General Dynamics Ordnance and Tactical Systems, a business unit of General Dynamics, and BAE Systems have successfully demonstrated a tactical version of their 81mm Roll Control Guided Mortar (RCGM) at Yuma Proving Grounds, Ariz., in January. Sixteen rounds were tested in total, all of which guided to within an average miss distance of approximately seven meters from the target at ranges from 980 meters to 4,000 meters. The tactical configuration of the RCGM used the current UK L41 high explosive mortar round and a six-increment propulsion charge system produced by BAE Systems. The guidance package developed by General Dynamics consists of a GPS receiver, standard M734A1 multi-option fuze components and the company's patented Roll-Controlled Fixed Canard (RCFC) control system.
