On February 1967, the 57th Aviation Company was reeorganized from an Airmobile Fixed Wing Company (OU-2) to an Assault Helicopter Company by General Order 52, Headquarters, Third U.S. Army. In October 1967, the unit was deployed to Vietnam and by December 1967 it was operating out of it's new home at Kontum Airfield.

  During the past year the 57th Assault Helicopter Company provided tactical air mobility of combat troops, supplies, equipment and attack helicopter fire support for the 4th Infantry Division, 5th Special Forces Group, 1st Field Force, MACV and various units. The area of operations was the II Corps Tactical Zone.

   July 1969 saw the 57th distinguish itself at the seige of Ben Het and Dak To by getting urgent resupply into the compounds and evacuating the wounded under intensive enemy ground fire. The 57th did this with a minimum loss of aircraft and personnel by using tactical maneuvers and experience gained from working for the 5th Special Forces. Once the enemy had been force to break the seige and retreat back across the border the 57th resumed its normal missions. The monsoons had moved in and flying conditions had deteriorated to the point where missions where cut in half. November, saw rumor control strike again with word being put out that the 57th was to prepare for a move. This was taken with mixed emotions as many of the people had seen Kontum Airfield develop from an abandoned airstrip into a small city. Forntunately for many, the move never materialized until March 1970. It was then that the 57th moved to An Khe to support the 4th Infantry Division. It wasn't long before the 57th was flying once again in the Kontum area as a strong NVA force was attempting to overrun Dak Seang.

  On the 3rd of April the 57th led the first flight of slicks to insert troops to break the seige. Intensive ground and mortar fire made the insertion extremely hazardous but the mission was completed with the loss of only one aircraft and it was from another unit. The entire month saw the 57th at Dak Seang inserting troops and resupplying the battered compound. For the 57th, twelve aircraft suffered combat damage and one was destroyed. Six crew members were wounded but none were hurt seriously and there was no loss of life. After Dak Seang there would be no rest for the 57th because Cambodia was to be the next objective. On the initial insertion of the 4th Division into Cambodia on 6 May heavy enemy contact was made causing four of our aircraft to be damaged and one destroyed but once again the 57th's luck held out and no one was injured. After the initial insertion contact with the enemy became light and the normal business of resupplying, inserting troops and bringing back captured equipment was carried on without any mishaps. By early June all the U.S. forces that the 57th was supporting had been withdrawn from Cambodia and An Khe became primary area of operation.

  The men of the 57th take pride in themselves by knowing that they met and completed all missiions given to them in a professional manner that exemplifies the highest traditions and standards found in Army Aviation.
