Her five sisters were named: Smeli (Смели, "Brave"), Hrabri (Храбри, "Valiant"), Shumni (Шумни, "Noisy"), Letyashti (Летящи, "Flying") and Strogi (Строги, "Stern").

They were powered by a one-shaft triple-expansion reciprocating engine generating 1,900 hp which gave them a top speed of 26 knots.

[3] The Bulgarian Navy's torpedo boats took part in the First Balkan War between 1912 and 1913, serving in the waters of the Black Sea.

On 20 November 1912 Letyashti, Smeli, Strogi and Drazki were sent from Varna to intercept a group of Turkish transports.

Shortly after midnight on 21 November they encountered the Ottoman protected cruiser Hamidiye accompanied by two destroyers approximately 32 miles from Varna.

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 2006 a Wielingen class frigate Wandelaar bought in Belgium for the Bulgarian Navy was named Drazki, and given the identification code F41.
