The Russian 3M-54 caliber ОКР Калибр and 3M-14 turquoise ОКР Бирюза are Russian surface ship and submarine-launched anti-ship and coastal AShM and LACM missiles developed by the Novator Design Bureau (OKB-8). Its NATO designation is "SS-N-27A" with the NATO codename of "Sizzler". Derived export versions are the 3M-54E and the 3M-54E1. The 3M-54E has a NATO designation, the SS-N-27B; (it does not have a NATO codename). The 3M-54 and 3M-54E, in their final stage, make a supersonic "sprint" to the target, reducing the time that target's defense systems have to react. The 3M-54E1 has the capability of subsonic speed in its whole flight. Its range is longer than that of the 3M-54E.
The name of "Klub" is used for export versions, the 3M-54E and 3M54E1.
