Others would argue that Falcon—which has been allocated US$170 million for budget year 2008—and its predecessors maintain the United States' capability to develop a spaceplane quickly, should the need arise.

FALCON

The overall FALCON program announced in 2003 had two major components: a small launch vehicle

 for carrying payloads to orbit or launching the hypersonic weapons platform payload, and the hypersonic vehicle itself.

Small Launch Vehicle

The DARPA FALCON solicitation in 2003 asked for bidders to do development work on proposed vehicles in a first phase of work, then one or more vendors would be selected to build and fly an actual launch vehicle. Companies which won first phase development contracts of $350,000 to $540,000 in November 2003 included:

Hypersonic Weapon System

The first phase of the hypersonic weapon system development was won by three bidders in 2003, each receiving a $1.2 to $1.5 million contract for hypersonic vehicle development:
  • Andrews Space Inc., Seattle, Wash.
  • Lockheed Martin Corp., Lockheed Martin Aeronautics Co., Palmdale, Calif.
  • Northrop Grumman Corp., Air Combat Systems, El Segundo, Calif.


Lockheed Martin received the only Phase 2 HWS contract in 2004, to develop technologies further and reduce technology risk on the program.

Follow on hypersonic program

Following the Phase 2 contract, DARPA and the US Air Force continued to develop the hypersonic vehicle platform.

The program was to follow a set of flight tests with a series of hypersonic technology vehicles.

The FALCON project includes:

, an all-in-one power plant. The turbine engine accelerates the vehicle to around Mach 3 before the ramjet takes over and boosts the vehicle up to Mach 6." Dr. Stephen Walker, the Deputy Director of DARPA's Tactical Technology Office, will be coordinating the project. He told the USAF website,
The Falcon program has announced the hypersonic horizontal take-off Blackswift/HTV-3X. It is also launching the HTV-2 off the top of a rocket booster. Falcon seems to be converging from two directions, on the ultimate goal of producing a hypersonic aircraft which can take off and land from a runway in the USA, and be anywhere in the world in an hour or two. Falcon is methodically proceeding toward a Hypersonic Cruise Vehicle. Dr. Walker stated,


In October 2008 it was announced that HTV-3X or Blackswift did not receive needed funding in the fiscal year 2009 defense budget and had been canceled. The Hypersonic Cruise Vehicle program will continue with reduced funding.

 at Mach 20. The launch was successful, but the first mission was not completed as planned. Reports stated that contact had been lost with the vehicle nine minutes into the mission. In mid-November DARPA revealed that the test flight had ended when the computer autopilot had "commanded flight termination". According to a DARPA spokesman, "When the onboard system detects [undesirable or unsafe flight] behavior, it forces itself into a controlled roll and pitchover to descend directly into the ocean." Reviews found that the craft had begun to roll violently.

A second flight was launched on 11 August 2011. The unmanned Falcon HTV-2 successfully separated from the booster and entered the mission's glide phase, but again lost contact with control about nine minutes into its planned 30-minute Mach 20 glide flight. Initial reports indicated it purposely impacted the Pacific Ocean along its planned flight path as a safety precaution. Some analysts think that the second failure will result in an overhaul of the Falcon program.
