Armor piercing projectile

An armor piercing incendiary projectile comprising:

• body means;
• penetrator means contained within said body means, said penetrator means having a maximum length-to-diameter ratio of 5:1, said penetrator means having a tip and a base, the shape of said penetrator means being an envelope from tip to base substantially defined by an exponential curve of revolution about its longitudinal axis, the exponent of said curve being greater than one, said shape providing weight distribution that increases the mass on the outer periphery of the penetrator to maximize the polar moment of inertia to provide favorable stability characteristics;
• support means interconnecting said body means and said penetrator means, said support means being made from a ductile metal;
• wind cover means surrounding said penetrator means and connected to said body means to provide a low drag profile;
• and
• band means circumferentially mounted over said body means to spin stabilize the projectile.
