The Isjaslav class was a destroyer class of the Baltic fleet of the Imperial Russian Navy , which was based on the design of the prototype boat Nowik , ordered in 1912 and built there in the wake of the small shipbuilding program approved for the Baltic Sea in June 1912 .
Due to the First World War , the shipyard in Reval was only able to complete two boats. At least two hulls were still towed to Petrograd , but only one was completed by 1925.
The Awtroil , which was completed as the second class destroyer in 1917, surrendered to British units in the 1918 Civil War , which they handed over to Estonia . The Estonian Navy in 1933 sold the in Lennuk renamed boat along with the obtained also through the British destroyer Vambola (ex Spartak , Kapitan Miklutscho-Maklaj , Kapitan King Bergen ) the Leitenant-Iljin class in Peru , where it was kept in service until 1948 .
draft
Compared to the Nowik draft, the concept had been enlarged a little. The plans were drawn up for Lange & Böcker with the help of the French shipyard Chantiers et Ateliers Augustin Normand in Le Havre , which also provided technical assistance. The originally approved plan initially only provided two 102 mm guns and twelve 457 mm torpedo tubes. After a reassessment, however, it was decided to increase the artillery component to a total of five 102 mm guns with a simultaneous reduction in torpedo equipment. The turbines were ordered from the Swiss company Brown-Boveri. However, due to the outbreak of war and the Swiss embargo policy, they were only delivered for Awtroil and Isjaslaw , so that new orders were placed with British companies for the remaining boats.
Similar boats were the nine boats of the Derzky or Bespokoiny class of the Black Sea Fleet and the eight boats of the Orfei class , which were completed in 1915/1916 at the Ust-Ischora shipyard of the Petrograd metal factory; the five boats of the Leitenant-Ilyin class , of which the Putilow shipyard in St. Petersburg completed three in 1916/1917 and two only completed in 1927/28 for the Soviet Navy and the three boats of the Gavriil class , the 1916/17 of the Russian-Baltic plants in Reval were completed. The foreign sponsored shipyard for the aforementioned Baltic Sea boats was Blohm & Voss .
Boats and Fates
Five boats of the Isjaslav class were started at the Lange & Böcker shipyard in Reval from late autumn 1913. The first boat was launched on November 22, 1914 as Gromonosez , followed in 1915 by Awtroil , Prjamislaw , Brjaschislaw and the first boat in equipment was renamed Isjaslav . The expansion of the boats was slow. The Isjaslav was finally completed on June 29, 1917, followed by the Awtroil on August 12. It is unclear whether the fifth boat was launched in 1917. At least two hulls were still towed to Petrograd in February 1918, but only one was completed by 1925.
The Awtroil , completed as the second destroyer of the class, was used by the Red Fleet in the civil war for reconnaissance against the Estonian coast and surrendered to the destroyer Wakeful and the cruisers Calypso and Caradoc , who had provided them , on December 25, 1918 off Reval . The British handed the destroyer over to Estonia. In 1933 the Estonian Navy sold the Lennuk- renamed boat together with the destroyer Vambola (ex Spartak , Kapitan Miklutscho-Maklaj , Kapitan Kingsbergen ) of the Leitenant-Iljin class to Peru , where it was kept in service until 1948 .

The Red Fleet commissioned the Isjaslaw on December 31, 1922 as Karl Marx . In 1923 the expansion of the Prjamislaw was continued, which came into service on February 5, 1925 as Kalinin .
Both Soviet boats were lost in 1941.
The Karl Marx ran aground on August 7, 1941 in the Loksabucht in the Gulf of Finland and was blown up by the crew.
The Kalinin , which was modernized from 1937 to 1941, sank on August 28, 1941 on the Juminda mine barrier in the Gulf of Finland after a mine hit, as did the Jakow Sverdlov (ex Novik ) during the evacuation voyage from the Tallinn fleet base to Kronstadt .
