  Three of Russia’s European neighbors push for joint armored vehicle

  By: Sebastian Sprenger COLOGNE, Germany — Estonia, Latvia and Finland have signed a technical agreement for a jointly developed armored vehicle, with Estonia touting the plans as a means to jump-start the defense industry and maintain its security posture following the global coronavirus crisis. The new pact enables Estonia to continue its participation in the tri-national effort to scope out requirements for the “potential” procurement of a fleet of armored vehicles featuring common components, the Estonian Defence Ministry wrote in a statement. "We have to keep in mind that our primary goal here is to develop a platform that meets the requirements of Estonian Defence Forces with a favorable price,” Kristikan Prikk, permanent secretary at the ministry, was quoted as saying in the statement. “We see big potential in this project, especially as we are involved already in the development phase, which is the best way to secure that eventually we will have equipment that meets our needs.” The technical arrangement, inked on Monday, follows a letter of intent signed in December that laid out the broader parameters for the joint project. Estonia aims to replace its 140 Pasi armored vehicles, made by Finland's Patria and first fielded in the 1980s. The fleet is expected to reach the end of its useful life in 2024, according to the Defence Ministry. Initial results toward developing a prototype for a new vehicle are planned for this year, according to officials. “It is important for us that international defense cooperation, which has a very clear economic dimension, continues,” Prikk said. “In the current crisis, it is also crucial that we continue to strengthen our defense capability and, if possible, lay the foundation for creating new jobs or maintaining existing ones in the Estonian defense industry sector.” Estonia shares a border with Russia, as do the other two program members Finland and Latvia. Those countries have been nervous about the possibility of Russian military adventurism along its borders with the West. And with the COVID-19 pandemic wreaking havoc on national economies and testing international alliances, some issue experts believe there could be more reason to worry when the dust settles. https://www.defensenews.com/global/europe/2020/04/07/three-of-russias-european-neighbors-push-for-joint-armored-vehicle/

  The Air Force tested its Advanced Battle Management System. Here’s what worked, and what didn’t.

  By: Valerie Insinna WASHINGTON — The first field test of the U.S. Air Force's experimental Advanced Battle Management System in December was a success, with about 26 out of 28 capabilities showing some semblance of functionality during a recent exercise, the service's acquisition chief said Tuesday. But the service will seek to be more ambitious during a second demonstration in April, which will focus on space and bring in elements from U.S. Space Command and U.S. Strategic Command, said Will Roper, the Air Force's assistant secretary for acquisition, technology and logistics. "I am thrilled to say that 26 out of 28 things work. That is too high of a success rate at this point in time, but I'll take it. We should be taking more risk than that,” he told reporters during a roundtable. The three-day test took place at Eglin Air Force Base, Florida, and involved a potential cruise missile attack on the United States simulated by QF-16 drones. Through the exercise, Air Force F-22 jets, Air Force and Navy F-35 fighters, the Navy destroyer Thomas Hudner, an Army unit equipped with the High Mobility Artillery Rocket System, as well as special operators shared data in real time in ways the services cannot currently do in an operational environment. What will ABMS eventually look like? That's still a mystery, even to the Air Force, which wants to test different solutions for connecting platforms, crunching data and sending it to other assets with the goal of eventually fielding what works and abandoning what doesn't. “We gave the team the goals of: Pull what you can together in three and a half months to see how far we can stretch, how quickly we could achieve something,” said Air Force chief architect Preston Dunlap, who manages the ABMS effort. “We were quite happy actually, even with 10 percent solutions.” Here's a rundown of some notable successes so far, as well as major failures: The F-35 and F-22 were able to stealthily exchange data. Despite the two jets having advanced “sensor fusion” capabilities, the Air Force's two most advanced fighters can't really talk to each other. The F-35 uses the Multifunction Advanced Data Link, or MADL, to securely share sensitive information with other F-35s, while the F-22 has its own data link, the Intra-Flight Data Link, or IFDL. Even using a non-stealthy connection to share information has its limitations: While the F-35 can both transmit and receive data via the Link 16, which meets NATO standards, the F-22 currently can only receive data. However, the first ABMS test showed hopeful signs for fifth-generation fighter communication. The demonstration involved radio systems — built by F-35 prime contractor Lockheed Martin as well as Northrop Grumman, which manufactures key structures and mission systems for the aircraft, including MADL, Dunlap said. The demo also included Honeywell-made antennas built to speak across both MADL and IFDL, he added. Those systems were integrated onto a ground based rig that “look[ed] like a big piece of hardware with radios on it,” according to Roper. Then, the F-35 and F-22 flew over the system, exchanging data by bouncing it back-and-forth from the ground-based radios, Dunlap said. He noted that the test verified that existing technology can be used to overcome three obstacles: translating the F-35's MADL to the F-22's IFDL; moving data across the different frequencies; and securing the communication. "It was really herculean,” Dunlap said. "[The contractors] were excited by the speed of the acquisition team to get the ball going." During the next ABMS demo in April, the Air Force plans to stretch the capability by putting the translation system inside the unmanned Kratos XQ-58 Valkyrie for flight-based testing. “I also challenged the team to expand the amount of information translated between the different platforms so they can take advantage of new information on the displays,” Dunlap said. An AC-130 gunship connected with SpaceX's Starlink constellation. Although Dunlap did not provide much detail on this element of the exercise, he confirmed that the AC-130 was able to pass data through the constellation of small, high-bandwidth commercial internet satellites. The Air Force has shown interest in connecting its platforms to commercial broadband satellites through its Global Lightning experiment. A demonstration with Starlink and the KC-135 tanker aircraft is in the works, and the service also plans to evaluate equipment from Iridium, OneWeb and L3Harris. The Air Force created a cloud-based application for command and control. Typically, the service performs command and control from air operations centers — physical buildings where analysts sit in front of computers with specialized software that provides data from multiple assets, Dunlap said. Changes to software don't necessarily happen automatically, and they may require assistance from information technology experts. In the ABMS exercise, the Air Force demonstrated a cloud-based battle management and situational awareness application for the first time. It used a “CloudOne” system to host data up to the secret level, which will be a formative system underlying ABMS, Dunlap said. Both Amazon and Microsoft are involved in standing up the CloudOne technology, but Roper said the Air Force could use the Joint Enterprise Defense Infrastructure contract vehicle for CloudOne if JEDI winner Microsoft provides better rates. The robot dogs were a swing and a miss. U.S. Special Operations Command brought the robots that are capable of augmenting surveillance operations to the ABMS field test, but operators couldn't figure out how to connect them with the other platforms involved in the exercise. “We had some robot dogs — apparently those exist — that can go and do patrol. We were never able to patch their feeds in,” Roper said. There's hope for cybernetic canines becoming part of ABMS in the future though. Roper added that the ABMS team would be welcome to try to integrate the robots in future exercises. https://www.c4isrnet.com/air/2020/01/22/the-us-air-force-tested-its-advanced-battle-management-system-heres-what-worked-and-what-didnt/

