    Chile approved for $634M worth of F-16 upgrades

    By: Aaron Mehta Updated at 6:35 PM EST to include information on the number of planes being upgraded. WASHINGTON — The U.S. State Department has cleared Chile to purchase modernization upgrades for its F-16 fleet, with a potential $634 million price tag. Chile currently operates 44 F-16s. That includes 10 Block 50 models purchased in the early 2000s, as well as 36 older models bought second-hand from the Netherlands. Reports that Chile would look to upgrade their existing F-16 fleet first emerged in 2017, but final details had not been made public. Analysts have also speculated that Chile may look to buy a small number of new F-16s to supplement its fleet. The upgrades included in this potential sale include 19 Joint Helmet-Mounted Cueing Systems (JHMCS); six inert MK-82 (500LB) general purpose bomb bodies; two MXU-650KB Air Foil Groups (AFG); 44 LN-260 Embedded GPS/INS (EGI) and 49 Multifunctional Information Distribution System Joint Tactical Radios (MIDS JTRS). Also included are avionics equipment and software upgrades, new radios, upgraded IFF transponders, secure communications equipment and other parts. The upgrades are expected to go across the 44 plane fleet. “The proposed sale will improve Chile's capability to meet current and future threats by modernizing its F-16 fleet, which will allow Chile to maintain sovereignty and homeland defense, increase interoperability with the United States and other partners, and deter potential adversaries,” per a statement on the website of the Defense Security Cooperation Agency. Lockheed Martin, which produces the F-16, will be the prime contractor on the deal, should it go through. All DSCA announcements must be cleared by Congress. At that point negotiations begin. Quantities and dollar values often change in the final agreement. Although this is the first FMS case approved for Chile since the start of fiscal 2017, the F-16 has proven to be a reliable sales vehicle for Lockheed abroad, with 14 F-16 related FMS requests cleared by DSCA during this time period. https://www.defensenews.com/global/the-americas/2020/07/23/chile-okd-for-f-16-upgrades/

  • Virtual reality training — for pilots, maintainers and more — expands in 2020

    Virtual reality training — for pilots, maintainers and more — expands in 2020

    By: Stephen Losey One of the top priorities of Lt. Gen. Brad Webb, the newly minted head of Air Education and Training Command, will be expanding the Air Force's experiment with virtual reality training. So far, the Air Force has had success with Pilot Training Next, which uses VR, biometrics and artificial intelligence to better teach aspiring pilots how to fly. Webb is eyeing similar technologies, under the name Learning Next, to improve other forms of technical training. This could include teaching airmen how to maintain aircraft, fly remotely piloted aircraft or perform other technical tasks. These programs allow students' education to proceed more at their own pace, since they are based on competency and are not tied to a timetable, Wright said. A student who already has the fundamentals down can skip the basics and go right to what he or she needs to learn. AETC is now in the process of broadening Pilot Training Next, which has been a demonstration, to the next phase of wider experimentation, Webb said. He and Maj. Gen. Craig Wills, commander of the 19th Air Force, are working on plans to expand Pilot Training Next. By next summer, Webb wants to have set up Pilot Training Next elements at several squadrons, though it wouldn't be across all undergraduate pilot training bases. A few classes after that, Webb expects, Pilot Training Next will be expanded to all UPT bases. The Pilot Training Next expansion will likely be done methodically, at one base first, Webb said, though he would not say which base AETC is looking at. “What has happened in our last couple of years with Pilot Training Next has been an explosion, out of the box, of innovation,” Webb said. “Make no mistake, the Air Force wants this inculcated as fast as we can go,” he said. AETC is already in the “nascent stages” of testing VR and other technology-enhanced training for maintenance and other technical training as part of Learning Next, Webb said. Maintenance Next is a particular priority and is happening on an experimental basis at Kelly Field at Joint Base San Antonio-Lackland in Texas, he said, and using VR for RPA training is also proceeding. As the VR pilot training shows, such programs can accelerate in a hurry, he said. Ethics Webb also wants to cultivate an “environment of excellence, professionalism, ethics and character development” during his time at AETC. Webb, who was previously commander of Air Force Special Operations Command, pointed to the ethical clouds that have fallen over parts of the special operations community in recent years. For example, the Navy relieved the entire senior leadership team of SEAL Team 7 earlier this month over what it described as leadership failures that resulted in a breakdown of good order and discipline while deployed. AFSOC took a hard look at itself, Webb said, to make sure it doesn't allow similar lapses to fester. “For a leader, you can never ... talk about core values enough,” Webb said. “If I had to look myself in the mirror from my last command, I can tell you my team knew our mission and vision of priorities backwards and forwards.” But while airmen at AFSOC understood Air Force core values, he acknowledged he didn't always articulate those values in his everyday “walk-around, talk-around” encounters. That can create problems if leaders assume airmen already know about the core values, he said. When a unit starts to feel the pressure from high operations tempos and a lack of resources, Webb said, that “get-'er-done” mentality can lead to bad decisions if airmen don't have a firm foundation of the Air Force core values. “If you don't have a firm foundation, you can go to a dark place with that ... ‘find a way to yes' mentality,” Webb said. “We've got to always talk about professionalism and ethics, and also always talk about our core values. That will be a capstone” of his time at AETC. Webb said he plans to continue with AETC's recent improvements in how special warfare airmen are recruited and trained, which included standing up the new Special Warfare Training Wing and the special warfare-focused 330th Recruiting Squadron. More work needs to be done to “normalize” and fine-tune those units, and more firmly fold them into AETC's everyday culture, he said. https://www.airforcetimes.com/news/your-air-force/2019/09/16/virtual-reality-training-for-pilots-maintainers-and-more-expands-in-2020/

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

    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.
