15 cm Kanone 18 Wikipedia
In 1933 Rheinmetall began development of a new artillery piece to fulfil a German Army requirement for a replacement of the aged 15 cm Kanone 16, with the first production units received in 1938. There was not much of an improvement over the older gun as it weighed two tons more than the K 16, but only had 2,290 metres (2,500 yd) more range. The army was happy with the range, but not with the carriage. There was a special transport carriage for just the gun when traveling long distances. Putting it on its turntable took even more time to assemble.
Around a hundred were built between 1939 and 1943. It was not popular in service as it was regarded as too much gun for too little shell. This caused its production to be terminated in August 1943. Many were used in coastal installations.
