XM1111 Mid-Range Munition
The XM1111 Mid-Range Munition (MRM) is a 120 mm precision guided munition being developed for the Rheinmetall 120mm Gun (known as the "M256" in the US military) used by several Western tanks. It was also intended to fulfill a requirement for Future Combat Systems (canceled) for a long-range, Beyond Line of Sight tank munition.
The U.S. Army awarded two contracts in a competition to validate the requirement, one for a kinetic energy penetrator round (MRM-KE) and one for a chemical energy warhead round (MRM-CE).
In December 2007, Raytheon's CE-based concept was awarded the system-design-and-development contract to develop the round. Valued at $232.3 million, the 63-month contract covers system design and development.
