Apparently it was changed halfway to the SD but the AE makes the bulk of the order.
The article from scramble mentions the AE were only produced in Ukraine by Artem, and that Russia was only a token user of the Artem imported R-77 until the point it started making the R-77-1 (export desig RVV-SD). So how can the Indian order have AE versions, does Russian make them?
It was a surprise to me that until now Russia itself wasn't a major R-77 user.
