Starting at 0345 hours, B-17 Flying Fortress bombers took off from Port Moresby, Australian Papua to attack Japanese carrier Shoho which was spotted on the previous day; they attacked at about 0800 hours, causing no damage. Meanwhile, US carriers made rendezvous with Australian cruisers to set up an ambush at the Jomard Passage east of Australian Papua on New Guinea island. Later in the day, carrier aircraft from both sides searched for each other without success; at 2000 hours, the two fleets were merely 80 miles from each other, still not detecting the other party. Elsewhere, the new Japanese seaplane base at Tulagi, Solomon Islands was completed.
