Abstract (en)

[origin: WO9641114A1] A projectile (50) is propelled from a location in air, through an air/water interface, and toward an underwater object (24). The projectile (50) includes a forward end (52) that forms a cavitation void (30) around the projectile (50) in water, avoiding water drag on the remainder of the projectile (50). The projectile (50) further includes a lateral stabilizer (90) that contacts the side of the cavitation void in the event that the projectile (50) yaws into a wall of the cavitation void (30) as it passes through water, producing a restoring force that prevents the projectile (50) from tumbling.
