On the F3:
Lima Fit = 2x 2250L tanks - aka “big jugs”
Mike Fit = 2x 1500L tanks - aka “little jugs”
Romeo Fit = 1x 1500L tank on under-fuselage shoulder pylon (slightly offset either side) - aka “stupidy fit” because it looked stupid!
Ferry Fit = 2x 2250L tanks, 2x 1500L tanks - no AMRAAM or SkyFlash can be carried. Aka “ferry fit”
A Tornado F3, ZE155, flew unrefuelled in ferry fit non-stop across the Atlantic from Goose Bay to Warton on 24 Sep 1987. It was the first RAF fighter aircraft to do so without air-to-air refuelling. The flight took 4 hours 45 minutes.
