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.
