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 HEAT 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 covered system design and development. The Mid-Range Munition was cancelled in 2009 along with Future Combat Systems.[1] MRM-KEThe MRM-KE (Mid-Range Munition-Kinetic Energy) was an implementation of the MRM under development by Alliant Techsystems, Lockheed Martin, BAE Systems and HR Textron.[2] The missile/projectile was 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 used a kinetic energy penetrator to penetrate enemy armor. This effect was improved by a rocket motor that sped the munition up. It steered with impulse thrusters. MRM-KE used technology developed as part of the X-Rod and XM1007 Tank Extended Range Munition (TERM) programs, both of which have been cancelled. [3][4]Timeline
MRM-CEThe missile/projectile was to be a high-velocity multiple-mission projectile for line-of-sight and beyond-line-of-sight shots. In line of sight, it would operate using laser guidance or an uncooled imaging infrared seeker (IIR). In BLOS, the shell would be fired in a ballistic arc, and would glide to seek out its own targets. The BLOS mission could be autonomous or use FO directed target designation. The MRM-CE uses a dual-mode MMW, imaging infrared (IIR) autonomous seeker or SAL is used to acquire and guide towards the target with high accuracy. The dual-mode seeker was developed and successfully demonstrated during a two-year, Army-managed science and technology program. MRM-CE refined seeker technology developed as part of the XM1007 Tank Extended Range Munition (TERM) program. For a beyond-line-of-sight mission, the chemical energy warhead was a better solution; with proven lethality against the primary target of threat armor, and better effects against the secondary targets of buildings, fortifications, and light armor than a less versatile kinetic energy penetrator.
