On October 6, Russian Gepard-class missile frigates Dagestan and Tartarstan reportedly fired two 3M-14 Kalibr cruise missiles striking targets approximately 180 km away on Chechen Island in the Caspian Sea. Kalibr (NATO: SS-N-30A) is a medium-range land attack cruise missile usually armed with a high explosive (HE) warhead, though it may also carry a nuclear payload. The Caspian Flotilla, which includes the two missile frigates, also tested its missile defense capabilities using the Podsolnukh-E over-the-horizon radar and Buk-M3 medium-range antimissile system.
