Ilyushin Il-4
The Il-4 began life as the DB-3, being renamed in 1942 following a nose job. It had an impressive range, but with the exception of a few highly publicized raids on Berlin was used largely for more tactical efforts, like disrupting German rail traffic.
Cool stuff for Il-4 lovers:
There are not a lot of books in English devoted to the Il-4, but here is one: Bomber Pilot on the Eastern Front
