FARA: Five-Way Fight For Army’s Future Scout

By SYDNEY J. FREEDBERG JR.

WASHINGTON: After four decades of failed attempts to replace its Vietnam-vintage OH-58 Kiowa scout, next month the Army will choose two of five competing teams to build prototypes for a new Future Attack Reconnaissance Aircraft.

Those prototypes, in turn, will compete for a mass-production contract in a 2023 “fly off,” with deliveries no later than 2028. A new scout is urgently overdue as the US faces ever-more-sophisticated Russian and Chinese air defenses that can keep traditional aircraft at bay. But with limited budgets, the Army will have to pick and choose high-priority units to get FARA first, and the rest of the force will have to wait.

“We've got to look at, where are the most critical spots to bring capability,” said Brig. Gen. Michael McCurry, director of aviation for the Army Deputy Chief of Staff for operations and plans. The priority is the cutting-edge combat units that must break open sophisticated anti-aircraft defensives for the rest of the force to follow, he told me: “That penetrate force, that's where FARA is going to go.”

Learning From the Past

Now, the Army has made its job easier in a couple of important ways. Perhaps most important, instead of the traditional dozens or hundreds of detailed technical specifications that hem in designers' ingenuity, Future Vertical Lift director Brig. Gen. Walter Rugen told me, “we have very few critical attributes within our FARA spec.”

One huge thing that the Army is not asking for: stealth. Unlike the costly Boeing Comanche cancelled in 2006, the FARA won't have to be shaped and coated to be impervious to radar – which is largely irrelevant to low-flying helicopters hiding behind hills, trees, or buildings, which are most often detected by the sound of their rotors, not by radar. Like the Comanche, advertised as a “digital quarterback,” FARA will act as an electronic hub for battlefield intelligence, collecting target data from drones and passing it to Army artillery, hypersonic missiles, and Air Force strike fighters – but network tech has come a long way since 2006, the year before the iPhone went on sale.

Finally, unlike the Comanche, FARA won't be a conventional helicopter with a single main rotor and a small tail rotor for stability. The speed and range required to survive the future battlefield are greater than that classic set-up can achieve. That's driven all four firms who've discussed their designs in public – Boeing has not revealed anything – to adopt innovative configurations the Army's never fielded before. Only one of the designs, Sikorsky's, is based on an existing aircraft that's done actual flight tests.

But the Army is confident the competitors can deliver. In detailed modeling, Rugen said, “all those offerings are beating those [minimum] mission critical attributes that we're trying towards.”

Congress actually cut the FARA budget for 2020 by $34 million. That won't slow the program down, the Army has said, but it will reduce the amount of Government Furnished Equipment (GFE) the service can provide the contractors to build their prototypes around: weapons systems including a 20-millimeter autocannon and a missile launcher, Modular Open Systems Architecture (MOSA) electronics, and the GE Improved Turbine Engine. To simplify and speed up development, all the competitors are required to include these standard-issue systems in their design — but the aircraft they build around them are radically different.

Design shop AVX has proposed an aircraft with two helicopter-style main rotors for vertical takeoff, wings for extra lift, and a pair of their characteristic ducted fans for speed. AVX, founded by Bell alumni, has never built an actual aircraft. But it's backed by the manufacturing might of the much larger L3Harris, a firm created by the merger of the 18th and 26th-largest defense contractors in the world (as per their 2019 rankings on the Defense News Top 100).

By contrast, Bell – part of Textron, No. 34 on the Top 100 – is a major builder of both military and commercial helicopters, as well as the revolutionary V-22 Osprey tiltrotor, from which the company's contender for the Army's future transport aircraft, the V-280, derives. Ironically, the Bell 360 Invictus is the most conservative-looking of the four known FARA designs: It's a streamlined single-main-rotor helicopter (looking kind of like Comanche) with the addition of two short wings for extra lift. Inside the aircraft, though, Bell is using new fly-by-wire flight controls and other technologies developed for its civilian Bell 525.

Aerospace giant Boeing – No. 2 of the top 100, counting its defense contracts alone – builds the Army's current mainstay armored gunship, the AH-64 Apache; its heavy lifter, the CH-47 Chinook; and, with Bell, the V-22 tiltrotor. But Boeing, which built the stealthy Comanche, is so far in public-relations stealth mode on FARA, declining to discuss its design.

