Club Fellow Discovers WWII Submarine USS S-28

One of the Top 10 Most Mysterious Shipwrecks of All Time —Outside Magazine 2017

On September 20th, 2017, a team lead by Explorers Club Fellow and Citation of Merit laureate Tim Taylor FN’04, carrying Explorers Club Flag #80, discovered the remains of WWII submarine USS S-28, lost in over 2600 meters (8500 feet) of water off the cost of Oahu, Hawaii.

Expedition S-28 was launched in 2017 to search for and document the USS S-28 (SS-133) S-class submarine, lost on July 4, 1944.

The current mapping and filming of the wreck by the discovery team is yielding valuable information that can help determine and possibly solve the cause of the sinking. ​Based on preliminary video and other documentation, the team currently speculates that the sub suffered a hull failure that resulted in the eventual separation of the bow, causing a near instant loss.

The data collected on this expedition is being shared with the US Navy Heritage Command. She is the final resting place of 49 US sailors. It is also important to share this news with the family members of the entombed sailors, and we encourage direct family members to contact the project at .(JavaScript must be enabled to view this email address).
