Abstract: This disclosure relates to a light mortar for fin-stabilized projectiles comprising a mortar barrel defined by upper and lower tubes, means for pivotally mounting the upper and lower tubes relative to each other about an axis transverse to the axis of the mortar barrel, linkage means disposed between the upper and lower tubes for imparting a relative force therebetween to pivotally move the upper and lower tubes relative to each other about the pivotal mounting means between a coaxially aligned firing position and a position of misalignment of the tube axes, a pair of support columns between the upper and lower tubes with the pivotal mounting means being in spanning relationship between the support columns, the linkage means also being disposed between the support columns and including a toggle system having bell crank means for imparting the relative force to pivotally move the upper tube relative to the lower tube, and a half-shell supported by the support columns adjacent an upper end of the lower tube with means for locking a lower end of the upper tube to the latter-mentioned half-shell.
