The DARPA Falcon Project canceled

The DARPA Falcon Project (Force Application and Launch from CONtinental United States) is a two-part joint project between the Defense Advanced Research Projects Agency (DARPA) and the United States Air Force (USAF) and is part of Prompt Global Strike.

One part of the program aims to develop a reusable, rapid-strike Hypersonic Weapon System (HWS), now retitled the Hypersonic Cruise Vehicle (HCV), and the other is for the development of a launch system capable of accelerating an HCV to cruise speeds, as well as launching small satellites into earth orbit. This two-part program was announced in 2003 and continued into 2006.

Blackswift was a project announced under the Falcon banner using a fighter-sized unmanned aircraft which would take off from a runway and accelerate to Mach 6 before completing its mission and landing again. The memo of understanding between DARPA and the USAF on Blackswift—also known as the HTV-3X—was signed in September 2007. The Blackswift HTV-3X did not receive needed funding and was canceled in October 2008.

Current research under FALCON program is centered on X-41 Common Aero Vehicle (CAV), a common aerial platform for hypersonic ICBMs and cruise missiles, as well as civilian RLVs and ELVs. The prototype Hypersonic Technology Vehicle 2 (HTV-2) first flew on 22 April 2010; the second test flew 11 August 2011. Both flights ended prematurely.

Design and development

Past projects

The aim was always to be able to deploy a craft from the continental United States, which could reach anywhere on the planet within one to two hours. The X-20 Dyna-Soar in 1957 was the first publicly acknowledged program—although this would have been launched vertically on a rocket and then glided back to Earth, as the Space Shuttle does, rather than taking off from a runway. Originally, the Shuttle was envisaged as a part-USAF operation, and separate military launch facilities were built at Vandenberg AFB at great cost, though never used. After the open DynaSoar USAF program from 1957–1963, spaceplanes went black. In the mid-1960s, the CIA began work on a high-Mach spyplane called Project Isinglass. This developed into Rheinberry, a design for a Mach-17 air-launched reconnaissance aircraft, which was later canceled.

The 8 minute flight from LA to NY is still a dream.
8 minuutin lento LA;sta NY;iin jää vielä haaveeksi.
