@MistaBiggs:
It MAY be possible IF:
Germany completely whips out U.K.'s navy (except the transport in the India Sea Zone) – this would require the use of the entire German navy and air force. This would stop U.K. from being able to build the carrier or the transport … and in turn – U.S.A. could only bring over the 1 fighter and the bomber (both would have to land in U.K.).
Just because Germany destroys the UK navy on G1 does not mean that the TRN and AC cannot be built on UK1. If after G1, Germany has 3-4 FTR and 1 BMB, I will still make the buy. 3-4 FTR, 1 BMB vs. 2 TRN, 1 AC, 2 FTR (plus any potential russian boats) is good enough odds for the Allies. Especially with the potential to hit several German aircraft…which will never be rebuilt. The Allies can always build another fleet the next turn.
The only time I will not build the TRN and AC on UK1 is if the entire Germany airforce is intact and All of the Atlantic UK and Russian boats are gone. This rarely happens.
