U.S. Air Force Upgrading C-17 and C-130H Avionics As Supplier Base for Legacy Systems Falls

The U.S. Air Force is undertaking a number of avionics upgrades for Boeing [BA] C-17 and Lockheed Martin [LMT] C-130H transport aircraft, as the supplier base for legacy avionics systems falls, according to the Air Force Life Cycle Management Center (AFLCMC) at Wright-Patterson Air Force Base, Ohio.

“Diminishing Manufacturing Sources Material Shortfalls (DMSMS) are driving avionics-related upgrades,” AFLCMC wrote in email responses to questions from Defense Daily.

The AFLCMC C-17 program office (AFLCMC/WLM) at Robins Air Force Base, Ga., is undertaking a nearly $286 million C-17 Replacement Head-Up Display (RHUD) program with Elbit Systems of America to replace the 1980s-era C-17 HUD by the defunct U.K.-based GEC Avionics, whose former business is now part of Leonardo.

The Elbit Systems RHUD for the C-17 has a Projector Unit (PU) and a Computer Unit (CU) that “displays symbols and real-world conformal imagery over an increased field of view to include the capability to display threat warnings and quadrant, supports two independently selectable video inputs for autonomous landing growth requirements, provides aircraft Electronic Bore-sighting capability, [and] provides improved reliability with a Mean Time between Failure (MTBF) of 3,000 operating hours,” according to AFLCMC/WLM.

A GEC Avionics brochure issued in 1987 for the C-17 HUD said that the HUD has an MTBF of 7,000 operating hours, but, “based on current performance, the actual [HUD] MTBF is between 1,600 and 1,800 hours (lower than predicted),” according to AFLCMC/WLM. “The Statement of Requirements for the Replacement Head Up Display (RHUD) development delivery order requested 3,000 hours MTBF at maturity.”

In addition, for the Boeing C-17 aircraft, the Air Force is undertaking “satellite communications upgrades for increased coverage and throughput speeds along with mitigation of obsolescence issues due to satellite service dates” and “upgrades of legacy aircraft avionics to capabilities of current commercial production aircraft, large area displays, [and] improved weather radars,” AFLCMC/WLM said.

Under a $209 million Beyond Line of Sight (BLOS) program for the C-17, AFLCMC is replacing the aircraft's L-Band Aero-I and Aero-H antennas, providing air traffic control data link capabilities, replacing the Collins Aerospace [UTX] ARC-210 Gen 3 radios with ARC-210 Gen 6 radios, and replacing KYV-5 cryptography with next-gen KYV-5M, AFLCMC/WLM said.

Last July, the Air Force picked Honeywell [HON] to install its JetWave Ka-band fuselage-mounted antenna (MCS-8100 and tail-mounted antenna (MCS-8000) on 70 C-17s to provide real-time weather, video conferencing, large file transfer, encryption capabilities, in-flight briefings, intelligence surveillance reconnaissance video and secure communications in all areas, including over water and remote areas. The C-17 BLOS program will “enable dynamic re-tasking and command and control support of MAF [Mobility Air Forces] aircraft,” the Air Force said. JetWave uses Inmarsat‘s Global Xpress Ka-band service to provide worldwide connectivity with up to 50 Mbps of bandwidth to defense customers, according to Honeywell Aerospace.

In December, AFLCMC completed Block 21 upgrades for all 275 C-17s, operated by the Air Force and allied nations, according to AFLCMC/WLM. The upgrades included hardware and software for Automatic Dependent Surveillance-Broadcast Out (ADS-B Out) required by the U.S. Federal Aviation Administration and aviation authorities in Europe for planes operating in controlled airspace.

“In addition to ADS-B Out, Block 21 included an Identification of Friend or Foe (IFF) modification and other communication/navigation capability software updates,” AFLCMC said. “These additional modifications significantly improve the aircraft's flight management systems.”

For the C-130H, the Air Force last June awarded L3Harris [LHX] a nearly $500 million contract for avionics upgrades to 176 Air Force Reserve and Air National Guard aircraft under the C-130H Avionics Modernization Program (AMP).

