Abstract: A sabot for launching a sub-caliber projectile (7) comprising a rearwardly positioned projectile pusher member (1) and a forward support structure (2), the support structure comprises frangible material which is collapsible by virtue of acceleration forces experienced during acceleration of the sabot. The support structure is preferably made of foamed plastics material and has a cover positionable to retain the projectile in the support structure. Such a sabot is particularly suitable for launching small projectiles during high velocity impact investigation. The invention also provides a method of launching a projectile using the sabot.
