Re: Kaveri & Aero-Engine: News & Discussion
Give the Kaveri program at least half $3.5B and see what happens. Kaveri is so important not only for aircrafts but Ships for Indian Navy. All of the modern ships for Navy currently have GE powerplant - destroyers, frigates, aircraft carriers. A good Kaveri program can lead to ship engines which ar...

Re: Kaveri & Aero-Engine: News & Discussion
The nature of air war is changing. Fanne ji, I'm in 100% agreement. Kinetic performance like speed and maneuveability though vital, is not everything in today's war. Speed of fighter design can't catchup with speed of missile or radar development, or speed of EW development. Beauty is it doesn't ha...

Re: Kaveri & Aero-Engine: News & Discussion
Even if Kaveri weight is brought to say under 1100 kg with a 81KN wet thrust, with the flat rating, kaveri is nothing to be scoffed at. What we need is integration, even if it finally leads us only to a less powerful export variant of Tejas. A slightly heavier, similar thrust Tejas doesn't sound so ...
