Abstract : The Heliborne Illumination System was designed to supplement other methods of illumination in night combat operations. The HIS was flown under varying terrain, weather, and operational conditions on training and combat missions. Fifteen missions were observed by evaluators from the Army Concept Team in Vietnam (ACTIV). Additional data were gathered by interview and discussion with key personnel. Generally, 2500 feet absolute was the most desirable altitude for the tactical employment of the HIS. An observer helicopter is normally required for surveillance of relatively small areas, troop formations, weapons emplacements, fortifications and similar-size targets. The observer helicopter follows the HIS just outside the light beam and at an altitude of 300 to 500 feet. A fire team of 3 armed helicopters trails 500 feet to the rear and at an altitude of 1500 feet absolute to provide protection for the searchlight and observer helicopter and also firepower for target engagement. The HIS evaluated in this project is a satisfactory interim solution for the increased night illumination requirement.
