On this day in 1943, USS Gato surfaced to find an unexploded Japanese depth charge on the deck. Because the charge could not be rolled into the water for fear of it detonating, it was lifted into a life raft that had a slow leak and then placed in the path of a pursuing destroyer.

Berthed in the Naval Air Station Pensacola, FL, before a series of early aviation tests, USN armoured cruiser North Carolina had a catapult prototype installed on her afterdeck. Current status: Scrapped in 1930-32, lifespan of 27 years. September 1915.
