Gavriil-class ships were originally intended to have an armament of two single
four-inch (102 mm) Pattern 1911 Obukhov guns and a dozen
torpedo tubes in six double mounts. The Naval General Staff changed this to four triple mounts once they became available and then decided to exchange a torpedo mount for two more four-inch guns in August 1915 while the ships were still under construction. One of these guns was mounted on the
forecastle and three on the
stern, aft of the torpedo tubes.
Anti-aircraft defense was provided by a
anti-aircraft (AA) gun in a single mount
amidships. The
Gavriils were completed with one triple torpedo mount between the forward
funnels and two mounts aft of the rear funnel. The ships could carry 80 M1912
naval mines. They were also fitted with a
Barr and Stroud rangefinder and two searchlights. ==Construction and career==
