    Sikorsky Unveils Raider-X Proposal For FARA Armed Scout

    Graham Warwick Sikorsky is emphasizing growth capability to stay ahead of evolving threats as it unveils its offering in the U.S. Army's Future Attack Reconnaissance Aircraft (FARA) competition, the Raider-X. The coaxial rigid-rotor compound helicopter is a development of the S-97 Raider prototype now in flight testing. The Raider-X is about 20% larger, with a 14,000-lb. gross weight compared with 11,000 lb. for the S-97, and a 39-ft. rotor diameter compared with 34 ft. for the Raider. The Army requires a rotor diameter of no more than 40 ft. so that FARA can fly between buildings in urban combat. The Raider-X will exceed the FARA's threshold maximum speed of 180 kt. Sikorsky is not saying how fast it will fly, but notes the S-97 has reached 215 kt., and 207 kt. in level flight—exceeding the 205 kt. target in the Army's initial capability document, says Tim Malia, director of Future Vertical Lift - Light. The Army subsequently reduced the threshold maximum speed to enable a wider competition for the FARA program. But Malia says the greater speed and payload capability of Sikorsky's X2 coaxial rigid-rotor compound configuration compared with a conventional helicopter provides growth capacity. “We looked at a single main rotor helicopter for FARA, but it would be minimally compliant in the early 2020s. We need to be able to stay ahead of the threat into the 2030s and 2040s,” he says. Bell is proposing a winged, single-main-rotor helicopter for FARA, while AVX Aircraft is offering a coaxial-rotor, ducted-fan compound. Boeing and Karem Aircraft have yet to unveil their concepts. “Single main rotor will not be able to keep up. It's already tapped out meeting the minimal FARA requirements. It does not have the ability to grow capability over time,” Malia says. “We didn't want to pull out all the stops to be minimally compliant when we had X2 able to carry more payload and go faster.” The Raider-X has four-blade rotors and a pusher propulsor. The coaxial rotors generate lift only on the advancing sides, eliminating retreating-blade stall and enabling higher speed. At high speed, 90% of the engine power goes to the propulsor, says Bill Fell, senior experimental test pilot. The propulsor is declutched at low speed to reduce noise. The Raider-X closely resembles the S-97 prototype, with side-by-side seating. Compared with tandem seating, this improves crew coordination and situational awareness, Malia says. “And we can do it aerodynamically because of the robust performance inherent in X2. We are not trying to get out every last ounce of drag.” Behind the cockpit is a large internal weapons bay. Internal carriage of missiles and unmanned aircraft—which the Army calls air-launched effects (ALE)—is a FARA requirement, but Malia says the cabin-like volume of Raider-X's bay provides growth space for future, larger systems. “The minimum threshold works now, but what if in 2030 there is a new ALE that can be decisive, but can't be carried?” he asks. The Raider-X is powered by a single 3,000-shp-class General Electric T901 turboshaft—government-furnished equipment to all FARA bidders. “We do not have an additional engine to increase speed,” Malia says, referring to the supplemental power unit in Bell's 360 Invictus. This augments power from the single T901 to give the single-main-rotor, tandem-seat Invictus a 185-kt. maximum speed. “We use the power available and have a solid design built around it,” he says. “The T901 provides speeds out of the chute in excess of requirements and, as it improves, we can take direct benefit. We have a growth path to additional speed and payload as the T901 power increases.” Sikorsky is using the industry-funded S-97 prototype to reduce risk for its FARA bid, conducting flight testing to validate design models and optimize the Raider-X. This includes flying new rotor blades designed to reduce drag and vibration. “We are getting exactly the results the models said,” Malia says. With two rotor systems and a propulsor, Sikorsky is paying close attention to the Raider-X's cost. “We have done a complete affordability analysis and design to cost. We are extremely confident we will come in under the cost goal,” he says. Several divisions of parent company Lockheed Martin are part of Sikorsky's FARA team, Malia says, including Aeronautics, Missiles and Fire Control and Rotary and Mission Systems. Swift Engineering will build the airframe if Sikorsky wins one of two FARA competitive prototype contracts scheduled to be awarded in March 2020. The Army flyoff is planned for 2023, with the first unit to be equipped by 2028. “There is a critical cap in vertical lift, in attack/reconnaissance, and that gap is really impactful to the Army in the 2020s, ‘30s, ‘40s, even ‘50s. So there is a need for a long-term solution,” Malia says. “The threat is projected to evolve rapidly, so we require significant capability growth on our side to stay ahead. Raider-X can provide an asymmetric advantage in the 2030s-50s.” https://aviationweek.com/defense/sikorsky-unveils-raider-x-proposal-fara-armed-scout

