Late on the afternoon of 8 December, "Aylwin" followed the "Enterprise" task force into Pearl Harbor and picked up Rodgers and the division commander, CDR. R. S. Riggs, on the way into the channel. The next day, "Aylwin" got underway and conducted antisubmarine patrols in sector 2, off the entrance to Pearl Harbor. She made a sound contact on 10 December. After going to general quarters, she dropped a five-charge pattern, but with no confirmed damage. Entering Pearl Harbor again on the 11th, "Aylwin" underwent repairs to her damaged propeller.
