This must be after effect of that General Electrics deal for starting joint production of F414 engines here, else without sourcing engines of all IAF would think infinite times before going orders way
let's see if we also bring F404 line here or better upgrade all Mk1A with F414 in future (yeah i know dimensions and limitations and what not but still considering possibility)
That deal was going to happen anyway..been pending since a decade.
It's simply the effect of delay in mk2 timeline which is clearly visible now.
The current order may be completed early in that case IAF will have to order more.
At the same time they have nothing new coming in for next 5 years and 5-6 Squadrons will be retiring .
Earlier there were plans to simply use the F414 engine timeline was 2014 then 2018-19 around but after study it was dropped and instead a more refined mk2 version was considered to be paired up with F414.
More thrust means more fuel requirement.. and it is already shortlegged. Let's see.
In short we already have studied and worked out the solution. It's just it takes time and we are a bit slow.
