Its no co-incidence that both Concorde and TSR2 were fitted with the same basic engine, i.e. the Bristol Olympus albeit in 320 and 593 variants. They achieved supercruise by sheer brute force, the twin spool turbojet Olympus' they used produced between 20,000 and 31,000lbs of dry thrust repsectively. Compare that with the EJ200 turbo-fan fitted to Typhoon which produces a mere 13,000 lbs dry but is a much lighter and more compact unit.
