Bell OH-58 Kiowa Military Helicopter

Operational history
Major General John Norton, commanding general of the Army Aviation Materiel Command (AMCOM), received the first OH-58A Kiowa at a ceremony at Bell Helicopter's Fort Worth plant in May 1969. Two months later, on 17 August 1969, the first production OH-58A Kiowa helicopters were arriving in Vietnam, accompanied by a New Equipment Training Team (NETT) from the Army and Bell Helicopters. Although the Kiowa production contract replaced the LOH contract with Hughes, the OH-58A did not automatically replace the OH-6A in operation. Subsequently, the Kiowa and the Cayuse would continue operating in the same theater until the end of the war.
• Vietnam
On 27 March 1970, an OH-58A Kiowa (s/n 68-16785) was shot down over Vietnam, one of the first OH-58A losses of the war. The pilot, Warrant Officer Ralph Quick, Jr., was flying Lieutenant Colonel Joseph Benoski, Jr. as an artillery spotter. After completing a battle damage assessment for a previous fire mission, the aircraft was damaged by .51 cal (13 mm) machine gun fire and crashed, killing both crew members. Approximately 45 OH-58A helicopters were destroyed in Vietnam due to combat and accidents. One of the last combat losses was of an OH-58A (s/n 68-16888) from A Troop, 3-17th Cavalry, flown by First Lieutenant Thomas Knuckey. On 27 May 1971, Lieutenant Knuckey was also flying a battle damage assessment mission when his aircraft came under machine gun fire and exploded. Knuckey and his observer, Sergeant Philip Taylor, both died in the explosion.
