NAM PHONG CONSTRUCTION

In 1966 Nam Phong was conceived as a supplemental US Air Force Base in the Khon Kaen district,Thailand.

[Note: Rumors that a dirt airfield existed in the vicinity of the new airfield location in Khon Kaen, Thailand, are apparently valid - a listing of Air Accidents (numbering over 1000 in Thailand from 1929 to 2014) compiled by Steve Darke of PWS Ltd records an RAF Sycamore HR-14 Helicopter "damaged when the rotors hit a wall during take-off from Nam Phong RTAFB" on 14 Dec 1960. Whether this was the same location the airfield was constructed , or the RTAFB was relocated upon airfield completion is unsure.]

Nam Phong was envisioned either as an "expeditionary base" (with steel AM-2 matting) or as a "permanant base" (concrete airfield). Or not at all - the DoD, State Department and Johnson Administration wasn't of one mind on much of anything at the time, much less consistently, and even less so with Nam Phong.

Amid the ambiguity, the Air Force apparently also considered a full-blown installation as evidenced by rather elaborate site plans. This would have been quite suitable for the contemplated Air Force EC-121 AWACS aircraft. But this obviously didn't survive the ongoing political and budgetary planning process.

Something in between expeditionary and permanent was decided (at least for initial construction) and Utah Mining Corporation was contracted by the the US Navy to simultaneously construct a "bare" Nam Phong airfield and expand RTAFB Korat, 120 miles south of Khon Kaen. However, with the "down-grade" of Nam Phong to a "bare" field, no further enhancements were authorized as the Air Force (and Utah Mining Corp.) hoped. The EC-121 AWACS (553rd Recon Wing) were instead deployed to RTAFB Korat following completion of the Korat expansion project, and envisioned siting of the new Air Force F-111 did not pan out. [Six F-111's were deployed to Thailand for combat trials in 1968, but soon three were lost (due to horizontal stabilizer problems) and the combat trials, and possible siting at Nam Phong, were abandoned.]. 
  
The Nam Phong airfield construction project segment was classified and performed under pretense of the expansion at RTAFB Korat, with both project segments completed in 1967.
However, despite Nam Phong construction being "classified", the Washington Post managed to let the cat out of the bag.
[see Washington Post 1966 article]  

From 1968 until 1972  Nam Phong, as a "bare" air field, would be used exclusively by covert USAF Special Operations Airmen ("Blue Berets"), US Army Special Forces ("Green Berets"), and Thai and Laotian counter-insurgents and their T-28 fixed-wing and UH-1M, (and CH-47, and CH-53 special forces) rotary wing aircraft as part of Project 404 / Project Unity, until Task Force Delta arrived in April of 1972.
