  The Air Force will need terminals that work with more than GPS

  By: Nathan Strout Congress wants the Air Force to develop a prototype receiver capable of using navigation signals provided by other countries, which could increase the resilience of the military's position, navigation and timing equipment. The primary source of the military's PNT data is the Global Positioning System, a satellite system operated by the Air Force. But with adversaries developing GPS jamming technology and anti-satellite weapons that could potentially knock out one or more of those satellites, Congress wants a receiver capable of utilizing other global navigation satellite systems. The annual defense policy bill, which was passed by both chambers of the legislature this week, calls on the Air Force to develop a prototype receiver capable of utilizing multiple global navigation satellite systems in addition to GPS, such as the European Union's Galileo and Japan's QZSS satellites. The belief is that if the GPS signal is degraded or denied, war fighters could switch to one of those other systems to get the PNT data they need. According to Brian Weeden, director of program planning at the Secure World Foundation, the provision represents an evolution from the Department of Defense's stance on foreign GNSS signals from 15 years ago. “When Galileo was first announced, there was a big debate within the Pentagon about whether to cooperate with the Europeans or try and kill it,” Weeden wrote to C4ISRNET in a Dec. 18 email. “The big driver there was that the Europeans were going to park their protected signal on top of M-code and then sell their service as being unjammable by the Americans (assuming that the US couldn't jam the protected Galileo signal without also interfering with M-Code).” Efforts to kill Galileo ultimately died, Weeden noted, although the EU did move their protected GNSS signal off of M-Code, a more secure military version of the GPS signal that is in development. That concession and the subsequent development of GPS jamming capabilities by Russia and China has changed the thinking on Galileo and other GNSS signals. “It seems the Pentagon has decided that leveraging Galileo will make their PNT capabilities more robust as Russia or China would need to jam both of the separate military signals,” said Weeden. “There's some engineering and technical wizardry still to be worked out to create a good multi-GNSS receiver but it's doable.” Congress wants the Air Force to report on the benefits and risks of each potential GNSS signal, and it fences 90 percent of the funding for the Military GPS User Equipment Program until lawmakers receive that report. https://www.c4isrnet.com/battlefield-tech/space/2019/12/19/the-air-force-will-need-terminals-that-work-with-more-than-gps

  Army taps industry for Gray Eagle payloads for joint ops against high-end threats

