Thanks - Badger1968 for the 'plans' impressive.
I can see some other early possibilities - following on from my early post (24) - with a big convoy what if one of the CVLs is with the Convoy escorted by Jervis Bay when the Scheer comes a-calling ..... ? And even later, when Bismarck is loose - could two or three with different Convoys converge .... !!?
Although these CVLs couldn't survive in a high threat area like the Med., it's IMHO interesting the flexibility they would give the RN.

If this doesn't meet authorize use guidelines; please let me know and I will take it back down.
Drawing doesn't quite match the model....
HMS Argus has 15-18 on ~15k tons std, so 10-12 on 10k std?
HMS Vindictive's hull is slightly longer, ~same beam, therefore much finer - so no ability to effectively use the ends.
The other issue is the ability to store petrol to RN standards in any volume in such a fine hull.

Again thanks for the interesting info: - a few things occur to me,
- If it was on the RN's agenda to do these conversations, it's possible the British Delegation could have been primed to aim for a higher figure than originally stipulated under WNT, maybe unlikely, but not impossible!
-In the other conversion the weight went down, e.g. Glorious Class LBCs 22,700 tons, as Aircraft Carriers 18,600 tons, HMS Furious (as designed) 22,900 tons, A/Carrier 19,100 tons, and HMS Erin (sister ship of Almirante Cochrane) 25,250 tons, HMS Eagle 22,600 tons.
- With the experience gained be these early CVLs, and the prospect of aircraft getting bigger compared to the aircraft of the early thirties, it could lead to the Unicorn & Colossus CVLs being designed and built earlier!!?

Converting Vindictive to a full-deck carrier would almost certainly have included adding bulges - not only for added stability but also for fuel oil storage (she would certainly have converted from coal to fuel oil at that time instead of in 1929) allowing aviation fuel to be stored in interior fuel oil tanks placed in the former coal bunkers). Any further conversions would be after that time, as until the late 1920s this class was the RN's most modern and powerful cruiser class.
2. Adding those bulges would have raised her standard tonnage from 9,750 tons to ~11,000 tons - so she would indeed be counted in carrier tonnage even under WNT. It would also have dropped speed to ~28 or so knots.

If RN was planning to convert Vindictive into a full deck carrier; wouldn’t the decision have occurred before WNT, so Vindictive could be included in the ”experimental” carrier group? She is as much a CV as Furious in ’22...
I can’t see RN changing policy and incorporating huge number of planes onto Vindictive, just because they have built a full deck. HMS Hermes only operates 20 a/c and this ship is ~80% size of Hermes. And we know carriers are volume constrained, so Vindictive won’t even operate an air group that large. Plan around 12-16 a/c per Vindictive class CVL.
I can’t see Effingham completed as a CVL – historically, she was completed as CA using salvaged equipment from Raleigh to maintain cruiser numbers. In ’25, cruiser is more important than carrier. Also, the full deck plan referenced in Hybrid warships has HMS Vindictive maintaining 5-7.5” mounts, that’s why she is in the book, so you might not recover enough weight to keep her below 10k.
aground 6 July 1919, seriously damaged, repaired at Portsmouth
Dockyard and laid up in reserve 24 December 1919 following completion
of repairs. Briefly recommissioned in 1920 as a troopship.
Reconverted to cruiser
1 March 1923 to 3/1925. Retained a small hangar and catapult forward
up in reserve 1929; demilitarized under the London Treaty 5/1937,
recommissioned as a training ship 7 September 1937. Converted to a
repair ship in
1939. Decommissioned for disposal 9 September 1945. Sold 24 January
1946 and subsequently scrapped at Blyth.
