  Saab delivers virtual Gripen E program update

  by Chris Thatcher The Saab Gripen E test program has surpassed 300 flight hours and the company is preparing to deliver production aircraft to the Swedish Air Force in 2020. “We are proceeding according to plan and are delivering according to our customers' expectations,” Eddy de la Motte, the head of Saab's Gripen E/F business unit, told webinar viewers during a briefing on Mar. 26. The annual update on the Gripen program was moved to an online forum in response to the coronavirus pandemic. Although Sweden has for now adopted a notably different approach to addressing the spread of COVID-19 than its neighbours – most businesses remain open – defence and aerospace journalists and other interested attendees were confined to virtual participation. “Saab is not one of those companies that is feeling immediate consequences because of the situation given a large order backlog and the business model that we use,” said Ellen Molin, head of Business Area Support Services. “We are doing everything we can to work on development and production.” The Gripen E is among three fighter jets contending to replace the Royal Canadian Air Force fleet of CF-188 Hornets. The others are the Lockheed Martin F-35A Lightning II and the Block III Boeing FA-18E/F Super Hornet. The Gripen E is the only one not yet in service. The briefing was an opportunity for Saab to highlight the progress of the flight test program and forthcoming deliveries to the first customers, Sweden and Brazil. The test program now includes six aircraft and will be expanding to two sites this year involving test pilots from Saab, the Swedish defence materiel administration, and the Swedish Air Force. The accelerated test and verification program will be “more efficient,” said de la Motte. “We are now shifting focus to more testing on the tactical systems and the sensors.” Saab had high expectations for the Gripen E's enhanced fused sensor suite and decision-support capabilities before flight testing began, he said. But the Active Electronically-Scanned Array (AESA) radar, passive infrared search and track (IRST) sensor, tailored datalink and multi-function electronic warfare (EW) system “are preforming better than expected.” Testing has also included an electronic jammer pod to complement the internal active EW system, flights with the MBDA Meteor beyond-visual-range air-to-air missile, and firing of the short-range IRIS-T air-to-air missile. The first production aircraft rolled off the line in Linköping, Sweden earlier this year, and the second and third will be delivered to Sweden later in 2020. Among other milestones, Saab turned over the first test aircraft to the Brazilian Air Force in August 2019. Its arrival in Brazil is scheduled for the end of 2020. Brazil has ordered 36 jets, 28 in the single-seat E variant and eight in the two-seat F model. In advance of the Brazilian flight test program and the launch of a Gripen flight test centre in Brazil, Saab has transferred aircraft intellectual property and knowledge to hundreds of Brazilian technicians, test engineers and pilots at its production facility in Linköping. Furthermore, the Gripen Design and Development Centre in Brazil has cut the first metal on the F-model two seat variant, to be delivered in 2023. Saab is also hoping to expand its customer base as the Gripen E enters service. In February, the company demonstrated two of its test aircraft at Pirkkala Air Base in southern Finland as part of the HX Challenge, the first stage of a capability assessment of five aircraft vying to replace the Finnish Air Force fleet of F/A-18 C and D Hornets. The Gripen is up against the Eurofighter Typhoon, Dassault Rafale, Lockheed Martin F-35A and Boeing F/A-18 Super Hornet. The two aircraft were demonstrated alongside a Saab GlobalEye airborne early warning and control platform, a multi-role air, maritime and ground surveillance system based on the Bombardier Global 6000/6500 jet. As part of a package with Finland, Saab is proposing to transfer intellectual property to operate maintenance, repair and overhaul facilities, spares production, final assembly and a development and sustainment centre. “We fully understand the needs of national security and the ability to control critical technology,” said de la Motte. A similar offer is likely to be part of Saab's pitch to Canada when the request for proposals closes on June 30. In March, the company announced a “Gripen for Canada Team” that includes IMP Aerospace & Defence, CAE, Peraton Canada and GE Aviation. De la Motte said the proposal for 88 Gripen E jets would include “high skilled jobs” as well as aircraft and systems built by Canadians. Both de la Motte and Molin emphasized the “smart and cost-efficient support concept inherent in the aircraft design” that now includes the ability to 3D print spare parts for battle damage repair in a forward hangar to allow grounded aircraft to return to a main operating base. That efficiency was underscored by Col Torgny Fälthammar, head of the Gripen program for the Air Staff of the Swedish Air Force (SAF). A former Saab 37 Viggen and Gripen C fighter pilot, he noted the SAF “operates in a domain where the time to react is sometimes very short – the aircraft and systems we face have a very high velocity.” Since Sweden can't field superior numbers, “we have to strive for the best balance between technology, competence and tactics, and having the relevant numbers... [and] we believe we have found that in the Gripen system.” The Gripen E will introduce “high tech, state-of-the-art systems,” he added. But “being a small country, we always have to think about money and affordability.” https://www.skiesmag.com/news/saab-delivers-virtual-gripen-e-program-update

