    Army Reassures Anxious Industry Over Stryker Cannon Competition

    While at least two of six competitors have dropped out, the Army says it will still have plenty of 30mm turret options to choose from as it starts testing this fall. By SYDNEY J. FREEDBERG JR.on June 17, 2020 at 2:43 PM WASHINGTON: “This is a healthy competition,” the head of the Army Stryker program, Col. Bill Venable, reassured reporters. “My No. 1 mandate as the overall program manager was to protect the competition in this first phase.” Venable was allaying anxieties yesterday about the five-year-old effort to upgun the infantry transport version of the Stryker, an 8×8 armored vehicle that's become an Army workhorse worldwide since its controversial introduction in 2003. The wheeled Stryker was criticized for having lighter armor than the tracked M1 Abrams and M2 Bradley, although it's far better protected than Humvees. It often struggled over Afghan terrain. But its ability to move rapidly by road – with fewer stops for gas and maintenance than heavy armored vehicles – made it a favorite of US commanders from Iraq to Estonia. So, while overshadowed by high-tech prototypes from hypersonic missiles to high-speed helicopters to robotic tanks, the Army is doubling down on the proven Stryker in several ways: Two light infantry brigades are being converted into Stryker units, which increases the number of active-duty Stryker brigades from five to seven. (There are two more part-time units in the National Guard). Original manufacturer General Dynamics has a $2.4 billion contract to rebuild hundreds of existing Strykers as DVHA1 models with bigger engines, upgraded electronics, and mine-resistant “double-V” hulls. Leonardo DRS is developing a new anti-aircraft variant called IM-SHORAD. It is several months behind schedule due to COVID disruptions and software issues. And the Army is upgunning the basic infantry-carrier variant from an exposed 12.7mm (0.50 cal) machinegun, viable against infantry and unarmored trucks, to a turret-mounted Medium Caliber Weapon System (MCWS), a 30mm autocannon capable of killing light armored vehicles widely used by Russia General Dynamics urgently built 83 upgunned Strykers to reequip a single Europe-based brigade. Now the Army is holding an open competition for an official Program of Record (POR) to upgrade at least three more brigades with a more refined 30mm turret design – but we've heard some anxiety over whether any other vendor can really unseat the incumbent. Out of six companies awarded $150,000 design contracts last summer, Venable confirmed that at least two have dropped out. At the current — sensitive — stage of the competition, the program manager said after a quick consultation with his staff, he isn't allowed to disclose how many companies remain and how many have quit. But Venable did tell reporters that one vendor dropped out because it wasn't making adequate progress to meet the technical requirements, while another decided it didn't have a good enough chance of winning to justify the investment. While the Army gave competitors free Strykers and 30mm guns, they must provide their own turrets, electronics and other components to integrate the weapon and the vehicle into a functional fighting system, to be delivered to the Army for testing by August 10. “We're not funding their development,” Venable said, “[which is] in some cases millions of dollars they're going to invest.” While he won't second-guess any company's cost-benefit calculus, he's been working with all of them to try to keep them in the running, despite disruptions caused by the COVID-19 pandemic. “We have adjusted the evaluation strategy in order to maintain the competition as robust as we can,” he said. “This isn't the first competitive selection effort that I've run, and I will say we have more [viable competitors] than the incumbent, significantly more than the incumbent,” Venable told reporters. “We're going to present a variety of choices to the source selection authority to evaluate starting on 10 August.” Once the vehicles arrive in August, the Army will live-fire the 30 mm guns, check out the armor, and conduct a host of other tests. By January, Venable expects to have that data ready for the evaluation board, which aims to announce a winner by the end of April, 2021. After that, the winning company will start mass production, with the first vehicles scheduled for delivery to a Stryker unit in August or September 2022. That meets the Army's previously announced deadline to start fielding by the end of fiscal '22, Venable said. But the brigade will spend months more taking possession of the vehicles and training on them – a “Rubik's Cube” of logistics and scheduling, Venable said — before it's officially declared the “First Unit Equipped,” probably around March 2023. https://breakingdefense.com/2020/06/army-rebuffs-anxiety-over-stryker-cannon-competition

    Air Force’s Roper: 3D Printing ‘Going Like Gangbusters’

