Japanese Submarine I-178 (I-78, until May 20, 1942) was a Kaidai-typecruiser submarine that saw service during World War II in the Imperial Japanese Navy. Commissioned on December 26, 1942, I-178 was a KD7 sub-class boat that sailed on just two patrols off the east coast of Australia during 1943, going missing sometime after June 17, 1943.
I-176, lead submarine of the class that includes I-178
The KD7-type Kaidais was 346 feet (105 m) long and displaced 1,833 long tons (1,862 t) when surfaced. The diesel-electric propulsion system provided a maximum speed of 23 knots (43 km/h; 26 mph) when surfaced or 8 knots (15 km/h; 9.2 mph) when submerged. The boats could operate for 75 days before resupply. The Armament consisted of six forward-facing torpedo tubes firing Long Lance torpedoes (with 14 carried), a 4.7-inch deck gun, and a 25-millimetre anti-aircraft gun.[1]
The submarine was built at the Mitsubishi Yard. She was completed in 1942.[1]
Operational historyedit
Assigned to Submarine Squadron Three of the Sixth Fleet, I-178 sailed from Japan on March 30, 1943, and reached Truk on April 7. Three days later, the submarine left to commence a patrol off the eastern coast of Australia, supporting sister boat I-177. At 18:45 on April 27, 1943, the submarine torpedoed the Liberty shipLydia M. Child, 90 miles off the coast of Newcastle, New South Wales. There were allegedly no casualties among the freighter's 62 crew, who were all rescued the next day. I-178 escaped despite multiple attempted bombing runs by a Catalina from No. 11 Squadron RAAF.[1]
She returned to Truk on May 18, but was ordered to sail again two days later, returning to the Australian coast. The patrol was initially uneventful, but after sending a routine radio signal on June 17, I-178 was never heard from again.[1]
Fateedit
On August 4, 1943, the submarine was declared lost with all hands. She was struck from the Navy List on 1 September.[1]