  Here’s what the Space Development Agency wants from its first 10 satellites

  Nathan Strout The Space Development Agency is seeking proposals for its first batch of satellites, which will make up its initial transport layer — an on-orbit mesh network that will connect space-based sensors with terrestrial shooters. According to the May 1 solicitation, SDA is looking to award two contracts to build a total of 20 small satellites, which will comprise Tranche 0 of the National Security Space Architecture, a proliferated, low-Earth orbit constellation that will fulfill a multitude of military needs, including tracking hypersonic weapons; providing alternative position, navigation and timing data; delivering beyond-line-of-sight targeting; and more. Ultimately, the agency envisions a constellation made up of hundreds of interconnected satellites. Ten of those Tranche 0 satellites will form the agency's initial transport layer. The spiral development approach The agency is taking a spiral development approach to its National Security Space Architecture. Tranche 0 will be a testing and training segment that will demonstrate the integration of the architecture with other war-fighting efforts and inform future SDA developments. Tranche 0 is anticipated to be on orbit in the fourth quarter of fiscal 2022, with the SDA adding new tranches of satellites every two years, increasing the constellation's size and capabilities. Launch services will be acquired through the Orbital Services Program 4 contract or follow-on contracts. The philosophy behind the spiral approach is that the two-year cycles allow the agency to rapidly put new capabilities on orbit in response to evolving threats. Instead of waiting years for the perfect satellite system, the agency wants to push technologies that are currently ready into orbit as soon as possible, giving war fighters increased capabilities in the near term. With Tranche 0, the SDA wants to achieve periodic, regional, low-latency data connectivity. With Tranche 1, which will add 150 satellites to the constellation, the agency plans to provide persistent regional connectivity. Building a mesh network The National Security Space Architecture will be made up of several layers serving different functions. Tranche 0 will establish the transport layer, a space-based mesh network that will be able to pass data from one satellite to the next. The mesh network will operate as part of the Integrated Broadcast System, the Defense Department's standard network for transmitting tactical and strategic intelligence and targeting data. The key technology that will enable the transport layer are optical inter-satellite cross links, providing approximately 1 Gbps connections between the satellites. Each Transport Layer satellite will have four such cross links — forward, behind, right and left — which will allow them to pass data on to the nearest or next-nearest transport layer satellite operating in the same orbital plane. The satellites will also be capable of cross-plane cross links, meaning they will be able to connect to non-transport layer satellites operating above or below them. Assuming that they also have optical inter-satellite cross links, these non-transport layer satellites would then be able to pass data through the transport layer's mesh network to another satellite or even to a terrestrial shooter. For example, it could work like this: A space-based sensor collects imagery that it wants to pass to a ground-based system, but it is not within range of any ground station. No problem. The sensor would pass on that imagery to a transport layer satellite via an cross-plane optical cross link. The data would then bounce from transport layer satellite to transport layer satellite until it arrives above its destination, where it would then be downlinked to an optical ground terminal or distributed to the appropriate weapons system via the Link 16 tactical data network. In theory, this would allow shooters to receive space-based sensor data in near-real time. Since the SDA plans to continue building on the transport layer in subsequent tranches across multiple vendors, the optical inter-satellite cross links will need to be designed with interoperability in mind. The SDA also wants radio frequency cross links as a backup to the optical cross links. Tranche 0 will include 10 transport layer satellites — three of which will include Link 16 payloads. During an April industry day, SDA Director Derek Tournear said this initial, space-based mesh network will form the space network component to the Defense Department's Joint All-Domain Command and Control enterprise, or JADC2. “The transport layer, which is what the draft [request for proposals] and the industry day was talking about today, is going to be the unifying effort across the department. That is going to be what we use for low-latency [communications] to be able to pull these networks together, and that, in essence, is going to be the main unifying truss for the JADC2 and that effort moving forward. That is going to be the space network that is utilized for that,” Tournear explained. The agency has six goals for its Tranche 0 transport layer: Demonstrate low-latency data transport to the war fighter over the optical cross link mesh network. Demonstrate the ability to deliver data from an external, space-based sensor to the war fighter via the transport layer. Demonstrate a limited battle management C3 functionality. Transfer Integrated Broadcast System data across the mesh network to the war fighter. Store, relay and transmit Link 16 data over the network in near real time. Operate a common timing reference independent of GPS. According to the request for proposals, the SDA plans to award a contract Aug 10, with delivery expected by July 31, 2022. Responses to the solicitation are due June 1. https://www.c4isrnet.com/battlefield-tech/space/2020/05/05/heres-what-the-space-development-agency-wants-from-its-first-10-satellites/
