  MDA pauses defensive hypersonic missile design to refocus plan

  By: Jen Judson   WASHINGTON — The Missile Defense Agency has paused its effort to design a defensive hypersonic missile and wants to refocus its plan of attack by concentrating on near-term options that could feed into a more “elegant” solution, according to Vice Adm. Jon Hill, the organization's director. The agency tapped industry in January to design and build an interceptor capable of defending against regional hypersonic weapons threats, releasing a draft request for proposals to build prototypes. The request directed industry to submit whitepapers by March 19 to build a Hypersonic Defense Regional Glide Phase Weapons System interceptor. The plan then was to select at least one prime contractor to build prototypes that would culminate in a flight test, according to the draft RFP. But last month, the agency updated its posting on the federal government's contract opportunities website and said the final solicitation was under review. It also said the agency was assessing COVID-19 impacts, technology maturation efforts, threat analyses, and empirical data from the recent joint Defense Department hypersonic testing in March “to accurately establish the technical baseline and future end-state for hypersonic missile defense and the (RGPWS) effort.” Agency leaders said they expect to complete the review by the end of the first quarter of fiscal 2021. “One of the reasons we took the pause and said, ‘We'll get back to you later in the year,' is we want to see what we can do in the very near-term, and I'll define the near-term as the mid-20s, and then feed the science and technology investments going so you can get to that farther-term, more elegant solution,” Hill said at the virtual Space and Missile Defense Symposium Aug. 4. “But we want to get that capability out there as soon as possible to defend against the hypersonic threat and we want to continue to build out that capability and we believe the glide phase, further back in that trajectory, is always better than the terminal systems that we got today,” Hill added. He noted that the capability to take out threats in the terminal phase of flight is still critical. But, “you will want to move back that trajectory as far as you can,” he said. Achieving “glide phase” defensive capability could come through a variety of technologies, he said, including different warhead types, different effector types and what kind of propulsion is used to get there. MDA is on a long-term path to achieving hypersonic defensive capability, but it is focused first on its Hypersonic and Ballistic Tracking Space Sensor (HBTSS), according to Hill. “That is number one, we have got to be able to sense, detect and get tracking and fire control information down to the shooter,” he said. As the agency went through its analysis of alternatives for a defensive hypersonic interceptor, “we recognized there are two paths you can take to get to a weapon system,” Hill said. MDA is going to build off its command-and-control battle management and the effectors it has in place, Hill said, adding the agency can take advantage of terrestrial-based and mobile sea-based sensing today to get tracking data and push it where it needs to go. “The question is how long do you stay in the science and technology world? You should also take a look at a quick development path and that is what we are looking at now,” Hill said. https://www.defensenews.com/digital-show-dailies/smd/2020/08/04/mda-pauses-defensive-hypersonic-missile-design-effort-to-refocus-plan/

  U.S. arms makers and medical device firms team up to make ventilators

  WASHINGTON (Reuters) - U.S. weapons makers have teamed up with medical device companies to increase the supply of ventilators that can be used to combat the coronavirus pandemic, people working on the project said. The two groups do not regularly partner on projects, but when a defense industry consultant with an engineering background realized weapons makers could help solve supply-chain problems within the U.S. ventilator industry, the creation of Vent Connect was set in motion and is set to be announced on Monday, the people said. The idea gathered momentum when industry associations like the Aerospace Industries Association, which represents plane makers and defense contractors including Lockheed Martin Corp (LMT.N) and General Dynamics Corp (GD.N), teamed up with AdvaMed, the Advanced Medical Technology Association, whose members include vent manufacturers. A handful of ventilator makers including ResMed Inc (RMD.N), and Zoll, an Asahi Kasei Corp (3407.T) company, post requests in the ventilator parts marketplace to a group of 60 weapons and airplane makers to help meet surging demand for the life-saving machines, an AdvaMed representative said. Working since March to cut through challenges as varied as how to handle intellectual property, confidentiality issues, cybersecurity and logistics, the two associations created the marketplace that is now serving as a new avenue for the ventilator supply chain. The defense companies involved in the project did not want their names published because they did not want to appear to seek credit for their efforts. At its outset, the task was gargantuan. One ventilator maker, Medtronic (MDT.N), released a parts list with over 1,500 items to see if there was any crossover with the defense supply chain, two of the people said. Alphabet Inc's Google (GOOGL.O) was brought in to help set up a website so that the companies could better coordinate online. The two industries share some common equipment. For example, fighter jets use pressure sensors to regulate oxygen to their face masks, which are also a key element in a ventilator to ensure that the rhythm of a patient's breathing pattern is monitored and maintained for the person's comfort. The efforts to try to stem the ventilator shortage are being worked on by the U.S. Army as well. In mid-April, Army Secretary Ryan McCarthy offered an investment of $100,000 to innovators who could come up with a “rapid ventilator production system to support field hospitals that are still requiring critical infrastructure.” https://www.reuters.com/article/us-health-coronavirus-industry/u-s-arms-makers-and-medical-device-firms-team-up-to-make-ventilators-idUSKBN22G12C

