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.

Army: Individual Soldiers Will One Day Control Swarms of Robots
By Matthew Cox Army robotics officials at Fort Benning, Georgia are trying to give individual soldiers the capability to control swarms of air and ground robotic systems for missions that often require large numbers of troops to accomplish. U.S. ground forces have used small ground robots and unmanned aerial systems for years, but only on a small scale, said Don Sando, director Capabilities Development and Integration Directorate at Benning. "To really get a large benefit from robotic systems, we have to break the one-soldier, one-robot link, because right now, you generally need one operator for one robotic system and that is effective and interesting, but when I can have dozens of robotic systems controlled by one soldier, now I have a significant advantage," Sando told a group of defense reporters today on a conference call. A single soldier could conduct reconnaissance over "large areas with fewer soldiers and many dozens of robotic systems," Sando said. "That starts to matter especially in conditions such as dense urban environment," Sando said. "The problem with urban environments is they consume soldiers ... limited lines of sight, tunnels, buildings -- all the things that just take manpower to overcome and control. "If we can expand that with robotic systems, both air and ground, then that has significant impact." The concept could be developed to enhance communications battlefields when networks are hampered by enemy activity as well as natural obstacles. "If our communications infrastructure is going to be contested, as we know it will, then how can I regenerate quickly and effectively in a given area with robotic systems, both air and ground, to create that network?" Sando said. CDID officials are developing a common controller that can control air and ground robots regardless of the model. "We are very close on that; we did some assessment last year. We proved the feasibility of about three different versions of controllers that can effectively control air and ground robotic systems," Sando said. "The advantage to that is a soldier only has to learn one system as opposed to every robot has its own unique controller." The goal is to make a decision on a common controller by late fiscal 2019, Sando said. But the problem is more than just choosing the right controller. "How do you train a soldier, and how do you train leaders to do that? Sando said. "It's one thing to have two hands on your rifle -- one soldier, one system. It's one thing to be a small unit leader, to have a few subordinate leaders under your control -- it's something else to have dozens of under your control." Organizations continue to come to Benning to "practice and develop algorithms to employ swarming unmanned aerial systems," Sando said. "The next thing beyond that is OK, how do I swarm ground robotic systems? How can I do that?" he said. "That is the thing we are least developed on and that's the thing we want to start trying to emphasize. "We are going to continue to develop that and test that and I think that poses the next really large return on investment as we expand robotic systems." https://www.military.com/defensetech/2018/06/27/army-individual-soldiers-will-one-day-control-swarms-robots.html
