01/31/2010. Built by English Electric as a B(I).Mk.8 in March 1956, this aircraft never served with the RAF, as is was transferred to the Controller (Aviation) Ministry of Supply and subsequently used in testing various equipment and weapons, including the Low Altitude Bombing System, Microcell Rocket firing trials, drop tanks carriage and release flight trials, torpedo separation trials, conducted in the UK as well as in Australia. In 1972 the aircraft underwent a conversion and was fitted with a B.Mk.2 canopy, the pictured longer nose, and various other systems.

It returned to service in 1975 and soldiered on for another eighteen years of testing, being withdrawn from use in September 1993. It was put up for disposal in 1994 and was purchased via auction by Classic Aviation Projects. Registered G-BVXC on January 9, 1995, it made its last flight on January 28, 1995, when it was delivered to Bruntingthorpe. Nicknamed "Treble Three" the aircraft is kept in taxiable condition and makes several taxi-runs a year. The registration was cancelled on January 9, 2003.
