One of the biggest changes in DARPA's budget for the next fiscal year is the ramping up of the Blackswift project. The agency will dump $70 million (?) next year into a joint effort with the Air Force to build an aircraft that can go six times the speed of sound -- and land on a runway, just like a normal plane. The idea is to use a combination of turbines and ramjets to fly so quickly. But it won't be easy. Outside of a few demonstration projects, pretty much the only things that go that fast today are ICBMs and spaceships, taking off and returning to earth.
AIR FORCE Magazine 22 / April 2008
The Department of Defense in February unveiled a project—named Blackswift— to mature technologies that would
enable aircraft to cruise at many times the speed of sound.
Blackswift is an outgrowth of Defense Advanced Research Projects Agency’s Falcon initiative under which the agency is developing hypersonic technologies applicable to future Air Force long-range strike and space-access systems.
Under Blackswift, engineers are creating a reusable flight vehicle, about the size of an F-16 fighter, that is known as of tactics for a hypersonic airplane that includes a runway takeoff, Mach 6 cruise, and runway landing.”
HTV-3X will be powered by a combined- cycle propulsion system comprising a high-speed turbine engine for the lower echelons of speed and a supersonic combustion ramjet to achieve the hypersonic rates.
To work, a decoy would have to be exactly the same size, shape, weight, weight distribution, appearance, thermal characteristics and thermal distribution as a real warhead
KJ_Lesnick said:Regarding the The Nike-Zeus/Spartan, it must have had some incredible altitude, range and speed if it could hit the bus before it unloaded its warheads.

The industry day briefing begins with a review of the problem - how to accelerate a hypersonic vehicle from zero airspeed to the Mach numbers needed to fire up a supersonic-combustion ramjet. It includes a couple of interesting slides on the HTV-3X flight demonstrator conceived by Lockheed Martin's Skunk Works under DARPA's Falcon program.
