Breathe Underwater

WWII Torpedo Bomber in use. Didn’t show up until the Battle of Midway and there were only 6 of them in use. Despite the loss of five of the six Avengers on its combat debut, it survived in service to become the most effective  and widely-used torpedo bomber of World War II, sharing credit for sinking the super-battleships Yamato and Musashi (the only ships of that type sunk exclusively by American aircraft while under way) and being credited for sinking 30 submarines. Greatly modified after the war, it remained in use until the 1960s
