C-123K Provider

Serial Number: 54-658

After serving in Vietnam, the museum’s Provider went on to further distinguished service. After retirement from the US Air Force, it was acquired by the Department of State and was instrumental in the war on drugs in Peru. Moving food and medical supplies, building material, fuel and whatever else was needed to support the forward bases, the plane took hostile fire on several occasions and was instrumental, also, in transporting casualties to help and safety. Because of its unique capabilities as a cargo transport plane and its ability to use unimproved landing strips in remote regions, the Peruvians nicknamed this plane “El Burro.”


The Provider is a short-range assault transport used to airlift troops and cargo onto short runways and unprepared airstrips. Designed by the Chase Aircraft Co., the C-123 evolved from earlier designs for large assault gliders. The first prototype XC-123 made its initial flight on October 14, 1949, powered by two piston engines. A second prototype was built as the XG-20 glider. It was later test-flown, powered by four jet engines. The production version, with two piston engines, was designated the C-123B. Chase began manufacture in 1953, but the production contract was transferred to Fairchild. The first of more than 300 Fairchild-built C-123Bs entered service in July 1955. Between 1966 and 1969, 184 C-123Bs were converted to C-123Ks by adding two J85 jet engines for improved performance.

    Another proud flight engineer of the C-123k flying for the 356th out of Rickenbacker 1976 thru 1982 under Jack Romero. Charley Mercer and Frank Chraznowski trained me, I have many good memories with friends traveling all over in these birds.

  • I flew on the C=123K in Nakom Phanom Thailand with the “Candlesticks”. We flew night missions over The Trail. We were forward air control and flare drops. We carried a crew of pilot, copilot engineer and two loadmasters. We carried two starlight scopes and 100 flares, and spotted trucks and called in fighter support.

  • Can someone tell me what the internal cargo area dimensions were for the C-123 Provider?

  • I was a Loadmaster in the 24th SOW – 605th SOS at Howard AFB, Panama from June 1970 to August 1971. Checking my logs, I flew on this aircraft many times during that period.

  • I proudly served on board the C-123K as a ‘Flight Engineer’ in Vietnam under Operation ‘Ranch Hand’, having trained at Hurlburt Field, Eglin AFB, Fl., we were all ‘performance qualified’, Flight qualified, Airdrop qualified.. from there I was assigned to the 315th Air Commando Wing initially at Phan Rang AB, Vietnam. There were 2 parts to the Squadron, one being the famous or infamous some think ‘Spray Birds’, the second was the ‘Fly to were ever-when ever’ bunch, anything involving Troop movements, Cargo, Air Drop etc., I flew with the latter.. We were a bunch of ‘gung ho’ sort of group of young Air Crews, but were like ‘Brothers’.. I belonged to a small group calling ourselves the ‘Red Eyes’, each had a special designation call name, i.e. Tony-i, Dave-i, etc., We flew all over Vietnam. The most demanding mission was that of Volunteering to fly into the border between Laos and Vietnam to evacuate a Montagnard Village ( the famous peoples who so valiantly helped fight the VC and who where attached to Special Green Beret Units), We flew under the control of a FAC (foward air controller) dropped in specially for the mission.. there was nothing there except for a dirt kinda strip , our landing zone.. landed from up high, due to heavy mortar fire.. made a hard landing and evacuated the entire Village, did 3 trips in and back that day.. in the process getting peppered with small ground fire the entire time. My time with the C-123K Providers has been the Best of my time til now… just a bit of History for all to read and remember.

    • Howdy,
      The Ranch Hand Association will be holding its 51st reunion during Columbus Day weekend at the Ramada Beach Resort in Ft Walton Beach, FL. Feel free to be there.

    • Mr. Arzate, thank you for your service. I’m writing a story about a 123 crew and I wondered if I could ask you a few questions. First, in the literature, the crew is listed as four: pilot, co-pilot, navigator and flight engineer. Was there a loadmaster added in Vietnam? If not, who handled the cargo? If it was the flight engineer, did the pilot work his own throttles in the 123? My father was a flight engineer on a 118, and a 123 in the war, and I believe he told me controlled the throttles. Also, was the navigator usually an enlisted man? Thanks, I’d really appreciate any help you can give, and I thank you in advance for your time.

  • In the April 1956 entry I believe the base should be Sewart AFB, Smyrna, TN instead of Stewart AFB (New York). Very common mistake. In the Nov 1971 entry the word Lockbourne is spelled incorrectly. Really enjoying this web site. God bless our troops, past and present.

    While at Rickenbacker AFB I became the crew chief of this aircraft. I crewed it from 1974 till 1982. When the aircraft arrived at Rickenbacker the right wheel door was opened for the first time and a spent 50 caliber spent shell fell out. The aircraft was one of the most dependable of the fleet. It never aborted a flight while I crewed it. The left engine (#1) lasted to its time limit. It had been nearly maintenance free and it was decided to extend the overhaul time 10%. at the end we were slowly sending planes to Davis-Monthan AFB for final storage. One schedule to be shipped soon had low time engines. 658’s left engine was high time and was swapped to that airplane that left a few weeks later for storage. I was also a flight mechanic and flew a few maintenance test flights on it.

  • Allan Allridge

    I was a “Flight Line Mechanic” and flew on this particular aircraft as a “Flight Mechanic” for the Air Force Reserves at Rickenbacker AFB from 1975 to Nov 1976. I was with the 302nd TAW at that time that included all C-123Ks from Rickenbacker Air Force Reserve Base, 911 Pittsburgh USAF Reserve Base, Pittsburgh PA and Westover AFB MA. I flew all the Rickenbacker C-123Ks including UC-123-Ks, and all 911 TAS in Pittsburgh PA and accumulated over 1800 flight hours total as a Flight Mechanic. The official crew designation at time for the C-123K was Flight Mechanic and not Flight Engineer. The reason why from what I was told that Flight Engineers attended the USAF Performance Course and Fight Mechanic were not required to be performance qualified. I later attended the USAF Flight Engineer Performance Course at Altus AFB in 1982 when I was upgrading to a C-141B Flight Engineer position for the 313 TAS in Mc Chord AFB.

    While serving with the 82nd Abn Recon Company I was involved with some testing of the c-123s. We would load up at Pope AFB, short flight, land on a drop zone, same areas we jumped on (can’t remember which one now) not quite stopping the plane. tail was dropping as we were landing, got the green light while moving and we would exit the plane. Drive around simulating and assault and return to a landing plane, still moving forward on the drop zone, up the ramp, secure the “jeep” signal the flight crew and up we would go. Very exciting stuff for a young man. They were something new to all of us and they were just starting to use them as jump planes, I was jumping c-119’s Globmasters? c-118s I think and we were starting to use twin rotor helicopters, Shawnee’s I think also Beaver small aircraft. Lot’s of fun for a young guy. but I said that, smiling of course. this was around 1955 or 1956
