Amberjack also damaged the transport ship Tenryu Maru and hit the large tanker (converted Whale factory ship) Tonan Maru #2, whose stern sank to the bottom of harbor. She was salvaged, towed to Yokohama and repaired. She was sunk later in the war by USS Pintado (SS-387).

Patrol 2

21 Nov 1942 - 11 Jan 1943

No sinkings

Patrol 3

26 Jan 1944 - 16 Feb 1944 (lost)

Unidentified Schooner, sinking reported by radio. USS Amberjack was lost on this patrol.

Current research credits Amberjack with sinking 2 ships, totalling 5,233 tons. She probably also sank an unidentified schooner of unknown tonnage on her her last patrol.

JANAC - 2 ships, 5,225 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 Amberjack with 2 ships and 5,233 tons sunk, plus one unidentified schooner.

SORG credits Amberjack with 4 ships and 28,600 tons sunk.
