The Austro-Hungarian 305 mm Skoda 30.5 cm / 45 K10 naval gun was developed at the beginning of the 20th century and entered production in 1908. It is assumed that a total of no more than 65 cannons of this type were built. Its total weight was about 54.25 tons, a its barrel was about 13 meters long. The cannon was able to fire a projectile weighing 450 kilograms and send it an initial speed of 800 m / s. The maximum range was about 22,000 meters. The Skoda 30.5 cm / 45 K10 gun was obviously developed by the Skoda plant in Plzeņ as the main armament of the Radetzky and Tegethoff class battleships (also known as the Viribus Unitis type). It is worth adding that the earlier version of this gun, mounted on Radetzky units, had a smaller chamber and marginally worse ballistic parameters than the guns mounted on the Tegethoff dreadnoughts. In general, it can be assumed that the Skoda 30.5 cm / 45 K10 gun had parameters and combat capabilities similar to other naval guns of this caliber in Europe at that time, and it was certainly comparable to the Italian gun 305 mm / 46 Model 1909 mounted on battleships Leonardo da Vinci or Dante Allighieri. It is worth adding that after World War I, Italy used captured guns Skoda 30.5 cm / 45 K10 as coastal artillery.
The Austro-Hungarian 15 cm K10 sea gun, caliber 149.1 mm, was developed at the beginning of the 20th century and entered production in 1912. It is assumed that a total of no more than 50 cannons of this type were built. Whole the length of the cannon was about 7.5 meters. She was able to fire a projectile weighing 45.5 kilograms and broadcast it an initial speed of 880 m / s. The maximum range was about 15,000 meters. The Skoda 15 cm K10 cannon was obviously developed by the Skoda plant in the city of Plzeņ. It was designed as an additional armament for battleships (dreadnoughts) of the Tegethoff type (also known as the Viribus Unitis type). Each of the battleships of this class had 12 Skoda 15 cm K10 guns mounted in armored casemates - six on each side. It is worth adding that after 1918, the battleship SMS Tegethoff was handed over to Italy as war reparations, and then the presented guns were dismantled and used as coastal artillery in Libya and in today's Croatia, where they survived until the outbreak of World War II.
The Austro-Hungarian 66mm Skoda 7 cm K10 naval gun was developed between 1910 and 1912 and entered service in 1912. Whole the length of the cannon's barrel was about 3.5 meters. Gun was able to fire a projectile weighing 4.5 kilograms and broadcast it initial speed of about 880 m / s. The maximum range when shooting at sea targets was approx. 8,000 meters, and when shooting at air targets, it did not exceed 5,000 meters. The Skoda 7 cm K10 cannon was of course developed by the Skoda plant in the city of Plzeņ. It was designed as a fast-firing sea cannon, intended to counter small but fast-moving ships the size of a torpedo boat. These assumptions were met to a large extent, as the theoretical rate of fire of this gun was up to 12-15 rounds per minute. Cannons of this type were mounted, among others, on: Tegethoff type dreadnoughts (also referred to as the Viribus Unitis type), Radetzky type battleships, or Monarch type coastal defense battleships. The cannon was also used as an anti-aircraft weapon, and after 1918 in Italy as coastal artillery.
