A video of the M777 howitzer artillery system use by the US military and is considered a real deadly killer. The M777 howitzer is a towed 155 mm artillery piece, successor to the M198 howitzer in the United States Marine Corps and United States Army. The M777 is also used by the ground forces of Canada and Australia. It made its combat debut in the War in Afghanistan.
The M777 is manufactured by BAE Systems' Global Combat Systems division. Prime contract management is based in Barrow-in-Furness in the UK as well as manufacture and assembly of the titanium structures and associated recoil components. Final integration and testing of the weapon is undertaken at BAE's facility in Hattiesburg, Mississippi.[3]
Design
The M777 began as the Ultralight-weight Field Howitzer (UFH), developed by VSEL's armaments division in Barrow-in-Furness, United Kingdom. This company was bought by BAE which ended up responsible for design, construction and assembly (through its US-based, BAE Systems Land and Armaments group). The M777 uses about 70% US-built parts including the gun barrel manufactured at the Watervliet Arsenal.
The M777 is smaller and 42% lighter, at under 4,100 kg (9,000 lb), than the M198 it replaces. Most of the weight reduction is due to the use of titanium. The lighter weight and smaller size allows the M777 to be transported by MV-22 Osprey, CH-47 helicopter or trucks with ease to provide increased mobility and more compact storage over the M198. The minimal gun crew required is five, compared to a previous nine.[4]
The M777 uses a digital fire-control system similar to that found on self-propelled howitzers such as the M109A6 Paladin to provide navigation, pointing and self-location, allowing it to be put into action quickly.[citation needed] The Canadian M777 in conjunction with the traditional "glass and iron sights/mounts" also uses a digital fire control system called the Digital Gun Management System (DGMS) produced by SELEX with components of the Indirect Fire Control Software Suite (IFCSS) built by the Firepower team in the Canadian Army Land Software Engineering Centre.[5] The SELEX portion of the system, known as LINAPS, had been proven previously through earlier fielding on the British Army Royal Artillery's L118 Light Gun.[6]
The M777 may be combined with the Excalibur GPS-guided munition, which allows accurate fire at a range of up to 25 miles (40 km). This almost doubles the area covered by a single battery to about 5,000 km2. Testing at the Yuma Proving Ground by the US Army placed 13 of 14 Excalibur rounds, fired from up to 24 kilometres (15 mi), within 10 meters of their target,[7] suggesting a circular error probable of about five meters.
Golf Battery, 2nd Battalion, 11th Marines, out of Camp Pendleton, Calif., dropped the 155 mm M982 Excalibur round on insurgents 36 kilometers away — more than 22 miles — in Helmand province, marking the longest operational shot in the history of the M777 howitzer. This record shot, made in June 2012, was also the first time the M777 had fired the Excalibur in combat.[8]
In 2014 the US military began fielding several upgrades to their M777 howitzers including new liquid crystal display units, software updates, improved power systems, and muzzle sensors for onboard ballistic computing. Future upgrades include a touchscreen Chief Section Display, a new Mission System Computer, and a digital radio.[9]
Variants[edit]
M777 – gun with optical fire control
M777A1 – digitisation upgrades with the addition of an on-board power source, satellite global positioning, inertial navigation, radio, Gun Display Unit (GDU) and Section Chief Assembly (SCA).
M777A2 – Block 1A software upgrade. Addition of an Enhanced Portable Inductive Artillery Fuze Setter (EPIAFS) to enable Excalibur and precision munition compatibility.[10][11]

Army[edit]
18th Field Artillery Brigade (Airborne) at Fort Bragg, North Carolina was the initial Army test bed unit for the XM777 Lightweight 155mm Howitzer which included 1st and 3rd Battalions 321st Field Artillery Regiment. Gun Section 2, 2nd Platoon (5th Section) Bravo Battery, 2–11th Field Artillery (FA) was the first US Army unit to fire the M777A2 in combat at 08:23 (Baghdad Time) on 2 January 2008 in support of Operation Iraqi Freedom. 2–11 FA deployed December 2007 with 2nd Brigade Combat Team (BCT), 25th Infantry Division out of Schofield Barracks, Hawaii. In June 2007, the M777 in its A2 configuration was assigned to the U.S. Army's 3rd Battalion, 321st Field Artillery Regiment. 3-321 FA deployed to Afghanistan in support of Operation Enduring Freedom in December 2007 and has become mission capable since January 2008 making 3–321 FA the first U.S. Army unit to utilise the M777 in combat in support of Operation Enduring Freedom. In April 2008, the M777 was deployed for testing with the 2nd battalion,
