The submarine left station and arrived at Pearl Harbor on 7 February, only 23 days after leaving Brisbane (most patrols were in the 60‑ to 75‑day range). Prior to entering the naval base, "Wahoo" donned topside embellishments to celebrate her victory. A straw broom was lashed to her periscope shears to indicate a clean sweep. From the signal halyard fluttered eight tiny Japanese flags, one for each Japanese ship believed to have been sunk by "Wahoo" to that point in the war.
