The new 130 mm gun is a precondition for the future tank, known as ‘Main Ground Combat System’ (MGCS) being developed by Germany. MGCS is currently being developed by Germany and France as a future replacement for the Leopard 2 and Leclerc main battle tanks, considering the increasing threat posed by Russian systems such as the Armata (T-14) MBTs.
Rheinmetall unveiled the new weapon at Eurosatory 2016.
The Norwegian company Kongsberg Defence & Aerospace AS and Finland's Patria Oyj have formed a teaming agreement to provide turreted mortar solutions for future U.S. Army mortar programs. Under this agreement the team will promote the turreted mortar and produce the 120mm Patria Nemo, turreted, remote-controlled mortar system in the US.
