The following historic information was provided CW4 George Arzente and is from AVIAN 34 published in 1970. He is also in the process of starting a Website for the 539th Trans Company. Contact him directly if you can help with material for his project.


Until early in 1966, supply and maintenance for the Army's aircraft in the Republic of Vietnam came under the control of the US. Army Support Command. This organization was composed of two Transportation Battalions (Aircraft Maintenance and Supply) the 14th with one direct support company and the 765th with one general and two direct support companies. Supply support was handled by the Aviation Supply Point at Tan Son Nhut Air Base, which was carrying 8,000 line items in support of 660 aircraft.

Major General John Norton, then Commanding General of the US Army Support Command, Vietnam, realized that his organization would be unable to handle the large aircraft buildup projected for 1965 and 1966. To meet this problem, General Norton appointed an ADHOC committee arid gave it the project of creating an aviation logistical support organization capable of meeting the demands of the projected aircraft buildup.

The committee was given two guidelines. First, the new organization should be structured to provide one-stop maintenance (i.e., support at one location not only for the aircraft, but for its associated avionics and weapons systems as well). Secondly, the new organization should be able to grow with the expected buildup of aircraft.

Based on the recommendations of the committee, the 34th General Support Group (Aircraft Maintenance and Supply) was formed provisionally in November 1965. It was activated in January 1966 and given the responsibility of .... . providing command and control of assigned and attached units performing the aircraft, avionics and air armament maintenance functions in the Republic of Vietnam". This mission includes aircraft maintenance and supply support for all Free World Forces in Vietnam.

Upon activation, the Group was composed of the 14th and 765th Transportation Battalions, along with assets drawn from the Army Support Command. During the first year of its existence, two more battalions were brought to Vietnam and placed under the control of 34th Group. The 58th Transportation Battalion (Aircraft Maintenance and Supply) (General Support) and the Floating Aircraft Maintenance Facility (FAMF), 1st Transportation Battalion (Seaborne) raised the Group's strength to four battalions. In March 1967, another General Support Aircraft Maintenance and Supply Battalion-the 520th was added, and in February 1968, the US. Army Aviation Materiel Management Center (AMMC) was placed under the operational control of the Group.

With the addition of these organizations, the 34th Group has been able to render general support to all Army aircraft in Vietnam. It is providing back-up direct support to divisional units in-country, including the 101st Airborne, Americal, 4th Infantry, 25th Infantry, and the 1st Cavalry (Airmobile) as well as the 1st Aviation Brigade. Other USARV aviation units receive direct support from the 34th Group.

In addition to meeting the needs of US. Army aviation, 34th Group also provides logistical support to elements of the Royal Australian Air Force, Republic of Korea Air Force, Royal Thai Army, US. Navy, US. Air Force, and the US. Marines.

Commanded by Major John Webster, this unit is responsible for providing general support to more than 1,000 aircraft, as well as reassembling, test flying, and issuing all Army aircraft arriving in Vietnam through DaNang. Most of the aircraft handled by the 610th belong to the Americal and 101st Airborne Divisions.

Although the 610th is classified as a general support unit, it does perform back-up direct support maintenance when necessary and has the capability to perform limited depot-level maintenance (with the exception of mainframe repair). It also provides technical assistance teams to various aviation units in area for needed on-the-spot assistance,

The 263rd Light Equipment Maintenance Company (GS), commanded by Major Roy Doubrava, is responsible for maintaining the avionics systems of all Army aircraft in Military Region I. Although the unit averages more than 130 work orders a day, it has never had a customer aircraft lose a day out of action due to an avionics The 263rd lives up to its motto of "Finest Support"

Pipesmoke Professionalism

from George Arzente

Although the 34th Group, as a maintenance and supply organization, performs a vital but rather unglamorous mission, it does include one unit that is involved with a very exciting job day after day. The "Pipesmoke" recovery team of the 520th Transportation Battalion is responsible fox. most of the field and maintenance extractions of downed Army aircraft in Military Region 3, many of which are performed under the adverse conditions of enemy fire, darkness, and bad weather. -Traditionally, recovery of aircraft in Vietnam has been a coordinated effort between the direct support company, supplying a rigging helicopter with crew to prepare the downed aircraft for recovery, and the general support unit providing the CH-47 "Chinook" for the lift. The "Pipesmoke" recovery team is a unique(.' unit in that both the rigging and extracting elements are under unified operational control. This is made possible due to the close proximity of the 520th Battalion units and results in the most efficient, best equipped, and most highly trained recovery unit in Vietnam.

