  An aerospace startup just won a contract to develop an Air Force One jet that can travel at Mach 5. Here's an early look at the engine that could rocket from New York to Paris in 90 minutes.

  David Slotnick 19 hours ago The Air Force One of the future might be getting a major speed boost. An aerospace company called Hermeus on Thursday announced a contract with the US Air Force and the Presidential and Executive Airlift Directorate to develop a hypersonic aircraft for the presidential fleet. While the next Air Force One, a modified 747-8, is due to be delivered by Boeing next year, the Hermeus contract looks toward its eventual replacement. Hermeus said it won the contract after designing, building, and successfully testing a prototype of an engine capable of propelling an airplane to Mach 5, or five times the speed of sound — about 3,300 mph. Mach 5 represents the delineation between supersonic and hypersonic speeds. The company completed those tests in March, Aviation Week reported. Hermeus plans to build a demonstrator vehicle over the next five years, with commercial aircraft envisioned in about a decade, Skyler Shuford, its cofounder and chief operating officer, said in 2019. A press release announcing the Air Force contract said part of the project would focus on integrating Air Force requirements into the airplane's designs. Hermeus emerged last year, announcing plans to develop a Mach 5 aircraft that could fly from New York to Paris in about 90 minutes. Ars Technica reported in May 2019 that the company raised an initial round of funding, led by Khosla Ventures, which it used to develop the prototype. Hermeus said it would use a turbine-based combined-cycle engine for the propulsion system, according to the report. The company's cofounders are alumni of SpaceX, Blue Origin, and the aerospace company Generation Orbit. At the time, Hermeus said it planned to use mostly existing technology and materials to achieve hypersonic travel. "We can make a vehicle fly that fast with today's technology," Glenn Case, a cofounder and the chief technology officer, said in a video published this spring. "We aren't getting into anything too miraculous," Shuford told Ars Technica last year. "We want to do engineering, not science." As of Thursday, the company listed about 10 open positions, including for airframe and propulsion engineers. https://www.businessinsider.com/hypersonic-air-force-one-hermeus-mach-5-2020-8

  Pentagon Creates ‘Do Not Buy’ List of Russian, Chinese Software

  Increasingly alarmed at foreign hacking, DOD and intelligence officials are racing to educate the military and defense contractors. The Pentagon is warning the military and its contractors not to use software it deems to have Russian and Chinese connections, according to the U.S. Defense Department's acquisition chief. Officials have begun circulating a “Do Not Buy” list of software that does not meet “national security standards,” Ellen Lord, defense undersecretary for acquisition and sustainment, said Friday. “We had specific issues ... that caused us to focus on this,” Lord told reporters at the Pentagon. “What we are doing is making sure that we do not buy software that's Russian or Chinese provenance,” she said. “Quite often that's difficult to tell at at first glance because of holding companies.” The Pentagon started compiling the list about six months ago. Suspicious companies are put on a list that is circulated to the military's software buyers. Now the Pentagon is working with the three major defense industry trade associations — the Aerospace industries Association, National Defense Industrial Association and Professional Services Council — to alert contractors small and large. https://www.defenseone.com/threats/2018/07/pentagon-creates-do-not-buy-list-russian-chinese-software/150100/

  FRANCE PLANS TO BOOST ITS SELF-DEFENSE POSTURE IN SPACE

  By: Christina Mackenzie PARIS – France has decided that by 2025 it will invest another €700 million ($780 million), in addition to the €3.6 billion ($4 billion) already earmarked, to boost its space capabilities, strengthening its means of surveillance and acquiring the means to self-defend in space. “If our satellites are threatened, we will blind those of our adversaries. We reserve the right to choose the time and means of the riposte: it could imply using powerful lasers deployed from our satellites or from patroller nano-satellites,” explained Armed Forces Minister Florence Parly on July 25. The announcement comes on the heels of the one made by President Emmanuel Macron on July 13 that a Space Command would be created on Sept. 1 in Toulouse, south-west France. Initially staffed by 220 people, it will be subordinated to the Air Force whose name will change to become the Air and Space Force (Armée de l'Air et de l'Espace). “Eventually, this command will be responsible for all our space operations, under the orders of the chief of staff of the armed forces,” Parly said at the Air Defense and Air Operations Command (CDAOA) on Airbase 942 in Lyon-Mont Verdun. She explained that “today our allies and our military adversaries are militarizing space. [...] We must act. We must be ready.” To this end she announced a new weapons program called “Mastering Space” with two major components: surveillance and active defense. France is one of the few countries to have its own space surveillance system thanks to the Graves and Satam radars and the telescopes deployed by the Ariane Group and the CNRS (the state-funded scientific research center). “The successor of Graves must be able to detect satellites 1,500 kilometers away that are no bigger than a shoe-box,” she declared. Actions would be taken to protect satellites, such as adding surveillance cameras to the Syracuse communications satellites and procuring patroller nano-satellites from 2023, according to the defense minister. Officials stress that this new strategy falls entirely within international legal framworks, which guarantee freedom of exploration and use of space as well as the principle of self-defense. However, France's own National Space Law will have to be adapted within an inter-ministerial framework in order to take account of the specifics of military space. https://www.defensenews.com/global/europe/2019/07/26/france-plans-to-boost-its-self-defense-posture-in-space/
