The 9M113 Konkurs (contest) SACLOS (Semi-Automatic Command to Line of Sight) wire-guided Anti-tank missile of the Soviet Union. Its NATO reporting name is AT-5 Spandrel.
The missile is designed to be fired from vehicles, although it can also be fired from the later models of AT-4 Spigot launchers.
It is an
integral part of the BMP-2, BMD-2 and BRDM-2 vehicles. The missile is
stored and carried in a glass reinforced plastic container/launch
It is quickly accelerated to 200 m/s by its solid fuel motor.
This initial high speed reduces the deadzone of the missile, since it
can be launched directly at the target, rather than in an upward arc.
The missile spins in flight at between 5 and 7 revolutions per second.
The system has an alarm that activates when it detects jamming from a system like Shtora. The operator can then take manual control, reducing the missile to MCLOS.
The SACLOS guidance system has
many benefits over MCLOS. Accuracy of the system is quoted in some
sources as 90%, though its performance is probably comparable to the
TOW or later SACLOS versions of the Sagger.
