View of two captured Japanese submarines taken from a periscope off the coast of Oahu Hawaii, soon after the end of World War II. (U.S. Navy records of this footage state that the two submarines shown are of the RO-26 and RO-51 class, but this does not appear to be true based on observation of the images). The first submarine is unidentified. The second submarine shown in the periscope view is the Type AM Imperial Japanese Navy submarine I-14. Closer periscope view then shows I-14 painted on the side of the submarine tower. Large explosion as submarine I-14 is hit by a torpedo from the USS Bugara (SS-331). Japanese submarine I-14 is seen sinking slowly. Next shot shows Japanese I-400 class submarine in the distance, and then up close through periscope. This is likely I-401 or I-400. Final portion of clip shows view from surface of water as I-400 class submarine sinks, after being torpedoed. This is most likely the May 31, 1946 sinking of Japanese submarine I-401 by the USS Cabezon (SS-334), but could possibly be the June 4, 1946 sinking of submarine I-400 by the USS Trumpetfish (SS-425). A HO3S helicopter flies overhead as the I-400 class submarine sinks.
View of captured Japanese submarine I-401 during Operation Road's End. The boat is sunk as a target off Barber's Point, Oahu, Hawaii, on 31 May 1946. Closeup view of the I-401. Next, it is seen at some distance from the U.S. submarine, USS Trumpetfish (SS-425), as it moves away from the I-401. The Trumpetfish (unseen) fires two torpedoes, in succession, as it proceeds. The first strikes the I-401 just aft of the conning tower. A little later, the second strikes amidships. The I-401 is seen sinking, stern first.
Sinking of Japanese submarines during Operation Road's End in the Pacific Ocean after World War II. Japanese submarine I-400 (I-400, boat 5231) on the surface , off Barber's Point, Oahu, Hawaii. In a test of the Mark 10-3 exploder, the I-400 is seen being struck by three Mark 18-2 electric torpedoes fired from the USS Trumpetfish (SS-425). The torpedoes explode in rapid succession, raising columns of white spray and smoke.
Huge smoke and fire rising at Pearl Harbor, Hawaii. View of thick, black smoke rising. Water hoses directed at the fire. An ammunition explosion and fireball from the expanding oil fire is seen near the end of the clip.
View of a Martin JRM Mars floatplane, variant JRM-1, moored at dock at Pearl Habor, Hawaii. Naval ambulances back up alongside the docked plane to remove medical patients from the JRM-1 Naval Air Transport Service aircraft. JRM Mars floatplane taxiing away from dock and view as it takes off from the surface of the water.
View of green fields and Hawaii hills. Two U.S. Navy cruisers steaming out at sea. United States cruisers fire on convoy of Japanese ships during Operation Road's End, destroying the naval forces of Japan following the war. Smoke and fire rises from the Japanese cargo ship which is hit. Scene shifts to a huge fire with thick black smoke rising from a dock at Pearl Harbor. A massive ammunition explosion triggered by the fire is seen.
