Word of the Japanese operation prompted Admiral Brown to change the objective of TF ll's strike from Rabaul to the Salamaua-Lae sector. On the morning of 10 March 1942, American carriers launched aircraft from the Gulf of Papua. ''Lexington'' flew off her air group commencing at 0749 and, 21 minutes later, ''Yorktown'' followed suit. While the choice of the gulf as the launch point for the strike meant that the planes would have to fly some 125 miles across the Owen Stanley mountains — a range not known for the best flying conditions — that approach provided security for the task force and ensured surprise. | Word of the Japanese operation prompted Admiral Brown to change the objective of TF ll's strike from Rabaul to the Salamaua-Lae sector.
