Gun shield

The composite gun shield of this frigate has been modified to absorb the “green” water loads, that are typical to the northern waters. This modification is also used to improve the Radar Cross Section (RCS) performance. The sonar/radar transparency property of certain composite materials is a perfect solution for this gun shield.

Sonar/Radar Transparency

Composites are very well known for their transparency to radar and low damping properties.


The specific weight of composites varies between 1.5 and 2.0 compared to 2.7 to 7.8 for aluminium and steel.
