Around 14:30, Hara informed Takagi that only 24 Zeros, eight dive bombers, and four torpedo planes from the carriers were currently operational. Takagi was worried about his ships' fuel levels; his cruisers were at 50% and some of his destroyers were as low as 20%. At 15:00, Takagi notified Inoue his fliers had sunk two U.S. carriers – "Yorktown" and a "-class" – but heavy losses in aircraft meant he could not continue to provide air cover for the invasion. Inoue, whose reconnaissance aircraft sighted Crace's ships earlier that day, recalled the invasion convoy to Rabaul, postponed "MO" to 3 July, and ordered his forces to assemble northeast of the Solomons to begin the "RY" operation. "Zuikaku" and her escorts turned towards Rabaul while "Shōkaku" headed for Japan.
