A self-propelled gun system () comprising a chassis () to which is mounted a gun barrel () having a gun barrel axis (). The system also has a chassis suspension system () comprising a first wheel arm () extending away from the chassis () to a first wheel (), the first wheel () being rotatably mounted on the first wheel arm (), the first wheel () configured for engagement with, and travelling along, a support surface () to support the chassis () a distance (Dz) apart from the support surface (). There is also provided a recoil mitigation system () comprising a recoil support leg () which extends away from the chassis () to a foot end (), the foot end () operable to engage with the support surface () during firing of a projectile () from the gun barrel (). The foot end () of the recoil support leg () is operable to be spaced apart from the support surface () when the gun system () is in transit. The recoil support leg () is configured to react against recoil force (Fr) in the z-axis from the firing of a projectile () from the gun barrel (). The recoil mitigation system () further comprising a wheel brake control device () configured for applying a braking force to the chassis first wheel () after the firing of a projectile () from the gun barrel () and after the rotatable first wheel () has started rotating along the support surface () in response to the firing of a projectile () from the gun barrel ().

Self-propelled gun system

A blast attenuation device () for a gun tube (). The blast attenuation device () has a first wall section () which defines a first chamber (), which extends from an inlet end () having an inlet aperture () to an outlet end () having an outlet aperture (). The blast attenuation device () also has a second wall section () which defines a second chamber (), which extends from an inlet end () having an inlet aperture () to an outlet end () having an outlet aperture ().

Blast attenuation device

A muzzle brake () for a gun tube () defining a bore () centred on a longitudinal axis (). The muzzle brake () comprises a top plate () and a bottom plate (). A first wall section (), a second wall section () and a third wall section () extend from the top plate () to the bottom plate ().The second wall section () extends from the first wall section () to a first baffle (). The third wall section () extends from the second wall section () to a second baffle (). The second wall section (), top plate () and bottom plate () converge towards the longitudinal axis () and the first baffle (), such that the second wall section (), top plate (), bottom plate () and first baffle () define a first compression cone (). The third wall section (), top plate () and bottom plate () converge towards the longitudinal axis () and the second baffle () such that the third wall section (), top plate (), bottom plate () and second baffle () defines a second compression cone ().
