  Lockheed and Bell will compete head-to-head to build US Army’s future attack recon aircraft

  By: Jen Judson WASHINGTON — Sikorsky, a Lockheed Martin-owned company, and Bell have been selected to build and fly Future Attack Reconnaissance Aircraft (FARA) prototypes for the U.S. Army in a head-to-head competition, according to a March 25 Army statement. The Army is planning to procure both a FARA and Future Long-Range Assault Aircraft (FLRAA) that will slowly replace the current fleet of Sikorsky-manufactured UH-60 Black Hawks utility helicopters and Boeing-made AH-64 Apache attack helicopters. The service plans to initially field both in the 2030s. FARA will fill a critical capability gap currently being filled by AH-64E Apache attack helicopters teamed with Shadow unmanned aircraft following the retirement of the OH-58D Kiowa Warrior helicopters. The service has tried and failed three times to fill the gap with an aircraft. The Army had selected five teams to provide FARA designs last spring: AVX Aircraft Co. partnered with L-3 Communications Integrated Systems, Bell, Boeing, Karem Aircraft and Sikorsky. The Army laid out a handful of mandatory requirements that the vendors had to meet and also a list of desired requirements for initial designs, Col. Craig Alia, the Future Vertical Lift Cross Functional Team chief of staff, told reporters last year. The service also looked at the vendors' execution plans and evaluated timing as well as funding profile requirements. “The ones that were selected were clearly meeting the mandatory requirements and were in the acceptable risk level of the execution plan and the desired requirements," Dan Bailey, who is the FARA competitive prototype program manager, added. The prototype program falls under the purview of the Army Combat Capabilities Development Command Aviation and Missile Center's Aviation Development Directorate. Lockheed unveiled its design — Raider X — at the Association of the U.S. Army's annual conference in October 2019. The company's design uses its Raider X2 coaxial technology with a focus on how it will perform “at the X.” “One thing that always comes out is the importance of this aircraft at the X,” Tim Malia, Sikorsky's director of future vertical lift light, told Defense News in an interview last fall. “The ‘X' is defined by the Army as the terminal area where they actually have to go do the work, do the reconnaissance, do the attack mission. The operation at the X is really critical for this program and for this platform.” That's where Raider X comes in. It's a slightly larger version of the Raider coaxial helicopter that Lockheed has been flying for several years at its West Palm Beach, Florida, flight test center. “Through our mature S-97 RAIDER technology demonstrator, we continue to optimize our FARA solution, which will provide the Army with an integrated weapon system that combines speed, range, maneuverability, survivability and operational flexibility," Andy Adams, Sikorsky's vice president of future vertical lift, said in a March 25 statement. This approach is driving down risk and will result in an aircraft solution that is capable of executing the Army's joint all-domain operations." Bell revealed its design — the Bell 360 Invictus — which is based on 525 technology. But its design features several key differences, including its size in order to adhere to the Army requirement of 40-foot in diameter rotor blades. The design includes a single main rotor helicopter in a four-blade configuration, a low-drag tandem cockpit fuselage and transportability in a C-17. “Bell is proud to continue work on the Bell 360 Invictus as part of the Army's Future Attack Reconnaissance Aircraft Competitive Prototype competition,” Keith Flail, Bell's vice president of advanced vertical lift systems, told Defense News on March 25. “We have made significant investment and begun manufacturing in order to preserve the Army's schedule for FARA CP and we are thrilled to continue our work on the Invictus,” he said. “Bell's approach from the beginning has been tailored to deliver the advanced performance required without excessive complexity in order to get critical capability in the hands of the warfighter quickly and affordably.” The AVX and L3 team was the earliest to unveil its design for the FARA competition at the Army Aviation Association of America's annual summit in Nashville, Tennessee, in April 2019. The design uses AVX's compound coaxial and ducted fans technology. The companies said its single-engine design meets 100 percent of the Army's mandatory requirements and 70 percent of its desired attributes. Karem announced it would team with Northrop and Raytheon and came out with its design at AUSA — its AR-40 — with a single main rotor, tilting compound wings and a rotating tail rotor. Boeing was the last to reveal its design, coming out with it March 3. The company's clean-sheet design featured a hingeless, six-bladed, high-solidity main rotor; a four-bladed conventional tail rotor; and a propeller on the back. The prototype aircraft are expected to start flying in the fourth quarter of fiscal 2022, and the flight test is expected to run through 2023. The engineering and manufacturing development phase is expect to begin in FY24. https://www.defensenews.com/smr/army-modernization/2020/03/25/lockheed-and-bell-will-compete-head-to-head-to-build-us-armys-future-attack-recon-aircraft

