Instead of the F 16 production line....just transfer the GE 414 production line to India...that would be a much better option.
You mean screw driver tech ? G.E already has screw drive tech production of engines in partnership with HAL.
Similarly they have a factory in Pune that on paper does production. In realty, they do assembly of component.
Their composite blades however are made in the US, Lower gen single crystal blades are made in UK.
So don't hold your breath just yet.
