Subsea Systems - Quality in the harshest of environments

STS Defence designs and manufactures highly-specialised, bespoke subsea connectors, electrical umbilicals, cables and antennas designed for use in under-sea or harsh environments.

We specialise in adapting commercially available products for use in subsea and harsh environments, tailored to specific customer needs. This allows us to offer a very wide range of connectors at a very competitive cost and lead times when compared to traditionally manufactured subsea connectors.
