Currently, the missile deployment of Su-27SM is not uniform and is very difficult to research.
before look su-27sm, take su-27 and su-30
The difference is that both can research missile parts from rank 1.
Furthermore, the fact that there are two missiles in rank 4 on Su-27sm makes it really difficult to reserch
I think it would be reasonable to place the R-73 in rank 1, the R27T/ET in rank 2, the R27R/ER in rank 3, and the R-77 in rank 4
I hope Gaijin will improve this point…
