Service history
Upon commissioning, I-33 was attached to the Kure Naval District and assigned to Submarine Division 15 in Submarine Squadron 1 along with the submarines I-31 and I-32.[2]
First war patrol
The
On 26 August 1942, the commander of the Advance Force ordered I-33 and the submarines I-11, I-15, I-17, I-19, I-26, I-174, and I-175 to deploy to the south and east of San Cristobal to interdict American supplies and reinforcements bound for Guadalcanal.[3] At around midnight on 28 August, I-15 sighted what she identified as an American aircraft carrier east of San Cristobal heading south.[3] I-15, I-17, and I-33 received orders to pursue the aircraft carrier, but failed to make contact with it.[3] I-33 sighted a U.S. task force on 30 August 1942 but was unable to get into a position to attack it.[2]
On 10 September 1942, I-15, I-17, I-19, I-33, and the submarines
Sinking at Truk
On 26 September 1942, I-33 was at Truk tied up alongside the
A rescue operation began immediately.[2] A diver found I-33 on the bottom in 120 feet (37 m) of water and reported that some crewmen were still alive aboard the submarine.[2] Lacking the equipment necessary to try to save the crew, the 6th Fleet abandoned rescue attempts on 27 September 1942,[2] and an investigation of the sinking began that day.
Salvage and repair
On 30 September 1942, the
Nippo Maru departed Truk with I-33 under
On 1 April 1944, I-33 was assigned to the Kure Guard Unit.[2] Work on her — including the installation of radar and a radar detector — continued until early May 1944. I-33′s repairs were declared officially complete on 1 June 1944, and she was assigned to Submarine Squadron 11 in the 6th Fleet that day for work-ups.[2]
Loss
I-33 got underway from Kure at 07:00 on 13 June 1944 to complete her
I-33′s commanding officer and nine other men were trapped in the control room. With water rising in the control room, the commanding officer decided to remain aboard the submarine and drown, but he ordered the men with him to escape via the conning tower.[2] Eight reached the surface, where they drifted apart in two groups that made for shore separately.[2] Most became exhausted and drowned, only two of them reaching shore alive.[2] Thirteen other men were trapped in the forward crew compartment.[2] The lower hatch of the escape trunk jammed, preventing them from escaping.[2] After 12 of the men suffocated, the last surviving sailor committed suicide.[2] In all, 102 men lost their lives.[2]
A few hours after I-33 sank, fishermen found the two men from the control room who had made it to shore alive and took them to Mitohama, where they contacted naval authorities.[2] The submarine tender Chōgei soon arrived, picked up I-33′s two survivors, and headed for the scene of the disaster.[2]
On 14 June 1944, search aircraft found a
A salvage barge equipped with a crane arrived on the scene on 16 June 1944, but an approaching typhoon forced the Japanese to abandon all rescue and salvage efforts that evening.[2] No inquiry into the sinking took place because most of the officers assigned to the investigation were killed in action during fighting in the Mariana Islands in the summer of 1944.[2] The Imperial Japanese Navy struck I-33 from the Navy list on 10 August 1944.[2]
Final disposition
After I-33 had lain on the bottom of the Seto Inland Sea for nine years, the Hokusei Sempaku salvage firm began work to refloat her in June 1953.
