1963 – 1968
As a signatory of South East Asia Treaty Organisation (SEATO), Britain had an obligation to assist Allies in the Far East.
In early 1960’s, the Americans (also a signatory to SEATO)were becoming increasingly embroiled in preventing the march of Communism in Laos and Vietnam, they requested that Britain assist in their crusade.
In February 1963, it was proposed that Britain construct an Airfield at Loeng Nok Tha, near Mukdahan in Thailand, as part of the American’s Special Logistic Aid to Thailand (SLAT).
The proposal was accepted and given the code name “Operation Crown”.

Work would be carried out in two dry seasons:-
Jan 64 – June 64 –Clearance, Cut and Fill.
Oct 64 – June 65 – Complete Cut & Fill, Drainage & Surfacing.
513 Specialist Team (Airfield Construction) based at Deverell Barracks Ripon, did the Recce for Op Crown and the very 1st part of that recce was done in England in the Swindon area in early 1963. This specialist team consisted of surveyors, draughtsmen and soil mechanics, based in the RM College of Science at Shrivenham.
HQ Op Crown formed in Gilman Barracks, Singapore, where time was spent drawing stores/vehicles and getting them ready for shipping up to Thailand.
Lt.Col "Mad" McIntyre MC and RSM 'Timber' Wood were in command of the HQ Op Crown.
Flying out of RAF Changi (Singapore) in an Argosy to Ubon and by road to Mukdahan.
The advance party lived in hotels in Mukdahan until the tented camp was built.
The Movements Liason Officer & NCO was Cpl. Stan Sissons.
Over the following couple of weeks, HQ staff were travelling up & down between Mukdahan and Kok Talat, surveying the roads.
Once the Tented Camp was finished, HQ Op Crown moved in.
The area decided for the Airstrip, was right in the middle of a ‘paddy field’, under 2 to 3 feet of water, more during the monsoon period. It had no less than 7 individual rivers running across the site.
The water area seen under the aircraft engine, is the site for the Airstrip.