Karem Aerospace is another design shop with an excellent pedigree – its founder is the father of the Predator drone – but no track record of actually building an aircraft. However, it's partnered with Northrop Grumman (No. 3 of the top 100) and Raytheon (No. 4) for this program, giving it serious manufacturing heft. The Karem AR-40 design has a unique combination of a single main rotor on top, a propeller at the tail that can swivel to act either as a tail rotor for stability or a pusher propeller for thrust, and wings that can tilt for the optimum aerodynamic angle in different modes of flight.

Last in the alphabet, comes Sikorsky, the helicopter division of the world's biggest defense contract, Lockheed Martin. While Sikorsky's Raider-X design hasn't flown yet, it's essentially a 20 percent larger version of the two S-97 Raiders the company built and flight-tested at its own expense. (One of them was totaled in the process, thankfully with no loss of life). And Sikorsky already knows how to upscale its compound helicopter technology, because there's already an even bigger member of the family, the Sikorsky-Boeing SB>1 Defiant, now in flight tests for the Army's Future Long-Range Assault Aircraft (FLRAA).

All these aircraft derive from the Collier Trophy-winning X2 and share its configuration: two main rotors on top, using ultra-rigid blades to provide maximum lift with minimum vibration at high speeds, and a single pusher propeller at the tail. Between the X2, the S-97, and the SB>1, Sikorsky's configuration has been through far more flight testing than any of its competitors on FARA.

So which team has the best combination of innovative design, proven technology, and the manufacturing muscle to build it at a price the nation can afford? That's a call the Army will make, and soon.

Japan names contractor to build its future fighter jet
By: Mike Yeo MELBOURNE, Australia — Japan has named Mitsubishi Heavy Industries as the prime contractor to build its next-generation fighter jet, with the Defense Ministry announcing earlier Friday that it signed a contract with the company. “We will steadily proceed with the development of the next fighter (F-X) together with the company,” the ministry said in a brief statement posted on it website. Local media is reporting Defense Minister Nobuo Kishi said the country will select an overseas partner by the end of this year for collaboration on aircraft technology, with stealth technology being one area of focus. The selection of MHI as the prime contractor for the F-X program comes as little surprise, given Japan was determined to restart its indigenous fighter aircraft capabilities. The company is the only one in Japan with experience in this area. The firm took the 21st spot on Defense News' most recent ranking of the top 100 defense companies in the world. Reuters previously reported the contract for the aircraft is worth up to $40 billion. Defense News emailed the Defense Ministry's Acquisition, Technology and Logistics Agency for an update on the contract value but did not receive a response by press time. The Defense Ministry is also seeking more funding for F-X research and development in its latest budget request submitted to the country's Finance Ministry in late September. The Defense Ministry requested $555.8 million for the main program and an additional $113.6 million for R&D of fighter subsystems, such as radars and mission systems integration. The funding will allow Japan to continue its R&D work into fighter technology, which it has kept up over the past decade despite the end of production on the Mitsubishi F-2 fighter jet and the decision to buy the Lockheed Martin F-35. Work the country plans to continue includes the development and refinement of stealth designs and materials, active electronically scanned array radars, and afterburning turbofan engines. Toward that end, local engine manufacturer IHI is expected to continue work on its XF9-1 afterburning turbofan. Japan conducted a series of test flights of a locally designed and built fighter technology demonstrator from 2016 to 2018 to validate its work. The country used the data gleaned from the test program to further refine its indigenous capabilities. The ministry previously said it wants to launch the basic design process for the F-X airframe and engine before the end of the current Japanese fiscal year, which ends March 31, 2021. This would be followed by the production of the first prototype, which is planned to begin in 2024, with flight tests earmarked to start in 2028 following finalization of the design and production plans. Japan plans to replace its fleet of approximately 90 F-2 jets with the new fighter jet starting around 2035. The F-2 was developed in conjunction with Lockheed in the 1990s, and resembles a larger version of the American company's F-16 multirole fighter but is primarily equipped with indigenous systems. Japan also plans to acquire 147 F-35s, which will include 42 of the short-takeoff-and-vertical-landing variants. That version, the F-35B, will operate from a pair of helicopter destroyers currently undergoing modifications to handle the jet. Japan also recently selected Boeing to upgrade 98 of its license-built Mitsubishi F-15J/DJ Eagle interceptors that will see the jets fitted with newer radars and integrated with standoff land-attack missiles. https://www.defensenews.com/industry/2020/10/30/japan-names-contractor-to-build-its-future-fighter-jet/

