The Junkers Ju 86 is a monoplane bomber and civilian airliner designed and produced by the German aircraft manufacturer Junkers. It was designed during the mid-1930s in response to a specification for a modern twin-engined aircraft suitable for use as both a high-speed airliner and a bomber. Junkers responded with a low-winged twin-engined all-metal monoplane; unusually, it was intended to be powered by Junkers Jumo 205 diesel engines instead of petrol engines for greater fuel efficiency. It also had a smooth metal skin instead of the company's traditional corrugated exterior. On bomber-configured aircraft, bombs were carried vertically in four fuselage cells behind the cockpit; these bomb cells were replaced by seating for up to ten passengers on the civil airliner version of the Ju 86. On 4 November 1934, the first prototype, powered by Siemens SAM 22 radial engines, made its maiden flight; on 4 April 1935, the third prototype, which was the first civil-configured aircraft, flew for the first time.

the variant of the junkers ju 86 z1, was the last variant of the bomber, where the structure of the ju 86 p was used, which was a variant of the aircraft with the ability to fly at very high altitude, and the high altitude bomber capability was installed, capable of carrying up to 2000 kg of bombs,
