[citation needed] The first deliveries of M777A2 began in late 2010. [10] Depending on the year, contract and systems package, the M777 has been exported for individual unit costs including US$2.025million (in 2008) and $3.738million (in 2017)[11][12], The M777 began in 1987 as the Ultralight Field Howitzer (UFH), developed by Vickers Shipbuilding and Engineering's (VSEL) Armaments Division in Barrow-in-Furness, UK. [89], In May 2005, 3rd Battalion, 11th Marines, based at Marine Corps Air Ground Combat Center Twentynine Palms, became the first Marine unit to begin fielding the new M777.

Those weapons are wearing out after months of overuse, or being damaged or destroyed in combat. Read also:Switchblade: American kamikaze drones to protect Ukraine. The 155mm howitzer related efforts are all grouped together into a program known as Extended Range Cannon Artillery (ECRA), which has been ongoing since 2016. The base version weighs 48 kg and carries a 22-kilogram high-explosive warhead. The PIMs onboard power system harnesses technologies developed for the Non-Line-of-Sight Cannon (NLOS-C), a 155mm howitzer formerly developed for the Future Combat Systems Manned Ground Vehicles program, which was canceled in 2009. The electric drives from the NLOS-C are faster than the hydraulic drives used by previous self-propelled howitzers. Maximum range of fire is 30 km with standard HE-FRAG shells and 40 km with rocket-assisted shells. [14], With a weight of 4,200kg (9,300lb), the M777 is 41% lighter than the 7,154kg (15,772lb) M198 howitzer it replaces. While the individual shells may cost more, a single battery of howitzers at one firebase would suddenly be able to do what would've taken multiple bases in the past. Approximately 1,000 M777 155mm howitzers are in service with the US Army and US Marine Corps as of October 2018. The concept was copied from the Soviet 85mm SD-44 auxiliary-propelled antitank gun developed in 1954 and used by airborne forces. 580 guns were supplied to the Marines, and 421 to the U.S. Army and National Guard. It's Becoming a Problem for the Pentagon", "Attack On Europe: Documenting Ukrainian Equipment Losses During The 2022 Russian Invasion Of Ukraine", "M777 crew replaced the howitzer barrel four times due to overuse", "2 US soldiers killed in artillery mishap in Iraq identified", "82nd Airborne paratrooper dies in howitzer explosion at Fort Bragg", "Ten injured during artillery training at Fort Bragg", "Two US troops killed, 5 injured in northern Iraq in artillery incident", "Army Concerned Over Ban on Cluster Munitions, Land Mines", "Firebase Saham: A day in the life of joint-artillerymen securing the Iraq border", "DoD Orders 46 Additional M777 Howitzers", "Near ISIS front, U.S. Marine artillerymen 'fire every day'", "Marines in Iraq came under 'numerous' rocket attacks, commander says", "Marines have arrived in Syria to fire artillery in the fight for Raqqa".

India's Ministry of Defence cleared the proposal for buying 145 guns for US$660 million on 11 May 2012 through the US Government's Foreign Military Sales (FMS) process. The initial velocity of the projectile is 827 m / s. The howitzer has a maximum firing range of 24.7 km with standard projectiles and 30 km with EFRB (Extended Range Full Bore). The carriage consists of four extruded titanium tubes, a battery, two recoil cylinders and a balancing mechanism. The 155mm howitzer is the longest-ranged of the military's indirect-fire guns, able to hit targets up to 18 miles away. The longer the barrel is, the more it is liable to bend when troops fire the gun, especially with extended range ammunition using powerful propellant charges. A longer barrel allows expanding gases triggered by the shell powder to act upon the projectile for a greater period of time, increasing velocity. Glory to Ukraine! Partner countries are constantly working to help us with this problem by providing us with artillery shells of the required caliber from the reserves of the former Warsaw Pact countries. The PIM includes a sustained rate of fire of one round per minute and a maximum rate of fire of four rounds per minute. South Korean firm Hanwha Defense will join with UK suppliers to compete for the UKs Mobile Fires Platform programme, the project to replace the AS90. This was eventually adopted as the M41 Howitzer Motor Carriage and saw action in the Korean War. Similar to the M109A7, the 2S35 is reported to have a range between 40 and 80 kilometers.

All of these barrel replacements occurred before the limit of 2,500 rounds as they noticed accuracy was decreasing. In addition, Excalibur is resistant to GPS interference. PROJECTILE, 155MM: EXTENDED RANGE, DP, M864. The Hawkeye self-propelled howitzer is being proposed as an alternative to towed 105 mm howitzers.

The 39-calibre 155mm M284 cannon, which is fitted with an M182 gun mount, has a range of 24km using unassisted rounds or 30km using assisted rounds. Full production systems are fitted with the General Dynamics Armament Systems Towed Artillery Digitisation (TAD) system. The maximum towed road speed is 88km/h and the towed cross-country speed is 50km/h. U.S. Army Colonel John Rafferty, the director of the Long Range Precision Fires (LRPF) Cross-Functional Team (CFT), part of the Armys new Futures Command, explained the new range goal to reporters on Oct. 10, 2018, at the Association of the U.S. Armys (AUSA) annual exhibition in Washington, D.C. The U.S. Army is soliciting ideas for a single new howitzer to replace all of the towed 105mm and 155mm types in its Stryker-equipped and regular light infantry brigades.

Of course, this whole transition takes time and effort, it can not be done in one day. A contract for full-rate production of 495 systems was awarded to BAE Systems in April 2005, and the following month the USMC began fielding the M777 with the 11th Marines unit at Twentynine Palms in California. [19][20] The minimum gun crew required is five, compared to a previous nine. The longer-range cannon is also being supported by commensurate lethality upgrades such as the emergence of new rounds able to attack and destroy a wider sphere of targets. Once your account is created, you'll be logged-in to this account. The Ultralightweight Field Howitzer (UFH), designated M777 in the US, was selected to replace the existing inventory of M198 155mm towed howitzers by a joint US Army / Marine Corps initiative in 1997. The service says it is . [21] The normal crew is eight. ECRAs 29.49-foot-long barrel with humans for scale. When the service first created the LRPF CFT to coordinate all advanced artillery developments in 2017, the plan was to increase the range of 155mm howitzers to more than 60 miles. In recent years the Army has massively extended the range at which its GPS-guided precision rounds can attack, by architecting a first-of-its-kind Extended Range Cannon Artillery program. The howitzer can be towed by an air-braked 44 vehicle greater than 2.5t.

The gun fires separate-loading, bagged charge ammunition, with up to seven different propelling charges, from 1 (the smallest) to 7 (the largest). With this kind of scenario in mind, the U.S. Army and Raytheon are working on a newly configured tank-killing Shaped Charge 155m precision-guided artillery round as part of a large-scale strategic attempt to outrange enemies and destroy approaching enemy armored columns at safer standoff ranges. The projectile was inducted by the Indian Army in October 2019. The M777 now uses about 70% US-built parts including the gun barrel, which is manufactured at the Watervliet Arsenal.
