The 10 cm Kanone 14 (10 cm K 14) was a field gun used by Germany and Bulgaria in World War I. It was intended to replace the 10 cm K 04. In many ways, it was a heavily modified K 04 intended to be able to engage aircraft. It was mounted on a firing platform to give it a fast 360° traverse. Its elevation was increased 15° over the older gun and it was given a heavy and complicated variable recoil system to minimize problems when firing at high angles. A double elevation sighting system was fitted to increase accuracy against aerial targets. Despite these modifications, it proved to be a complete failure as an anti-aircraft gun. It was placed into production on the outbreak of World War I and the first guns were delivered by May 1915.
