Back in the mid 90s I applied for a job on the Tornado replacement's project team. They were working on a project called FOA (Future Offensive Aircraft), in the depths of some place or other which escapes me right now. Not long after I became ineligible for the job, the name changed to FOAS - Future Offensive Airborne System. The change came about because some forward thinking geezer realised that the Mighty Fin's replacement didn't necessarily have to be a manned aircraft.
It is due in service round about 2020, so you fast jet pukes are all probably safe until roughly 2035, after that be prepared to ask the nice customer if he would like fries with that!
