Rheinmetall’s South African subsidiary Rheinmetall Denel Munition and Northrop Grumman signed a 10-year strategic partnership agreement to this effect in February 2021. During this period, the two companies plan to cooperate to offer forward-looking ammunition technology to the international market, including the United States, to support future artillery operations. 

The partnership will focus on achieving an enhanced range 155mm artillery round fitted with an integrated M1156 precision guidance kit (PGK) and developing a new 155mm projectile with an improved integrated propulsion system.