    "I've been so passionate about bringing in additive manufacturing, and small batch digital manufacturing, to help on aircraft parts availability," Air Force acquisition head Will Roper says. By THERESA HITCHENSon May 15, 2020 at 12:54 PM WASHINGTON: The Air and Space Forces are speeding efforts to adopt 3D printing as a major pillar of force sustainment, now making critical spare parts for weapon systems such as engine components for fighters and rockets. “Additive and advanced manufacturing [has] been going like gangbusters across the Air Force and Space Force — printing thousands of parts for airplanes,” Air Force acquisition head Will Roper said yesterday. “We're starting to print parts for satellites, including propulsion.” And today, the Air Force Rapid Sustainability Office (RSO) announced that it had reached a first milestone in its collaboration with General Electric to 3D print metal engine parts for aircraft — printing a metal sump pump for F-110 engines used by both F-15 and F-16 fighter jets. According to the announcement, the next phase of the program — Phase 1B , now being planned — will involve a family of parts on the TF34 engine, which has been in service for more than 40 years. “The collaborative effort between the US Air Force and GE shows great promise toward the adoption of metal 3D printed parts as an option to solve the US Air Force's current and future sustainment challenges,” Col. Benjamin Boehm, director of propulsion at the Air Force Life Cycle Management Center (AFLCMC) said in a press release. “This capability provides an alternate method to source parts for legacy propulsion systems throughout their life cycle, especially when faced with a diminishing supplier base or when infrequent demands or low volume orders are not attractive to traditional manufacturers.” GE originally approached the Air Force with the idea of a collaboration on 3D printed parts in 2019, and in April this year the service brought in the Defense Logistics Agency to help certify the GE-made parts for airworthiness. ALCMC, as we reported way back in September at the Air Force Association shindig, has also been pushing to get its depots around the country certified to print their own spare parts, beginning with those not critical to life and death. Air Force leaders see additive manufacturing as key to resolving the service's serious problems in maintaining aging aircraft and infrastructure and lowering costs. That said, the new 3D sump pump cover is an important piece of the engine. “Compared to other parts on the F110 engine, the sump cover might have lower functionality, but is incredibly important. It needs to be durable, form a seal and it needs to work for the entire engine to function – which is of course critical on a single engine aircraft like the F-16,” said James Bonar, engineering manager at GE Additive. The RSO-GE program is using a spiral development model, increasing the complexity and scale of parts printing with each phase. “In this program, complexity involves moving from simpler part identification, progressing to part and family of parts consolidation and eventually tackling complex components and systems, such as common core heat exchangers,” the press release said. Roper told reporters yesterday in a Zoom briefing that due to the COVID-19 pandemic, RSO has transformed its planned Advanced Manufacturing Olympics, originally planned to coincide with the now-postponed Tokyo Summer Olympics in late July, to a virtual event to be held November. It will allow 3D printing companies to show off their wares to potential service customers via a number of challenges, including a “printer shoot-off” and a “Box of Parts” challenge where manufacturers will compete to create a drone part without a blueprint. “We have been growing our network of small batch makers across the Air Force and Space Force,” Roper said. “I've been so passionate about bringing in additive manufacturing, and small batch digital manufacturing, to help on aircraft parts availability.” The COVID-19 crises has proven the “additive” value of tapping into a network of small manufacturers as the Air Force has scrambled to obtain personal protective equipment for airmen at far-flung bases, he explained. Because many large producers of items like face masks are overwhelmed, the service set up the “Air Force Rapid Advanced Manufacturing Portal,” or “AFRAMP,” as a method of finding and vetting small producers to meet service needs. “It's a portal where small batch manufacturers can make their capabilities known — show what they're able to produce — we vet them, and that then allows these small companies in aggregate to add up to large batch manufacturing,” Roper said. “We've already delivered over 11,000, different PPE devices to seven air bases that wouldn't have otherwise been able to get access for personal protective gear.” His hope is to expand that portal to other types of advanced manufacturing in the future. “I'm excited about scaling it up beyond just personal protective gear, and really having it be a one-stop-shop in the government for companies that can make things in small quantity — that can't mass produce, but can produce in mass if they're added up with a lot of their other sister companies.” https://breakingdefense.com/2020/05/air-forces-roper-3d-printing-going-like-gangbusters/

  • Greece Approves $14B 5Yr Modernization Plan, to Receive Rafales in Mid-2021

    Greece Approves $14B 5Yr Modernization Plan, to Receive Rafales in Mid-2021

    Greek lawmakers have approved a $14 billion five-year military modernization plan including purchase of Rafale jets, first of which it would receive around mid-2021. Athens is expected to sign the $3.04 billion deal for Rafale jets with French manufacturer Dassault Aviation later this month. It would cover delivery of 12 jets previously used by the French Air Force and 6 new ones. A dozen of the ordered fighters for the Hellenic Air Force would reportedly be upgraded to the latest F3R standard featuring Talios (TArgeting Long-range Identification Optronic System) new-generation laser designator pod. First of the ordered jets would arrive in the country in the first half of this year while the remaining will be delivered over the next two years. In September, a team from French MBDA reportedly went to Greece to discuss the supply of missiles and other munitions for the Rafales. The fighter can be armed with state-of-the-art missiles such as Meteor, Mica NG and SCALP. The introduction of the fully equipped Rafale would help the Greek air force to confront Turkey's air and naval force that is protecting its hydrocarbon prospecting vessels in the Eastern Mediterranean. Under its modernization plan, Greece wants to buy new helicopters, drones, frigates and upgrade its existing F-16 fighters. https://www.defenseworld.net/news/28779#.YAXP--hKiUk
