Our Canberra T.4 WH840
Canberra T.4 WH840 was one of the RAF’s dedicated twin-seat training variants of the legendary English Electric Canberra — Britain’s first jet-powered bomber and one of its most successful post-war aircraft. The T.4 version was developed to train pilots and navigators transitioning to the Canberra B.2 and later marks.
Built in the early 1950s by English Electric at their Preston facility, WH840 entered service as part of the RAF’s operational conversion units (OCUs) and flying training schools. As a T.4, it was fitted with a fully duplicated cockpit side-by-side under a long glazed canopy — the most visually distinctive feature of the type — and lacked the bomb bay and offensive capabilities of bomber variants.
WH840 served for many years as a pilot trainer, most likely with units such as No. 231 Operational Conversion Unit (OCU) or No. 7 Flying Training School (FTS). The T.4’s side-by-side seating arrangement made it ideal for advanced jet training and Canberra type conversion, preparing crews for a wide range of reconnaissance and bombing roles.
In its later years, WH840 was withdrawn from flying service and, like many Canberras, avoided scrapping due to its iconic status. The airframe was transferred to the Norfolk and Suffolk Aviation Museum at Flixton, Suffolk, where it is preserved today. It stands as one of the better-preserved examples of a T.4 and is notable for its canopy design, paintwork, and completeness.
