A presentation by the Indian Air Force to the government has revealed some deficiencies of the Tejas fighter against the F-16 and Gripen.
The service is trying to explain its case for buying a single-engine fighter in the open market instead of increasing its order for Tejas.
One of the complaints against Tejas is that the jet can stay airborne for 59 minutes only, compare to more than 2 hours for the foreign fighters.
The payload of the indigenous jet is also less than halve of what the American and Swedish fighter can carry.
