ALASKA (Eleventh Air Force) In the Aleutian Islands, 40 P-40's fly 7 attack missions [2 by Royal Canadian Air Force (RCAF) pilots] against Kiska Island, bombing and strafing North Head AA batteries, the runway, Main Camp, and Little Kiska Island. HQ 343d Fighter Group transfers from Adak Island to Amchitka Island. The 406th Bombardment Squadron (Medium), 41st Bombardment Group (Medium), based at Elmendorf Field, Anchorage, Territory of Alaska begins operating from Adak Island with B-25's.
In the Aleutians, the USN's Task Group 16.21, consisting of battleships and cruisers, fights the "Battle of the Pips" off Kiska Island. Radar on the ships detected seven pips and believing them to be a Japanese force resupplying Kiska, all ships, except the light cruiser USS Santa Fe open fire. (USS Santa Fe had the most modern radar and saw nothing and she did not fire on the "targets.") A total of 518 14-inch rounds and 487 8-inch rounds are fired at the
"Japanese ships." Nobody has ever determined what caused the seven pips on the ships's radar.
The Japanese task group sent to evacuate the garrison from Kiska is actually 500 miles (805 km) southwest of Kiska refueling before dashing in to rescue the garrison. Because of the expenditure of fuel and ammunition fighting the "pips," the USN's TG 16.21 retires to refuel and rearm leaving the door open to the Japanese.

The Japanese try to hit US forces on Rendova Island but Allied fighters shoot down several Zekes (8 claimed) and force the enemy bombers to drop their bombs indiscriminately. The final push on the Japanese base at Munda opens with a bombardment by 7 destroyers and the heaviest air attack in the South Pacific (SOPAC) Theater to date; 170+ B-24's, B-25's, B-17's, TBF's, and SBD's, covered by 70+ fighters, pound the target thoroughly, dropping more than 145 tons of bombs in little more than a half hour; later in the afternoon 10 more B-24's, with fighter cover, bomb Bibolo Hill, and SBD's and TBF's dive-bomb gun positions; and later in the day, gun positions NE of Kindu Village are hit.
