Armor piercing ammunition having interlocking means
First Claim
1. An ammunition round adapted to be propelled into ballistic flight when discharged from an artillery gun bore comprising:
- a tubular outer sabot having on the inner tubular wall inwardly protruding helical threads which are both right-handed threads and left-handed threads;
an elongated projectile removably interlocked into said sabot during said discharge and adapted to be separated therefrom during said flight, the projectile having on its exterior wall outwardly protruding helical threads which are both right-handed threads and left-handed threads, which threads are removably intermeshed with the said respective right and left threads on the sabot.

Abstract
An ammunition round for an artillery gun comprises, as an armor piercing nd, an outer tubular disposable sabot and an inner projectile which are joined by interlocking means to join them until exiting from the gun muzzle and separates them in ballistic flight. The interlocking means comprises left-handed threads and right-handed threads; both directions of threads being on both the inner wall of the sabot and the outer wall of the projectile. In one embodiment the two directions of threads are on axially tandem sections and in another embodiment they are on the same section, to form a herringbone pattern with raised diamond-shaped protrusions.
