The 2K11 Krug (Russian: 2К11 Круг; English: 'circle') is a Soviet and now Russian medium-range, medium-to-high altitude surface-to-air missile (SAM) system. The system was designed by NPO Novator and produced by Kalinin Machine Building Plant. Its GRAU designation is "2K11." Its NATO reporting name is SA-4 Ganef, after the Yiddish (originally Hebrew) word גנבֿ meaning 'thief'; the name was used because the system resembled the Bristol Bloodhound.
