Sercel has been a provider of custom engineered equipment for the underwater Security & Defense markets for a long time. Our expertise ranges from a wide and advanced knowledge base in underwater acoustics to industry certified industrial processes. The combination of which enables us to support your most demanding and unique naval projects. 


  • Acoustic communication:
  • Renowned for our advanced acoustic technologies, Sercel provides state-of-the-art and custom-engineered solutions for long-range and inconspicuous underwater communications.

  • Acoustic positioning:
  • Sercel designs and manufactures acoustic transponders for the accurate positioning of all types of underwater systems. Our acoustic positioning solutions are scalable for use on small to large projects.

  • Acoustic measurements:
  • Sercel offers acoustic measurement techniques capable of detecting and precisely locating emitted sounds as well as collecting and characterizing anthropic noise either through pressure or particle motion analysis.

  • Acoustic classification:
  • Sercel provides acoustic classification tools based on A.I. (Artificial Intelligence) techniques.

  • Acoustic transducers:
  • Sercel has an in-depth knowledge of the design and manufacturing of custom transducers. Our finite-element simulations and specialized acoustic tank allow us to develop high-end transducers with high quality standards.

  • Towed antennas
  • With over 60 years of experience and excellence, Sercel has established itself as a major designer and supplier of a broad range of marine products including ultra-light cables and advanced streamers through to sophisticated connector solutions. Based on this solid know-how, Sercel was able to extend its expertise to the defense and security markets and in particular address the requirements for towed antennas.


In addition to the wide spectrum of acoustic expertize highlighted above, Sercel is an industrial manufacturer with a world-wide reputation. Since 1956, Sercel has designed, manufactured and supported a full range of high-tech electronic equipment adapted to the harshest environments and conditions : we have specified equipment from -50°C to +260°C, from a few g up to 60 tons traction; and up to 2,600 bar.

Compliant with the highest ISO standard certifications, Sercel is ready to transform the most advanced and ambitious engineering design projects into customized and reliable real-world solutions.
