The M198 is a medium-sized, towed 155 mm artillery piece, developed for service with the United States Army and Marine Corps . It was commissioned to be a replacement for the World War II-era M114 155 mm howitzer . It was designed and prototyped at the Rock Island Arsenal in 1969 with firing tests beginning in 1970 and went into full production there in 1978. It entered service in 1979 and since then 1,600 units have been produced.
44-503: The M198 was replaced in US and Australian service by the M777 howitzer . The M198 155 mm howitzer weighs less than 16,000 pounds (7,300 kg), allowing it to be dropped by parachute or transported by a CH-53E Super Stallion or CH-47 Chinook . The M198 is towed by a 5-short-ton (4.5 t; 4.5-long-ton) truck that is used to carry the nine person crew with supplies and ammunition; it

BAE stated that month that it was discussing with the United States restarting production of the weapon, after good performance in Ukraine and lower cost of operation caused other nations to ask about purchasing it. In October 2022, Ukraine was given an additional 16 M777 by the US, and as of October 2022 had at least 170. In November 2022, according to U.S. and Ukrainian officials,

The M777A1 and M777A2 use 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 Canadian M777 in conjunction with
308-551: A third of the roughly 350 Western-made howitzers (including 142 M777s given by the US) donated to Ukraine are out of action at any given time. Those weapons are wearing out after months of overuse, or being damaged or destroyed in combat. As of late May 2023, at least 52 M777s were reported to have been destroyed or damaged. One Ukrainian crew claims to have fired 6,000 rounds through their M777. During this time they have had four barrel changes. All of these barrel replacements occurred before

BAE US subcontractors and their related components/activity as planned in 2001 : With a weight of 4.2 t (4.1 long tons; 4.6 short tons), the M777 is 41% lighter than the 7.154 t (7.041 long tons; 7.886 short tons) M198 howitzer it replaces. Much of the weight reduction is due to the extensive use of titanium . The gun barrel serves as
704-529: Is transported tail first. The gun tube can be rotated over the howitzer's trail legs to reduce its length, though this requires removal of the muzzle brake , or left in the firing position for faster deployment. When firing, the weapon is lowered onto its baseplate rather than anchored to the ground, allowing for rapid emplacement. The breech is operated manually via a screw type mechanism that rests low in an ergonomic position. The M198 fires separate-loading (non-fixed or semi-fixed) ammunition and can be loaded with
748-769: The Battle of Panjwaii when a small number of rounds were used to huge effect on Taliban elements retreating from the battle area. Many of the 72 reported killed during the heaviest period of fighting were due to artillery fire from only two of these guns. In late fall of 2006, the Canadian M777 howitzers were equipped with the Digital Gun Management System (DGMS), which greatly improved accuracy and led to these guns being used for short range close support of Canadian and US ground forces. They proved so successful that an order for an additional six guns

This almost doubles the area covered by a single battery to about 1,250 km (480 sq mi). 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
