Mobile Mortar Systems


Developed by RUAG

RUAG of Switzerland have developed an autonomous, smoothbore, recoiled 120 mm mortar system, designed for installation on mobile platforms such as light APCs and trucks. Among the platforms tested were Mowag 8x8 Piranha and M-113. The Bighorn system can fire all types of 120mm mortar ammunition, including guided projectiles such as STRIX and Cargo munitions.

The system is designed for autonomous operation, including integral navigation, positioning and fire control capabilities. When fully configured for autonomous operation, Bighorn can deploy into a firing position, fire and leave quickly before being intercepted by enemy counterfire.
