The United Kingdom has retired the Boeing E-3D Sentry AEW1 after 30 years of operational service.
A decommissioning ceremony was held at the type's main operating base at Royal Air Force (RAF) Waddington in Lincolnshire on 28 September.
Though a small fleet,
the Sentries were deployed in support of every UK air operation from the first Gulf War
through to missions against the Islamic State.
With just seven airframes to begin with,
the Sentry capability had been whittled down in recent years
as planned capability upgrades were shelved as cost saving measures.
By the time of the retirement ceremony, just three aircraft remained in a flyable condition.
The type's last operational mission was flown by 8 Squadron on 5 August 2021.
