The Umkhonto (Xhosa: Spear) is a family of vertical launch system, surface-to-air missiles developed by Denel Dynamics. Umkhonto is designed to be a modern, short to medium-range missile, with an all-weather launch capability. Operating at supersonic speeds, the Umkhonto utilises infrared homing technology to provide point and limited local air defence against multiple attacks of aircraft and missiles. Umkhonto is available in three variants, a short-range infrared homing (Umkhonto-IR), a medium-range infrared homing (Umkhonto-ER-IR) and a beyond-visual-range radar homing version (Umkhonto-R).
