Super Mirage F1 has no BVR capability according to this post, the SAAF Gripens have no form of BVR irl.
I personally think the SAAF Gripen should get the R-Darter which the SAAF had but didn’t use on the Gripen but the Gripen can 100% use it. As for the Mirage, this post seems to suggest they can only carry R-73 or Magic 2.
Not really sure what else to add to get this passed on, if a moderator wants to make suggestions as to what else I can research I’d be happy to look for it and add it.
This would make for a great premium or event jet for Great Britain.
It would go to the South African sub tree which happens to be in the British tree.
There is a very similar example to the Super Mirage which is the Super Hind both being South African modifications of foreign vehicles. And guess where the Super Hind is.
