Lists on the subject |
The XM1111 Mid-Range Munition (MRM) was a precision-guided ammunition for the Rheinmetall 120-mm smooth-barreled cannon , the variant of which is known by the US armed forces as the M256 . It was developed to meet the requirements of the Future Combat System for "non-line of sight" tank ammunition. The development of both versions was canceled in 2009 together with the Future Combat Systems.
technology
MRM-KE acts like a bullet through direct hits. The ammunition can be fired both directly and indirectly. Until it reaches the target area, the projectile flies on a ballistic trajectory and activated until the final approach a rocket engine to supersonic fast to be (up to Mach 4). Together with the small thrust nozzles for quick course corrections, on the one hand the kinetic energy of the penetrator is to be increased, and on the other hand, distance-active protective measures are to be circumvented. A passive laser sensor and an active radar system, which can also detect targets autonomously ( fire-and-forget ), are used for target acquisition .
The MRM-CE works on the same principle, except that instead of the millimeter wave radar, an imaging infrared seeker is integrated. Due to the shaped charge, it also acts against lightly and unarmored targets (positions, buildings, vehicles).
The projectiles can be brought precisely to the target with a laser target marking, for example by a forward observer. If an enemy tank is to be attacked, the laser target marker can also be aimed next to the vehicle. The ammunition automatically switches to the identified target that is closest to the laser point. In this way, the opposing laser alarms are not triggered.
