It's not only a matter of having a runway available. The F-35 is very data-centric and is very dependable on IT-systems which need connectivity also on remote sites. This can be easily solved by using modern 4G/5G networks (either dedicated MoD ones or public ones) with the "right" encryption running over it cleared for military use, but it is a constraint which needs to be taken into consideration. In the Gripen/Viggen days, you probably only needed a few trucks with equipment/fuel and conscripts. Now you need additional "datacenters in a box" to make this work.
