Hitachi and DeRegt took the challenge of developing a mine-hunting sonar system that had to be completely non-magnetic. DeRegt developed and successfully qualified a two-cable system using a unique Nitronic 50 armour package. The first systems have been successfully installed on Japanese Navy vessels and exceed operational requirements.

In cooperation with Thales, DeRegt developed tow cables for the CAPTAS 2 and CAPTAS 4 sonar systems, which are used by multiple navies worldwide. The cables were designed to meet the demanding operational requirements of and the harsh conditions faced by naval forces. DeRegt sonar systems and cables are used by the Royal Navy, the Italian Navy, the French Navy, the Norwegian Navy and many more!
