Except for a fuel run to just before midday, "Bunch" remained at anchor off Okinawa on the 15th. However, she received a report of enemy aircraft in the vicinity at 1830 and went to battle stations. Opening fire with her 5-inch and 40-millimeter battery, she join a barrage of fire that splashed an enemy plane off the beach. Securing from general quarters at 2000, she again manned battle stations an hour later; and sporadic enemy air activity kept her on alert until 2220. Air attacks on Yontan airfield, however, continued throughout the night.
