Combat Air Patrol: June 1944 Saipan

What's going on here? USS Manila Bay, a US Navy escort carrier with a deck load of US Army P-47 fighter planes, attacked by Japanese aircraft east of Saipan on June 23, 1944. The story gets better. Here is what the Dictionary of American Naval Fighting Ships says:

"On 7 May 1944 MANILA BAY sailed for overhaul at Pearl Harbor, where she arrived 18 May. After loading 37 Army P-47 fighters, MANILA BAY sailed 5 June for the Marianas. Steaming via Eniwetok, she reached the eastern approaches to Saipan 19 June. During the next four days she remained east of the embattled island as ships and planes of the Fast Carrier Task Force repulsed the Japanese Fleet in the Battle of the Philippine Sea, and inflicted staggering losses on the enemy, thus crippling the Imperial Japanes Navy's air strength permanently. On 23 June, MANILA BAY came under enemy air attack during refueling operations east of Saipan. Two fighter-bombers attacked her from dead ahead, dropping four bombs which exploded wide to port. Intense antiaircraft fire suppressed further attacks, and as a precautionary and rather unusual move which Admiral Spruance later characterized as "commendable initiative," MANILA BAY launched four of the Army P-47s she was ferrying to fly protective CAP until radar screens were clear of contacts. The Army fighters then flew to Saipan, their intended destination. She launched the remaining planes the next day and returned to Eniwetok, arriving 27 June. After embarking 207 wounded troops, MANILA BAY departed 1 July, touched Pearl Harbor the 8th, and reached San Diego 16 July 1944."
