its easy, start an existing bomber campaign which involves shipping strikes etc then your generated campaigns location will be something like C:\Program Files\Ubisoft\IL-2 Sturmovik 1946\Missions\Campaign\DE\dgen_f_stalingraddoe0\
open conf.dat

replace your flights planetype with FW_200C3U4

its a hack/semi solution but it worked...but I only tried it years ago
