In 2008, the Australian Defence Force made a US Foreign Military Sales request for 57 M777A2s worth an estimated US$248m. M777A2 vs legacy M198 Īustralian soldiers firing an M777A2 during a training exercise in 2016 The furthest hit from an Excalibur ammunition by the United States Army was 30 km (19 mi) in Iraq. This was the longest operational shot in the history of the M777 howitzer, and the longest operational tube artillery shot in history for the Marine Corps. In June 2012, Golf Battery, 2nd Battalion, 11th Marines, out of Camp Pendleton, California, fired the M982 Excalibur against insurgents at a range of 36 km (22 mi) in Helmand Province, Afghanistan. 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 m (33 ft) of their target, suggesting a circular error probable of 5 m (16 ft). This almost doubles the area covered by a single battery to about 1,250 km 2 (480 sq mi). The M777 may be combined with the M982 Excalibur GPS-guided munition, which allows accurate fire at a range of up to 40 km (25 mi).

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 Leonardo MW with components of the Indirect Fire Control Software Suite (IFCSS) built by the Firepower team in the Canadian Army Land Software Engineering Centre. 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. The minimal gun crew required is five, compared to a previous nine, although the normal crew is eight minimal emergency crew rate of fire is decreased.
The M777 can be transported by helicopter sling-load, transporter aircraft such as the Lockheed C-130 Hercules, or towed by air-braked vehicles weighing over 2.5 tonnes (5,500 lb), such as the FMTV and MTVR medium vehicles. The gun barrel serves as the towing bar, with the connecting ring forged as a projection of the muzzle brake. Much of the weight reduction is due to the extensive use of titanium. The M777 now uses about 70% US-built parts including the gun barrel, which is manufactured at the Watervliet Arsenal. Upon taking over responsibility for the weapon BAE 'Americanised' to a large degree the construction and assembly through its US-based BAE Systems Land and Armaments group. VSEL was bought by BAE Systems after the UFH prototypes had been manufactured and demonstrated, consequently BAE became responsible for future design refinements and renamed the gun 'M777'. The M777 began as the Ultralight Field Howitzer (UFH), developed by Vickers Shipbuilding and Engineering's (VSEL) Armaments Division in Barrow-in-Furness, UK. US Marine gunners test fire an M777 howitzer. Final integration and testing of the weapon is undertaken at BAE's facility in Hattiesburg, Mississippi.
Prime contract management is based in Barrow-in-Furness in the United Kingdom as well as manufacture and assembly of the titanium structures and associated recoil components. The M777 is manufactured by BAE Systems' Global Combat Systems division. It made its combat debut in the War in Afghanistan. It is used by the ground forces of Australia, Canada, India, Saudi Arabia, Ukraine and the United States.
