Abstract
The present invention relates to a long-range artillery shell (1) that is fin-stabilised in its trajectory and which is designed to be fired in a rifled gun barrel and thus has a slipping driving band (8) as main contact surface with the inside of the barrel, and has a so-called base-bleed unit (3) with a number of stabilization fins (9-14) that are deployable after the shell has left the barrel. A special feature of the shell (1) as claimed in the present invention is that the fins (9-14), when activated, are radially displaceable to project outside the external periphery of the shell through slots or through-holes (28) in the wall of the shell, but are initially radially retracted inside the propellant motor section or propellant chamber (4) of the base-bleed unit (3) between dedicated protective walls (16-17) that isolate the fins from the surrounding propelling charges (25) of the propellant motor and also divide the inside of the propellant motor (4) into sectors (18-23) that are separated from each other.
