Light Observation Helicopter

An OH-58 Kiowa, winner of the LOH competition's second round

The Light Observation Helicopter (LOH) program was a United States Army program to evaluate, develop and field a light scout helicopter to replace the Army's aging OH-13 Sioux. The program gained impetus with the advent of the Vietnam War and was aided by advances in helicopter technology, specifically the development of the turboshaft engine. Three of the aircraft evaluated for the program would eventually enter military service, one as a training helicopter and two as observation helicopters used for battlefield reconnaissance missions.