Recoveries are categorized in two ways. Routine Maintenance evacuations involve the aerial transfer of aircraft that are not operational due to mechanical failures, repairable combat damage or accidents. These aircraft require airlifting from one secured area to another for repairs. The second type of recovery is known as a Field Extraction and involves disabled aircraft that have been forced down beyond the safety of base camp perimeters. To keep these aircraft out of the hands of the enemy, immediate extraction is essential.

Averaging approximately 45 maintenance evacuations and 40 field extractions a month, the men of "Pipesmoke" have made more than 3,500 recoveries since April 1967.. This figure represents not only recoveries made - for maintenance and supply customers of the 520th - Battalion, but all other aviation units within Military Region 3 that require assistance During the recent Cambodian operation the Pipesmoke team followed aviation units across the border and recovered aircraft for both the United States Army and the Vietnamese Air Force.

Late last fall, "Pipesmoke" achieved a notable first when it recovered a fully equipped CH-47 "Chinook" by using a "C" model CH-47 and airlifted it from Phu Loi to Saigon. This recovery marked the first time a "Chinook" had been recovered in Vietnam without having been first stripped of all detachable components, and demonstrated that the valuable helicopter could be moved out of danger much faster than was ever thought possible.

Requests for recovery missions come to the "Pipesmoke" operations center in Phu Loi by telephone from the owning unit or by air-to=ground communication from an aircraft at the scene. The "Pipesmoke" crew members are briefed on the mission and prepare the necessary rigging gear and Once on the scene, the recovery is made swiftly and carefully. Each man has a specific job, and in coordination with other members of the team, performs with long-practiced skill.

The personnel of "Pipesmoke" are drawn from the 520th Battalions resources. The enlisted personnel are all volunteers and hold highly sought positions The men of "Pipesmoke" are considered to be the finest and most knowledgeable maintenance personnel in the 520th Battalion and hold a prestigious reputation throughout the 34th Group.

Here is a some history about the 605th Transportation Company (ADS) as I remember it. Also, I'm was not a transportation MOS soldier, I was 34D2 (EDP Repairman), which is a Signal Corp MOS.

605th TC (ADS) - The (ADS) was Aircraft Direct Support. When I was with the unit, we were station in Phu Loi (about 25 clicks north of Saigon). I believe the unit moved into the delta area in 70 or 71. The unit had three functions, salvage, repair and parts.

Salvage - This is where the Pipesmoke name was used, it was the unit's call sign. We had (I believe) four UH-1 "Hueys" and 4 CH-47 "Chinooks". The "Pipesmoke" platoon was responsible from recovering any aircraft wreckage from the field. The word "Pipesmoke" was painted on the roof of operations shack.

Repair - The unit has a repair and maintenance hanger. The was quite a few civilians from the LSI corp. that lived in our company area and worked in this area.

Parts - Unit had a parts warehouse and serviced all the near by units. This where I worked. We had a NCR 500 computer system that was mounted in two 40 foot van trailers next to the warehouse. All the aircraft parts that we had on were inventoried on this system and I was the repairman.

As with any Army unit, we were always short on people for different jobs, so one of my "other" jobs with the unit was truck driver. I OJTed on a 5 ton tractor and flat bed trailer for a couple of weeks, then was cut loose making the twice weekly trip to Saigon/Ton Son Hnut.. That was a lot fun (I hated working on the computer system).

