I found this article where HAL Industry's are upgrading there Mig-27 attack jets to date the project isn't going well. This is an old designed based off a Mig-23 attack model and the aircraft itself is: heavy, average range, average payload, and has engine problems according to this article still not resolved, even after the upgrade. Like India's Mig-21bis, Mig-21/93 other models that should have been replaced a long time ago are still flying. A good portion of India's fleet are these older types which in the past may have served well but there time has come and pasted. India's Mig-29 fleet (about 60 aircraft) is also old as well as is there (2) Mirage 2000 squadrons. Remember India's AF is planing on having 230 MKI Flankers but do not have these numbers currently and still relive on these older types. Not that I want Pakistan to have modern fighters but if China decides on a final design model and picks up production in two years or so Pakistan may begin to come close to India's modern fighter levels in time. I still rate the MKI Flanker with there powerful Bar's radar a better fighter/attack platform but India's high end Flankers can't be everywhere?
