Lockheed Martin SR-72 have the same range, with entry into service by 2030. The SR-72 follows the US Air Force's hypersonic road map for developing a hypersonic strike weapon by 2020, and a penetrating ISR aircraft by 2030. At the time of the concept's unveiling, Lockheed Martin had engaged in talks with government officials, but has not secured funding for the demonstrator or engine. On 13 November 2013, Air Force Chief of Staff General Mark Welsh revealed that the service was interested in the SR-72's hypersonic capabilities, but had not spoken with Lockheed Martin about the aircraft. Its high speed appeals to the
Project Scorpion to have been invited to participate. As from 2010, it would appear that the United States (DOD) and France (DGA) are the lead-players in the multinational Project Scorpion coalition. Project Scorpion uses part of the system of systems principles. Such military modernization efforts are part of a wider military concept of Revolution in military affairs, or "RMA". Larger defense companies serving as lead-system integrators for Project Scorpion include Northrop Grumman/EADS, Raytheon/Thales and General Dynamics, SAIC, SAGEM, Lockheed Martin Marietta and Boeing. Budget outlays for Project Scorpion are quite large - ranges of billions of dollars (and Euros) in various countries.
