A gun mount is constructed of a plurality of alternately curved and flat isogrid plates arranged, annularly about and extending upward from a generally circular base, the plates being secured together to define a generally U-shaped shell-like structure having a pair of spaced apart upwardly extending trunnion support members, the grid structure of the flat plates consisting of an uniform unflanged isogrid structure which terminates at a pocketed transition section on three sides and a stiffened edge along the top, and the grid structure of the curved sections consisting of radial grid members which are intersected by curved diagonal grid members describing exponential spirals.
