History of the full-size aircraft

The Junkers J.I, also designated J.10, was a German First World War armoured infantry-support and reconnaissance aircraft developed by Junkers. It was an unusual and technically advanced machine for its period, being constructed largely around a heavily armoured metal fuselage.

The aircraft was designed to operate at low altitude over the battlefield, where it would be exposed to rifle and machine-gun fire from the ground. Junkers therefore incorporated substantial armour protection around the crew and critical components. The aircraft's distinctive armoured fuselage was built from corrugated duralumin, a characteristic of several important Junkers designs.

The J.I used a conventional tractor arrangement with its engines mounted between the wings. Its large biplane wings provided the lift necessary for the relatively heavy armoured airframe, while the protected crew compartment gave the aircraft an unusual appearance compared with the lighter fabric-covered reconnaissance aircraft of the period.

Two Benz Bz IV water-cooled inline engines powered the aircraft. The substantial power requirement reflected the J.I's considerable weight, which was the inevitable consequence of its armour and heavy construction.

The J.I entered German service during the final year of the First World War and was employed primarily for low-level reconnaissance and infantry-support missions. Its armour gave the crew considerably greater protection against ground fire than many conventional reconnaissance aircraft.

The aircraft's large size and weight made it relatively slow and cumbersome, but those characteristics were accepted because the J.I was designed for a very different purpose from a conventional fighter. Its mission was to operate close to the battlefield and survive the hostile environment there.
The Junkers armoured aircraft concept

The J.I was particularly significant because it demonstrated Junkers' growing interest in all-metal aircraft construction.

At a time when most military aircraft were constructed from wood, fabric and wire, Junkers was developing techniques involving stressed metal skins and duralumin structures. The J.I's corrugated metal armour and structural components represented an important step in the evolution of metal aircraft.

The design philosophy would become increasingly influential after the First World War. Junkers subsequently developed aircraft in which stressed-skin metal construction became a defining feature, eventually contributing to the development of modern all-metal monoplane aircraft.
