Converting the Admiral class into strike carriers

If three Admirals became strike carriers, should Britain also convert the Courageous class and Vindictive to build a larger carrier force?

Probably not: the Admiral conversions would likely displace Courageous and Glorious. The much larger force would need an unlikely budget and revised treaty rules.

Three Admiral-class strike carriers would probably remove the incentive to convert Courageous and Glorious. Furious and Eagle could serve as fleet carriers, with Hermes and Argus in the smaller carrier roles imagined by the question. The full proposal for about ten carriers is judged unlikely to secure its budget. If it did, Washington Treaty tonnage rules would need substantial changes, particularly if the conversions predated the treaty. Such a force could support a vice admiral for carriers in the Home Fleet and a rear admiral in the Mediterranean. Those appointments and their staffs could produce future Sea Lords with carrier experience, strengthening the case for Royal Navy control of a larger Fleet Air Arm.
