The WM20-series 'egg' has been out of production since 1990.
no problem replacing it with something else, suggestion.
my idea was to use some parts that Navy's "Might" have in store from other decommissioned ships, but at the same time use of the shelf parts. That in hindsight, how would you see these ships fitted/equipped.
I have lately got bitten by the idea of ships, that are build to high end requirement, but are armed with either "whatever" a Navy might have in store from before. But at the same time use the latest "of the shelf" equipment.
so for example the powerplant could be:
- turbine of older design, where all bugs over the years since it was developed, have been fixed. (basically, using last generation equipment then the latest equipment)
- Diesel engine doesn't need to be of the latest design number.
(Fuel cost will always be the downside)
Other parts:
- use older but upgraded radar that give close to today's radar performance or use "of the shelf" radar.
- older gun in new cloths with a updated computer system.
- etc.
It sound funny and weird, but when you look it from the perspective "Getting a Navy, without going bankrupt buying them". Fuel cost will always be a problem... but that is up to those wanting the ship, getting it a little bit cheaper, but more costly in operation
or have an fuel efficient ship, but more expensive. And so many other things. save money in one area, use more money in a another area.
