Only the Brits could design an aircraft that wouldn't go supersonic with afterburners, it even slowed down if you plugged the burners in!! The last mark (FAW9??) had burners to increase high altitude performance. However, if you put the burners in at low level the nozzles opened but the fuel pumps couldn't deliver the required fuel so you lost thrust.
I think the last one flying was at Boscombe and painted red and white.
