Propellant charge M11 Zone 10

Propellant charges M11 Zone 10 from the Serbian manufacturer “Yugoimport” are used in 155 mm artillery systems and are designed to provide long-range firing.

Characteristics:

1. Type: Non-adjustable, single-use charges for 155 mm howitzers.
2. Configuration: The M11 charges have a fixed configuration, with no option to adjust them for different ranges.
3. Additives: These charges contain additives such as lead foil to remove copper oxide fouling and potassium sulfate to reduce the visibility of the muzzle flash.

M11 is a unitary Zone 10 propellant charge for 155 mm howitzers that allows firing to distances of up to 39 km with the projectiles ERFB Mk 10/2 and ERFB-BB.

The charge consists of a combustible case, an igniter and a bundle of propellant sticks. The case is made of kraft paper, which burns up after firing. The igniter contains black powder and CBI to ignite the propellant sticks. The sticks have a low burning temperature, which extends barrel life and reduces flash visibility. To protect the barrel from copper oxide, the bundle of propellant sticks is wrapped in lead foil. M203A1 is a modern and effective charge for artillery.

The design contains granular propellant in a white bag. The charge casing is sewn from fabric and laced along its entire length, which provides rigidity and structural stability to the assembled charge.
