Abstract:
1. A field gun comprising: a chassis, a barrel defining a barrel axis and having a traverse range and an elevation range, a cradle supporting the barrel, the barrel being attached to the cradle to allow sliding engagement, a trunnion joint for enabling pivoting in at least two axes, the joint connecting the cradle to the chassis, a first linear actuator, extensible along a first linear actuator axis, pivotally attached to the chassis by a first chassis joint and pivotally attached to the cradle by a first cradle joint, and a second linear actuator, extensible along a first linear actuator axis, pivotally attached to the chassis by a second chassis joint and pivotally attached to the cradle by a second cradle joint, wherein a first combination of first linear actuator and second linear actuator actuation varies the traverse, and a second combination of first linear actuator and second linear actuator actuation varies the elevation.
