Three RF-100As were also deployed to the 6021st Reconnaissance Squadron at Yokota Air Base in Japan, but details of operations there are not available. Two RF-100A aircraft were lost in accidents, one due to probable overspeeding which caused the separation of one of the drop tanks and resulted in complete loss of control, and the other due to an engine flame-out. In mid-1958, all four remaining RF-100As were returned to the US and later supplied to the Republic of China Air Force in Taiwan.
