Abstract

L'invention concerne une structure porteuse (1) comportant une base (3), un cadre oscillant (4) ainsi qu'une structure supérieure (2) destinée à être équipée d'un système d'arme et/ou d'observation. La structure supérieure peut à la fois effectuer une rotation azimutale et pivoter par rapport à l'horizontale (élévation). La structure supérieure est montée de telle manière que le mouvement par rapport à l'horizontale suit une trajectoire en forme d'arc de cercle. La structure porteuse peut être utilisée comme structure fixe ou mobile. On obtient ainsi une hauteur totale réduite et un centre de gravité plus bas. Il est en particulier possible de réaliser une plate-forme d'arme pour des applications fixes ou mobiles.
