Rheinmetall Air Defence

Sea-Based Air and Surface Defence Systems

The complex requirements imposed on short and very short-range air and surface defence have become much more complex in recent years. Both quantitatively and qualitatively, the air and surface threats posed to naval ships continues to mutate and multiply.

Increasingly, the emphasis is on highly manoeuvrable anti-ship missiles, unmanned air vehicles and surface swarm attacks that are smaller, faster and more agile than ever; only the most sophisticated air and surface defence systems can provide protection against these threats.

Advanced close-in weapon systems

Rheinmetall Defence's air defence division is one of the world's foremost makers of advanced close-in weapon systems. The company leads the global market in automatic cannon-based air defence, and is the only system supplier able to offer fire control technology, automatic cannon and Ahead airburst ammunition, all from a single source.

Fully automated and extremely effective, the high-performance systems are ideal for protecting naval crews, ships and further high-value assets from modern symmetric and asymmetric threats. Thanks to the company's Ahead technology, the systems are able to take out even the smallest targets.
