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.

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.

New Army cyber gear for drones and teams test, protect units in another domain
By: Todd South A prototype device used recently at the Army's premiere combat training center has soldiers using precision cyber techniques to target small drones that might have been missed with other equipment and methods. Soldiers with the 3rd Brigade Combat Team, 1st Cavalry Division used the cyber precision drone detection system during a January rotation at the National Training Center. The equipment allowed soldiers to get alerts of drone presence and ways to target it that helped protect the brigade, according to an Army release. Capt. Christopher Packard said the prototype integrated with existing signal, intelligence and electronic warfare capabilities. Five soldiers embedded with the opposing force to attack the brigade with enemy drones for more realistic training, according to the release. A group of software developers at the Army's Cyber Command along with others at the Defense Digital Service built custom software and modified commercial equipment to make the early versions of the prototype last year. “The (Rapid Capabilities and Critical Technologies Office) and Tobyhanna (Army Depot) helped out with taking it from an advanced prototype and turning it into an engineering design model,” said 1st Lt. Aneesh Patel, with ARCYBER's Cyber Solutions Development Detachment with the 782nd Military Intelligence Battalion, 780th Military Intelligence Brigade. “We designed our own hardware and schematics, but what we didn't have was the proper ability to scale, and I think that's important in a bridging strategy and for any prototype.” The system is an “interim solution,” according to the release. “Being a newer system and a new tool for a maneuver unit, there are going to be a lot of things we don't know as [cyber] engineers, and a lot of their specific needs for the capability that may not have gotten through to us. So being out there was very important to this and any other project like it,” Patel said. The system will be followed by an upgraded version slated for Special Operations Command for an operational assessment this summer. Phase two will maximize the capability's operational life span by adding software updates that improve performance, according to the release. That type of equipment hits drones, but the Army also has its own cyber protection teams, such as the one featured in another release out of Grafenwoehr, Germany in June, where the 301st and 172nd CPTs used defensive measures for the Sabre Guardian 19 exercise. The annual exercise is taking place this year in Bulgaria, Hungary and Romania, co-led by the Romanian Joint Force Command. The teams “create chaos by accessing the network and either disabling it or stealing classified information and using it against the units involved in the exercise.” Though cyber threats have been a talking point among commanders for years, it wasn't until this most recent rotation that cyber threats were simulated for the exercise, said Capt. Joe McNerney, 301st CPT battle captain. The captain explained that the CPTs simulate an insider threat. The 172nd is a combination of soldiers and airmen from units based in Indiana, Michigan and Ohio. The 301st is an Air Force unit out of the Battle Creek Air National Guard Base, Michigan. “They're people we work with on a daily basis so we want to beat them," said Sgt. Brian Stevens, an information technology specialist from Detroit. “We have to make them feel pain at some level.” https://www.armytimes.com/news/your-army/2019/07/15/new-army-cyber-gear-for-drones-and-teams-test-protect-units-in-another-domain/
