WASHINGTON: Army Futures Command is drafting a formal requirement for a military exoskeleton and will seek feedback from manufacturers at a November industry day. The Army's top priority, officials told me: rapidly prototyping a system that helps the wearer “move faster, travel further, and carry heavier loads” – without breaking down in the heat of battle.
“Reliability is a huge issue that needs to be resolved,” said Ted Maciuba, deputy director of robotic requirements for Futures Command.
Now, don't expect a full-body bulletproof suit that can fly and access huge databases out of science fiction. “We are not going after the Starship Troopers/Iron Man system right off the bat,” said Rich Cofer, a former soldier who's now the Army's lead “capabilities developer” on the exoskeleton project. “We're not going to jump right in and expect Tony Stark... Expectation management is key.”
(That's a stark contrast to Special Operations Command's highly publicized TALOS program, which explicitly compared itself to Iron Man but produced nothing of the kind).
So instead of Iron Man, think Iron Leg. In a “soldier touchpoint” last December at Fort Drum, NY, Army soldiers from more than two dozen Military Occupational Specialties — ranging from infantry to supply — tried out various types of “lower-body exoskeletons,” including the Lockheed Martin ONYX that our own Paul McLeary tries out in this video. In essence, these are motorized knee braces and other wearable reinforcements for the legs that lighten the load on overburdened soldiers as they march for hours with heavy packs, manhandle artillery shells and such. The goal isn't to give the wearer superpowers, but to reduce fatigue and risk of injury.
During the Fort Drum trials, “there were significant increases in the effectiveness of soldiers,” Maciuba told me. “The soldiers were able to do more with the exoskeleton than they could without.”
That said, “we learned [that] there needs to be enough reliability engineered into our systems so that there is a very high probability they will not fail in use,” Maciuba continued. “It's one thing to be wearing a boot whose sole flips off. You can always take some 100-mile-an-hour tape and tape that back on your foot. It's another thing to be wearing an exoskeleton” that requires specialized training and tools to fix. So reliability will be a high priority when the Army speaks to potential vendors in mid-November.
By that point, Maciuba & co. expect to have a draft Abbreviated Capabilities Development Document for industry to review and offer comment on. (Army Futures Command officially gave them the go-ahead to write the ACDD on Aug. 14th; the exoskeleton project falls under the command's Soldier Lethality team, with input from PEO-Soldier acquisition officials, Natick Soldier Systems Center researchers, and capability managers for infantry, armored, and Stryker units). While unclassified, the document will be considered sensitive and only released to qualified contractors.
While the ACDD is formally considered a requirements document, Maciuba told me, it's not going to set rigid technical specs as would a traditional Army requirement. The technology is advancing way too fast to get that detailed at this early stage. Instead, he said, it will outline “desirable characteristics” but leave industry plenty of leeway to innovate on specific ways to achieve them – and the Army is open to revising those desires based on what industry says is actually achievable.
“We want industry to grade our work,” Maciuba said. The industry day – which will be held online unless there's some miraculous breakthrough with COVID-19 – will include both a general session open to all contractors and one-on-one meetings with specific contractors so they can discuss their technology without competitors listening. Afterwards, Maciuba, Cofer, & co. will compile the feedback from all the companies, revise the ACDD, and send it to Army leaders for approval.
The final Abbreviated Capabilities Development Document should be out by the end of 2021, Cofer estimated. The next step? Use a streamlined acquisition process known as Section 804, intended to field a working prototype within five years – that is, Maciuba cautioned, if the Army can find the funding.

