In the year 1959 was the first delivery of two Tupolev Tu-16, the license production agreement was signed in the late 1950´s by Xi'an Aircraft Industrial Corporation (XAC), and single parts were delivered to China and were assembled in Harbin. The aircraft resulting were first flown in September 1959. After the relations between China and the Soviet Union got broken, license production at Xi´an Aircraft Company slowed down, so that the first flight of the H-6A was on 24th December 1968. One year later production of the first (in comparison to the Tu-16 modified) version began; at least 120 aircraft were built.
