This is my kind of thread drift!
Agreed the first Lightnings had woeful range. Wasn't the joke at the time that the pilot had to declare a fuel emergency lining up for take off! This range issue was much improved with the later F.6 with those strange looking over-wing tanks and the larger belly "slipper" tank. The sad thing for me with the Lightning was it's woeful marketing for overseas sales (Kuwait and Saudi Arabia being the only other users) and woeful underdevelopment of it's weapon systems.
F.1 had two cannon and two Firestreak missiles (I.R that could not be used in cloudly conditions - what a feature in the UK environment!
)
F.2 had four cannon and the two Firestreaks
F.3 - No cannon! Two Firestreaks/Red Tops
F.6 - Two cannon in a pack under the fuselage plus two Red Tops (missiles could also not be used in cloudly conditions and was rear-aspect use only. It was more sensitive than Firestreak though being able to look onto heat generated by skin friction).
Imagine the Lightning with a decent radar, AIM-9L/M's and even the AIM-7F Sparrow. The Saudi F.53's could drop bombs and fire A/G unguided rockets at least, so of much greater use.
Lightining must go down as one of the greatest fighters ever built from a pure performance aspect and one of the most under-developed and marketed. Lighting would have been a much better fighter for NATO countries than the F-104 in my opinion, if it had been better optioned as far as A/G weapons goes. Lockheed had way better sales and marketing people than E.E/BAE and the F-104 offered much better A/G weapons versus pretty well nil for the Lightning (until developed for the Saudi's and Kuwaiti's).
From a range point of view, RAF F.6 Lightnings did deploy to Singapore for a perod - took something like 15 air refuelings. These Lightnings also visited Darwin on exercise over the four years of this deployment.