Forbes II/U.S. Navy Stabilizing the production system and securing a funded, long-term upgrade plan are now the main objectives for Pratt & Whitney's F135 propulsion system for the Lockheed Martin F-35. Although first delivered for ground--testing 17 years ago, the F135 remains a lifeline in Pratt's combat aircraft engines portfolio for new-development funding. The U.S. military engines market is entering an era of transition with great uncertainty for the timing of the next major combat aircraft program. Enhancement Package replaces “Growth Option” New F-35 propulsion road map due in six months The transition era begins with the likely pending delivery of Pratt's most secretive development project. In 2016, the U.S. Air Force named Pratt as one of seven major suppliers for the Northrop Grumman B-21 bomber. The Air Force also has set the first flight of the B-21 for around December 2021. That timing means Pratt is likely to have delivered the first engine for ground-testing. At some point within the next year, Pratt should be planning to deliver the first flight-worthy engine to Northrop's final assembly line in Palmdale, California, to support the Air Force's first B-21 flight schedule. As the bomber engine development project winds down, the propulsion system for the next fighter aircraft continues to be developed, but without a clear schedule for transitioning to an operational system. The Air Force Research Laboratory's Adaptive Engine Transition Program (AETP) is sponsoring a competition to develop an adaptive engine that can modulate the airflow into and around the core to improve fuel efficiency and increase range. The AETP competition is between Pratt's XA101 and GE's XA100 designs, with the first engines set to be delivered for ground-testing by the end of this year or early next year. As 45,000-lb.-thrust-class engines, the first AETP designs are optimized for repowering the single-engine F-35, but the F-35 Joint Program Office (JPO) has established no requirement to replace the F135 for at least another five years. A follow-on effort within the AETP is developing a similar engine for a next-generation fighter, but neither the Air Force nor the Navy have committed to a schedule for transitioning the technology into an aircraft-development program. That leaves Pratt's F135 as the only feasible application for inserting new propulsion technology for a decade more. After spending the last decade focused on completing development of the F-35 and upgrading the software, electronics and mission systems, the JPO is developing a road map to improve the propulsion system through 2035. As the road map is being developed, program officials also are seeking to stabilize the engine production system. Pratt delivered about 600 F135s to Lockheed through the end of last year, including 150—or about 25%—in 2019 alone. The JPO signed a $7.3 billion contract with Pratt last year to deliver another 509 engines in 2020-22, or about 170 a year. Although Pratt exceeded the delivery goal in 2019 by three engines, each shipment came an average of 10-15 days behind the schedule in the contract. The fan, low-pressure turbine and nozzle hardware drove the delivery delays, according to the Defense Department's latest annual Selected Acquisition Report on the F-35. Lockheed's production schedule allows more than two weeks before the engine is needed for the final assembly line, so Pratt's late deliveries did not hold up the overall F-35 schedule, says Matthew Bromberg, president of Pratt's Military Engines business. F135 deliveries finally caught up to the contract delivery dates in the first quarter of this year, but the supply chain and productivity disruptions caused by the COVID-19 pandemic have set the program back. About five engines scheduled for delivery in the second quarter fell behind the contractual delivery date, Bromberg says. The pressure will grow as a loaded delivery schedule in the second half of the year adds pressure on deliveries, but Pratt's supply chain managers expect to be back within the contract dates in the first quarter of next year, he says. The F-35 program's political nature also has caused program disruptions. The Defense Department's expulsion of Turkey from the F-35 program last year also banished the country's supply chain, which contributed 188 parts to the F135. In particular, Alp Aviation produces the Stage 2, 3, 4 and 5 integrally bladed rotors (IBR) for the F135. As of early July, about 128 parts now made in Turkey are ready to transition to other suppliers, of which about 80% are based in the U.S., according to Bromberg. The new suppliers should be requalified to produce those parts in the first quarter of 2021 and ready to meet production rate targets for Lot 15 aircraft, which will begin deliveries in 2023. “The overriding objective was to move with speed and diligence along the transition plan and ensure we are ready to be fully out of Turkey by about Lot 15,” Bromberg explains. “And we are on track for that.” As Pratt transfers suppliers, the company also has to manage the effect on potential upgrade options. Alp Aviation, for example, had announced a research and development program to convert the finished titanium IBRs to a more resilient nickel material. For several years, Pratt has sought to improve the performance of the F135 above the baseline level. In 2017, the company unveiled the Growth Option 1.0 upgrade, which is aimed at delivering modular improvements that would lead to a 5% or 6% fuel-burn improvement and a 6-10% increase in thrust across the flight envelope. The Marine Corps, in particular, was seeking additional thrust to increase payload mass for a vertical landing, but the proposed package did not go far enough to attract the JPO's interest. “It missed the mark because we didn't focus our technologies on power