Development and description

The gun was designed in 1928–1930 and entered service the latter year. It weighed 3,660 kilograms (8,070 lb) and had an overall length of 5.76 metres (18 ft 11 in). Its 52-caliber barrel was 5.43 metres (17 ft 10 in) long. The gun fired 10.5-centimetre (4.1 in) fixed ammunition with a 14.7-kilogram (32 lb) projectile at a muzzle velocity of 925 metres per second (3,030 ft/s). This gave it a range of 17,250 metres (18,860 yd) at an elevation of 30°.

The gun was only used on the single-gun MPL C/30 mounting. It had a traverse of 360° and elevation limits of -10° and +30°. The manually operated mount could be traversed and elevated at a speed of 3° per second. The gun had a rate of fire of 15 rounds per minute.

The guns aboard the Type 24 torpedo boats Luchs and Leopard were bored out in 1932 to 12.8 centimetres (5 in) and served as prototypes for the 12.7-centimetre (5 in) SK C/34 gun.
