surrender as condition for the town to avoid shelling by the Ottoman Navy. World War I They did not take an active part in the Second Balkan War, however they did see active service in World War I, during which Shumni was sunk by mine on 11/12-9-1916. After World War I the remaining five were judged to be obsolescent and were subsequently reclassified as patrol boats. In 1934 the 3-pounder guns were removed and replaced with two SK C/30 AA guns. World War II When Bulgaria entered World War II on the Axis side, Drazki and her four remaining sisters were antiquated but still capable of carrying out patrols. In 1942 the two SK C/30 AA guns were removed and the 3-pounders were reinstalled. On 15 October 1942, Drazki sank in Varna harbour after a magazine explosion, but she was soon repaired. In 1944 however, she became a gunnery target ship and remained in service in that capacity until the 1950s. Museum ship In 1957 it was decided to commemorate the 50-year-old Drazki, as she was by far the most famous ship in the Bulgarian Navy. However, by that time she had been at least partially broken up for scrap. Her gun, funnel and some of the deck and hull fittings were installed on board her sister ship Strogi, which, after 21 November 1957, became the museum ship Drazki. She is currently preserved as a static land display at the Naval Museum in Varna. Her other sister Hrabri was scrapped in 1962. In 2006 a Wielingen class frigate Wandelaar bought in Belgium for the Bulgarian Navy was named Drazki, and given the identification code F41.
