Reference the F3 flying clean or with stores. With 2x winders and 2x skyflash and 2x Big Tanks, I can confirm that the jet would do well over 700kts at low level (I know, RtS and all that
). As I said, without tanks and with similar weapons 800kts+ is not difficult - the old HUD used to stop at 999 as well

750IAS at 50,000ft was the supposed maximum for the F3 from the release to service - that's about 1250kts TAS or 1,400mph depending on the OAT. You needed to throw fuel out of the back at 700kgs per minute to get there and so you wouldn't be doing it for long but it gave your missiles a hell of an extra reach (roughly 50-70% longer).
And before the "beadwindow" police get on their outrage high horse, the F3 retired this year from operational service and I don't see us breaking the half a dozen out of the museums just yet (the rest were broken up and robbed for useful spares for GR4s under "reduce to produce" at RAF Leeming
)
