Garuthmantha or Garuthmaan is another name for Garuda in Sanskrit. Both glide bombs are named after Garuda.

Re: Indian Cyber Warfare Discussion

We are now making 180 nm Military/Space hardened chip(and even the US used 90 nm military/space grade chips). We may also be moving to 90nm technology.
So in areas where we need to keep absolute security we need to move to better fab technology.

People here are mistaking the SR71's fuel leaks with other planes. That was by design as the plane expanded so much due to heating that it locked the leaking joints. Typically it had to be refueled immediately on launch. The leak was actually minimal. The plane actually expanded by several inches on...

A flying test bed is not just about the plane that carries the engine. tHe faulty engine can alys be shut down if it malfunctions.

Yes because Russia charged a stupendous amount and were themselves not sure about integration. The design for strengthening was over and above what was an existing aorframe without abrogating whatever agreement we had signed up for initially. Complex interplay !

This argument is going around in circles. Please stop it. Kaveri can only be integrated when we get a fully tested engine as per norms . So far we do not have it. Once it is achieved we can integrate it. Till then everything is just speculation.
