*2 Feb 1943 : During the night five crew members and 11 Japanese soldiers attempt to blow up the wreck using two depth charges. The resulting explosion is too weak to destroy the wreck.
*10 Feb 1943 : The Japanese, still concerned about the possible compromise of their codes, try to destroy the I-1. Eight carrier Aichi D3A2 "Val" dive-bombers, escorted by 28 carrier "Zeke" fighters and 14 from the 2nd (later 582nd) NAG, bomb the wreck and hit her once near the conning tower. About one fifth of the I-1 still sticks out of the water.

The wreck partially protrudes from the water.Critical codes remained on board and the Japanese command tried unsuccessfully to destroy the boat with air and submarine attacks. The US Navy salvaged 200,000 pages of intelligence: code books, charts, manuals, and the ship's log. [ [http://www.combinedfleet.com/type_j1.htm Submarine Type J-1] ]
Postscript
Circa 1970: An Australian treasure hunter in search of valuable metals blew up the bow section of the "I-1". This caused much damage since live torpedoes were still inside. The bow section of the sub is still there, but split open. The front one-third of the submarine is destroyed but the remaining section is still intact. The "I-1" lies with her bow in 45 feet and her stern in 90 feet of water.
