Making a virtue out of necessity ships can be withdrawn for refit.

Assuming the RN wants something close to new build;

Hurricane bows and a full length, flat flight deck,

30+ kts speed,

8 x twin 4.5” HAA , 6 x octuple Pom pom, 4 x 0.5” LAA,

Armoured box hanger,

36 a/c.

What's possible on the hulls might be;

Hurricane bows and a full length, flat flight deck,

30+ kts speed,

8 x twin 4.5” HAA , 6 x octuple Pom pom, 4 x 0.5” LAA,

c54 a/c in a slightly bigger hanger.

What's possible with 1940 shortages might be;

Hurricane bows and a full length, flat flight deck,

30+ kts speed,

Fitted for but not with 8 x twin 4.5” HAA , 6 x octuple Pom pom, 4 x 0.5” LAA, refitted with;

Furious ; 6 x twin 4”, 4 x octuple Pom poms, 4 x single Pom poms, 1 x quad 0.5” with whatever additional LAA can be found,

Courageous; 16 x single 4.7”, 3 x quad Pom poms, 1 x quad 0.5” with whatever additional LAA can be found,

Glorious; 16 x single 4.7”, 3 x octuple Pom poms, 1 x quad 0.5” with whatever additional LAA can be found,

c54 a/c in a slightly bigger hanger.

How long might each refit take and in what order would be best?
