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.
