Pe-2, Wellington or Beaufighter.EDIT:Or PBY-5
Pe-2, Fw-200.
Fw200 had little impact on the war, even at its peak effectiveness early in the war in the Atlantic.
As far as I know, the convoy hunting was the biggest threat the UK faced during the war, as said by Churchill himself. The Condor was widely used to spot those convoys, which would later be hunted down by U-boot wolfpacks. Some argue that the PBY sunk a lot of tonnage, but we can't forget that german u-boots alone sank almost three times the tonnage sunk by all allied countries. And a lot of those ships whent down thanks to airplanes like the Fw-200. It was ultimately replaced by some versions of 88s, 290s and 177s, but it set the first stone. That's why I consider it important.
No direct effect on the war, but a game changer in the game.P-51A and Mustang Mk.Ia Faster than B or D below 8k, lighter and more maneuverable. The Mk.Ia has four hispanos...
