M87 100 mm antitank gun

The 100 mm antitang gun M87 is a typical towed artillery piece, designed for anti-armour engagements. As the gun was created by successful marrying of components of the 122 mm howitzer D30J and the 100 mm antitank gun T-12 (2A19-M), it features the best properties of these two weapons, namely:

  • The gun uses all types of ammunition for the 100 mm antitank gun T-12 and retains the original outer ballistics;
  • Its three-trailed carriage enables full circle field of action, quick transfer of fire and engagement of highly mobile armoured targets;
  • Folding the barrel over trails in traveling position ensures the weapon's high mobility, stability in transport and excellent terrain negotiating properties;
  • Comfortable and reliable tracking of moving targets as the gunner's seat is mounted on upper carriage;
  • Auxiliary wheels fitted to the trails enable easy movement about the firing position by forces of the crew and rapid setting up in combat position;
  • Advanced opto-electronic day/night fire control system and laser range finder ensure quick reaction time, day and night and in low visibility conditions, and high first round hit probability;
  • Reliable brakes and proper signal lights provide for safe towing over public roads

Fire control system

In addition to conventional sighting devices (passive day/night sight ON 100-M78, panoramic sight P-M78, range finder D100-M78, collimator K-M78), the gun is equipped with an opto-electronic day/night fire control control system which incorporates a laser range finder.

This fire control system enables:

  • Memorizing of all required data for four types of ammunition
  • Determining the target movement velocity
  • Target ranging,
  • Automatic sighting mark displacement in the field of view, taking into account ammunition type, current meteo-ballistic conditions, charge temperature, target speed and range and deviation of the projectile muzzle velocity.
