AAF Theater Key :
SW Pac ;
1 . Okinawa was a prosperous kingdom from 1429, an exporter to China of sulfur used to make explosives. Okinawa was invaded by Japan in 1609 and treated as a separate fiefdom.
2 . Laffey (DD-724) on radar picket station No. 1, in
a period of 80 minutes underwent 22 separate attacks by
32 planes. She was struck by six of them, suffered four bomb
hits and was continuously strafed. Her gunners destroyed at
least eight of the attackers. At the conclusion of the attack,
only four of Laffey's 20mm mounts were still firing. Her main
batteries were destroyed, and she was down by the stern, her rudder
was jammed, and she was barely able to make steam. She can be seen
today at Patriots Point Museum, Charleston, S.C.
