Ammunition preferaqbly for use in high-angle fire to be fired from a cannon suitable for flat trajectory ammunition and with direct participation of the cannon barrel, the ammunition being made of one piece as an ammunition unit having the same outer dimensions as a comparable ammunition unit which is intended to be fired from the same cannon exclusively with an essentially flat trajectory, the ammunition unit including a propellant charge and a payload projectile having a rear portion occupying a region corresponding to that occupied by a portion of the propellant charge of the comparable unit.

An ammunition unit for use in an automatic tubular weapon having a barrel that can be selectively oriented to effect flat trajectory or high-angle trajectory fire, said ammunition unit being constructed for one of flat trajectory fire and high-angle trajectory fire, and wherein: said ammunition unit is a one-piece unit and comprises a propellant charge means, including at least a cylindrical member having a bottom face at one end, for providing a propellant charge, a ballistic payload projectile secured in said cylindrical member of said propellant charge means at the end thereof remote from said bottom face and having a bottom member which faces said propellant charge means and delimits the rear end of said projectile, and a payload disposed within said projectile; said ammunition unit has a given length, outer diameter and external shape, with the portion of said projectile which projects out of said cylindrical member of said propellant charge means having substantially the same outer diameter as said cylindrical member, and with said projectile of said ammunition unit having a main cylindrical portion of constant diameter and a short ogival front end portion; said propellant charge extends between said bottom face and said bottom member, with the quantity of said propellant charge being a function of the type of trajectory over which the ammunition is to be fired, and with the distance between said bottom member and said bottom face of said ammunition unit being greater for flat trajectory fire than for high-angle trajectory fire, and with said ammunition unit containing a greater quantity of propellant charge for flat trajectory fire than for high-angle trajectory fire; said projectile of said ammunition unit is shorter for flat trajectory fire than for high-angle trajectory fire; and said ammunition unit has a smaller quantity of payload for flat trajectory fire than for high angle trajectory fire.