  Here’s who will build and integrate the first hypersonic weapon system prototype

  By: Jen Judson WASHINGTON — Dynetics Technical Solutions will be the first to manufacture a set of hypersonic glide body prototypes while Lockheed Martin will serve as the weapon system integrator, according to a U.S. Army announcement. The other transaction authority, or OTA, contract awards mark an important step forward in getting a prototype of the Army's Long Range Hypersonic Weapon, or LRHW — capable of flying at five times the speed of sound — that will launch from a mobile ground platform fielded by fiscal 2023. An OTA is a congressionally mandated contracting mechanism that makes it easier to prototype capabilities. The Army's No. 1 modernization priority is Long-Range Precision Fires, and hypersonic development falls into that category. “Delivering hypersonics to a unit of action will provide a critical combat capability for the Army in support of the National Defense Strategy,” Lt. Gen. L. Neil Thurgood, director of hypersonics, directed energy, space and rapid acquisition, said in an Aug. 30 statement. “With a collaborative effort by our partners in industry and the Department of Defense, we will advance this strategic weapon system and fulfill a critical mission for our nation.” Dynetics, based in Huntsville, Alabama, will get $351.6 million to produce the “first commercially manufactured set of prototype Common-Hypersonic Glide Body (C-HGB) systems,” according to the statement. This means the company will get the first crack at building the C-HGB, but it is likely others will subsequently receive awards to learn how to manufacture the C-HGB developed by the federally funded Sandia National Laboratories in an effort to build up the currently nonexistent hypersonic industrial base in the United States. Dynetics and future award winners will work with the lab to learn how to build the C-HGB. As hypersonic missiles become a reality, industry must relearn how to effectively, efficiently and economically produce them. While companies have developed warheads, glide bodies and other components, there is no industrial base equipped to manufacture hypersonic weapons. By giving multiple companies a chance to learn how to build the glide body, the hope is the process will build that vital industrial base. Lockheed Martin will integrate a launcher that can accommodate the C-HGB onto a mobile truck. That contract is worth $347 million. The OTA awards cover the design, integration and production work that will bring about a series of flight tests starting in 2020, which will lead to a fielding of a prototype LRHW battery, consisting of four trucks, launchers, hypersonic missile rounds and a command and control system. The Army is in charge of producing the LRHW C-HGB as part of a collaboration with the other services. "Dynetics has been developing enabling technologies for many years,” Steve Cook, the company's president, said in a statement. “Our team is pleased the Army saw that our highly-skilled engineers and technicians can bring this technology rapidly and affordably to the warfighter.” DTS will lead “a world-class team for the project, including established and proven defense industry contractors” like General Atomics Electromagnetic Systems, Lockheed Martin and Raytheon. “Each of these companies will bring decades of experience and will join science and technological capabilities to make a modern prototype and eventually become a program of record,” Cook said. General Atomics Electromagnetic Systems will provide cable, electrical and mechanical manufacturing. Lockheed will support the manufacturing, assembly, integration, testing, systems engineering and analysis. And as a principal subcontractor, Raytheon will provide its “extensive experience” in advanced hypersonic technology to build control, actuation and power-conditioning sub-assemblies that control flight, and it will help assemble and test the prototype. Lockheed Martin's integration team also includes Dynetics, which will develop launchers with hydraulics, outriggers, power generation and distribution for the ground platform. Other members of Lockheed's team are Integration Innovation Inc., Verity Integrated Systems, Martinez & Turek, and Penta Research. “We believe our relationships offer the Army unmatched expertise and puts us in the best position to deliver this critical capability to the nation," Eric Scherff, vice president for hypersonic strike programs for Lockheed Martin Space, said in a statement. Lockheed Martin's hypersonic strike contract awards already exceed $2.5 billion. The Army plans to deliver a hypersonic missile and launcher to a unit in the fourth quarter of fiscal 2021. The unit will train for an entire year without live rounds, Thurgood said earlier this month at the Space and Missile Defense Symposium in Huntsville, Alabama. He noted that the canisters the unit will use will be filled with cement to match the weight. The first live-round test will take place in FY22 and will be conducted by a battery led by a captain. https://www.defensenews.com/land/2019/08/30/heres-who-will-build-and-integrate-the-first-hypersonic-weapon-system-prototype
