The I-169 Submarine

Truk Lagoon, Micronesia

While replenishing fuel & supplies in April 1944, a warning of an American air raid sent this submarine to the bottom to wait until the raid was over. The sub failed to resurface and investigation by a diver found a storm ventilation tube open and the control room flooded. Salvage operations failed and the entire crew perished. The Japanese 6th fleet command blew up the I-169 with depth charges to prevent its being compromised by impending American invasion forces.

According to Klaus Lindemann's Hailstorm over Truk Lagoon guide, "points of interest on this ship are: aftship with conning tower sagged to port. Cables forward were part of degaussing device. Large double exhaust systems, two access hatches, tripod mast.

This passenger/cargo ship sunk upright with a 15/20 degree list to port. The vessel was under repair at that time & there is little to be found in the holds.
