The M777 lightweight 155-mm towed howitzer is lighter and smaller, yet more powerful than any gun of its kind. The M777 weighs 9200 pounds compared to the M109 Howitzer at 49,940 pounds, making it highly mobile and easily transportable by C130 aircraft, helicopter or a truck of at least 2.5 tonnes.
It can be equipped with a digital fire control system and loaded with precision-guided munitions that use location data from Global Positioning System (GPS) satellites and an inertial navigation unit to steer precisely to the target. This gives the artillery the ability to destroy targets with increased accuracy, leading to less collateral damage. The M777 can also be combined with the new Excalibur GPS-guided munitions, which allow accurate fire to 30 km.
The M777 provides close and deep fire support without sacrificing range, stability, accuracy or durability. It is equipped with a highly advanced Digital Gun Management System which enables the crew to destroy targets in a very precise manner at all range distances.
