Typhoon93, final numbers for UK F-35B not fully decided. Original thoughts were about 130/113 in about 5 front line squadrons, plus training, spare and reserve aircraft.
14 ordered. Next term goal is 48 aircraft, the stated minimum to have 2 squadrons, a training element, test, maintenence, spares etc.
I think the final UK order will be above 48, but less than 120.
Load out between B's and helos on new carriers totally depends on the mission. For an air defense or just carrier strike mission you will have B heavy air wing (Kosovo). An Assault carrier mission, evacuation, ASW, etc helo heavy. Falklands II a mix. The scenario of both carriers with a full max load of B's is unlikely.
