Not quite one size fits all. In fact not al all really. The F-35 will come in three versions. The A is purely conventional to replace the F-16 fleets and has more fuel where the fan is in the B model. The B has the operating site flexibility of STOVL to replace all Harrier variants, while the C has a wing extension, stonger gear and a hook to replace the F-18A/B in navy ops. Commonality of over 70% has led to a real control of costs compared to needing three totally different aircraft.
