No Sinkings

6 ships, 27,713 tons sunk - one (Banshu Maru No. 17) was a small vessel often not included in sinkings)

JANAC - 5 ships, 27,332 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 Pampanito with 6 ships and 27,713 tons sunk.

SORG credits Pampanito with 13 ships and 51,100 tons sunk.
