TM 9-1025-215-10 M777 Howitzer Operator’s Manual

The mm M Howitzer is the core strategic artillery system of the future, soon to become the NATO standard weapon in its class. The gun is already in high demand from nations worldwide, recognising the unique structure and capability of providing artillery support to early entry and rapid reaction forces. A revolutionary gun system meeting the demands of today’s security environment. The mm Lightweight Howitzer was originally developed as a private venture. In the spring of the project definition was completed.

Its objective was to have a weapon with the same range as the US Army’s M mm towed howitzer but weighing no more than 4, kg. The US Army was fully briefed on the system and agreed that if the company built a prototype of the system with its own money it would carry out a complete evaluation of the system.

In Septemberthe main board gave approval to build two prototypes of the system, which is today called the mm Lightweight Howitzer. Both were completed in late The complete upper part of the weapon was test fired at Eskmeals in June with a total of 50 rounds being fired at all elevations, 12 of which were zone 8S top charge.

Although the weapon was originally targeted at the US Army, the US Marine Corps took the initiative as it was looking for a lightweight mm system to replace all current mm and mm towed artillery systems. It also completed limited land mobility trials and airlift certification in single and split mode. At the end of Phase 1 the system was awarded limited live crew clearance for the US. Amphibious trials were carried out successfully at Little Creek.

These climatic firings were followed by air transportability split lift trials and km of land mobility trials on test tracks ranging from trails to Belgian blocks and included wading to a depth of 1.

The US then had a competition which involved extensive tests with the mm Lightweight Howitzer and the Light Towed Howitzer developed at the then Royal Ordnance facility at Nottingham. In the end the former was selected.

This company no longer has any involvement with the programme. The M, which while under development was called the XM, will m777 the current mm M towed howitzer which weighs 7, kg.

These have underwent an extensive series of tests in the US during which more than 10, rounds of ammunition have been fired. Barrow-in-Furness manufacture the upper cradle as well as the suspension and running gear.

The MA1 will be delivered over a four-year period starting in July and running through to October The US Army is expected to take delivery of systems and the US Marine Corpsas the replacement for the current in-service and much heavier mm M towed howitzer.

Marines from the 3rd Battalion, 11th Marine Regiment stationed at Twentynine Palms, California, were the first unit to receive the M This has a maximum range of 40 km and is accurate to 10 m. The MA2 also has a hard wired fuze setter which is located near the assistant gunner’s position and used to programme the Excalibur fuze prior to loading.

Excalibur can also be fired by other towed and self-propelled artillery systems with a modified fire control system.

Late in Canada took delivery of the six M mm lightweight towed artillery weapons and these were issued to the 1st Regiment Royal Canadian Horse Artillery.

In early howktzer were deployed by Canada to Afghanistan in support of operation Archer. This was the first operational deployment of the M Since then an additional six weapons have been supplied which brings the total up to As of early six of these were in Canada and six in Afghanistan.

The Canadian Army has a requirement for another 34 mm lightweight howitzers. Canada was the howigzer country to deploy the M in action. By earlyproduction of the MA2 was running at 18 units a month and production will continue to at least late Although the M uses advanced materials in its construction, it is claimed to be simple to operate and maintain under field conditions.

The conventional screw breech is howktzer operated and opens vertically. A derivative of the M49 firing mechanism ym mounted to the primer feed mechanism. The magazine has the capacity for 10 M82 primers.

To keep the weight down, extensive use has been made of extruded titanium alloy fabrications, designed by BAE Systems Land Systems, but subcontracted to other companies, as well as efficient structural design. Some of the parts perform two functions, for example the Horstman Defence Systems designed hydropneumatic suspension system also operates as a hydraulic jack. The cradle includes four extruded titanium tubes, an accumulator, two recoil cylinders and balancing gear.

The cannon tube assembly includes the cannon tube, muzzle brake, towing eye, primer feed mechanism and screw breech.


The carriage comprises two sub-assemblies, the body and the saddle. The body includes two forward stabilisers and two m7777 trails fitted with self-digging spades and dampers. Mounted on either side of the body is a hydrogas suspension unit fitted with stub axle and aluminium rimmed road wheels. A small hydraulic hand pump is installed at each wheel station to raise and lower the system into ym out of action.

A centrepost on the body receives the saddle, and a rack segment attached to the rear of the body engages with the saddle-mounted traverse gearbox enabling the saddle to be rotated through mils left and right. The saddle is fitted with a yoke-mounted roll screw and nut elevation gear actuated by handwheels on either side of the saddle. In the baseline model, a universal sight mount is fitted on the left side but provision is made for a second sight on the right side for customers requiring a two-sight system.

A loading tray is provided to the rear of the breech, which is opened automatically.

BAE Systems Land Systems is considering future options, which could include a flick rammer, but the aim for the present is to keep the weapon as simple as possible. When in the travelling configuration it is towed by its muzzle in a similar manner to the Russian howktzer D howitzer by any truck with a 2 tonne capacity or greater fitted with air-operated brakes.

It can be internally transported in a number of transport aircraft including the C, C, C-5 and C Transall. BAE Systems Land Systems has proposed a complete family of mm weapons based on the M, as well as the mm M with 39 calibre barrel now in production in the US. This requirement has now lapsed but m7777 are provided in the self-propelled gun and howitzers wheeled section as the prototype still exists.
