Germany was the first country that examined the opportunity of having guns especially designed to combat balloon, dirigibles and planes. In 1906 at the Berlin automobile exhibition Rheinmetall showed a 5cm L/30 pivot gun mounted on a lightly armoured motor car, while Krupp choose a 6.5cm L/35 gun. The tactic suggested was to deploy these vehicles in likely places and, on the appearance of an aircraft, to drive them rapidly to some point of interception, and open fire there.
that time the War Ministry believed that there were no need for special guns,
and in 1907 the German Army tested as anti-aircraft guns the guns then
adopted by field and foot artillery : 7.7cm field
gun, 10.5cm light field howitzer and 10cm heavy gun. In spite of the lack of
interest shown by the Army, studies went on. Between 1908 and
was only from 1910 to 1914 that the military leaders of the other major
European countries began to examine the prospect of anti-aircraft weapons. In
Great Britain Vickers produced a 3-pdr quick-firing gun mounted on a Daimler
car chassis, while in
In October 1914 there were 9 motorized and 27 horse-drawn Bak.
In January 1915, thanks to a great use of captured guns, there were 97 Bak, mostly armed with Belgian, French and Russian field guns transformed into anti-aircraft gun.