Cyberdéfense : la France, «nation la plus forte dans l’Union européenne»
Défense Cyberdéfense : la France, «nation la plus forte dans l'Union européenne» Le général de division aérienne Didier Tisseyre, commandant de la cyberdéfense, s'exprime dans La Tribune. Il estime que la France est «la nation la plus forte dans l'Union européenne» dans le domaine de la cyberdéfense. Il relève notamment que la France a su rester souveraine sur le plan du chiffrement : «ce sont des chiffreurs français, avec des composants français, toute une procédure française», note-t-il. La France s'est dotée d'une doctrine de lutte informatique offensive à des fins militaires. Pour le général, «celui qui maîtrisera le cyberespace aura un avantage, non seulement pour se protéger, mais aussi pour assurer sa supériorité opérationnelle». Une supériorité opérationnelle qui peut être remise en question avec les nouvelles technologies comme l'intelligence artificielle : «nous avons bien conscience des enjeux et travaillons énormément dans le domaine des IA», assure le général Tisseyre.

Despite some opposition, US on course to deliver F-35s to Turkey on June 21
WASHINGTON — The U.S. government is proceeding with plans to deliver the first F-35 to Turkey, with the country set to accept its first jet on June 21 despite opposition from some in Congress. A Lockheed Martin spokesman confirmed to Defense News that it's still gearing up for a rollout ceremony at its production facilities in Fort Worth next week. “The F-35 program traditionally hosts a ceremony to recognize every U.S. and international customer's first aircraft. The rollout ceremony for Turkey's first F-35 aircraft is scheduled for June 21,” the spokesman said in a written statement to Defense News. “The aircraft will then ferry to Luke Air Force Base, Arizona, where Turkish pilots will join the F-35A training pool.” The Senate is set to vote this week on the annual defense policy bill, which includes language that would prohibit the U.S. government from “transfer of title” to Turkey until the time that the Defense Department submits a report to Congress on removal of Turkey from the F-35 program. But even if that language succeeds in the Senate, the defense policy bill will proceed to conference, where a group of armed services committee members will hammer out differences between the House and Senate versions to emerge with a single, final piece of legislation. That process could take months. Congress's opposition to allowing Turkey to purchase the F-35 hovers around two points: the country's detainment of American pastor Andrew Brunson and a deal to purchase the Russian S-400 air defense system. But for now, it appears that the Defense Department has no plans to keep Turkey from getting its first F-35 or to put restrictions on its use at Luke AFB. Thomas Goffus, the Defense Department's deputy assistant secretary of defense for Europe and NATO, acknowledged during an Atlantic Council event Wednesday that Turkey's acquistion of the S-400 could present the U.S. military and NATO alliance with added technical risks. But he would not go as far to spell out what actions the Defense Department is considering or could consider later down the road — perhaps a sign that the Pentagon is waiting to see how this legislation shakes out. “We have a process to evaluate the risks to Western technology that that [procurement] would present. Our preference is that they do not acquire the S-400,” Goffus said. “Given that, they are a sovereign nation, and they are trying to take care of their defense needs,” he added. “What restrictions are placed on them and what Congress will eventually pass, I can't even speculate on it on this point.” By the time Congress passes legislation that could curb Anakara's F-35 ownership, the country will likely have already started building up its first squadron at Luke AFB. There, Turkish pilots and maintainers will train alongside U.S. ones, moving from academic courseware to live flights. NATO and U.S. Defense Department officials have warned Turkey that if it continues down the path of purchasing the S-400, it will not be able to plug it in with NATO technologies like the F-35. SASC, in its policy bill, echoed those concerns, saying that Turkey's purchase of Russian hardware would “degrade the general security of the NATO alliance [...] and degrade interoperability of the alliance.” After a meeting in Washington with U.S. Secretary of State Mike Pompeo earlier this month, Turkish Foreign Minister Mevlüt Çavuşoğlu expressed confidence that the United States would not only deliver the first F-35 to Turkey as planned, but that it would ultimately decide to continue F-35 sales to Turkey. “Turkey rejects threatening language from the U.S. on the issue, it is not constructive,” Çavuşoğlu said on June 4, according to a report from the Turkish newsgroup Anadolu Agency. Turkey plans to buy 100 F-35As. As a partner of the program, its domestic defense industry helps build the Joint Strike Fighter. Most notably, Turkish Aerospace Industries' serves as a manufacturer of the aircraft's center fuselage. It has also been chosen as a sustainment hub for the international F-35 community. https://www.defensenews.com/smr/nato-priorities/2018/06/13/despite-some-opposition-us-on-course-to-deliver-f-35s-to-turkey-on-june-21/