Another interesting fact about my unit, about 25-35% of the unit from Oct 68 to Oct 69 was made up of Army Reservists from Greencastle, PA. I don't remember the unit's name, but they were activated, training for a year at Fort Lee (I think) and then were deployed to RVN as fill ins to the 520th TC Bn. Thats about all the history of the 605th that I remember, hope it helps. And again, thanks for the ATA page.


Aerial view of the 605th Transportation Company (ADS) at Phu Loi, take sometime between April and June 1969. The unit was located between the tow roads that intersect at the bottom of the picture and let out the west gate onto highway ??. The large building at the top right center was the maintenance hanger. The buildings in the row below the hanger was the billets that the civilians from LSI lived in. The next row is the company's HQ building (white roof), officer and senior NCO billets. Building below the HQ building is the mess hall. The next row down were troop billets, then the "Club" with it's outdoor movie screen in front, volley ball court and supply/arms room on the right. The next row of buildings were troop billets (mine was the middle one). The next row was an empty building and another troop billet. The last small building by the road on the right was one of the most important buildings around (especially late Monday mornings), the crapper. The circle at the bottom left was the shit pit, were Papa-san burnt the barrels from the crappers.

The large building was the parts warehouse, building on the right was the warehouse office and the trailer behind the barrel blast wall was the computer van (this was my primary work area). Photo was taken from the motor pool.

Inside the computer vans. This was a NCR 500 computer system, which was a magnetic card ledger system for tracking parts from the warehouse. There were also 3 IBM keypunch machines and a card sorter.

USNS Corpus Christy Bay, The Floating Aircraft Maintenance Facility

Photo from Bob Morris

"The most unique unit assigned to the 34th was the USNS Corpus Christy Bay, also known as the 1st Transportation Battalion (Depot)(Seaborne). In actuality, this was a floating aircraft maintenance facility which arrived on 12 April 1966 carrying 370 Army maintenance personnel and 130 civilian crewman. Thirty seven maintenance functions were consolidated aboard this ship, allowing it to function as a depot level repair facility capable of doing complete overhaul and of fabricating components. Additionally, it carried a library of 180,000 engineering drawings on film and could broadcast over closed circuit TV drawings to satellite maintenance facilities. The Corpus Christi Bay arrived in Cam Ranh Bay in April 1966. She moved out of Cam Ranh Bay on 21 Sep 1966 and sailed to the harbor at Qui Nhon to be near the 1st Cavalry, the unit she primarily supported. The majority of support performed by this vessel was in open rice paddies and jungle clearings.[The U.S. Army in Vietnam, Leroy Thompson, p 132-133] I also found a picture of it anchored at Vung Tau [r.g.]

Army Aircraft Maintenance and Support in Vietnam

Growth of Aviation Logistic Support in South Vietnam From an austere beginning when two helicopter companies arrived in Vietnam on 11 December 1961, the total number of U.S. Army aircraft increased to 510 by 1 January 1965 and then further increased to a peak of 4,228 by September 1969. When the buildup commenced in 1965, the U.S. Army Support Command Vietnam had one aircraft maintenance and supply battalion (765th Transportation Battalion) to provide backup direct and general support for all Army aircraft in-country. This battalion was located at Vung Tau and consisted of direct support companies and one general support company. The three direct support companies were located at Vung Tau, Saigon, and Nha Trang. They provided back-up support for separate aviation companies having their own organic or attached direct support and they provided direct support for small aviation detachments that lacked this capability.

The decision reached was to establish a separate headquarters under the direct command of U.S. Army Vietnam. This basic organizational structure has operated throughout the Vietnam Era with only one minor variation. Originally, the command was under the staff supervision of the U.S. Army Vietnam G-4. In October 1967, staff supervision was changed to the U.S. Army Vietnam Aviation Officer. Following the September 1965 decision to establish a separate command, the next two months were spent in developing an organizational structure and preparing the necessary authorization documents. In November 1965, a group headquarters was established on a provisional basis and finally, on 17 January 1966, a U.S. Army Pacific General Order was published activating the 34th General Support Group.
