[Dons ex-TSW CLA cap for a moment]
The majority of sites that state they only stock F44 are usually only partially right.
F44 is rarely received onto land-based facilities as such, rather it is more often than not supplied as F35 and then blended with the required FP raising and FSII chemicals on site to produce F44. This is purely an economic and ease of supply issue, F35 being far more widely available than any other type of turbine fuel.
As an aside to this I'd be fairly sure that Sig would have stocks of F35 alongside its stocks of of F44 as it is common to allow F35 to 'settle' before running it through a blending rig to ensure built up static can discharge.
All UK military a/c can operate on F35 although F34 is preferred and if this is what is required a blending rig and a a few 136k TFCs is all that would need to be set up. An easy job even in these cash and staff strapped times. We managed to operate Basrah AB and supply all UK F34 requirements in Iraq from such a setup.
