History

The Austro-Hungarian Empire began to lay down plans for a much expanded naval force in the early 1900s. No longer content with a coastal defense force, they wanted to have control over the Adriatic Sea. The change was influenced by the politics of Marinekommandant (Chief of the Navy) Rudolf Montecuccoil and crown prince Archduke Franz Ferdinand who viewed Italy as a threat, along with the new railway linking their ports at Trieste (present-day Italy) and the Dalmatian coastline (present-day Croatia) to the rest of the Empire. The new fleet expansion program led to orders for a new cannon to arm their destroyers and scout cruisers leading to the Škoda K 10 first developed in 1907 and adopted in 1910. After World War I ended, the Austro-Hungarian Empire was dismantled by the Allied Powers. This dismantling included the navy with Italy getting the K 10 guns on the Brindisi and Venezia which were ships ceded from the Austro-Hungarian Navy as war reparations.

The Italians were so enamoured with the design, they began to produce the design locally through OTO which resulted in a variety of different variants of the design. The O.T.O. Mod.1928 was a dual-mount anti-aircraft variant with electrically powered adjustable trunnions, rope rammers and mechanized spring, and a loose liner. Despite being intended for anti-aircraft use, the gun was too slow for this role, particularly if a ship was rolling and it was instead more suited for barrage fire. The RN Balzano, Condottieri-class, RN San Giorgio, and Zara-class cruisers all used these guns. They were also used on the Conte di Cavour-class dreadnoughts. The Soviet Navy also used this gun as the Minizini named for the developer of the duel mount Italian Commandante Minizini.
