Naval Air Defence

All the benefits of our ground-based air defence systems, specially adapted for layered naval air defence tasks.

Oerlikon Millennium Gun®

In an anti-surface role, the Millennium Gun is a fast and powerful effector. The gun system is designed to engage multiple high-speed asymmetric surface targets (swarming attacks). It exceeds United States Navy keep-out-range requirements for countering a multi-axis threat from multiple fast-intruder attack craft.

In an anti-air role, the Millennium Gun can engage a large spectrum of air threats, ranging from low-radar cross section anti-ship missiles to fast-attack aircraft and helicopters.

Additionally, the Millennium Gun can easily defeat challenging low, slow and small air threats posed by unmanned aerial vehicles (UAV).

The Millennium Gun, with its programmable Oerlikon Ahead ammunition, has also been deployed to provide counter rocket, artillery and mortar (C-RAM) defence for land-based applications.
