But what motive does India have in this race??
It cannot compete with the others for passenger travel..
Is it just a tech statement??

Westpoint please ensure you research more before posting.
Also i recomend you to shed all patriotism and prejudice, try being more prudent while posting

I have heard of this program before, but it is good never the less.
The more compitition the US has the better, because that will force us to get it before everyone else.
As for the whole US vs India (or anyone else for that matter) - it's getting old. Does India have a very good modern airforce? Hell yes! Can they even hope to be realistically compared to the USAF at this point of time? Hell no!

Your posts are always about hyping some Indian aircraft - in this case a "hyperplane" for God's sake. If you also shed your 'patriotism' and prejudice, you'll have little to post about except pictures and models
The same kinds of things a lot of us drew and built when we were back in elementary school.
Now before you go and flame anyone else, it's way past your bedtime.

Stealth Spy hope your happy that they made me change my avatar, I guess little children like you can't handle cartoons wearing a flag
But don't worry, I've got something I'm working on right now that will be better than the last one.

cant argue with u there. but usa is not an enemy of india and vice-versa.there is no need for competition,. even if there were any it would be impossible for india to.

HYDERABAD: The Defence Research and Development Laboratory (DRDL) is poised to test-fly the first version of the hypersonic cruise vehicle in 2007.
It has asked the Andhra Pradesh Government to provide 2,000 acres of land on the city outskirts to set up infrastructure for the hypersonic flight programme.
"Work has been on for the past three years and we intend to test-fly the world's most integrated hypersonic system three years from now," DRDL Director Prahlada told presspersons here on Tuesday, on the eve of National Technology Day.
Hypersonic flights move at sustained speeds above Mach 6 — 6,000 km an hour or 5-12 times the speed of sound — and offer potential applications in military, space and civil use.
Dr. Prahlada said Russia and France evinced a keen interest to work on the subsystem and component levels of the plane.
The Centre would fund the programme, whose cost is said to run into several hundred crores.
The recruitment of scientists and engineers was on in a big way. Some non-resident Indians were also keen on working in the programme.
The DRDL, which powered the supersonic cruise missile BrahMos that travels at Mach 2, into space, had the wherewithal to work on hypersonic applications, Dr. Prahlada said.

Indian defence scientists are aiming to build a plane designed to cruise at speeds three times faster than existing fighter aircraft while consuming less fuel.
The Hyderabad-based Defence Research and Development Laboratory (DRDL) is building an 8metre technology demonstrator, which will be powered by a supersonic combustion ramjet (Scramjet) engine that takes oxygen from the atmosphere and burns liquid hydrogen.
"The ground tests of the engine would begin in 2005 and we aim to fly the unmanned aircraft in 2007," DRDL Director Prahlada told PTI in Bangalore.
The aircraft would be built in India's aviation capital, Bangalore, and Hyderabad. It would be a high speed transport aircraft with an engine that does not have a compressor or a turbine.
"The scramjet engine takes in oxygen from the atmosphere, liquefies it and uses it for the cryogenic engine, improving the efficiency of the plane by several factors because the weight of the fuel, particularly for long distances, constitutes around 70 per cent of the total weight of the aircraft," officials said.
The technology demonstrator would be a precursor to President A P J Abdul Kalam's dream project and DRDO's Aerobic Vehicle for Hypersonic Aerospace Transportation (AVATAR).
India has achieved considerable progress in the air breathing engine technology (ramjet) at sub-sonic speed in its surface-to-air Akash missile programme, but is yet to master the technology at supersonic speed of up to Mach 7 (speed of sound is referred to as Mach). "We are improving on our expertise in air breathing engine technology and it would be used in an unmanned aircraft," Prahlada said.
Incidentally, the country is in race with the US, Japan, Russia and China to build a hypersonic plane which is expected to revolutionise low cost space travel. The Indian Space Research Organisation has begun conceptual studies to build and launch a reusable launch vehicle using air-breathing technology by 2015, he said.
DRDL is jointly working with academic institutions, including the IITs and the Indian Institute of Science, besides collaborating with the Mishra Dathu Nigam (Midani) to develop high temperature Nickel-Cobalt alloys and carbon composite materials, which could withstand heat during high-speed flight of the hyper plane

The Indian Space Research Organisation (ISRO) has completed the ground-level trials of the air-breathing engine and is preparing to move into more advanced stages of development.
Special teams have been formed to prepare the indigenous system for its first flight. ‘‘We plan to put it on a sounding rocket instead of carrying it on an aircraft like NASA. The module will be launched at a height of 20-25 km at a speed of about Mach 6. It will draw oxygen from the atmosphere and convert it into fuel for further propulsion,’’ top sources said.
Through the Air-Breathing Propulsion Project (ABPP), being undertaken in Thiruvananthapuram, Indian space research will join the league of the US. Though many other countries attempted the concept, none had been successful.
‘‘We are happy with the ground tests. The system produced desirable floor rates. Next round of experiments will be held at the National Aeronautical Laboratory, Bangalore,’’ sources said.
The ISRO will also send a special team to the Liquid Propulsion Centre, Mahendragiri, for a crucial phase of the project. ‘‘This is injection of hydrogen into the system. During its supersonic flight, the technology will breath in oxygen. This will be mixed with hydrogen on board to create fuel for forward manoeuvres,’’ sources said.
The ABPP, also known as hyperplane, is intended at providing a most-efficient, technologically-reliable and cost-effective space launch system.
‘‘We have adopted a step by step approach. And the first strides have been quite satisfactory,’’ said G.Madhavan Nair, ISRO chairman. ‘‘The engine module has been satisfactorily tested at ground level. We are indeed hopeful of flying it in another 18 months’ time,’’ he said.
The ISRO is aiming to touch Mach 6 during the first flight. ‘‘We have demands for achieving Mach 10. This is, perhaps, the first step,’’ Madhavan Nair said.
The idea of using a two-stage sounding rocket is also to keep the costs down. The system may be accommodated in the second stage of the rocket that will effectively take it up to 25-km height. ‘‘The scientists have been able to hold combustion effectively. This, itself, is a significant landmark or a strong foundation for us to build further,’’ sources said.
India plans to use the hyperplane for cheaper satellite launches. A similar project, titled Avatar, is also being undertaken by the Defence Research and Development Organisation (DRDO). ‘‘Any rocket system will have military use also. So it’s not surprising,’’ sources quipped
