It is not classified and in the new “Heavy Cavarly” we introduced the AGM-154 JSOW so I belive that it is only fair to give the CF-188 the weapons that they had. It is listed on the actual wikipedia that the CF-188 had AGM-154 JSOW and aim 120 so i suggest we add a new variant of the CF-188 like the CF-188B to great britan that introduces the AGM-154 and the aim 120.
For AIM-120s depends on what variants. As you have the earlier IMP upgrade with earlier 120s and the later HEP II with 120D-3s and AIM-9X. I’m, however, not sure when Canada got AGM-154, so not sure the earliest upgrade to get it.
I believe i have found your answer. The newer weapons are found on the CF-188B variant. so it shouldnt be hard to make perhaps a premium folder for the CF-188’s and add the CF-188B in it.
