Every sonar engineer knows that signal clarity begins with the cable. But in naval defense, not all sonar systems are created equal. And neither are their cables.
At DeRegt, we’ve spent decades helping navies and defense engineers turn hydrodynamic challenges into predictable performance. In this article, we explore two main sonar architectures: Towed Array Sonar and Variable Depth Sonar. And how depth, buoyancy, and cable mechanics reshape what’s possible underwater. Because sometimes, being able to detect an enemy is just a matter of a few grams per meter, or the right cable design.
