The I-169 Submarine was sunk during Operation Hailstone in 1944

This short article about the I-169 Submarine Wreck is to provide you with a few basic details about this Japanese World War II submarine I-169. This submarine is one of the many Truk Lagoon wrecks for scuba divers to dive in Chuuk Lagoon.

Truk Lagoon wreck I-169 submarine was sunk by American forces at Truk Lagoon during Operation Hailstorm in 1944. The I-169 submarine wreck is the only submarine in Chuuk Lagoon and was the Imperial Japanese Navy’s Kaidai-class cruiser submarine of the KD6 sub-class built in 1930.

Truk Lagoon is the name these Pacific lagoons and islands were named in 1944 when they were in Japanese occupation. However, the name of Truk Lagoon was renamed in 1990 to Chuuk Lagoon.

Scuba divers seem to use these two names synonymously. Whilst the correct name is Chuuk Lagoon, at the time these ship wrecks were sunk it was named Truk Lagoon.

The best way to dive Truk Lagoon is by a scuba diving liveaboard. You can check the latest and best deals on Truk Lagoon liveaboards using the following window:

The Scuba Diving Earth Luxury Rating (SDE Lux Rating) is explained on each liveaboard review when you click the “Discover Liveaboard” link, and is my own Liveaboard Luxury Rating I’ve assigned to all liveaboards. Choosing between liveaboards is helped by customer scores, and if you get stuck choosing between two or three liveaboards, where each one has a high customer score out of 10, you can use the SDE Luxury Rating to help narrow down your choice.

Think about it like using when searching for the best hotel. also use a customer score where each customer rates hotels out of 10. This is similar to the liveaboard customer rating, which is also rated out of 10. But let’s say you only like to stay in hotels rated 8 and above on, but you also want the hotel to have WIFI or parking, or to have a swimming pool etc. The features each hotel has is usually secondary to the score out of 10.

Inside I-169 Submarine in Truk Lagoon
On my second trip to Truk Lagoon in Feb 2019 I went inside I-169, the submarine in Truk Lagoon, Chuuk. I-169 is the only diveable Japanese Submarine in the world. It is a Kaidai type submarine and participated in the attack on Pearl Harbor. It was sunk due to operator error during a raid on April 4, 1944.

My advise is you don’t go inside the I-169 submarine wreck, as this could prove to be very dangerous. It’s probably as dangerous as cave diving, as you don’t have an easy exit route. Listen to the comments of Pete Peterson in the second video below.

As the first video was of the inside of the I-169 Submarine, here’s a video of the outside of the I-169.
