Truk Lagoon is a famous World War II naval site. During Operation Hailstorm, February 17-18, 1944, US forces inflicted heavy damage to the Imperial Japanese Navy (IJN) fleet stationed within the lagoon. Our sojourn to view the dive site began from Sacramento, California and transitioned through Los Angeles, a refueling stop at Hawaii, and an overnight stay in Guam, before continuing on to Chuuk Lagoon, as it is now called. Chuuk is part of the Federated States of Micronesia (FSM).

Dive sites

 

Our diving was conducted from the Thorfinn. The ship supported two dive boats from which all dive operations were conducted in the Eastern sections of the lagoon.

The following are the dive sites visited during our stay. Because of the depth of each dive and the sequence, up to four dives per day, each dive was treated as a decompression dive.

In researching the vessels that we dove, reference was made to a number of books. Two I found helpful in identifying artifacts and descriptions of the vessels are included below. To assist you in gaining a better idea of the vessels, both before and after their sinking, images were provided . Drawings of our dive sites were also provided from Thorfinn briefing guides.
