Our Heritage

With its rich and varied history, 21 Signal Regiment can trace its roots back to the Second World War as an Air Formation Signals unit; its technological prestige earning itself the Bristol Beaufighter as its regimental emblem – the most advanced fighter-bomber of the war.

After a lengthy history stationed in West Germany supporting the British Army of the Rhine, the Regiment  moved to the UK in the mid 1990s. Here it became Defence’s only Air Formation Signals unit, and supported the Joint Helicopter Command throughout the Iraq and Balkans campaigns.

In recent years STRIKE communicators have operationally deployed to Afghanistan, Iraq, Estonia and South Sudan, and undertaken exercises in Germany, Canada, the United States and Oman. They have also supported UK operations, notably during the COVID-19 pandemic. 


21 Signal Regiment is located in Colerne, Wiltshire, just outside of the historic City of Bath. The Regiment has a strong affiliation with Bath, having been awarded the Freedom of the City following operations in Afghanistan in 2011
