Game hasn't been going on very fast and not much happening between these turns anyway. Here's a few 'highlights' though.
On turn 45 spotted some US transports with very few escorts. Turns out Allies have been busy building several subs... wonder how that plays out. Also, on turn 47, last British forces at Scapa Flow fortress surrender... finaly.

Research situation on turn 49:
And the preparations for Barbarossa '42 on turn 49...
