Should the Dummonia not be called something like a "ASW Trials Ship" instead of a "Rotary-Wing Trials Ship"?

Good catch, forgot to change the title when I made the sim.

These hulls are over 20 years old now, and given the more modern requirements these ships could never really serve as modern vessels. After trials use they will be around 25-27 years old, not a bad service. A 25% refit at 15% cost is not expensive at all.

The G Class cruisers probably have another 5 years in them or so. The refits brush them up for modern use, but given their location next to China, these have the unenviable task of mopping up as many Chinese ships and aircraft as they can before they go down fighting to buy time for reinforcements to arrive. In a major war I do not expect them to last long, hence why the best ships are kept safe at Singapore. The poor old Improved Es are really Great War-era ships with some 1930s frills.
