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
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.
The MRM-KE (Mid-Range Munition - Kinetic Energy) is an implementation of the MRM under development by Alliant Techsystems
, Lockheed Martin
, BAE Systems
and HR Textron
The missile/projectile is designed to be used as a high-velocity
penetrator for line-of-sight and beyond-line-of-sight shots. In line of sight, it would operate using laser guidance
or a millimeter wave
seeker. In BLOS, the shell would be fired in a ballistic arc, and would seek out its own targets.
The missile uses a kinetic energy penetrator
to penetrate enemy armor. This effect is improved by a rocket motor
that speeds the munition up. It steers with impulse thrusters.
MRM-KE uses technology developed as part of the X-Rod... Read More
