Detachment H resumed overflights of mainland China in December 1962, but its missions now concentrated on the southern portion where there were fewer radars and SAM sites. During December 1962 and January 1963, the detachment conducted two successful overflights of Sichuan, but a mission over south China had to be aborted prematurely. The results of Detachment H's continuing coverage of the People's Republic of China remained of considerable interest to the United States. On 17 December 1962, the Special Group approved plans for fiscal year 1963/64 that included requirements for photo coverage of mainland China and for maintaining at least two operational U-2 aircraft in Detachment H. $ ^{44} $
## Use of Detachment H Aircraft by US Pilots
Detachment H's importance did not lie solely in the missions carried out by its Nationalist Chinese pilots against targets in mainland China; the detachment also provided aircraft for use by American pilots flying missions in other parts of Asia. Indochina was an area of particular interest as American involvement there began growing during the early 1960s. Beginning in February 1962, Detachment G pilots went to T'ao-yuan to use the unmarked Project TACKLE U-2 for overflights of North Vietnam. During the first half of 1962, Detachment G pilots made seven overflights of North Vietnam from the Tao Yuan base. Thereafter, Detachment G pilots could use their own aircraft because the unit began staging teams and aircraft from Edwards AFB to Ta Khli AFB in Thailand.
Between 1962 and 1964, Agency U-2s staged a total of 36 photographic missions over North and South Vietnam. By April 1964, however, photographic requirements were changing from strategic reconnaissance to tactical support as the Viet Cong became more active, taking advantage of the weakness of the South Vietnamese central government following the coup that overthrew President Ngo Dinh Diem in 1963 and subsequent coups by disgruntled army officers. During this period the South Vietnamese "strategic hamlet" concept began breaking down, and the Viet Cong forces stepped up the pace of their attacks. As a result of the increasing level of combat in Indochina, the USIB gave responsibility for aerial reconnaissance of the areas where fighting was taking place to the SAC. Henceforth, SAC U-2s would be used over South Vietnam, parts of Cambodia Not linked to a story yet.
