Nice catch OP, hadn’t seen that one mentioned before. I think its a decent move for the US to build an AB there. If/when the Sealion threat passes, SZ 119 could be a nice spot for the Brits to move a Canadian-built fleet with US fighter cover.
kdfsjljklgjfg’s point is well-taken, usually the US will bring a sizeable fleet. But with the VC changes in the newest rules, the US might have to do things on the cheap in the Atlantic just to avoid losing in the Pacific.
The US could “hide” their starting Atlantic transport up in SZ 122 on US1 or 2, and take Eire with it once war is declared, flying 3 fighters to Gibraltar the same turn. Next turn, UK can move its Canadian fleet, if any, to 119; then the US builds the AB and lands fighters. The US has all those forces to begin with, so a minimum of 15 could be spent in the Atlantic for the first few turns to get 3 4’s defending the west coast of the UK. Any Sealion threat pretty much kills this one though, the Germans will just amphib the planes.
