What I would do post 45.
I have,
2 x
Implacable-class - (better
Illustrious) best CVs ready in commission 1944.(32,630 t deep)
4 x
Illustrious class - heavy war use 36 design commissioned 40/41.(23,000 t standard)
1942 DLFCVs
- 10 Colossus class (2 as maintenance ships) 18,000 tons (full load) all new or finishing
1 x HMS
Unicorn commissioned 43 (20,600 t deep)
1 x HMS
Furious OLD !!!!
Building,
Audacious class 2 OTL lunched 46/50 37,000t standard.
Centaur class 4 finished OTL (53-59) 4 cancelled, 28,700 tons full load
Majestic class 6 ships 19,500 tons (full load)
So my plan (with a bit of crystal ball gazing.) would be to.
- Run the
Illustrious class into the ground (without much in the way of maintenance)
- Run the
Implacable-class with a bit more care (but nothing to expensive)
- Run the Colossus class until you sell them (they are cheap to run)
- Sell/scrap HMS Unicorn ?
- HMS
Furious maybe keep as a floating hulk so we can save her as a museum

.
- complete to replace the Colossus or sell the
Majestic class.
- Work slowly on completing the Audacious class to replace the
Illustrious class in 50-55.
- Work slowly on completing the Centaur class to run from 1950-55.
So in 55 you have,
2 Audacious + 2
Implacable (old now) and as many of the light fleets as you have not sold ( 4 Centaurs, few Majestic, less Colossus) some as repair platforms.
You then lay down 2 new bigger ships to replace the
Implacable class, keep the Centaurs
class and turn any remaining the Majestic/Colossus into helicopter LPHs.
Some time later (1965-70) you repeat (sell old ships off) and turn the older ships into LPHs (or sell and build some new cheap ones)
