Re: Indian Military Helicopters

ToT has typically jacked up the price by atleast two times. The Kamov deal is no different.

Russian Kamov helicopters' 'Make in India' price 2.5 times more that original cost

Dileep sahaab,

I knew that Python-5 could go onto LCA only if either the aircraft or the missile changed. There is no way the aircraft will change now.

I was hoping that the modifications done for integration into JSF might make it feasible. Well time will tell.

Viv, your inlets have to be of variable geometry to reach 2M. But, you need sufficient oomph too.

The Mig-21 is basically cylinder around an engine. It's shape and TWR will allow more bulges at the center. This isn't the case with LCA, Gripen, Jf-17 etc.

What should the size of such a fighter be? If you want decent range on internal fuel only then making a fighter powered by a single FGFA engine makes sense.
