The I-169 Submarine

Truk Lagoon, Micronesia

The Japanese 6th fleet command blew up the I-169 with depth charges to prevent its being compromised by impending American invasion forces.

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.

Penetrating to the lower engine room requires special skill. It is here that wrench/spanner sets, mounted on both the fore & aft bulkheads, can be seen.
