DH Vennet Mk II: Ultrasonic World Beater.

The original “Vennet” was contrived by the engineers of No.12 Hangar at Abbotsinch for the 1961 Navy Day. The conversion involved an old Sea Venom with its tail booms and tip tanks removed and with a pair of the Fairey Gannet‘s rudders fixed to the boom attachment points. A fancy “supersonic” pitot nose intake and two pipe-derived fake missiles were added to match. It was a runner too. On that Navy Day, the “Vennet” reached circa 90 knots on the runway, its tired Ghost engine generating lots of noise and fun.
This photo was taken next year, when an improved “Vennet” was created by the technicians of No.10 Hangar to take part at the 1962 Navy Day. Their “Vennet Mk II” added a convincing pair wing-tip ramjets, just for kicks.

Thanks to John Horton for the tip.