and thermal management,” Bromberg says. A year later, Pratt unveiled the Growth Option 2.0. In addition to providing more thrust at less fuel burn, the new package offered to generate more electrical power to support planned advances in the aircraft's electronics and sensors, with the ability to manage the additional heat without compromising the F-35's signature in the infrared spectrum. Last fall, the JPO's propulsion management office teamed up with the Advanced Design Group at Naval Air Systems Command to analyze how planned F-35 mission systems upgrades will increase the load on the engine's thrust levels and power generation and thermal management capacity. In May, the JPO commissioned studies by Lockheed and Pratt to inform a 15-year technology-insertion road map for the propulsion system. The road map is due later this year or in early 2021, with the goal of informing the spending plan submitted with the Pentagon's fiscal 2023 budget request. As the studies continue, a name change to Pratt's upgrade proposals reveals a fundamental shift in philosophy. Pratt's earlier “Growth Option” terminology is gone. The proposals are now called Engine Enhancement Packages (EEP). The goal of the rebranding is to show the upgrades no longer are optional for F-35 customers. “As the engine provider and the [sustainment] provider, I'm very interested in keeping everything common,” Bromberg says. “The idea behind the Engine Enhancement Packages is they will migrate into the engines or upgrade over time. We don't have to do them all at once. The [digital engine controls] will understand which configuration. That allows us again to be seamless in production, where I would presumably cut over entirely, but also to upgrade fleets at regularly scheduled maintenance visits.” Pratt has divided the capabilities from Growth Options 1 and 2 into a series of EEPs, with new capabilities packaged in increments of two years from 2025 to 2029. “If you go all the way to the right, you get all the benefits of Growth Option 2, plus some that we've been able to create,” Bromberg says. “But if you need less than that and you're shorter on time or money, then you can take a subset of it.” Meanwhile, the Air Force continues to fund AETP development as a potential F135 replacement. As the propulsion road map is finalized, the JPO will decide whether Pratt's F135 upgrade proposals support the requirement or if a new engine core is needed to support the F-35's thrust and power-generation needs over the long term. Previously, Bromberg questioned the business case for reengining the F-35 by pointing out that a split fleet of F135- and AETP-powered jets erodes commonality and increases sustainment costs. Bromberg also noted it is not clear the third-stream technology required for the AETP can be accommodated within the roughly 4-ft.-dia. engine bay of the F-35B. Now Bromberg says he is willing to support the JPO's decision if the road map determines a reengining is necessary. “If the road map indicates that they need significantly more out of the engine than the Engine Enhancement Packages can provide, we would be the first to say an AETP motor would be required,” Bromberg says. “But we think a lot of the AETP technologies will make those Engines Enhancement Packages viable.” https://aviationweek.com/ad-week/f-35-propulsion-upgrade-moves-forward-despite-uncertainty

By: Pierre Tran Communications & Systèmes, a specialist in mission critical systems, launched July 2 a capital increase to raise €10.2 million (U.S. $11.9 million) and finance an announced expansion in European defense and security. The rights issue is intended to raise finance for a mergers and acquisition plan, dubbed Plan Ambition 2021, and follows the approval June 26 by a CS shareholders meeting for the acquisition of Novidy's, a cybersecurity company. “I am rather delighted. This is a step forward,” CS CEO Eric Blanc-Garin told Fifth Domain July 2. “The capital increase will enlarge the shareholder base, bring in more institutional investors and improve the stock liquidity.” The main aim is to fund the company's expansion by mergers and acquisition. “We have targets; we are in active discussion,” he said, when asked if CS has a list of companies in its M&A plan. An issue of new stock is intended to raise €10.2 million, which could rise to €11.5 million if the offer meets demand from the stock market. The new stock will be priced at €5.90 per share, a 22.2 percent discount on the closing price June 28. Current shareholders are offered two new shares for every 25 shares held. A core shareholder, Sopra Steria Group, has committed to subscribe to the stock issue. Sopra Steria holds 10.36 percent of CS and has pledged to inject €1.1 million into the company by exercising its preferential rights. “This capital increase will allow CS to have the means necessary to realize other operations of external growth with priority in Europe in the growth sectors of defense and civil security, space and cybersecurity,” the company said in a statement. Current shareholders will have a preferential right for subscribing to the stock issue. The shareholders meeting approved the capital increase, which had been announced as a second step in the Plan Ambition 2010 and follows the agreed offer for Novidy's. The acquisition of Novidy's boosts CS's annual sales in cybersecurity to €40 million, with the sector accounting for 20 percent of the company's total revenue, the company said in a June 26 statement. “We are delighted that our shareholders have unanimously approved this acquisition, which allows CS to mark a new stage in its development,” Blanc-Garin said in the statement. “This is the first significant step in our strategic plan, Ambition 2021.” https://www.fifthdomain.com/industry/2018/07/02/french-firm-makes-moves-to-fund-cybersecurity-expansion/
