Cost calculations:

Light displacement 1930 tons, less one half miscellaneous weight (500 tons) = 1430 tons cost to construct


- LSTs are built to special rules because of them being a mix of a freighter and a warship
- The miscellaneous weight of LST is halved into deductible and non-deductible (50/50)
- The deductible weight is taken of the ships light displacement and so building time and building costs
- Otherwise all normal building rules apply
- For scrapping LST only the reduced weight is used for calculation.
- Any landing craft carried aboard the LST shall be purchased separately under light craft rules

Nicely done, though it seems to be a lot of weight for radar - those weights might be more appropriate for a destroyer or light cruiser, methinks. Otherwise very good.

Quite possibly the weight reserved for electronics is overstated - it is something I can examine between now and the formal laying down of the vessels. An alternative could be to install sonar as well.

I'd see a good new sonar as a valuable addition, yes.

I'm curious to see some drawings of them

Hmm. Looks like a nice little design.

I think it will fill a niche role. It's not as capable as a full fledged fleet tender, but then, the demands of a flotilla of S-boats or R-boats are less.

The Blucher class large cruisers, Blucher and Von der Tann, require minor refit to bring them up to current standards. This will be accomplished in 1943, following the proposal below.
