Operational history

Einsatzgeschichte

 

1964  the RTAF acquired the first eight Fairchild C-123B Provider. The C-123B was acquired as replacement for the outdated C-47 Dakota. Until 1973 the RTAF procured 22 C-123B. Two of the planes were former HC-123B of the USCG with a AN/APN-158 radar in the nose. 1991 the last remaining C-123B.where withdrawn from service. 

 

1964 erwarb die RTAF die ersten acht Fairchild C-123B Provider. Die C-123B wurden als Ersatz für die veralteten C-47 Dakota erworben. Bis 1973 erwarb die RTAF 22 C-123B. Zwei der Maschinen waren ehemalige HC-123B der USCG mit einem AN/APN-158 Radar im Bug. 1991 wurden die letzten verbliebenen C-123B ausgemustert.

 

As addition and replacement for the C-123B starting from 1973 various C-123K were supplied to the RTAF. Many machines belonged in former times to the VNAF and the Air America. 20 planes could be identified yet, officially 24 planes wehre indicated. 1991 the last machines where deactivated. But three (576, 289 & 698) however had, of instruction of the king, re-entered service for the Royal Rainmaking unit in 1994. In 1995 the Type was finally withdrawn.

 

Als Ergänzung und Ersatz für die C-123B wurden ab 1973 diverse C-123K an die RTAF geliefert. Viele Maschinen gehörten früher der VNAF und der Air America. 20 Maschinen konnten identifiziert werden doch wird der Bestand offiziell mit 24 Maschinen angegeben. 1991 wurden die letzten Maschinen ausser Dienst gestellt. drei  (576, 289 & 698) mussten jedoch auf Weisung des Königs für die Royal Rainmaking Unit 1994 wieder in Dienst genommen werden ehe sie 1995 endgültig ausgemustert wurden. 

  In 1980, the Royal Thai government, seeking to extend the life of their C-123 fleet, placed a contract with the Monarco Aircraft Company, supported by the USAF, to convert a single C-123B to turboprop powerplants. Allison T56-A-7 turboprops were used, but by the time the aircraft, dubbed C-123T, was complete it had new wet wings, an Auxiliery Power Unit (APU) to assist with power steering of the control surfaces, and heating system for the cargo compartments that also fed a new deicing system. Budgetary restrictions forced the Thai government to abandon the program in 1981, and with a lack of interested parties development of the C-123T stopped.   Im Jahre 1980 suchte die königlich Thailändische Regierung, nach Möglichkeiten die Lebensdauer ihrer C-123 Flotte zu verlängern. Mit Unterstützung der USAF, wurde mit der Firma Monarco Aircraft Company ein Vertrag für die Umrüstung einer C-123B auf Allison T56-A-7 Turboprop-Triebwerke abgeschlossen. Die Maschine wurde als C-123T bezeichnet und war mit einem "nassen Flügel" (Treibstofftank im Flügel) und einer Stromver-sorgungseinheit (APU) ausgerüstet die die Steuerung unterstütze und die Heizung für den Laderaum gewährleistete. Budgetprobleme zwangen die Thailändische Regierung 1981 das Programm einzustellen auch da keine weitere Partei Interesse an der C-123T zeigte. 
 

The C-123B is designated Transportplane no. 4 (BL.4 .).

 

Die C-123B wurde als Transportflugzeug No. 4 (BL.4 .)  bezeichnet, während die C-123K als Transportflugzeug No. 4A (BL.4A บล.๔ก) bezeichnet wurde. Die C-123T hatte keine Bezeichnung im Thai-System.

USAF C-123K

In 1967 Thai crew member where brought into the USAF transport fleet to ease an existing pilot shortage. The Thai pilots where assigned to the 19 TAS (then 19 ACS Air Commando Squadron) of the 315 TAW at Prang Rang South Vietnam. The Pilots where send from the C-123B Sqn. of the 6th Wing at RTAFB Don Muang to Vietnam. The Thai pilots where highly qualified, even including a few instructor pilots in their numbers. In flying the 19 TAS Provider, they had only to get used the added jet engines of the USAF C-123K. The rest was of what they learned had to do with mission technique. The Thais stayed for a 6 month them in Vietnam before they rotated back to Thailand and where replaces by other crews. 

...

Although the Thai crews where often assigned to the regular aircraft of the 19 TAS, three of the 19 TAS C-123K carried Thai markings over the USAF paint, but the aircraft belonged still to the USAF. (54-650 c/n 20099, 54-686 c/n 20135 and 56-4360 c/n 20244)

...

The reason to use Thai markings was to give a visual evidence of the RTAF’s presence and the prestige of the crews to fly a foreign aircraft, even when they fly home to Bangkok and where greeted by the RTAF chief of staff. The C-123K where USAF planes and at each flight at least a member of the USAF had to be on aboard, given the Thai an impression being not “big enough boys”. The deployment of the RTAF in Vietnam ended at the end of 1970. 

 

 

USAF C-123K

1967 wurden Thailändische Besatzungen in die Transportflotte der USAF integriert da die USAF über zu wenige Piloten verfügte. The Thais wurden der 19 TAS (damals 19 ACS Air Commando Squadron) der 315 TAW in Prang Rang Süd Vietnam zugeteilt. Die Piloten wurden von den C-123B Staffeln der 6 Wing aus RTAFB Don Muang an Vietnam entsandt. The Thailändischen Piloten waren hoch qualifiziert sogar eine Instruktoren waren unter ihnen. Um die Provider der 19 TAS fliegen zu können mussten sie nur die Verwendung der Strahltriebwerke der USAF C-123K erlernen. Den Rest den sie erlernten hatten mit den zu fliegenden Missionen zu tun. Die Thais blieben für 6 Monate in Vietnam bevor sie nach Thailand zurückkehrten und durch andere Crews ersetzt wurden. 
Die Thai Crews wurden oftmals regulären Maschinen der 19 TAS zugeteilt, drei C-123K der 19 TAS trugen daher Thailändische Markierungen über denen der USAF, die Maschinen gehörten jedoch immer noch der USAF. (54-650 c/n 20099, 54-686 c/n 20135 und 56-4360 c/n 20244)
Der Grund für die Verwendung von Thailändischen Kennzeichen lag darin ein Zeichen für die Präsenz der RTAF zu geben und um das Prestige der Crews zu fördern die in fremden Maschinen flogen. Dies speziell wenn die Besatzungen nach Bangkok flogen und vom Stab der Luftwaffe empfangen wurden. Da die C-123K von der USAF waren musste auf jedem Flug ein Angehöriger der USAF an Bord sein, dies gab den Thai das Gefühl "junior Partner" zu sein. Der Einsatz der RTAF in Vietnam endete gegen Ende 1970.
