Naval air defence

Oerlikon Millennium Gun®, Oerlikon Searanger® and Oerlikon Seaguard®

Rheinmetall's naval air defence systems integrate all the benefits of our ground-based air defence systems. Oerlikon Millennium Gun, Oerlikon Searanger and Oerlikon Seaguard are 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.

Oerlikon Seaguard® Biax
The Oerlikon Seaguard Biax is a versatile and highly effective naval tracking system. It is a 2-axis multi-purpose tracker suitable for all weather conditions equipped with the latest radar technology to counter the diverse range of symmetric and asymmetric threats that exist today including highly-agile anti-ship missiles.
