LOL, I'll believe it when I see it. This story sounds like a hoax. SR-72? LOL, look at this: http://www.apogeerockets.com/SR72_Darkbird_Kit.asp
Surely they are working on more capable things for intelligence. But this story is just a lame speculation.
The new jet — being referred to by some as the SR-72 — is likely to be unmanned and, while intended for reconnaissance, it could eventually trade its sensors for weapons.
Yeah, just like the SR-71 did...not.
Gripen, there's a huge difference between NASA research projects and actual defence projects for operation.
Aurora, 15 years later, still nothing more than speculation with very little evidence since the initial reports.
Maybe, we should tell the author of that story to do a similar report on a secret MiG-25 replacement, called the MiG-45, which can do Mach 6, and the engines made by Tumansky will tear up at full power. Developed in cooperation with Tupolev, it will be the world's biggest combat aircraft ever and be flown by former Tu-160 crew. It is nicknamed Firefox by NATO and the prototype will be named Clint Eastwood. It incorporates MiG-1.44 stealth and Su-47 design. It will be armed with ASAT missiles, designed to take out US spy satellites, and K-37XXX 'Almighty' missiles to shoot down the SR-72 . Also it has special anti-Patriot missiles in the tail, also called Patriotovski's by some sources. The intelligence gathering sensors are all copies of US systems, which leaked to Russia via Iran, Cuba and the Netherlands, it also has equipment to poison ex-KGB spies that live in London, but for this operation Putin needs to verify the launch codes which are kept at one of this dacha's. India will be the first export customer, because it has retired the MiG-25, but its replacement spy satellites are crap. It will be produced under license by HAL. Pakistan has signed up in China's J-XX development to counter the threat. Chavez has already expressed interest, but Putin said he first needs to increase the oil supply by 300% before they can talk. Tupolev is planning to make a commercial derivative of the plane to compete with Boeing's supercruiser, Aeroflot doesn't have the cash, but Singapore airlines plans to cancel their A380 contracts and commit to the project. Also stressed by this threat are South Korea and Japan, both have requested F-22 Raptors from Bush, but Bush said they can only get Raptors if they come to his ranch in Texas and win the rodeo.
Oh, and don't bother asking Putin or any CEOs about this, as it is policy not to discuss secret projects.
