Thanks.

Based her dimensions on those of the USCG Cactus class buoy tenders, which in terms of Springsharp leaves her with a lot of extra strength. But that is a continual issue with smaller vessels, particularly if they don't carry a lot of armament.

Springsharp assumes anything you sim to be built to 'military' grade. I'm sure USCG ships are more robust than true 'civilian' ships, but no where near as stout as a true warship. Thinner bulkheads, less of them, thinner material of lower grade in the hull, etc. Here, there is extra strength because it assumes you're using heavier materials. Much like simming a wooden vessel, there will always be flaws in the sim.

One could also argue that the hull has been strengthened for ice navigation - which was, IIRC, part of the Cactus design. Still, they'll serve their purpose I think.

It is time for these vessels to be brought up to current standards in their electronic systems.

While I have been pretty exuberant in adding on a lot of radars, I have to wonder if 300 tons of radars might be a bit... much. Looking around at weights for historical radars and guesstimating weights for my own sets which are similar, I have to be especially profligate in both weights and quantity of radars just to reach 100+ tons.

I think the design could benefit from being scaled down to maybe as much as 75% of what it currently is.

I think the design could benefit from being scaled down to maybe as much as 75% of what it currently is.

Speaking of the weight provisions for radars you are, yes? ;)

Well, I think the entire ship could do the same job for about 75% of the tonnage.

You mean something nearer to this?

I think that's quite a lot better.

Well ships are getting more volume critical as we pile on the goodies. I agree the second ship is better, the first might as well have been a small CLAA. Which might be an idea to look at, given the hull space and the seakeeping and stability required for a good AA platform.

James, I think you have a good point there on an air defense cruiser, one that I shall have to consider. In light of that, I have made some further small economies in the proposed design; and here is Rev B.

I'm not a centreline torpedo carriage would work on that much beam. Maybe you'd want a more cruiser-ish torpedo layout?
