The B-10 began a revolution in bomber design. Its all-metal monoplane airframe, along with its features of closed cockpits, rotating gun turrets, retractable landing gear, internal bomb bay, and full engine cowlings, would become the standard for bomber designs worldwide for decades. It made all existing bombers completely obsolete. It was also the first mass-produced bomber whose performance was superior to that of the Army's pursuit aircraft of the time.
This bomber looks kind of strange next to my OD and camo bombers!
