Abstract: A light weight field howitzer includes a barrel which is supported by a cradle constructed from hollow members and which is pivotally mounted about a trunnion bearing secured to a chassis. The trunnion bearing lies on the barrel axis and is positioned beyond the limit of maximum recoil of the barrel. Front stabilisers and rear trail support legs are provided to spread the load of the howitzer and spades are rigidly secured to the chassis. The howitzer includes a single hydraulic accumulator arrangement constituting a combined recoil buffer and recuperator system. A barrel elevating means is provided comprising a geared manual means assisted by a precompressed gas system.

Abstract: A spade assembly for use on an artillery vehicle compensates any gaps which would otherwise be formed between a ground supporting portion of the spade assembly and the soil. The length of the spade assembly is advantageously compensated to maintain the spade assembly in firm contact with the soil. This can increase the accuracy in the weapon in firing, and avoid violent displacement of the gun which can be caused when the spade assembly is not maintained firmly engaged with the earth.
