    Lockheed Martin’s SPY-7 Radar Is Going to Sea

    Posted on February 5, 2021 by Richard R. Burgess, Senior Editor ARLINGTON, Va. — Lockheed Martin's new SPY-7 radar will be sailing to sea on the ships of three navies as the company highlights the radar's capabilities for application to other navies, including the U.S. Navy. The SPY-7, which uses gallium nitride modules, initially was developed for the Navy's Air and Missile Defense Radar competition. It was adapted into the Long-Range Discrimination Radar (LRDR) procured by the U.S. Missile Defense Agency (MDA) as a sensor of the Ground-Based Midcourse Defense system. Being installed at Clear Air Force Station in Alaska, the LRDR is designed to discriminate between incoming warheads and decoys. The core building blocks [of the LRDR] are the same core building blocks in SPY-7,” said Jon P. Rambeau, vice president and general manager, Integrated Systems & Sensors, Lockheed Rotary and Mission Systems, during a Feb. 2 interview with Seapower. “[SPY-7] is a modular radar that allows us to build different configurations for both land-based and sea-based applications.” The SPY-7 has been selected by the Spanish navy to integrate it with the Aegis Combat System on its F110 frigates. The Canadian navy is procuring the radar to install it on its new Halifax-class surface combatant. Japan had selected the SPY-7 for its two planned Aegis Ashore ballistic-missile defense sites, but when the plans were cancelled in part out of concern for missile debris falling on populated areas, Japan shifted to a plan to deploy the SPY-7 on some future, unspecified sea-based BMD platform. Japan already has BMD capabilities in its Kongo-class guided-missile destroyers with Aegis systems using the SPY-1 radar. Japan, which already has placed an order for the SPY-7, “is going through a process now to determine exactly what that platform is going to look like,” Rambeau said. “We are pleased with the progress that the technology has made, and we're starting to see some uptake both here in the U.S. as well as abroad.” “SPY-7 is part of the Aegis common source library (CSL) and the interfaces are understood,” said Patrick W. McNally, director of communications for Integrated Warfare Systems & Sensors, in a statement to Seapower. “For Japan, we have completed the first of three releases which were recently demonstrated to MDA. Starting from the CSL, with over one million lines of code, Japan will be receiving the best of both Baseline 9 and 10 [Aegis software].” The U.S. Navy is considering backfitting some Flight IIA Arleigh Burke-class guided-missile destroyers with a radar more modern than the SPY-1, and Lockheed is keeping a watch on developments in the event the SPY-7 could complete in the program if it comes to pass. Rambeau said his company also “has some more affordable options available to upgrade some of the SPY-1 arrays to provide improved sensitivity and improved resistance to electronic attack and we think we can do that at a fraction of the cost of a wholesale replacement, so we've put forth a couple of options for upgrades to SPY-1 to both MDA and the Navy.” https://seapowermagazine.org/lockheed-martins-spy-7-radar-is-going-to-sea

    US drone maker senses a leg up in Europe

    By: Sebastian Sprenger PARIS — U.S. drone-maker General Atomics looks to get a foothold in the European market by touting the promise of smooth civilian-airspace integration of its aircraft by militaries there. The company considers the United Kingdom, with its Protector program of 20 or so planned aircraft, as the launch customer for the MQ-9B SkyGuardian, a successor to the Reaper. The medium-altitude, long-endurance (MALE) drones come with safety features that executives at this year's Paris Air Show said will enable a so-called military-type certification by the British authorities in the summer of 2023 — the final step toward allowing the drone to fly routinely alongside civilian air traffic. Belgium also has gained U.S. approval to buy four of the aircraft, complete with a detect-and-avoid suite that can alert the system whenever its flight path risks hitting another aircraft, according to a March 26 announcement by the Pentagon's Defense Security Cooperation Agency. That technology, along with a host of technologies for safe operations that have long been standard in manned aviation, is still considered something of a holy grail in the drone business. With unmanned aircraft expected to reach deeper into military and civilian life in the coming years, manufacturers on both sides of the Atlantic have been working feverishly to construct their products with requisite safety certifications in mind. General Atomics' sales pitch is perhaps indicative of an industry where the potential for airspace integration is now taking an equal seat to reconnaissance capabilities and combat punch. The American company can be expected to tread on manufacturers' toes in Europe, where vendors are shaping the evolving regulatory landscape of the European Union and member states to ensure compliance with all expected safety requirements. “We believe we should be there first,” General Atomics President David Alexander told reporters at a briefing during the air show. Being first with a certified drone, he noted, would also open vast potential of the commercial market. But questions remain. Most importantly, issue experts said, it is unclear if the European authorities will honor whatever progress in safety certifications the MQ-9B has made in the eyes of the U.S. Federal Aviation Administration. Company officials told Defense News they try to keep their fingers at the pulse of the relevant policymaking processes on the continent, putting them at the same tables as suppliers in the European industry, like Airbus, Hensoldt or Leonardo. The American firm recently worked with the Royal Netherlands Aerospace Center, or NLR, to simulate a SkyGuardian flying in European airspace. “During the first simulations performed in May, we subjected air traffic controllers to many contingency procedures ranging from engine failure to loss-of-link between the pilot and the remotely piloted aircraft,” Emmanuel Sunil, an NLR project manager, said in a June 18 statement by the research center. “The results indicate that the new procedures that we are developing will make it possible for MALE RPA to fly safely and efficiently in civil European airspace along with other manned air traffic.” https://www.defensenews.com/digital-show-dailies/paris-air-show/2019/06/21/us-drone-maker-senses-a-leg-up-in-europe/

    Les dépenses militaires s’engagent aussi pour la croissance

    Les budgets militaires de nombreux pays augmentent, dans le contexte récent du conflit en Ukraine mais également depuis quelques années, non sans conséquences économiques. L'idée est communément admise que dépenser plus pour l'armement nuit à la croissance, en privant de moyens un gouvernement qui souhaiterait investir dans un autre secteur de son économie. Le lien n'est pourtant pas direct. La preuve a été faite que l'augmentation des budgets militaires procure de substantiels bénéfices économiques. Israël qui dépense 6% de son PIB dans sa Défense est aussi le pays de l'OCDE dont la croissance est la plus dynamique, les dépenses militaires pouvant doper la croissance gr'ce à leur impact sur l'emploi. La Défense a aussi un impact positif en constituant une forme non déclarée de politique industrielle : une étude sur les pays de l'OCDE, menée par Enrico Moretti, de l'université de Californie à Berkeley, montre qu'une augmentation de 10% des dépenses publiques en Recherche et Développement entraine une augmentation de 5% de la Recherche et Développement privée. Néanmoins, si ces investissements peuvent être des moteurs de la croissance, paix et stabilité restent deux éléments fondamentaux d'une économie prospère. Challenges du 28 avril
