Captain walker, I’m not trashing this strategy, but wouldn’t an extra carrier for each power be more helpful, and give you more mobility for roughly the same cost? Although an English AB on Gib, and an American AB on Morocco sounds intriguing giving you a really good air def for your transport navies(s) it sounds very costly. I’m not sure how that helps you when you move to Norway or deeper into the Med though because you would be leaving the cover of those bases, and the Luftwaffe could hit you then.
I could see it helping though if you build your fleet(s) then next turn move to Gib and drop AB(s) on the same turn so you could get immediate air cover. You wouldn’t have to wait for a carrier built that turn to catch up, but you would still need to bulk-up the navy before you move towards your objectives so I’m not seeing a major benefit for spending 30 IPCs on AB(s). Sounds like you may be going light on your navy builds for protection of your transports, and are compensating with the AB’s but the cost of the ABs is what is causing the weaker navy builds to start with.
I guess it would help to shuck-shuck through Gib though needing fewer naval units to protect your ships off Gib. I can see this would hold off the Luftwaffe for some time as well so there are some pro"s and con’s to say the least.
