In 1960, the U.S. Army published a proposal for a new light observation helicopter to replace its Bell H-13 helicopter fleet, which was the Army’s primary helicopter during the Korean War. The Hughes helicopter company responded with its Model 369 to compete against entries from Bell and Fairchild-Hiller. The Hughes entry made its first flight in 1963. The design featured an egg-shaped fuselage that had excellent visibility for the crew, and the four-bladed articulated rotor gave it great agility.
