Instead of all bombing done by one power, divert the cost across multiple powers (quite historic if you ask me). Even a sassy player like myself would consider a russian bomber if the cash flow is there.
If you get real crazy with NA’s…… lend lease can make this pipe dream(crack pipe off course) a reality. And forget about superfortresses - they wreck Germany every time.
But if and when the zitties start hitting (non-NA games), it is a large loss to the allies. Law of averages will eventually shoot down bombers as you throw enough of them at Gerry. The outcome from this is determined by how well you spent your disposable income after Bomber purchases. In all actuality, it would have to be a KGF tactic. Bring the entire US fleet around to the Atlantic, along with the latecoming British aussie fleet, and as they slowly feed into the game, you may be able to offset the german naval onslaught. I get the impression that if the allies do not feed all existing forces into Europe, Germany can offset some of the IPC loss with gains in Africa / Mid East / Russia combo and also the possibilty of an early and undeterred naval consolidation.
