    Entreprises stratégiques : l’État doit établir des mécanismes de protection, alertent Eric Trappier et Jean-Charles Larsonneur

    «Il revient aux États de définir les mécanismes de protection des entreprises stratégiques de défense face à des investissements de fonds réputés agressifs», a souligné mardi Éric Trappier, président du GIFAS et PDG de Dassault Aviation. «Aux États-Unis, lorsque des fonds étrangers veulent entrer au capital d'une entreprise américaine ou en prendre le contrôle, le projet est étudié par le CFIUS (Comité sur les Investissements Etrangers aux États-Unis) qui vérifie que cet investissement ne menace pas les intérêts stratégiques américains», a-t-il expliqué. «L'Europe pourrait se doter d'un tel outil. Pour cela, il faut regarder les aspects juridiques, les règles de concurrence car nos entreprises travaillent sur des marchés ouverts, et «détourer» ce qu'est une entreprise stratégique». Jean-Charles Larsonneur, député LREM spécialiste du sujet, interrogé par Le Figaro, met également en garde contre les risques de rachat d'entreprises stratégiques françaises, notamment de la part de la Chine et des Etats-Unis. «On parle de résilience et de souveraineté, alors il faudrait que l'Europe investisse dans sa défense», conseille-t-il.

    Change of plans: Seoul decides to start from scratch with helo competition

    By: Jeff Jeong SEOUL — It looked like Italy's aerospace group Leonardo was going to be an easy winner for South Korea's second batch of anti-submarine helicopters. The procurement program would seek 12 more AW-159 “Wildcat” helicopters, with no other competitors for the $840 million program. But the Defense Acquisition Program Administration, or DAPA, threw a curveball, deciding to accept a U.S. proposal for alternate option and to begin the competitive bidding process from the scratch. The plan for the maritime operational helicopter, or MOH, was originally to sign a direct commercial deal with a foreign helicopter maker, with three bidders — Leonardo, Lockheed Martin and NH Industries — showing interest. The two latter contenders failed to submit their proposals by the Oct. 31 deadline, leaving Leonardo seemingly as the only remaining bidder. According to sources from DAPA, however, the U.S. government in November sent a letter of price and availability of Lockheed Martin's MH-60R Seahawk, causing South Korea's arms procurement officials o rethink the acquisition approach. “We've decided to consider the U.S. FMS option,” DAPA spokesman Park Jung-eun told Defense News. “We're going to weigh in on both options of commercial and FMS contracts.” As dictated by acquisition regulation, two successive failed biddings mean that the agency can make a private contract with a sole bidder, but that's not mandatory. The agency is expected to issue a renewed request for proposals as early as March, according to DAPA officials. Leonardo would be a direct buy, while the Sikorsky bid would be a foreign military sale. Leonardo said in a statement that it would still pursue the South Korean naval helicopter program “in a fair and transparent manner.” A Leonardo spokesman said the AW-159 is optimized for the Korean theater of operations, pointing to an active electronically scanned array (AESA) radar for detecting North Korea's coastal weapon system and a missile firing range that is more than three times longer than Seahawk. “We do not really know about the details of the U.S. Navy's latest proposal,” a Lockheed Martin communications official said, declining to elaborate. “After an RFP is issued, we could be able to discuss with the service.” Pundits here expressed different reactions to the renewed MOH bidding process. Shin In-kyun, head of Korea Defense Network, a Seoul-based private defense think tank, said it's a better opportunity to acquire state-of-the-art naval helicopters with better performances. “The Seahawk is estimated to be more expensive by 20 to 30 percent than the Wildcat, but the former has performances about two times better than the latter,” said Shin. “The unit price of the MH-60R could be lowered through the FMS, as the U.S. and Indian Navies are also said to be procuring more than 40 MH-60Rs.” Shin Jong-woo, a senior analyst at the Korea Defense & Security Forum, said an FMS deal may not guarantee economic benefit for South Korea. “You give up offset programs should an FMS deal be made,” he said. “I'm not really sure how much the unit cost of the MH-60R could be lowered. If lowered, we may have to lose some optional functions of the helicopter.” Moreover, a possible MH-60R selection will bring more work to change the designs of warships, he added. “The Navy's existing warships, including the KDX-III Aegis destroyer, are not able to accommodate the MH-60R, so it's inevitable to change the design should the American helicopter be chosen.” The South Korean Navy currently operates eight AW-159s acquired under a 2012 deal. The helicopters fly missions aboard KDX-series destroyers and Incheon-class guided-missile frigates. The service plans to commission at least 12 more new frigates fitted with a flight deck and a hangar that can accommodate one Lynx helicopter. https://www.defensenews.com/2019/01/23/change-of-plans-seoul-decides-to-start-from-scratch-with-helo-competition

  • These 4 technologies are big problems for US military space

    These 4 technologies are big problems for US military space

    By: Nathan Strout A recent report highlights the fact that the commercial space sector is an increasingly important part of the military's efforts in space, but there are places where industry falls short. The national security space arena is a niche market, characterized by low production runs paired with a need for high-quality products. That combination makes it a difficult area for the commercial sector. While national security space increasingly relies on industry to provide components for space vehicles, the fact remains that in some key areas there are no domestic suppliers for critical technologies, leaving the United States dependent on foreign suppliers. Here are four such technologies singled out in a recent report on the United States military's industrial base: Solar cells According to the report, the commercial sector is not investing in the research and development needed to improve solar cells, which are used to power satellites. Businesses have maxed out the capacity for triple-junction solar cells, but do not appear capable of pushing forward to four- or five-junction solar cell technology. The Pentagon also wants solar cells that are able to withstand more radiation for longer than current products on the market. Improving solar cells to get the same or more power out of even slightly smaller panels could have a major impact when it comes to launching a satellite into space, meaning that reducing solar panel size is highly valuable. Tube amplifiers Starting in the 1990s, the domestic supplier market share for traveling-wave tube amplifiers — electronic devices used to amplify radio frequency signals to high power — dropped from 50 percent to just 12 percent. While that market has shown a slight recovery, the presence of heavily subsidized companies like Thales in France make it difficult for American companies to compete. Gyroscopes Precision gyroscopes are used in spacecraft to determine altitude and are essential to providing inertial navigation systems. According to the Department of Defense, there is only one domestic supplier of hemispherical resonating gyroscopes, resulting in long lead times — the report claims that the company can only produce one to two units per month. Fiber optic gyroscopes fair better with three domestic suppliers currently manufacturing them, but those companies are themselves vulnerable to overseas supply issues with their subcomponents. Infrared detectors Just one foreign manufacturer produces the substrates necessary for space infrared detectors, and the Pentagon warns that a disruption of any more than a few months of production of the substrates could negatively impact the quality and completion of American satellites. Because of this, the U.S. government has used a Defense Production Act of 1950 provision that allows it to offer economic incentives to either develop, sustain or expand domestic production of technology critical to national defense, and an Industrial Base Analysis and Sustainment program is in the works to support the remaining two American foundries for one type of substrate. https://www.c4isrnet.com/battlefield-tech/space/2019/07/02/these-4-technologies-are-big-problems-for-us-military-space/
