A sabot adapted to be attached to a subcalibre projectile comprises a generally cylindrical tubular member having a plurality of elongated axially-directed slots passing completely through the member in a radial direction with the slots extending from one end of the cylindrical member toward, but terminating short of, the other end of the member to define a plurality of spaced, elongated axially directed segments which are integral with an unslotted portion of the member adjacent its other end. The unslotted portion acts as an obturator, and the dimensions of the unslotted portion and of the segments are so selected that centrifugal and/or airflow forces acting on the segments after the projectile has been fired operate to break the unslotted portion of the sabot into pieces to separate the sabot from the projectile.

A unitary device adapted to be attached to a subcalibre projectile for performing the functions of centering the projectile in a gun barrel and obturating said barrel against expulsion gases developed in said barrel at the time of firing to effect propulsion of said projectile from said barrel, and so constructed that said unitary device is fractured into plural pieces by centrifugal and/or airflow forces imposed on said unitary device when said projectile has been fired, said unitary device comprising an elongated generally cylindrical tubular portion adapted to be disposed about said projectile in coaxial relation thereto, said cylindrical portion having a plurality of elongated generally axially directed slots therein disposed in spaced relation to one another, each of said slots extending completely through said cylindrical portion in a radial direction and each of said slots opening into the forwardmost end of said unitary device and extending in an axial direction rearwardly from said forwardmost end to a position closely adjacent, but terminating short of, the rearwardmost end of said unitary device, whereby said slots define therebetween a plurality of spaced, elongated, axially directed segments which have spaced, free ends at said forwardmost end of said unitary device and which segments are integrally joined to one another only at a comparatively thin unslotted portion of said device adjacent its said rearwardmost end, said unslotted portion of said device acting to hold said spaced segments in position relative to one another along said barrel before said projectile is fired, said unslotted portion including an integral, generally axially directed, threaded outer peripheral surface coaxial with and spaced from said projectile, a driving band disposed at the rearwardmost end of said device about said unslotted portion of said device and having an inner threaded surface in thread engagement with said threaded outer peripheral surface of said unslotted portion, said unslotted portion defiNing, as an integral part thereof, a surface located at the rearwardmost end of said device extending transverse to the axis of said projectile and operative to obturate said barrel when said projectile and said unitary device are inserted into said barrel for firing, the thickness of said unslotted portion in an axial direction being a small fraction of the axial length of said spaced segments whereby centrifugal and/or airflow forces acting on said elongated, spaced segments after said projectile has been fired are operative to effect a pivotal motion of the free ends of said segments about the rearwardmost end of said unitary device to break said unslotted portion of said unitary device into pieces and thereby effect separation of said device from said projectile.
