USA : SBD-3

A carrier-based dive-bomber/reconnaissance aircraft.
The most well-known U.S. Navy bomber, and perhaps the most significant dive-bomber of the war. Despite the fact that the decision to write off the SBD as outdated was made before the war, the bomber was still actively involved in combat, and in 1942 it sunk more enemy ships than all other Navy aircraft combined.

The SDB-3 variant was a Scout Bomber which was finally fit for combat. It had self-sealing fuel tanks, armor, and bulletproof cockpit glass. To keep its performance characteristics, the aircraft’s weight was reduced by replacing its duralumin sheeting with a much lighter material. Also, all equipment designed to keep the plane afloat in the event of a water landing was removed.
