   The XM1203 NLOS-C or Non-Line-Of-Sight Cannon. This artillery system uses technology from the cancelled XM2001 Crusader. The NLOS-C system is a part of proposed Future Combat Systems development. It was planned to replace the M109A6 Paladin self-propelled howitzers. The first prototype was completed in 2008. However the NLOS-C never reached production due to funding problems and other reasons. Some of its technologies were later used on the M109A7 howitzer.

   The NLOS-C is fitted with a fully automated 155-mm / L38 howitzer. It includes autoloader from the cancelled Crusader, which eliminates physical handling of ammunition. The XM1203 fires rounds at sustained rate with a push of a button. Maximum range of fire with standard projectile is 30 km. The XM1203 NLOS-C provides precision attack of point and area targets. This artillery system is capable of multiple round simultaneous impact firing. The XM1203 is also capable of firing precision guided munitions, such as the M982 Excalibur rounds. Estimated maximum rate of fire is about 10 rounds per minute.

   The NLOS-C incorporates active and passive protection systems, including specially designed ceramic armor and an RPG protection system to enhance crew and platform survivability against all types of battlefield threats. It is also fitted with an NBC protection system.

   Vehicle has a crew of two. Crew was reduced due to full automation of the system. Refueling of this artillery system is arranged automatically. Reloading also do not requires for crew members to step outside the vehicle.

   The NLOS-C uses tracked Future Combat System family chassis. This chassis was ment to have 75-80% commonality. The NLOS-C is powered by a diesel engine and hybrid electric propulsion system, designed to improve system mobility, reduce fuel consumption and offer silent mobility capabilities. The NLOS-C can be airlifted by the Airbus A400M and similar transport aircraft.