  A Modern Solution To Improved Performance, Cost, Use For The Venerable Chinook

  It's the dream of military acquisition in 2020: A new system that drops into place in a current piece of hardware, provides improved performance, easier maintenance, and builds on a legacy of more than 12 million battle-proven hours of operation. It's the T55 714C, Honeywell Aerospace's new variant of the venerable T55 turboshaft engine used on American helicopters and fixed wing aircraft since 1955. The engine's starring role, however, is aboard Boeing's CH-47A and MH-47 rotorcraft, known as the Chinook. The heavy-lift Chinook that has served the Army consistently, as well as international customers, for more than 60 years features two counter-rotating rotors that eliminate the need for an antitorque vertical rotor. The unique design requiring two T55 engines per aircraft allows all the T55's power to be used for lift and thrust and enable perhaps the toughest helicopter pilot maneuver known—the pinnacle landing. In the years since the T55 and Chinook entered service in 1962, Honeywell has delivered more than 6,000 engines, with 2,500 engines in service today supporting 950 aircraft operating in 20 countries. Dave Marinick, Honeywell's President of Engines and Power Systems, says throughout all these years the company has invested in the engine, from its original 1,600 shp capability to today as the T55 produces 4,800 shp to power the Chinook to a maximum speed 196 mph. But now, with Future Vertical Lift and its high-speed rotorcraft on the horizon, Honeywell looked again at what the Army needed to power the Chinook to fill the heavy lift role as the Future Armed Reconnaissance Aircraft and Future Long-Range Assault Aircraft go into service. "Looking back at the multi-decade history, characterized by a close relationship with the Army and an understanding of how the aircraft is used—how the army flies the Chinook, how they maintain the Chinook—we have been able to focus on what is important to our customer," Marinick adds. The Charlie variant of the T55 fits the bill, according to Marinick. It maintains the current engine architecture, while offering 20% more power, nearly 10% improved performance at high and hot altitudes and using 9% less fuel. It includes a modern full authority digital engine control with health monitoring. "We designed in a cost-effective way to increase power to 6,000 shp, and we have a roadmap to increase that up to 7,500 shp," Marinick says. "And while saving gas is one thing, we also are extending the range with the new engine, allowing the pilot to fly or loiter longer, an important option for the operators using this aircraft—whether for military missions, fire suppression or disaster relief." In addition to its performance improvements, the T55 714C features a new compressor and improved reliability and lifecycle. The accessory section has also been redesigned based on feedback from Army customers. In the past, maintainers had to pull the engine entirely to access the accessory section on the number 2 engine. The redesign shifts the accessory section to the top of the engine, providing easier and saving hundreds of man hours to make a switch. There are no changes to the engine mounts, making the T55 714C a drop-in replacement. It can be installed as a full-up new engine or as a kit that is introduced during overhaul. "In this concept, we are turning a maintenance event into much more—a Chinook leaving with new engines, without requiring a block upgrade. We're delivering major performance improvements, without tearing up the aircraft," Marinick says. The engine's tooling, logistics and training remain the same, further reducing the time required to introduce a much-improved engine. The new engine comes with another major change. The U.S. Army has completed a product verification audit to provide approval for Honeywell to open a state-of-the-art T55 Repair and Overhaul Center of Excellence near the company's Phoenix, Arizona headquarters. Marinick says the new facility will increase throughput by two to three times the previous capacity for CH-47 Chinook helicopter fleets. The move also establishes a larger pool of highly trained technicians who will work alongside the engineering team to streamline feedback and help to inform future upgrades. The company has also launched an initiative to ensure on-time delivery of materials from suppliers to support the expanded capacity. "Future Vertical Lift is upon us," Marinick says, "We think of the Charlie as an affordable, responsible upgrade and service designed to keep the Chinook at optimum performance and readiness in a realistic way, through 2060." Honeywell's upgraded T55 Charlie engine is expected to be ready for flight test at the end of 2022. For more Information about the T55, click here.
