The Hyper-Velocity Powder Gun fires a Hyper Velocity Projectile (HVP) from the 5-inch gun (MK 45) mounted on Navy ships or Army Paladins.[2] The HVP is fired at Mach 3 and can travel a distance of approximately 30 nautical miles. This system can act as either a surface-to-surface weapon or a surface-to-air defensive weapon.[3] The HVP fires at half the speed of a rail gun but still fires twice as fast as a traditional powder gun projectile.

The Hyper-Velocity Powder Gun can easily be installed on Navy ships with existing 5-inch guns,[4] and most Navy Cruisers are equipped with two mounted 5-inch guns and Navy Destroyers are equipped with one mounted 5-inch gun. Another positive aspect of this weapon is its’ cost efficiency, each round costs only $25,000-$50,000 compared to millions for traditional missile defense systems.[5]

The Hyper-Velocity Powder Gun is still being tested and is waiting be added to the United States Ballistic Missile Defense arsenal.
