AT-5 Spandrel missile |
The
AT-5 Spandrel is the
NATO reporting name for the
9M113 Konkurs (Contest)
SACLOS wire-guided Anti-tank missile of the
Soviet Union.
The
AT-5 Spandrel was developed by the Tula Machinery Design Bureau (Tula KBP). Development began in 1962 with the aim of producing the next generation of
SACLOS ATGM's, for use in both the man portable role and the tank destroyer role. The
AT-5 was developed alongside the
AT-4; both missiles use similar technology, only differing in size.
There was some speculation that the missiles where based on the
Euromissile HOT/
MILAN - which employ similar concepts.
The missile entered service in
1974.
Iran began producing a copy the
Towsan-1/M113 sometime around 2000.
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 tube.
The system uses a gas generator to push the missile out of the launch tube. The gas also exits from the rear of the launch tube in a similar manner to a
Recoilless rifle. The missile leaves the launch tube at 80 m/s. 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 launcher tracks the position of an incandescent
infrared bulb on the back of the missile relative to the target and transmits appropriate commands to the missile via a thin wire that trails behind the missile. 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.
