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:

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:
