I build A CV and 2 Ftrs each turn. 3 tech rolls first turn (using AA50 tech tokens) netted me Jet Fighters  :-D.  By US4 I had 3 (soon to be 4) CVs outside SF with 5 Ftrs and a Tac.  2 CVs with 4 Ftrs in the Atlantic.  When I ramped up to 82 IPCs then comes the simultaneous transport build on both sides (more on Atlantic, KGF, imo) along with inf for a USA 5 or USA D-Day.  This way you ensure fleet support for your transports.  Learned my lesson a long time ago in AA50 when my opponent sacked his air force but completely decimated my D-Day fleet setting me back 3 turns.

I’ve also considered doing an Strat Bomber/Ftr build, but the new Alpha+1 rules kind of change that.  The idea would be to knock out Germany’s ability to produce frankly anything, along with killing the Luftwaffe exactly how the US actually did it: using the 8th Air Force to ‘escort’ (in quotes because they were really hunting the Luftwaffe) the bombers and take out the German fighters.  Haven’t tested this though cause it has 2 downfalls: longer time until USA gets D-Day going, and also practically leaves the USA in the dust fleet wise against Japan, which you CAN NOT do now with the new VC rules.
