Mitsubishi Type 1 G4M (Betty)
Technical Information

Background
Redefined Naval bomber operations because of its extremely long range. For comparison, RAF crews struggled 900 miles to Germany, Japanese Navy crews hauled similar bombloads to targets twice as far away in spacious, well equipped G4M1s.

Notorious for its tendancey to catch fire due to its large unprotected fuel tanks that tended to explode when hit by even short burst of enemy fire. Despite this shortcoming, it was one of the outstanding bombers of its time.
