Sweden sold a lot of kit to NATO nations of one sort or another.
Some random thoughts in my head:
More Penguin ASMs on FACs and frigates, could see W. Germany going for these on their FACs instead of Exocet.
RBS-15 ASMs in the 1980s.
Continued development of Sidewinder/Sparrow/Falcon by Sweden with NATO partners, probably inclusion in ASRAAM, more Sky Flash involvement, perhaps getting Active Sky Flash off the ground too.
Swedish licence-production of US or UK radars and fire-control kit, would make Draken and Viggen even better.
Less engine woes (less resale clauses to worry about).
Draken would give F-104 a real hard time in the 1960s I think.
Viggen would outclass Jaguar and be a direct Mirage F1/YF-16/YF-17 competitor, it might even clinch the Eurogroup fighter deal in 1974.
Swedish subs might challenge the Type 209 series for sales.
Swedish FACs Vs La Combatte and Lurssen types.
