Really like this, it's quite fun. One small suggestion would be a separate CATOBAR CVF which I would imagine would be a bit more expensive to procure and operate, but I've no idea how much more.
Anyway, on to my fleet. This is what I came up with...
Asture Class x6 Unit cost=747 Total cost=4482 Unit ops=27 Total ops=162
Vanguard Class x4 Unit cost=1500 Total cost=6000 Unit ops=35 Total ops=140
Type 212 x4 Unit cost=300 Total cost=1200 Unit ops=10 Total ops=40
QE Class x2 Unit cost=3000 Total cost=6000 Unit ops=90 Total ops=180
Canberra Class x3 Unit cost=330 Total cost=990 Unit ops=42 Total ops=126
Type 26 x16 Unit cost=350 Total cost=5600 Unit ops=22 Total ops=352
Type 45 x7 Unit cost=800 Total cost=5600 Unit ops=20 Total ops=140
BAM Class x7 Unit cost=200 Total cost=1400 & Unit ops=3 Total ops=21
Hunt Class x13 Unit cost=10 Total cost=130 Unit ops=3 Total ops=39
Total Procurement Costs =£31402 m
Total Operational Costs =£1200 m
Though I found it a lot easier if I unilaterally decided that the treasury would independently fund the nuclear deterrent.
Asture Class x7 Unit cost=747 Total cost=5229 Unit ops=27 Total ops=189
Type 212 x4 Unit cost=300 Total cost=1200 Unit ops=10 Total ops=40
QE Class x3 Unit cost=3000 Total cost=9000 Unit ops=90 Total ops=270
Canberra Class x3 Unit cost=330 Total cost=990 Unit ops=42 Total ops=126
Type 26 x16 Unit cost=350 Total cost=5600 Unit ops=22 Total ops=352
Type 45 x8 Unit cost=800 Total cost=6400 Unit ops=20 Total ops=160
BAM Class x8 Unit cost=200 Total cost=1600 & Unit ops=3 Total ops=24
Hunt Class x13 Unit cost=10 Total cost=130 Unit ops=3 Total ops=39
Total Procurement Costs =£30149 m
Total Operational Costs =£1200 m
Oh, and there seems to be a spelling mistake on the fleet report for the Mistral.