L3Harris has chosen Collins Aerospace to provide its commercial off-the-shelf Flight2 integrated avionics system. Collins Aerospace said that is providing seven multifunctional displays (MFDs), three control display units (CDUs), and a new digital autopilot that will replace more than 100 analog instruments in C-130H cockpits.

The AFLCMC C-130 program office (AFLCMC/WLN) at Robins Air Force Base said that the C-130H AMP increments 1 and 2 include “compliance with latest commercial and military Position, Navigation, and Timing (PNT) standards, a new flight management system, new commercial and military GPS receivers, improved [RNP] Required Navigation Performance], compliance with VHF 8.33KHz channel spacing requirements and ADS-B Out and Mode S Enhanced Surveillance (EHS) requirements, military satcom voice and data via the Lockheed Martin Mobile User Objective System (MUOS), improved UHF anti-jam capability via the Collins Aerospace Second generation Anti-jam Tactical UHF Radio for NATO (SATURN), Real-Time Information into the Cockpit (RTIC), Link 16, [and a] digital map.”

The C-130H upgrades also include a terrain awareness and warning system (TAWS), according to AFLCMC/WLN. RTIC is to allow the C-130H aircraft to share data with other systems over multiple data link networks.

    Turkish firm develops AI-powered software for drone swarms

    Burak Ege Bekdil ANKARA, Turkey — A privately owned Turkish company says it has developed an artificial intelligence-based software for swarm drones. MilSOFT announced Nov. 19 it developed the software after four years of research, and the the technology could be used in both fixed- and rotary-wing drone platforms. A government aerospace official said swarm drones would be used in Turkey's future unmanned aerial combat concept due to their low hardware costs and stealth technology. “These drones could be ideal in asymmetrical warfare. They are quick, cost-effective and easy to operate,” the official said. “Most importantly, they are assets designed to minimize human loss in asymmetrical warfare.” The Turkish military has been operating a big fleet of tactical and armed drones primarily in combat against Kurdish militants in Turkey's southeast provinces but also in cross-border operations in northern Syria and Iraq. Turkish drones have also been used in Libya's civil war and, most recently, in conflict between Armenia and Azerbaijan. Many countries have yet to try drone swarm technology in a simulated, controlled environment. Turkey is among those that have the technology and the ability to test it in the field during operations. Turkey's top procurement office, the Presidency for Defense Industries, launched its Swarm UAV Technology Development and Demonstration program with a view to develop algorithms and software for the use of unmanned platforms with a swarm capability. The program is also meant to involve micro-scale companies as well as small and medium-sized enterprises. MilSOFT has specialized in software solutions since 1998, and it is one of the participants of the government-run program. It has been offering products to the Turkish military for tasks including identifying detection by automatic moving target technology using AI, and machine-learning techniques with image-processing algorithms. The company said with the integration of intelligence and image evaluation products, drone swarms can be updated with additional capabilities such as reconnaissance, detection, recognition, search and rescue, and vehicle tracking. MilSOFT's software-based solution will allow drone swarms to be launched from aerial, land and naval platforms, and the images they obtain will enter a central command system. In the meantime, the drone flocks will transfer images between different military units with a relay function. AI technology can help catch elements that cannot be caught by the human eye and enable multiple attack capabilities by arming vehicles in operation. MilSOFT's AI-based software is also expected to enable swarm drones to perform frontal attacks on command from helicopters and provide operational support to other friendly platforms. The drones can reportedly operate autonomously from the beginning to the end of a mission, and can be instantly monitored and controlled via intelligence applications. The UAVs have a flight time of more than half an hour and a payload capacity of 1 kilogram (2.2 pounds). The vehicles work with landing gear that can land on rough terrain. While five UAVs are currently used in a herd in the field, this number can reach up to 25 in a controlled environment. MilSOFT aims to make a drone swarm of 50 operational vehicles. Communication between the drones is also provided by MilSOFT's own technology. Vehicles can communicate with each other from up to 500 meters. There is also a 10-kilometer network solution for data transfers. MilSOFT plans to integrate its technology for underwater and surface platforms as well as land vehicles. https://www.c4isrnet.com/unmanned/2020/11/24/turkish-firm-develops-ai-powered-software-for-drone-swarms/

