9M113 Konkurs

The 9M113 Konkurs, known to NATO as the AT-5 Spandrel, is a Soviet wire-guided anti-tank missile that uses semi-automatic command to line of sight guidance: the gunner keeps the sight on the target while the launcher tracks an infrared bulb on the back of the missile and sends steering commands down a thin trailing wire. It was developed by the Tula Machinery Design Bureau as a heavier successor to the 9K111 Fagot, shares that missile's launchers and looks very similar apart from a slight bulge at the end of its tube. The original single-charge warhead can penetrate about 600 millimetres of rolled homogeneous armour, and the later tandem-warhead Konkurs-M, adopted in 1991, raises that to roughly 750 to 800 millimetres. The missile entered service in 1974, is carried on the BMP-2, BMD-2 and BRDM-2, and can also be fired from ground launchers. Iran bought a licence in 1991 and later built a copy called the Tosan, and the system has been exported to dozens of armies and used by several non-state groups.
