not true, jojo
1) there's no such missile as R-77-1
2) Russia has been massively exporting a missile called RVV-AE (factory name "Izdelie 170E" or "product 170E") to China, India, Algiers, Venezuela, Vietnam, Indonesia, Syria, Malaysia since mid '90s and up to current date
3) Local version of RVV-AE (called R-77, factory name "Izdelie 170") entered service in mid '90s as well, but indeed it wasn't massively fielded in our air force, since in reality it didn't suit MoD's requirements
4) there is a new missile which still doesn't have name, but it has factory index "Izdelie 170-1" (or "product 170-1") which is a deeply reworked variant of R-77, but in this case it does suit MoD's requirements. it's being massively produced since ~2012, and we're seeing it in our air force.
