USS Arizona Memorial Visitor Center Museum - Japanese Torpedo
Japanese Imperial Navy Type 91 torpedoes were normally dropped from 100 meters, diving to nearly that depth before leveling off and running to the target. The relatively shallow 40-foot depth of Pearl Harbor necessitated modifications to the torpedo design and attack strategy. Outfitted with wooden, breakaway fins, and dropped from 10 meters above the water by 40 Nakajima Type 97 attack planes, the aerial torpedo proved devastatingly effective. This torpedo was found accidentally in the early 1990's by a dredging company in the channel off Ford Island.
