Current research credits Albacore with sinking 12 ships, 50,911 tons (two were small vessels totalling 155 tons often not included in sinkings)

JANAC - 10 ships, 49,861 tons. 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 Albacore with 11 ships and 49,908 tons sunk (Cha-165 is not credited to Albacore).

SORG credits Albacore with 12 ships and 72,300 tons sunk, plus 6 ship damaged, 30,900 tons.

Wrecksite credits Albacore with 12 ships and 55,153 tons sunk.
