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
Lockheed Martin Solar and Astrophysics Laboratory or mitigate such impacts, and how to respond to them. An understanding of space weather and – in particular – its impacts on society are in their infancy, but there is broad agreement that societal sensitivity to high-impact, low-frequency events is obviously substantial. Equally important is the need to thoroughly investigate how space weather impacts various components of our high-tech society, and identify the mechanisms by which it does so.
