The Bristol Britannia Civil and Military

xm496 nose

The Bristol Britannia was the world’s first long haul prop-jet airliner. It was developed as part of the drive to re-build Britain’s civil aviation industry after the Second World War when the focus had been on fighter and bomber production. In June, 1957 one made a record breaking non-stop flight from London to Vancouver on the western coast of North America in less than fifteen hours. This was only one of several record breaking achievements. On 19th December 1957 it was the first airliner to fly non-stop, scheduled, passenger services between London and New York, the Holy Grail of Post War air travel. (1) US airliners already flew the route but with a scheduled stop. Nearly a year later the Comet 4 joined the route. (2)

The Bristol Proteus engines which powered the Britannia were the first in the world to have “control-by-wire” using the Ultra Throttle system. This was later used on Concorde. Sadly, the Proteus is mostly remembered for icing problems, which were overcome.

As a long range military transport aircraft it could lift eighteen and a half tons over 4,000+ miles, carrying freight, or up to 53 stretchers with medical personnel and life support equipment or 115 passengers, in any combination. It was the Royal Air Force’s first strategic airlifter and a crucial component in the reshaping of Britain’s armed forces to meet the new threats of the Cold War. Its tasks included the rapid deployment, worldwide, of the then newly formed Army Strategic Reserve, and moving the V- Bomber Force, including the Vulcan, to its dispersal airfields.

Flown by 99 and 511 Squadrons, first at RAF Lyneham and later RAF Brize Norton, when the Britannia was withdrawn from service in 1975 as part of defence cuts, the Squadrons were stood down. In 2000, 99 Squadron was reformed to fly the Boeing C-17 Globemaster. The aircraft is different, the role is the same.
