Sankyo Maru No. 3 (The only one identified of ten red-birck-carrying motor-sail vessels sunk by gunfire on June 16, 1945. None credited to Flying Fish in JANAC)

19 ships, 58,570 tons (three were small vessel often not included in sinkings, and not credited to Flying Fish in JANAC), but including Tokai Maru, whose sinking credit is shared with USS Snapper (SS-185) and USS Permit (SS-178) (JANAC credits Flying Fish and Snapper only). The unconfirmed sinking of the small vessel on Patrol 2 is not included, nor are nine of the ten motor-sail vessels sunk by gunfire on Patrol 12, June 16, 1945.

JANAC - 15 ships, 58,306 tons, including shared credit with USS Snapper (SS-185) for the Tokai Maru sinking. Note that the criteria JANAC used included all Japanese Naval vessels (although JANAC did not usually count warships less than 500 tons that were converted from merchant ships) and all Japanese merchant vessels of 500 or more gross tons known or believed to have been lost during the war. Differences between JANAC figures and current research are noted above.

Alden-McDonald credit Flying Fish with ships and tons sunk.

SORG credits Flying Fish with 30 ships and 93,600 tons sunk (SORG gave no tonnage estimate for 7 of the 10 schooners it credits her with sinking.)
