While patrolling over Guam at 0230 hours, 4 VF(N)-77 (USS Essex) F6F night fighters find that the Tiyand airfield on Guam airstrip is lighted, so they strafe the field until the lights go off. When at 0410 hours, the Tiyan airfield is again lit up, the 4 VF(N)-77 F6Fs shoot down 3 of 4 D3A 'Val' dive bombers that attempt to take off.
At dawn, Task Group 58.4 mounts aggressive fighter sweeps against airfields on Rota and Guam. From all appearances, the airfield on Rota is no longer operational, but opposition is encountered over the Orote airfield on Guam, where 18 Japanese Navy aircraft are shot down and 52 are destroyed on the ground.
Closing out the main portion of the Battle of the Philippine Sea, the 1st Mobile Fleet is able to remain beyond the range of all US aerial searchers—carrier aircraft launched from Task Force 58, PBMs based at Saipan, and PB4Ys based at the Momote airfield on Los Negros. Nevertheless, at 1540 hours, a VT-10 TBM finally spots the main body of the Japanese fleet, which is refueling well to the west of Saipan. An immediate strike is launched—54 TBMs (all but VT-28’s armed with bombs), 51 SB2Cs, 26 SBDs, and 84 F6Fs. At the extremity of their range and with only a half-hour of daylight remaining, the US carrier aircraft commence their attack at 1840 hours. Despite heavy antiaircraft fire and a defense mounted by an estimated 75 A6M Zeros, VT-28 TBMs sink the fleet carrier Hiyo with 1 or 2 torpedoes. The fleet carriers Junyo and Zuikaku, and light carriers Chiyoda and Ryuho are damaged by bombs, as are 3 fleet oilers. 4 TBMs, 10 SB2Cs, and 6 F6Fs are lost in this action, but—far worse—an additional 28 TBMs, 35 SB2Cs, and 17 F6Fs are forced to ditch when they are unable to land aboard friendly carriers after dark. All but 16 pilots and 33 airmen are recovered within 48 hours, but during the night, a VP-16 PBM based at Saipan is shot down by US destroyers while attempting to locate pilots and crewmen of ditched US carrier aircraft. All 11 men aboard the PBM are lost.
Though the balance of the Japanese 1st Mobile Fleet makes good its escape during the night, its surviving carriers have but 35 aircraft remaining aboard.
Throughout the day, US carrier pilots down 42 Japanese aircraft at sea, over the islands, and over the First Mobile Fleet.

| ]Battle of the Philippine Sea
The Japanese do not realize the extent of their losses and begin to withdraw temporarily to refuel. They believe that most of their aircraft have landed safely on Guam. Mitscher, of course, pursues and in the late afternoon sends 216 planes, high-level bombers, dive-bombers and torpedo-planes, to attack. They meet only 35 defending fighters and break through to sink the carrier Hiyo and damage 2 others, a battleship and a cruiser. In the action 20 American planes are lost. A further 72 crash in attempting to land back on their carriers in darkness despite the flight decks being bravely lit. A feature of the US operations in this and other engagements is the care taken of the pilots - only 16 flyers and 33 aircrew are not picked up and the story in the rest of the battle is similar. By contrast the Japanese have saved almost none of their pilots and although they still have a significant force of ships they cannot possibly train enough men to fly their aircraft. The pattern of all the previous fleet encounters in the Pacific is thus confirmed.
During the night the Japanese withdraw and are not followed. After this great victory by Spruance and Mitscher the Japanese realize that the outcome of the war is decided.

BURMAOn the Salween front, the Chinese 36th Division takes Watien in the Shweli valley.
Gen Stilwell and his NCAC (Northern Area Combat Command) force are transferred from operational control of the 14th Army commander to direct control of the Supreme Allied Commander. The GALAHAD situation is now critical because of battle exhaustion and disease, and it is apparent that Myitkyina cannot be taken quickly. Personnel from the rear area are forced to return to the battle when at all fit for duty.
CHINAVice President Henry Wallace arrives in Chungking, China, as President Roosevelt's personal emissary to assess the situation in China. Gen Stilwell is in Burma and unable to meet with Wallace. Chiang Kai-shek and Gen Chennault, however, are available for meetings and are more than willing to paint the gloomiest possible picture of events. They also press for Stilwell's removal in the interest of preserving Allied unity.

On Saipan the 4th Marine Division continues its sweep to the north, linking up with the 2nd Division.

As the 4th Marine Division swings around the 2nd, the 25th Marines encounters and reduces well-organized enemy positions on Hill 500, just west of Tsutsuuran village. The 27th Division begins converging drives on Nafutan from the north and west. The 165th Infantry, reinforced by the 1st Battalion of the 105th, attack to the south toward Nafutan Point at noon after preparatory fire and gains about 1,000 yards. The 3rd Battalion, 105th, continues eastward along the south coast for about 600 yards. It is then only about 100 yards from the 165th Infantry force. The 106th Infantry lands on Saipan and is placed in corps reserve. The 2nd Battalion, 105th Infantry, reverts to the 27th Division.
