When the First World War ended,
Junkers were developed for civilian use.
The construction of the J.1 and the J.4 during the war was for
patrols along the front lines where there was heavy ground fire.
The all-metal construction, with additional armour around the
crew, engine and gas tanks, made the Junkers very resistant to
heavy ground fire.
Among the many different models of Junkers developed over the
years were the
Junkers-Larsen 6, the F.13, W.33, and W.34.
In 1919, the Junkers F.13 was used by civilian aviation
companies, and was considered the finest of aircraft, with its
closed cabin, durability and versatility.
Modifications to the F.13 were made in 1926 to create the new
W.33 and W.34, which provided a larger fuselage. The W.33 was
developed as a freighter and the W.34 was built as a passenger
and freight aircraft.
Bush pilots used these Junkers with companies like Canadian
Airways, Canadian Pacific Airlines, Central B.C. Airways, and
Pacific Western Airways. Pacific Wings had at least one Junker
in the early 1960s.
Various models of the Junker were used as floatplanes.
