Abstract: A towed howitzer interchangeable between a travelling mode and a firing mode, the towed howitzer being suitable for deployment on a ground plane, the towed howitzer includes: a barrel for firing a projectile, the barrel defining a barrel axis, a cradle for holding the barrel at an azimuth and an elevation, a mechanism for varying the elevation and the azimuth of the barrel and a front leg for supporting an aiming mechanism. The front leg includes a wheel intended for contacting the ground at a foremost ground contact point; a suspension mechanism for resiliently mounting the wheel and a restraining mechanism for selectively enabling the suspension. The howitzer includes a back leg for contacting the ground at a backmost ground contact point. The back leg includes a hinging for swinging the back leg out of contact with the round.

Abstract: A howitzer suitable for deployment on a ground plane, the howitzer comprising a barrel for firing a projectile, the barrel defining a barrel axis and having a muzzle towards the front end of the howitzer and a breech towards the back end of the howitzer; a cradle for holding the barrel at an azimuth and an elevation; a recoil accommodating mechanism such that the barrel can move along the barrel axis relative to the cradle; a bearing for varying the azimuth of the cannon; and a linkage for varying the elevation of the bearing.

Abstract: A gun comprising: a generally tubular barrel defining a barrel axis and having an external barrel surface about the perimeter of the tubular barrel a cradle having a cradle bore for accommodating a section of the barrel wherein the barrel is slidably mounted in the cradle bore such that the barrel can move relative to the cradle along the barrel axis across a range of barrel positions and wherein an interface defined by the slidable contact between external barrel surface and the cradle bore—i) prevents rotation of the barrel relative to the cradle about the barrel axis; and ii) is maintained at a single section of the cradle over the entire range of barrel positions.
