The M777 is a solid howitzer from British production mm with a caliber of 155th The manufacturer is BAE Land Systems . It is used by the United States Armed Forces and tested in the United Kingdom .
The first American unit in which the M777 replaced the M198 was the 3rd Artillery Battalion of the 11th Regiment of the 1st Marine Division of the United States Marine Corps in 2005 . By early 2010, the M777 had largely replaced its predecessor.
The howitzer can fire the M982 Excalibur and M795 GPS-guided projectiles . The latter uses a special course corrected fuse, "Course Correcting Fuze" (CCF) and was developed by United Defense in collaboration with Bofors Defense, Rockwell Collins and BT Fuze. This ammunition enhances the effect of existing guns almost to the point of impact capability, as it is required in combat situations. At the Yuma Proving Ground firing range, a spread of only 50 meters was achieved at a distance of 14.5 kilometers. For this purpose, the detonator is programmed with the target coordinates by a laptop immediately before it is fired.
In addition to the US armed forces, the Canadian armed forces have ordered 37 howitzers, the Indian armed forces 145 howitzers and the Australian Defense Force 35 howitzers.
As part of the ERCA (extended range cannon artillery) program, the howitzer is to be modernized and its range increased significantly. In tests with an extended barrel with a 58 caliber length (L / 58), a shooting distance of up to 70 kilometers should be achieved.
