and networked information systems. Improvements in the refueling arrangements and automation of ammunition reloading reduced the amount of time spent on resupply and during which the gun would be unavailable for combat support. This also allowed the system to use a crew of two instead of five. The NLOS-C was among the heaviest of the eight MGV variants. In June 2003, the NLOS-C was projected to weigh 25.3 tons at essential combat capability and 29.2 tons at full combat capability. The NLOS-C had especially high commonality with the NLOS-Mortar vehicle. History BAE Systems developed a concept technology demonstrator testbed. BAE completed testing the demonstrator in early 2006. In May 2008, BAE revealed the first Non-Line-of-Sight Cannon prototype. Prototype 1 made its first public appearance on the National Mall, in Washington in June 2008. Eight prototypes were delivered to the U.S. Army's Yuma Proving Ground in Arizona by 2009. BAE produced five prototypes. In April 2009 Defense Secretary Robert Gates recommended that the MGV program be terminated. Congress had directed that the Army continue working on the NLOS-C as a separate initiative. In December, Pentagon acquisition chief Ashton Carter directed the Army to cancel the NLOS-C. Carter directed the Army to begin work on the Paladin Improvement Program (M109A7). The electric rammer from the NLOS-C and some of the electric drives were integrated into the M109A7.
