I-19 was a Japanese Type B1 submarine which damaged and destroyed several enemy ships during World War II while serving in the Imperial Japanese Navy. During the Guadalcanal campaign, with a single torpedo salvo, the submarine sank the aircraft carrier USS Wasp and the destroyer USS O'Brien, and damaged the battleship USS North Carolina.
On February 23, 1942, I-19 's floatplane made a night reconnaissance over Pearl Harbor, Hawaii in support of Operation K-1, a second attack on Pearl Harbor by the Imperial Japanese Navy. On March 4, she arrived at the French Frigate Shoals to serve as a radio beacon for the "Emily" floatplanes that were to attack Pearl Harbor. The "Emily" attack was canceled.
Sinking of USS Wasp and USS O'Brien
Three of the torpedoes hit Wasp, causing heavy damage. With power knocked out due to damage from the torpedo explosions, Wasp’s damage-control teams were unable to contain the ensuing fires, she was abandoned and scuttled.
The remaining three torpedoes from the same spread (torpedo salvo), often incorrectly attributed to a second Japanese submarine, hit the U.S. battleship North Carolina and the destroyer O'Brien, the latter of which later sank en route for repairs on October 19, 1942. Significant damage had been sustained by North Carolina, which underwent repairs at Pearl Harbor until November 16, 1942.
This single torpedo salvo thus sank an aircraft carrier and a destroyer, and severely damaged a battleship, making it one of the most damaging torpedo salvos in history.
From November, 1942, until February, 1943, I-19 assisted with the nocturnal supply and reinforcement deliveries, and later, evacuations for Japanese forces on Guadalcanal. These missions were labeled the "Tokyo Express" by Allied forces.
Between April and September, 1943, I-19 was stationed off Fiji. During this time, the submarine sank two and heavily damaged one Allied cargo ship. After sinking one of the ships SS William K. Vanderbilt on May 16, 1943, I-19 surfaced and machine-gunned the surviving crew members in their lifeboats, killing one of them.
On November 25, 1943, at 20:49, 50 nautical miles (93 km) west of Makin Island, destroyer USS Radford detected I-19 on the surface with radar. After I-19 submerged, Radford attacked her with depth charges. I-19 was lost with all hands in this attack.
I-19 in fiction
I-19 was the number of the submarine, commanded by Toshiro Mifune, in the Steven Spielberg movie, 1941. However, I-19 was off the Southern California coast in late 1941, along with a wolf pack of three other IJN submarines. On 25 December 1941, I-19 torpedoed the US freighter Absaroka off of Point Fermin, and the Asaroka was subsequently towed to and beached near Fort MacArthur.