  FVL: Army Picks Bell & Sikorsky For FARA Scout

  The Bell 360 Invictus and the Sikorsky Raider-X will vie for the final contract to build FARA, with rival prototypes in flight by 2023. Bell and Sikorsky (with Boeing) are also facing off for the FLRAA transport. By SYDNEY J. FREEDBERG JR WASHINGTON: The Army has now narrowed its future aircraft choices to Sikorsky vs. Bell. This afternoon, the service announced that it had picked Sikorsky and Bell to build competing prototypes for Future Attack Reconnaissance Aircraft (FARA), a high-speed optionally manned scout to replace the retired Bell OH-58 Kiowa. Just eight days ago, it picked the same two firms – plus aerospace giant Boeing, acting as Sikorsky's de facto junior partner – to compete for the Future Long-Range Assault Aircraft (FLRAA), which will replace the Sikorsky's UH-60 Black Hawk as the military's aerial workhorse for everything from Ranger raids to medevac. The FLRAA transport decision was no surprise. The Army picked the two teams it had been funding for years to develop prototypes, the Bell V-280 Valor tiltrotor and the Sikorsky-Boeing SB>1 Defiant. There was more uncertainty over the FARA scout, because the service had given five companies Other Transaction Authority contracts to develop designs. Of those five, only Sikorsky had built and flight-tested an actual aircraft, the S-97 Raider, of which its Raider-X design is basically a super-sized version. Sikorsky and Bell now get to build FARA prototypes, while AVX, Boeing, and Karem have been cut. While AVX and Karem are design houses that have never built an actual aircraft, Boeing is a major aerospace player for which this is just the latest in a series of blows. Sikorsky and Bell have taken starkly different approaches to Future Vertical Lift. For both the FARA scout and the FLRAA transport, Sikorsky is offering its signature compound helicopters, descended from its record-breaking X2, that use a combination of ultra-rigid coaxial rotors and a pusher propeller to overcome the aerodynamic limits that cap the speed and range of traditional helicopters. No compound helicopter has ever entered mass production, but Sikorsky has built and flown two S-97 prototypes and, with Boeing, the much larger SB>1 Defiant: Raider-X will fall between the S-97 and SB>1 in size. Bell's marquee technology is the tiltrotor, most famously the widely used V-22 Osprey, using two massive rotors that tilt forward like a propeller for level flight and upwards like a helicopter for vertical takeoff and landing. It's a next-gen tiltrotor, the V-280 Valor, that Bell is flying for FLRAA. But Bell couldn't scale down their tiltrotor design – whose side-by-side rotors inevitably make for a wide aircraft – enough for the Army's FARA scout, which is meant to fly down city streets in urban warzones. So instead, their Bell 360 Invictus is, in essence, a streamlined conventional helicopter with wings: It has a single main rotor and a tail rotor, just like the old Kiowa, but it adds winglets to help with lift for high-speed fleet. Sikorsky argues their compound helicopter configuration is inherently much more efficient, pointing out that Bell's design requires more horsepower to achieve the Army's required speeds. Bell argues their time-tested single-main-rotor configuration will be less risky to develop, cheaper to buy, and easier to maintain. They each have three years to prove their case to the Army. https://breakingdefense.com/2020/03/fvl-army-picks-bell-sikorsky-for-fara-scout
