Something I believe Barnes Wallace had a hand in design wise.

Could take a lot of thump and still get home, used not just as a bomber too.

Sea mine detonator, airborne radar and U-boat hunter too. In production from start to finish and used as a post war trainer also which goes somewhat towards proving the point that you don't have to just carry a massive bombload to be as useful as some other types.

Versatility being the watchword here.
