The I-182 is completed at the Yokosuka Navy Yard, commissioned in the IJN and based in the Sasebo Naval District. The I-182 is assigned to SubDiv 11, SubRon 1. LtCdr Yonehara Minoru (former CO of I-156) is the Commanding Officer. 8 August 1943:
Departs Sasebo. 10 August 1943:
Reassigned to SubDiv 22, SubRon 3. 15 August 1943:
Arrives at Truk. 22 August 1943:
Departs Truk to patrol off the New Hebrides. 1 September 1943:
At 1055, Cdr. J. F. Walker's USS WADSWORTH (DD-516) arrives from Espiritu Santo as part of a hunter-killer group and commences searching on a north-south axis. At 1300, the WADSWORTH makes a strong sonar contact and drops a full pattern of 10 depth charges with 150-foot depth settings, but with negative results. The WADSWORTH's second attack develops into a stern chase. The submarine turns left just before the depth charges, set at 250 feet, are fired. The submarine continues on a southerly, then northeasterly course, creating wakes that adversely affect the sonar's reception. The WADSWORTH makes several runs without dropping depth charges, then fires a deep pattern, set at 425 feet. As the destroyer turns to clear the area, a huge bubble surfaces, but otherwise the results are negative. The fourth attack develops into a stern chase, with the submarine maneuvering to create underwater disturbances. After dropping 10 charges with a mean setting of 250 feet, the WADSWORTH turns east to open the range. A Consolidated PBY "Catalina" patrol plane reports an oil slick and debris just south of the last depth charge pattern. The slick smells like diesel fuel and is about 400 by 600 yards. Wooden debris is also seen at 15-38S, 166-57E, but the identity of the submarine that the WADSWORTH sank remains unknown.* 15 September 1943:
The I-182 is ordered to return to Truk, but fails to respond to the signal. 22 October 1943:
Presumed lost with all 87 hands off Espiritu Santo. 1 December 1943:
Presumed lost. 1943:
Removed from the Navy List.
*The I-182 and the I-20 were operating in the New Hebrides at this time and neither submarine returned from their mission. It is possible that the WADSWORTH sank one of them in this attack. Author/historian Kimata Jiro credits the WADSWORTH with sinking the I-182. Special thanks for help in preparing this TROM go to Dr. Higuchi Tatsuhiro of Japan. – Bob Hackett and Sander Kingsepp.
