Kalibr
The 3M-54 Kalibr, (Калибр, caliber), also referred to it as 3M54-1 Kalibr, 3M14 Biryuza (Бирюза, turquoise), (NATO codenames SS-N-27 Sizzler and SS-N-30A), 91R1, and 91RT2, is a family of Russian cruise missiles developed by the Novator Design Bureau (OKB-8). There are ship-launched, submarine-launched and air-launched versions of the missile, and variants for anti-ship, anti-submarine and land attack use. Some versions have a second propulsion stage that initiates a supersonic sprint in the terminal approach to the target, reducing the time that target’s defense systems have to react, while subsonic versions have greater range than the supersonic variants.
