The Grosjaschtschi class (Russian: Грозящий) was a class of three armored gunboats of the Imperial Russian Navy . The boats, built between 1889 and 1894, served in the Russo-Japanese War and the First World War .

history

The Otwaschny

The Grozyashchi- class boats were conceptually based on those of the Bobr- class . However, the design has been significantly further developed and changed. The ships of the Grozjashschi class were significantly larger and provided with reinforced armor. However, the setup and caliber of the main armament were retained , with new models being used each time.

The type ship of the class was laid down in 1889 at the Admiralty Shipyard in Saint Petersburg . It was launched on 19 May 1890 from the pile and was completed 1891st On the Admiralty Shipyard also emerged 1890-1893 Gremjaschtschi . The Baltic Shipyard took on the construction of the third unit, the Otwaschny , which began in 1890 and was completed in 1894 .

The Grozjashschi served in the Baltic Fleet , while her sister ships were used in the Far East . As part of the Pacific Fleet , both boats were lost during the Russo-Japanese War. While the Gremjashchi ran into a mine on August 18, 1904 and sank, the Otwaschny was sunk by its own crew on December 20, 1904 before Port Arthur was handed over to the Japanese . The Grozjashschi was still used in World War I, during which it received new armament. After the war it was demilitarized and broken up in 1922.

A further development of the Grojashchi class is the Chrabry , built between 1894 and 1897, which, with almost the same dimensions, received significantly different armament, a different armor arrangement and a higher foredeck.

technology

The steel hull was 72.26 m long and a maximum of 12.67 m wide. The maximum draft was designed for 3.71 m with a displacement of 1492 t. However, when fully equipped, the ships were much heavier. The Grozjashchi displaced 1627 tons, the Gremjashchi 1700 tons and the Otwaschny even 1854 tons. The drive consisted of two vertically arranged composite steam engines with triple steam expansion , each acting on a propeller . The necessary steam was generated by six coal-fired Belleville boilers , for which a fuel supply of 160 to a maximum of 200 tons of coal was carried. The machines made between 2050 and 2500  PSi , which enabled a top speed of between 13 and 14 knots.

The Grozjashschi with changed armament

The belt armor was 64 to 127 mm thick and reached from the stern to about 9.1 m in front of the bow , which was pronounced as a ram . At the front end of the belt armor there was a 89 mm thick armored cross bulkhead . The armored deck was made 25 to 37 mm thick.

The main armament of the ships was a 22.9 cm L / 35 caliber cannon installed on the forecastle. It had a lateral directional range of 100 °, which meant that the ship had to be aligned with the bow towards the enemy in order to fire. The second heavy artillery was a 15.2 cm L / 35 caliber cannon equipped with a shield on the quarterdeck. Moreover, the ships four to six 4.7-cm-L / 43-guns, four had 3.7-cm-L / 23-Hotchkiss - revolver cannon and two disposed above water torpedo tubes with 38 cm diameter on board. They were also able to carry 20 sea ​​mines .

During the First World War, the Grozjashschi received a new armament. It consisted of four 15.2 cm L / 45 guns, one of which was placed on the bow and the other three in the midship line on the quarterdeck, and two 11 pounder anti-aircraft guns .

The crew of the ships had a nominal strength between 178 and 188 men.
