Can it replicate this in Leh and Arunachal/Sikkim, with full loads ? If so, a few squadrons with small airstrips in the mountains may seem a very good idea.
The Gripen-NG supposedly passed the high-altitude tests held at Leh. I don’t think any aircraft in the competition could take off wih a full load in the Himalayas; the demands on the engine are too high even with a full-size runway. Which is why four of the aircraft failed initial trials at Leh.
