RUAG Defence has developed an enhanced version of the M109 155 mm self-propelled (SP) artillery system aimed at the export market. The company has already upgraded 348 Swiss Army M109sto the Pz Hb 88/95 standard, which represent the only SP artillery deployed by the Swiss Army. Among the improvements are a modified turret and the use of locally manufactured 155 mm/47 calibre chrome plated ordnance in place of the original 155 mm/39 calibre type. This offers an extended range and has a burst rate of fire of three rounds in 15 seconds due to the installation of a flick rammer. RUAG Defence can also provide a crew training simulator (CTS) and video-assisted training programme (VAT) to train the upgraded M109/47 crews.
