A 9M117 missile

The 9M117 Bastion is a Russian laser beam-riding anti-tank missile. It is used in a number of separate weapon systems, including the 9K116-1 Bastion missile system (AT-10 Stabber), 9K118 Sheksna (AT-12 Swinger), Kastet and the 3UBK12 fired from the BMP-3. The 100 mm projectile entered service in 1981.^[1]

Development

The 9K112 Kobra (AT-8 Songster) was the first Soviet tube fired anti-tank missile to enter service; however, it was only deployed in limited numbers to front line units. Development work began in the late 1970s on a third generation of guided projectiles that would use laser guidance rather than radio command links. The guidance system was developed by Igor Aristarkhov, and the missile was developed by Petr Komonov.^[2] The Bastion was developed firstly as a relatively cheap missile fired from towed MT-12 100 mm smoothbore AT-guns.^[1] The 9M117 missile was part of the 3UBK10 round and the whole weapon system was designated 9K116 Kastet. A laser guidance device was seated on a tripod next to the gun.^[1] The system was commissioned in 1981.^[1]

During development of the 9K116 system, it was recognized that it could enhance the long range firepower of the older T-55 and T-62 tanks. The system for the T-55's D-10T 100 mm rifled gun was designated 9K116-1 Bastion (3UBK10-1 round); and for the T-62's U-5TS 115 mm smoothbore gun, 9K116-2 Sheksna (3UBK10-2 round).^[3] The 9M117 missiles were identical, as in the towed version; however, the 115 mm version had additional guiding rings.^[3] They were commissioned in 1983.^[3] Then, the 9K-116-3 system was developed for the 100 mm rifled^[4] gun of the BMP-3 infantry fighting vehicle, commissioned in 1987. Similar systems, with larger caliber 9M119 Svir missiles, were developed for the 125 mm guns of the T-72 and T-80 tanks.

Description

The 100 mm round resembles a normal 100 mm anti-tank round, and is loaded and fired in the same fashion. The round uses a reduced explosive charge to launch the projectile out of the barrel of the gun at around 400 to 500 m/s. After leaving the gun barrel, a small cover falls away from the window on the rear of the missile. The rocket motor ignites 1.5 seconds after firing the missile, and it burns for 6 seconds.

The projectiles use laser guidance. A cone of laser light divided into sectors is projected from the launching tank/vehicle/gun, each sector having a different frequency or modulation. The missile has a small window in the rear with a sensor to detect the modulation of the light. Using this modulation, the missile steers itself, maintaining its position in the cone. The laser beam-riding guidance system is smaller than a radio command one, and cheaper and simpler than semi-active laser guidance. The missile is also not prone to radio or optical jamming.^[1] On the other hand, a target has to be tracked by laser sight all the time, and the system can not be reliably used on the move.^[3]

The missile's flight time to 4,000 meters is approximately 12 seconds. After 26 to 41 seconds, the missile self-destructs.
