NASAMS II should work through Link 16. Technically the whole FDF is networked in such way and shares the same situational picture (e.g. Navy has L16/22 on all ships - Swedes are lagging in this regard, they ordered L22 only in 2018 almost a decade later than Finns**), there's no barriers like between services in the US.
This system extension looks to be quite modest, given there's nothing close to Patriot level money reserved for it. But the rollout will happen 2025-> right at the same time with HX fighter jets.
But they don't necessarily come from the same country.
Amraam-ER could be the favorite since they don't need to introduce another system alongside Nasams like some of the other options.
Barak 8 already lost to ESSM in the corvette bid.

Small excerpt about the state of connectivity.
This enabling technology is called Multi Data Link Processor (M-DLP): in these simple four words, it represents the widest response in the tactical field when it comes to sharing and interpreting different type of links, whilst integrating different languages and protocols into a common format, with an ability and implementation that guarantee the highest level of interoperability among warships, aircraft, ground assets and command posts.
However, one can ask, how is it possible to provide full data forwarding capabilities with tools to build a real-time shared common operational picture?
The M-DLP is without doubt the most advanced product available, as it integrates and interprets all of the different formats, languages and "protocols" of the Data Link universe (Link 11 a / b, Link 16, Link 22, JREAP B&C, IFF M5 and VMF), therein achieving a true and full interaction and interoperability. This is in part due to Leonardo and Italy’s involvement and participation in the Data Link Working Group, which develops the standardisation of tactical Data Links within NATO’s framework. One of the leading Nations in Data Link and M-DLP implementation is Finland, and Leonardo is very proud of the fact that the solution it has adopted was designed and manufactured by Leonardo.
Leonardo is also a leading provider of Data Links, particularly in the development of Link 22 within the NATO program NILE (NATO Improved Link Eleven). At the moment about 200 Leonardo M-DLPs operate globally within various Defence Forces.
