What We Do
SEA Logoartboard 1 Copy 42 Our History Delivering advanced systems to industry since 1961. Work With Us

For over 60 years now, we’ve been actively protecting customers and their assets. 

From the day we were founded in 1961, we’ve been delivering and supporting advanced solutions that maximise our clients’ defence and transport management capabilities. 

Today, from offices in Barnstaple, Beckington, Bristol and Canada, we provide engineering and software design services to Government agencies, industrial prime contractors, and academia. We’re renowned for our innovation, flexibility and out-of-the-box thinking. For solving knotty, complex challenges.  

In 2007, SEA was acquired by Cohort plc.

Cohort plc is the parent company of six innovative, agile, and responsive businesses providing a wide range of services and products for British, Portuguese, German and international customers in defence and related markets. Cohort aims to add real value through the experience and contacts of its senior team while providing a light-touch but effective governance framework. Its objective is to deliver value to shareholders through its six operating subsidiaries: Chess, EID, ELAC SONAR, MASS, MCL and SEA.

Cohort was founded on the principle that SME-size businesses can prosper by being part of a larger group, where they can benefit from financial oversight, management support and the exchange of information and practices. Cohort aims to achieve this while preserving the high growth potential of innovative independent businesses.
