At 10:55, "Lexington"s CXAM-1 radar detected the inbound Japanese aircraft at a range of and vectored nine Wildcats to intercept. Expecting the Japanese torpedo bombers to be at a much lower altitude than they actually were, six of the Wildcats were stationed too low, and thus missed the Japanese aircraft as they passed by overhead. Because of the heavy losses in aircraft suffered the night before, the Japanese could not execute a full torpedo attack on both carriers. Lieutenant Commander Shigekazu Shimazaki, commanding the Japanese torpedo planes, sent 14 to attack "Lexington" and four to attack "Yorktown". A Wildcat shot down one and patrolling SBDs (eight from "Yorktown", 15 from "Lexington") destroyed three more as the Japanese torpedo planes descended to take attack position. In return, escorting Zeros shot down four "Yorktown" SBDs. One of the survivors, Swede Vejtasa, claimed three Zeros during the onslaught (though none were lost).