  By: Jen Judson WASHINGTON — The Army wants its Joint All Domain Operations (JADO) Gray Eagles to have synthetic aperture radars, moving target indicators, electronic intelligence and communications intelligence capability as well as air-launched effects and radar warning receivers, according to a new market survey. Now, the Army wants help from industry with those payloads for its Gray Eagle unmanned aircraft systems. Specifically, the service is looking for systems that are capable of helping with joint operations across all warfighting domains against high-end threats from adversaries such as China and Russia, according to a solicitation published Dec. 2 to a government contracting website. The service's Aerial Enhanced Radar, Optics and Sensors (AEROS) product manager wants industry to “identify potential existing sources capable of providing Aerial Intelligence, Surveillance and Reconnaissance (AISR) payloads for the MQ-1C Gray Eagle Unmanned Aircraft System platform that meet the JADO environment,” the solicitation posted to Beta.Sam.Gov states. These Gray Eagles payloads must be capable of increased ranges and resolutions “to support target location and Long-Range Precision Fires (LRPF) without the use of traditional line of site visual equipment to include Electro Optical, Infrared (EO/IR) and Full Motion Video (FMV) required for today's Counter Insurgency (COIN) mission,” the request for information stresses. Traditional COIN payloads won't hold up against peer and near-peer adversaries, the Army noted, as they will “employ anti-access, area denial strategies, posing a significant challenge to the current AISR fleet,” the solicitation states. Gray Eagles must survive against an “Integrated Air Defense System (IADS)-rich environment,” the request notes. This means the Gray Eagle would fly “racetrack patterns tangential to the IADS threat at 80 km distance” and would be capable of deploying Air-Launched Effects (ALE) forward into enemy territory to detect, identify and locate targets and take out or disrupt threats, according to the request. The Gray Eagle would also have payloads that could detect IADS threats, locate them and transfer the information to other sensor systems capable of recognizing targets and coordinating long-range fires, the solicitation describes. The Army is conducting the survey ahead of a Gray Eagle sensor payload JADO demonstration that could potentially take place in fiscal 2022 where systems will be “quantitatively compared” to find the highest performing and best value payloads based on technology readiness and production cost, the request lays out. The solicitation for more advanced payloads for Gray Eagle comes at a time when the Army is trying to design a complex architecture of helicopters and unmanned aircraft systems that would be part of tight-knit kill chain to include space and ground assets underpinned by an advanced network. The Army experimented with the kill chain to include air assets at Project Convergence at Yuma Proving Ground, Arizona, over the summer. The effort brings together future weapons and capabilities envisioned for a 2030s battlefield against near-peer adversaries such as Russia and China. It includes using a machine learning and artificial intelligence-enabled battle management system that is in development. Gray Eagle represented a Future Attack Reconnaissance Aircraft (FARA) surrogate. During the first mission thread at Project Convergence, which focused on the penetration phase laid out in the Army's Multidomain Operations warfighting concept, Gray Eagles and ALE partnered with space-based assets, APNT, and LRPF capabilities to locate, then degrade and destroy enemy assets modeled after the Russian Pantsir air defense systems and other weapons. The ALE pushed ingested data forward through the network to get it to the right shooters, whether that would be an Extended Range Cannon Artillery (ERCA) system on the ground or a Gray Eagle or another ALE. The Army was able to extend the ALE capability out to almost 62 kilometers, which would provide deep standoff for manned aircraft like FARA. The ALEs performed both the reconnaissance, surveillance and targeting acquisition mission and worked as a mesh network to extend the battlefield. Two ALEs were truck launched and four were air launched. Also during the final shot of the entire campaign at Project Convergence, a soldier on the ground took control of a LRPF munition surrogate (a Hellfire missile in this case) on a Gray Eagle and fired on the target. The Gray Eagle at Convergence was able to route around and avoid threat weapon systems and also fired a live Dynetics-made GBU-69 small glide munition. Previewing the future, the Army also used an open system architecture that was flexible enough for payloads and capabilities to be swapped in out of its Gray Eagles without having to rely on the original equipment manufacturer to do it. https://www.defensenews.com/land/2020/12/02/army-taps-industry-for-gray-eagle-payloads-for-joint-ops-against-high-end-threats/

  Australia, Naval Group conclude sub negotiations

  By: Nigel Pittaway MELBOURNE, Australia – Australian Defence Minister Christopher Pyne confirmed that the Australian government has finally concluded negotiations for the formal signing of a strategic partnering agreement for 12 large conventionally-powered attack submarines from Naval Group. Australia is acquiring the vessels under its $50 billion (U.S. $36.12 billion) Project Sea 1000 (Future Submarine) to replace its existing fleet of six Collins Submarines from the early 2030s. The subs will be the ‘Attack' class with the lead vessel named HMAS Attack. They will be fabricated in Australia to a design previously known as the Shortfin Barracuda 1A. Recent local media reports have suggested that negotiations between the parties had stalled, placing the government's timeline for the Collins replacement in jeopardy, but Pyne said on Thursday the program was still on track. “There's been a lot of ill-informed mythmaking around the negotiations but I'm very happy to say today the negotiations are complete,” Pyne said during sod-turning event at the site of the Future Submarine Construction Yard at Osborne in South Australia. “The strategic planning agreement will be signed in February next year and we can continue to get on with the submarine project, which has been under the design and mobilization contract for the last two years.” Declining to provide details of the intricacies of the agreement due to their commercial nature, Pyne said the negotiations were officially concluded at an Australian Government National Security Committee meeting in Melbourne on Dec. 10. “Suffice to say the Australian government's interests, the Australian taxpayer's interests, have been taken care of,” he said. “Naval Group Australia will deliver 12 regionally-superior submarines on time and on budget.” Australia's Chief of Navy, Vice Adm. Mark Noonan, also denied reports of an emerging capability gap between the retirement of the first Collins submarines and the Attack boats entering service, which some analysts have suggested might require a ‘Plan B' to be formulated. “I don't believe that's the case,” he told reporters. “We've got a very solid plan to ensure that there is no gap in our nation's submarine capability, and there is a very advanced plan that will see a number of our current Collins class submarines going through a life of type extension program, which will ensure that capability gap doesn't exist.” https://www.defensenews.com/global/asia-pacific/2018/12/14/australia-naval-group-conclude-sub-negotiations/