  • China to sanction Boeing, Lockheed and Raytheon over Taiwan arms sales

    China to sanction Boeing, Lockheed and Raytheon over Taiwan arms sales

    Joe McDonald BEIJING — China's government said Monday it will impose sanctions on U.S. military contractors including Boeing's defense unit and Lockheed Martin for supplying weapons to rival Taiwan, stepping up a feud with Washington over security and Beijing's strategic ambitions. Raytheon Technologies Corp. and “relevant American individuals” associated with the sales also will be affected, said Foreign Affairs Ministry spokesman Zhao Lijian. He gave no details of what penalties might be imposed or when. The ruling Communist Party claims Taiwan, which split with the mainland in 1949 during a civil war, as part of its territory and has threatened to invade. Washington promised in the 1980s to reduce and eventually end weapons sales to Taiwan but insists its dispute with Beijing must be settled peacefully. “In order to safeguard national interests, China decided to impose sanctions on the American companies that were involved in arms sales to Taiwan,” Zhao said at a regular news briefing. Chinese-U.S. relations have plunged to their lowest level in decades amid disputes about security, technology, the coronavirus pandemic and human rights. Taiwan has long been an irritant in relations. Washington has no formal relations with the island's democratically elected government but is its main ally. U.S. law requires the government to ensure Taiwan can defend itself. Weapons sales to the island have increased in quantity and quality. Last week, Beijing demanded Washington cancel a planned sale of 135 precision land-attack missiles valued at more than $1 billion to improve its defenses. The sale “seriously undermined China's sovereignty and security interests,” Zhao said. China has stepped up military activity around Taiwan in an attempt to force concessions from the pro-independence administration of President Tsai Ing-wen. The Communist Party is using the mainland's growing economic weight to pressure other governments to cut diplomatic and unofficial ties with Taiwan. Beijing regularly pressures American companies, including Boeing, in an effort to influence U.S. policy. China is one of Boeing's biggest markets for commercial aircraft, which might make it vulnerable to a boycott, but Zhao mentioned only Boeing's military arm, Boeing Defense, not its civilian jetliner business. Lockheed Martin and Raytheon also supply radar and other technology for civilian aviation. The two governments have put sanctions on companies and individuals on both sides over complaints about human rights, computer hacking and other issues, though it is unclear whether they have any effect. Washington has imposed travel and financial bans on Chinese officials and companies it says are linked to abuses in the northwestern region of Xinjiang, where Muslim minorities have been detained in re-education camps, or Hong Kong after Beijing tried to tighten control by imposing a national security law. Beijing has retaliated by announcing sanctions against some U.S. legislators. Zhao called on Washington to “stop arms sales to Taiwan and stop any military interaction with Taiwan,” adding: “We will continue to take necessary measures to safeguard national sovereignty and security interests.” https://www.defensenews.com/global/asia-pacific/2020/10/26/china-to-sanction-boeing-lockheed-and-raytheon-over-taiwan-arms-sales/

  • Germany moves to protect its military-cyber industry

    Germany moves to protect its military-cyber industry

    Sebastian Sprenger MUNICH — A new German strategy document declares defense-related cyber technologies as key national assets, affording the domestic sector some protection from international competition. Government officials made the move with the publication of a paper this week outlining the types of technology Berlin wants to buy at home, in Europe or from global vendors. The designation of a key technology means the government can sidestep European Union rules requiring public acquisitions be open to companies throughout the bloc. The areas of artificial intelligence, electronic warfare, networked operations and cryptology, and defense-related information and communications technology are in the category deemed so crucial to national security that the government wants to keep the sector healthy. “A technological challenge for our security and defense lies in the area of digitalization and artificial intelligence,” read the strategy document, issued by the Ministry for Economic Affairs and Energy. “Maintaining cybersecurity is the prerequisite for the digital advancement of the state, the economy and society, and it is equally important for the sovereignty of Germany and Europe,” it added. The new designation of cyber technologies as worthy of special protection sets up a delicate dance between maintaining a national industrial ecosystem while remaining true to the idea of a European Union with a single market. German Defence Minister Annegret Kramp-Karrenbauer said her agency remains focused on cyber capabilities from a European perspective. For example, officials are working to ensure the relevant U.K. authorities remain plugged into EU networks after Brexit. The bloc, she said, must increase its cooperation on cyber issues, or risk falling behind China and the United States, Kramp-Karrenbauer said at the Munich Security Conference on Thursday. Germany's contributions to the NATO Very High Readiness Joint Task Force drives the country's plans for fielding a new information backbone for the land forces of the Bundeswehr, she said. In that context, officials have begun studying new approaches to managing the electricity required to power new communications kit on the battlefield, the minister added. It remains to be seen how the government will use the new strategy document on key national technologies to make investment decisions, said Matthias Wachter, a defense analyst with the Federation of German Industries, or BDI. For example, the stated domestic preference in electronic-warfare technology will be put to the test with the Air Force's upcoming buy of new aircraft for electronic warfare, Wachter said. In the running are the Airbus-made Eurofighter as a local option and the Boeing F-18 Growler from the United States. “There is nothing legally binding” in the new document, the analyst said, which means the decision could go either way. “But if you take the paper seriously, the Growler would be out.” https://www.fifthdomain.com/smr/munich-security-conference/2020/02/14/germany-moves-to-protect-its-military-cyber-industry/
