  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

  The Army is moving forward with its electronic warfare pod

  Andrew Eversden The Army has moved the Lockheed Martin-made electronic warfare pod to the build and evaluation phase of the operational system, as it bolsters its electronic warfare capabilities. The second phase agreement is worth nearly $75 million, according to the Consortium Management Group's Jan. 30 award listing, which made the award on behalf of the Army. Lockheed Martin's electronic warfare pod, known as the “Air Large” piece of the Army's Multi-Function Electronic Warfare family of systems program, is mounted on an MQ-1C Gray Eagle drone. It provides commanders with jamming capabilities as well as electronic support, or sensing of the electromagnetic spectrum. The defense contractor developed a prototype as part of the first phase of the project it won in January 2019 under an $18 million contact. “Our internal research & development programs have resulted in first-of-its-kind converged technologies that are at the forefront of realizing our customers' urgent need and vision for combined cyber and electronic warfare (EW) capability and dominance,” Deon Viergutz, vice president of Lockheed's Spectrum Convergence division, said in a statement. The company has been testing the pod as part of the Army's Cyber Blitz exercise. Army officials plan to have the capability deployed to combat aviation brigades in 2022. The pods are expected to play a critical role on the battlefield with near-peer adversaries, such as Russia and China. “The air pod solutions are very important, especially when you start going against a near-peer competitor. The main reason why is because you start now dealing with more of an [electronic intelligence] ELINT threat than with a strictly commercial threat,” Col. Kevin Finch, program manager for electronic warfare and cyber within Program Executive Office Intelligence, Electronic Warfare and Sensors, told C4ISRNET in October last year. https://www.c4isrnet.com/battlefield-tech/c2-comms/2020/04/29/the-army-is-moving-forward-with-its-electronic-warfare-pod
