What about against a rocket-powered glide bomb? I would think that something meatier with a prox fuse would be beneficial in knocking fast targets down.

Quoted from "Brockpaine"

All of these ships have worryingly low stability - 1.04, 1.05, etc... permissible, but worrisome.

Also, it looks like the Hardtwald sim seems to have a bunch of ^ symbols which replaced all the decimal points, and some other awkward wingdings stuffed in here and there.

Quoted

Seems a bit light perhaps, unless my misc weight for similar items is too high for lifts, catapults and arrestor gear? Though I have simmed the steam catapults heavy as there is a lot of piping and 'stuff' and maybe an additional boiler too.

Quoted

Personally I'm not quite as comfortable ditching larger caliber AA weapons just yet, given the presence of glider bombs and proto antiship missiles in the near future.

Quoted

With current technology a glide-bomb is not a fire-and-forget weapon system, but must be steered to the target under visual control by the aircraft which launched it. Kill the control aircraft and the problem is solved. That's if the electronic jamming of the flight control system hasn't already solved it.

More seriously, adjusting trim a bit so steadiness is at ~70% should help somewhat.

Quoted from "Rooijen10"

Okay, I did not know you went with converting existing designs, though looking at the "Deutsches Handelsmarine - Ship Designs", I am not sure why you went with such high steadiness ratings to begin with with some of those designs. With the Deutsche Werft Typ 3 Standard Oil Tanker that is not going to be much of an issue but with the Lubecker Maschinenbau Typ 1 Mehrzweckfrachter right below it, it has a steadiness rating of 100% while the stability is a mere 1.07 which is pretty poor compared to the 1.95 of the tanker. So it is going to be a bit of an issue when you are going to convert merchant ships that have a low stability to begin with and at the same time a high steadiness rating.
