Balabac Strait
On 1 February 2009, the U.S. Navy announced the discovery of "Flier" near the Philippines' Balabac Strait (). The discovery of a "Gato"-class submarine was made during an expedition by YAP Films, based in part on information provided by a survivor of the sinking of "Flier". Further research by the Naval History and Heritage Command revealed that no other submarine, American or Japanese, had been reported lost in that general vicinity. In addition, footage of the wreck showed a gun mount and radar antenna, both of which were similar to the same equipment seen in contemporary photographs of "Flier". The ship rests in of water.
