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

On September 20th, 2017, a team lead by noted award-winning explorer Tim Taylor discovered the remains of the WWII submarine lost in over 2600 meters (8500 feet) of water off the cost of Oahu, Hawaii.  

​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. She is the final resting place of 49 US sailors.
