I-69, later I-169, was an Imperial Japanese Navy Kaidai-class cruiser submarine of the KD6 sub-class commissioned in 1935. She served in World War II, during which she conducted six war patrols and took part in operations supporting the attack on Pearl Harbor, the Battle of Midway, the Guadalcanal campaign, the Aleutians campaign, and the defense of the Gilbert Islands. She sank in a diving accident in April 1944.
Size: 344′ (105m), 1,400-ton
The dive
I scanned the wreck on Feb. 24th 2025
She is sitting upright at 144′ (44m). Corrosion and damage is extensive, so there are no dive penetrations. Depth makes this a technical dive.
