XM-501 NLOS - Non Line Of Sight Missile System
The XM-501 Non Line Of Sight Launch System (NLOS-LS) will begin fielding with the first Brigade Combat Team in 2011. The system provides a unique, flexible, platform-independent precision engagement system, empowering light and heavy brigades with immediate and responsive precision fires against moving and stationary targets and against surface targets at sea. The system employs the Precision Attack Missile (PAM), designed to follow preprogrammed flight paths and in-flight target updates.

Using the two-stage boost-sustain rocket motor and GPS/INS to navigate to the designated target area, PAM can reach targets at a maximum range of 40 km. At close proximity to the target the missile employs automatic target acquisition and terminal guidance system, using the uncooled imaging infrared or semi-active laser seeker, to hit the target with high precision. The PAM can also be directed to hit a specific location, utilizing GPS/INS guidance to navigate to the predefined grid coordinates. The missile is loaded with high explosive shaped charge with fragmentation wrap, defeating armored and soft targets alike. Each Command Launch Unit (CLU) contains 15 ready to fire missiles and one computer and Communications System (CCS) handling the system's networking and control.
Operating as networked assets, CLUs are operated as unattended units, remotely controlled directly by the supported unit. The CLU can fire missiles individually or dispense all missiles at a rapid succession in 5 seconds intervals. Being platform independent, loaded CLUs can be positioned at forward operating bases or pre-positioned in forward areas to support an unfolding operation. CLUÂ can be moved on tactical vehicles (HMMWV) or medium trucks (FMTV), sling loaded under UH-60s or air-dropped form C-130.
