Millennium Gun

The Millennium Gun, a naval deck weapon system, delivers inner-layer defense against sea-skimming antiship missiles, antiradiation missiles, and aircraft. It is also effective against fast-attack surface craft and near-shore targets during operations in littoral and riverine waters. Creating a "wall of lead," the Millennium Gun fires 35-mm ammunition, including the advanced Ahead round, at 1,000 rounds per minute. Each Ahead round disperses 152 metal subprojectiles. Forming a cone-shaped pattern, the subprojectiles destroy a target's control surfaces, seeker and other vital equipment components as a target moves through the wall of lead. The gun's muzzle brake programs each Ahead round as it exits the barrel, setting distance and subprojectile dispersal pattern.
