RVN Made

The 4080th Strategic Reconnaissance Wing was issued the order to support the reconnaissance effort in South Vietnam.

Three detachments of 4028th Strategic Reconnaissance Squadron U-2E aircraft (#347, #370 & #374) were deployed to Bien Hoa AB to supplement the tactical reconnaissance being undertaken by the F-101s, initially known as "Lucky Dragon" then ‘Trojan Horse’, 'Olympic Torch', 'Senior Book' and finally 'Giant Dragon'.

The U-2’s began operations to gather intelligence on North Vietnam, which involved flying along North Vietnam and Chinese borders, generally gathering SIGINT, and also monitored the roads and trails from North Vietnam that were being used to send both weapons and personnel into South Vietnam and the surrounding states of Laos and Cambodia.
