New-York to Los Angeles in 12 minutes… It would have been a record-breaker, had it worked:

The DARPA and USAF FALCON project might give anybody the thrill of speed as this « aerospacecraft » has been designed to reach Mach 20 i.e. around 20,000 km/h; 5.6 km/s; 10,800 knots; or 12,400 mph depending on the air temperature, and the altitude which might be above at least FL900!

Unfortunately, the project seems to encounter major difficulties as the last test which unfolded on August 11, 2011 failed again. The previous one – also on an HTV2 – had failed in April. Click on the right-hand side picture to get further information on the first test. The Blackswift (HTV-3X)  had been designed by ATK; Boeing; Lockheed Martin; and Skunk Works to provided a strategic strike anywhere in the world within an hour. It was cancelled due to a lack of funds (see the HTV-3 shown in the following video):



  • DARPA stands for Defense Advanced Research Projects Agency
  • FALCON stands for Force Application and Launch from CONtinental United States
  • FL stands for Flight Level (FL x 100ft = altitude)
  • HTV stands for Hypersonic Test Vehicle or Hypersonic Technology Vehicle
  • RCS means here in the videos: Reaction Control System (and not Radar Cross Section)

FLYING from Paris to New-York in 1.5 hours at Mach 4 !

This is the brand new project being designed by EADS, and supported by Japan as well as the French DGAC (Direction Générale de l’Aviation Civile – FAA or CAA equivalent). The European consortium has just unveiled its ZEHST project as the Paris Air Show 2011 is opening. ZEHST stands for Zero Emission Hypersonic Transportation.

This aircraft would be both a commercial airplane, and a rocket. It could cruise at « flight level 1056 » i.e. 20 miles or 32 kilometers above the mean sea level… The ZEHST specifications feature a speed of Mach 4 but according to the video below, it might reach Mach 4.5 i.e. 5,500 km/h or 3,000 kts through the stratosphere. It would use two independent turbojets for taking off, then it would gain speed thanks to two cryogenic rocket engines, finally two ramjets would propell the aircraft to hypersonic speeds.

The ZEHST is supposed to pollute far less than the Concorde as it would have a main cruise stage in the stratospheric layers, and according to EADS, its carbon footprint should be very low. There could between 60 and 100 passengers on board who could join Tokyo from Paris in 2.5 hours instead of 11.5, and New-York in 1.5 hours instead of 8! The prototype is expected to fly by 2020, and the first passengers might enjoy stratospheric flights around 2050.

X-51A WaveRider speed duration record at around Mach 5 – May 26, 2010

The X-51A WaveRider maintained its speed for more than 3 minutes. The X-43A reached the speed of Mach 9.8 in 2004. However, that top speed lasted for only 10 seconds.

« The X-51 launched at about 10 a.m. from here, carried under the left wing of an Air Force Flight Test Center B-52 Stratofortress. Then, flying at 50,000 feet over the Point Mugu Naval Air Warfare Center Sea Range, it was released. Four seconds later an Army Tactical Missile solid rocket booster accelerated the X-51 to about Mach 4.8 mach before it and a connecting interstage were jettisoned. The launch and separation were normal », Mr. Brink said. ( courtesy)
