  The U.S. Air Force's New F-15EX Fighters Could Double As Jamming Planes

  Fitted with the new Eagle Passive Active Warning Survivability System, or EPAWWS, the twin-engine, two-seat F-15EX in theory could project a protective bubble of radar-muddling noise around itself and nearby warplanes.

  U.S. Army Pursues Alternatives To GPS

  Jen DiMascio In its attempt to ensure that soldiers have access to GPS-like information, even when access to those U.S. Air Force satellites may be compromised, the U.S. Army is in the process of fielding an alternative system on certain ground vehicles. The Army began fielding the first iteration of the Mounted Assured Positioning, Navigation and Timing System (MAPS), an anti-jam GPS alternative, on General Dynamics Stryker vehicles in the 2nd Cavalry Regiment this year. The service will field 300 such systems to the 2nd Cav this year, according to Willie Nelson, director of the Army's Assured Positioning, Navigation and Timing Cross Functional Team. Thousands are supposed to be installed into vehicles in U.S. European Command by 2028. On Oct. 15, the U.S. Army announced it had chosen Collins Aerospace to provide a next-generation MAPS for manned ground vehicles. Collins will make MAPS Gen II, systems that will be evaluated for a year and potentially be fielded to 8,000 additional vehicles. The Collins Aerospace system combines the NavHub-100 navigation system and Digital GPS Anti-jam Receiver-100. The system adds a military code capability and modernized signal tracking to improve reliability and integrity, Collins says. The MAPS program is part of the U.S. Army's focus on modernization. But it is also a response to a request from commanders in Europe and Korea, according to Gen. John Murray, commander of Army Futures Command. The Army maintains that its effort to look for alternate means of positioning, navigation and timing is aligned with the U.S. Air Force's plans for GPS satellites. Asked about the threat from Russia, Brig Gen. Robert Collins, program executive officer for intelligence, electronic warfare and sensors, said the U.S. needs confidence not just in the ability of U.S. assets to withstand jamming attacks but to be able to fend off spoofing efforts as well. “The electromagnetic spectrum is becoming contested and people are operating in that space,” Collins said. “We recognize that our traditional GPS today is not where we need it to be from a survivability perspective. So we have looked at how to make it more hardened.” Along with those efforts, the Army has also planned an industry day for Oct. 29-31, as it seeks new inertial measurement unit and timing technologies. https://aviationweek.com/defense/us-army-pursues-alternatives-gps

  The Army wants new tools to sense, disrupt and protect signals

  By: Mark Pomerleau The Army will be hosting members of industry in 2019 to discuss opportunities on signals intelligence and electronic warfare, according to a December 2018 notice. The Signals Intelligence/Electronic Warfare (SIGINT/EW) Future Opportunities and Terrestrial Layer System (TLS) Industry Day will be hosted Jan. 23 at Aberdeen Proving Ground, Maryland. The Army has charted a path forward that includes integrating signals intelligence and electronic warfare systems into a single tool for greater synergy between the two disciplines. One of the first systems the Army is building on this front is the Terrestrial Layer System, an integrated EW and signals intelligence system that will provide a much-needed jamming capability to formations. The Army is taking a multitiered approach to TLS, leveraging assessments, exercises and even deployments of quick-reaction capabilities to inform how the service will move forward on prototyping and providing much-needed capabilities, such as this one, to units. Officials have noted that this approach differs from acquisition processes of the past. “We hope to go faster, but with the authorities granted by Congress ... we think this rapid prototyping using the buy, try, decide method is going to be great for this rapid acquisition process,” said Col. Jennifer McAfee, director of the Training and Doctrine Command's capabilities manager for terrestrial and identity at the Intelligence Center of Excellence. “Are we going to field this next week? Not necessarily, but we're talking fielding to the force in the next two to three years, not seven to 10 years.” Industry's role will be to help provide prototypes that will reduce the risk of flaws in the final solution. https://www.c4isrnet.com/electronic-warfare/2018/12/21/the-army-wants-new-tools-to-sense-disrupt-and-protect-signals
