It most certainly is not enough, that's why the cooperation with Belgium will be intensified to provide air cover (QRA) with enough jets.
Also it won't do all tasks the F16 had, most notably the nuclear task, according to the defense minister , the Dutch JSF will no longer have a nuclear role like the F16 had before, also some other tasks, like Recce will be done with drones iso dedicated F16's.
As for the Belgians, it seems ever more likely that we will also join the JSF party, probably with an even more insignificant number of jets (23-28), certainly now that our Minister of Defence, P de Krem is a candidate for the position of NATO-Chief , the chance becomes ever more likely that our Air Forces interests will be coupled with the political ambitions of some ambitious politician and everybody knows that without the support of the US, nobody can become chef of NATO.
So a combined force of 60-ish jets seems not unlikely.
But honestly, what does all this matter it's not like we're going to do anything useful with those jets anyway.
What struck me as funny is how almost everyone these days is mainly emphasising on how important the F35 is as a jobs program, Politicians and almost all others involved with this program both on this side of the pond and in the US and Canada are almost all hammering solely on the economic importance of the F35.
Military reasons have taken a back-seat completely in this whole debate.
At least they're being honest about it.
The latest discussions however have put some serious question marks at the economic spin off numbers as initially promised.
With the volume of work already allocated to Japan and Israel, the Tier 1 level certainties the UK has and the addition of new partners (Korea and Singapore very likely) and the knowledge that the Dutch are the firts that have officially reduced their orders by more than half it becomes very unlikely that the promised work-share remains the same.
