The G5 is a proven, reliable and accurate 155 mm long-range gun with an auxiliary power unit. The auxiliary power unit provides hydraulic power for easy and rapid deployment, giving the gun a self-propelled capability for tactical movement. The G5 system has been developed for modern warfare. Continuous feedback to design engineers from military operations, and intensive testing under all possible conditions, has resulted in a gun that is not only immensely practical, but also extremely reliable and user-friendly.

Main Weapon
• 45 Calibre Autofrettaged Barrel
• Semi-automatic Screw-type Breech
• Recoil with variable recoil length

Loading System
• Loading tray
• Pneumatic piston-action rammer
• Loading at all elevation angles

Sighting and Laying
• Telescopic sight for direct fire to 3 000 metres
• Trunnion-mounted optical panoramic sight with
compensating mechanism for trunnion cant
• Aiming posts and beta lights storage on gun

Gun Control
• Pneumatic equilibrators with adjustment for temperature
variations
• Elevation and traverse gearboxes with handle wheels
• Traverse clutch for rapid traverse of the barrel from
travelling to firing position

Bottom Carriage
• High-strength steel carriage with split trails
• Four driving wheels on walking beam suspension
• Two trail steering wheels when self-propelled
• Self dig-in spades on split trails
• Large, hydraulically operated stabilising platform
• All gun equipment mounted on trails
• Barrel clamps for travelling and firing position

Auxilliary Power Unit
• 59 kW air-cooled four-cylinder diesel engine
• Primary hydraulic pump for propulsion
• Separate hydraulic pump for deployment
• 102 litre fuel tank

Hydraulic System
• Hydraulic opening/closing of split trails
• Hydraulic lowering/lifting of trail wheels
• Hydraulic steering of trail wheels
• Hydraulic lowering/lifting of stabilising platform

Redundancy
• In the event of a power unit failure, the G5 can be slaved
from another gun, gun tractor or can be operated by
means of a hand pump

The G5, together with its integrated logistics system, was developed in the context of an integrated artillery system as fielded by the Denel Group.

As a result, the G5 can be offered either alone or, more often, as part of a complete package – depending on the particular needs of the client.

Ammunition

A comprehensive and flexible ammunition ballistic system has been developed with the G5. This includes the following:

• Extended range full-bore projectiles of explosive,
cargo and practice types, all ballistically matched
and with field-fittable base bleed units.

• Velocity Enhanced, Long Range Artillery Projectiles
which extend the maximum range with at least 30%.

• A five-zone combustible-case modular propelling
charge system, based on cool-burning propellants,
ensure a long barrel life of more than 6000
standard charges.

• Compatible fuzes of direct action, electronic time or
proximity types, all suitable for full charge and
maximum range application.

Related Equipment

• Command and fire control systems
• Meteorological systems
• Observation systems
• Communication systems (for both voice and data)
• Logistic support vehicles
• Ammunition vehicles
• Gun tractors

Integrated Logistics Support (ILS)

A complete integrated logistics support package is available. The ILS is normally tailored to a specific environment and application, and takes into account the capabilities of the user’s existing support infrastructure. The package might include:

• Equipment and accessories carried with the gun or at higher echelons.
• Operating, maintenance and workshop repair manuals and illustrated parts catalogues.
• Spare parts and assemblies, and tools and equipment to support everything from first-line to base workshop repair and maintenance, including complete overhauls and rebuilds.
• Operational and technical training at all levels.
• Field support.