    Un rapport du Sénat appelle à sauver la BITD

    Un rapport du Sénat appelle le gouvernement à maintenir un effort de défense substantiel sous peine de voir disparaître des pans de la base industrielle et technologique de défense, la BITD. Celle-ci « joue dans les cinq ans qui viennent sa survie », estiment les auteurs, deux sénateurs de la commission des affaires étrangères et de la défense, Pascal Allizard (Les Républicains) et Michel Boutant (PS). Le nouveau gouvernement devrait annoncer après l'été un plan de relance. « Il est fondamental que ce plan comporte un volet spécifique pour la BITD, soulignent Pascal Allizard et Michel Boutant. Les entreprises de la BITD qui disparaîtraient faute de relance ne seront pas remplacées ». La Tribune du 14 juillet 2020

    How the Air Force plans to find ‘defense unicorns’

    By: Nathan Strout Dozens of space companies descended on San Francisco, California Nov. 5 for a unique opportunity: the chance to walk away with a same day contract with the Air Force. Opportunities like that don't happen every day for smaller businesses and start-ups, but at the first Air Force Space Pitch Days, 30 companies presented ideas to Air Force acquisition leaders who were authorized to hand out contracts on the spot. At the end of the first day, the Air Force had issued $9 million in contracts to 12 companies, with more companies slated to pitch their ideas on day two. While the “Shark Tank”-inspired event may seem like a gimmick, it's part of an effort by the Air Force to engage with businesses that don't have the resources or know-how to compete with large, established defense contractors for military projects, but may have innovative solutions that the military needs. “This is part of a broader vision we have to return Air Force to its innovation roots,” said Will Roper, the Air Force's assistant secretary for acquisition, technology and logistics during a Nov. 6 media availability. “We want to be where innovation is happening. We want to partner with commercial companies that have aspirations to make the world a better place with their technologies, but make it clear that there is a way to work with the Air Force to achieve that objective ... Innovation is going to be its own competitive domain, almost a battlefield. And we've got to win the innovation battle." Not every company that presents at pitch days will succeed, but through events like this Roper hopes to give smaller businesses a chance and hopefully discover what he calls defense unicorns, non-traditional companies that have innovative solutions but lack the resources to bring them to market and connect to military customers. “How do we do that, where we can start making defense unicorns?” said Roper. “That must happen if we're going to compete against countries like China long term. If the unicorns in defense are only started by billionaires, then we'll ultimately lose. We need companies that have ambitions without that huge billionaire backing up front to find a way to stardom through us.” With pitch days, the Air Force is using Small Business Innovative Research awards to reach these companies early in the design process and then foster them through to production in three phases. “By the time we get to Space Pitch Day next year, we should have the three-fold approach continually in cycle. Phase 1, get you in the door, very small contract, help you understand your Air Force customer, get you mentored to come to a pitch event like this. Phase 2 you're pitching to the customer and the war fighter, show your product actually has a match to our mission, get you on a bigger contract where you can prototype, develop and test. Then Phase 3, you're productizing. Your getting your product ready to sell to us, ready to use by us, and hopefully that's on a path to selling to the world,” said Roper. “What I expect will happen in an ad hoc way is that a lot of our investment in these companies will be matched by private investors,” he added. The Air Force first introduced the pitch day concept at an event in March, where they doled out $8.75 million between 51 companies. Since then the Air Force has held several other events, with individual days devoted to fields such as hypersonic weapons or intelligence, surveillance and reconnaissance systems. “Whether it's data analytics or some sort of software sensing methodology; whether its hardware, advanced rocket designs or better rocket fuel; whether its small sats or new ground sensors–those kind of innovations are the things that we are entertaining this week and will continue to entertain,” said Lt. Gen. John ‘JT' Thompson, commander of the Air Force's Space and Missile Systems Center. “Maybe not all of them, but many of them could become game changers in our efforts to maintain the United States Air Force's superiority in space.” https://www.c4isrnet.com/battlefield-tech/space/2019/11/07/how-the-air-force-plans-to-find-defense-unicorns/
