Why j8f has pl12 but ja37d and ja39a all not have rb99?

In yesterday’s live broadcast, I saw that The Swedish Air Force needs to open a new plane if it wants to take the initiative.However,the previous Swedish aircraft also have the ability to fight active radar missiles.Why can’t we fire active radar missiles like China’s J8F?


I made a post asking them to add the Aim-120 to the JA37D Viggen. At least that one, the gripen A well… were getting the C I mean, but since most of nations (except Germany, JP) are getting at least 2+ aircraft with FOX3.
(G.Britain getting 3 planes with Fox3 launchers is ass, there are nations with only 1. Gaijin should do something tbh)
