build an actual hangar like Tiger and remove the aft 152mm turret and Talos launcher. Surprising to mount both 40mm and 57mm guns. I'd have thought 57mm only.

I doubt the wing turrets on the AA cruiser can actually turn bit otherwise nice work!

I think they can... about 10 degrees or so... but I guess that's not enough for them to be fully effective.

I very much like the Torpedo cruiser, it is certainly a design which I might modify for Nordmark.

thanks.

correct link to Snapphanen

Secondaries:
I use the 57mm mount as a long range CWIS, similar to to outfit on HMS Halland. The 57mm M/50 has longer range than contemporary CWIS missles like the Seacat and is also affective against FIAC etc, all turrets has itsw own radar director (the "egg" radoms). the 40mm are mounted high and is almost exclusivly CWIS-mounts.

I think there will be no problems for the wing turrets to turn, I tired to take extra care of that problem when I made the drawing.

I fear that it won't make it. Testing it out, when I turn the turret 45 degrees and try to place it correctly onto the wing turrets, it will result in the rear of the turret overlapping with the superstructure.

Nice work Psilander! I like Aran the most, quite a powerfull ship.

Ok, Iwill work out the turrets somhow.

I planning her follow on, a late 1980s ship. Can you simulate a CoDaG ship with just the diesels and then put in the weight for gasturbines as misc weight, a just calculate with SS the amount of power needed for the desired speed?
