and South Vietnam, first from bases at Udorn Royal Thai Air Force Base, Thailand from 31 March 1965 to 31 October 1967 and then from South Vietnam. These reconnaissance missions lasted from November 1961 through the spring of 1964. RF-101Cs flew pathfinder missions for F-100s during Operation Flaming Dart, the first USAF strike against North Vietnam on 8 February 1965. They initially operated out of South Vietnam, but later flew most of their missions over North Vietnam out of Thailand. Bombing missions against the North required a large amount of photographic reconnaissance support, and by the end of 1967, all but one of the Tactical Air Command RF-101C squadrons were deployed to Southeast Asia. The reconnaissance Voodoos at Tan Son Nhut were incorporated into the 460th Tactical Reconnaissance Wing in February 1966. 1 RF-101C was destroyed in a sapper attack on Tan Son Nhut AB. The last 45th TRS RF-101C left Tan Son Nhut on 16 November 1970. The need for additional reconnaissance assets, especially those capable of operating at night, led to the deployment of two Martin RB-57E Canberra Patricia Lynn reconnaissance aircraft of the 6091st Reconnaissance Squadron on 7 May 1963. The forward nose section of the RB-57Es were modified to house a KA-1 36-inch forward oblique camera and a low panoramic KA-56 camera used on the Lockheed U-2. Mounted inside the specially configured bomb bay door was a KA-1 vertical camera, a K-477 split vertical day-night camera, an infrared scanner, and a KA-1 left oblique camera. The Detachment flew nighttime reconnaissance missions to identify VC base camps, small arms factories, and storage and training areas. The Patricia Lynn operation was terminated in mid-1971 with the inactivation of the 460th TRW and the four surviving aircraft returned to the United States. On 20 December 1964 Military Assistance Command, Vietnam (MACV) formed the Central Target Analysis and Research Center at the base as a component of its J-2 Intelligence staff branch to coordinate Army and USAF infrared reconnaissance. On 30 October 1965 the first RF-4C Phantom IIs of the 16th Tactical Reconnaissance Squadron arrived at the base and on 16 November they began flying missions over Laos and North Vietnam. Farm Gate On 11 October 1961, President John F. Kennedy directed, in NSAM 104, that the Defense Secretary "introduce the Air Force 'Jungle Jim' Squadron into Vietnam for the initial purpose of training Vietnamese forces." The 4400th Combat Crew
