WHAT WE DO
Formed in June 1952, 591 Signals Unit has been continuously supporting Operations with technical security and expertise ever since. Today, it is the RAF's Defensive Cyber Air Combat Service Support Unit. Transferred under the organisation of 90SU in January 2016, it forms the Defensive Cyber Operations (DCO) arm of the Air CyISOC.
It supports the cyber resilience of UK air power by delivering intelligence-led defensive cyber operations capability to provide Information Assurance, help identify and mitigate Air's cyber vulnerabilities, and by maintaining Force Elements at Readiness (FE@R) to respond to cyber incidents worldwide.
