Thales développe un casque optimisé pour les hélicoptères militaires

Thales va fournir à l'armée française une version optimisée du casque TopOwl, fabriqué à Mérignac (Gironde), afin d'aider les hélicoptères des forces spéciales à évoluer dans des conditions extrêmes (basse altitude, obscurité totale, atterrissage dans le brouillard...). Destiné aux hélicoptères NH90 de NHIndustries, le nouveau dispositif de réalité augmentée permettra aux pilotes d'avoir accès à la vision de nuit directement dans le viseur du casque, gr'ce à des amplificateurs de lumière, ce qui évitera l'emploi de jumelles de vision nocturne.

    Air Force’s next GPS satellite ready to boost accuracy, anti-jamming capabilities

    By: Daniel Cebul Lockheed's Martin second GPS III satellite has passed all of the U.S. Air Force's technical and safety tests and is ready to be launched, likely in 2019, according to a company statement Aug. 21. The statement marks the formal designation that the satellite is “available for launch.” The first GPS III satellite was available for launch in September 2017 aboard a SpaceX Falcon 9 rocket and is set to liftoff from Cape Canaveral Air Force Station in Florida before the end of 2018. The next satellite will launch aboard a rocket from United Launch Alliance. The new satellite constellation is expected to be a significant improvement over the current generation of satellites. According to Harris Corp., the company that provides Lockheed Martin with the satellites navigation payload, the next-gen satellites are equipped with “a Mission Data Unit (MDU) with a unique 70 percent digital design that links atomic clocks, radiation-hardened computers and powerful transmitters." This allows for signals three times more accurate than those on current GPS satellites, the company said. In addition to being more accurate, the satellite is also eight times more resistant to jamming. This model also adds and maintains signals to ensure compatibility with Global Navigation Satellite Systems and provide stronger signal integrity. Harris also unveiled an upgraded payload in November 2017 to be used for the Air Force's GPS III Follow On (GPS IIIF) program, which will begin with the 11th GPS III satellite. This next-gen payload will grant the clock signal for a new GPS III Search and Rescue (SAR) payload, and extend the satellite's service life. Lockheed Martin is expected to be the prime contractor. In June, the third GPS III satellite completed thermal vacuum and environmental testing to simulate how the satellite will hold up in the space's unforgiving environment. https://www.c4isrnet.com/c2-comms/satellites/2018/08/21/air-forces-next-gps-satellite-ready-to-boost-accuracy-anti-jamming-capabilities

    Navy Readies To Buy New Frigates As Industrial Base Wobbles

    The Navy will recompete the program after the first 10 ships are under contract, leading to a new award and another bite at the apple for the bidders who lost out the first time around. By PAUL MCLEARY WASHINGTON: The Navy will award the first contract for an ambitious new class of frigates in the coming days, several sources with knowledge of the plan said, speeding up a program that wasn't slated to get underway until later this year. After the first award for ten ships, the Navy will launch a new competition for the next ten, possibly splitting the class and giving other shipbuilders another bite at the apple. Moving forward the buy of the first of what should be 20 frigates serves more than one purpose. It locks in place one of the service's top priorities while also pushing work to the winning shipbuilder months ahead of the original schedule, just as the Pentagon worries about the cratering of global manufacturing supply chains as a result to the COVID-19 pandemic. The country's largest shipbuilders are competing for the $1.2 billion first ship, with the price settling in at a projected $900 to $950 million per ship after that. In the running are Huntington Ingalls Industries, which is thought to be offering a more lethal version of its national security cutter. There's also a joint effort between Navantia and General Dynamics Bath Iron Works with a version of its F-100 design already in use by the Spanish navy. Fincantieri Marinette Marine is offering a version of its FREMM frigate in use by the Italian navy. Finally, Austal is trying with a version of its aluminum trimaran Littoral Combat Ship. Fincantieri and Lockheed also make a version of the LCS, but decided not to submit it to the competition. Hanging over any new start shipbuilding program however is the specter of the long-troubled LCS, a vessel still working to find a role and mission within the fleet. Despite its problems, the Navy has ordered 38 of them but is walking away from the class to pursue the new frigate. Unveiling the fiscal 2021 budget earlier this year, Rear Adm. Randy Crites, deputy assistant secretary of the Navy for budget, acknowledged “we don't want to have a repeat of some of the lessons of LCS where we got going too fast,” on the frigate effort, despite speeding up the initial award. Plans call for the FFG(X) to be a small, multi-mission ship loaded out with the Aegis combat system, 32 vertical launch cells and the new SPY-6 radar system. The ship will be smaller than the Arleigh Burke destroyer, the Navy's current workhorse, but outfitted with more power generation capabilities and advanced electronic warfare systems, along with radar and anti-submarine warfare gear. Navy spokesman Capt. Danny Hernandez said in an email that the frigate “will provide increased range, endurance and survivability over previous small surface combatants,” as well as improvements in surface warfare, electromagnetic maneuver warfare and air warfare, “with design flexibility for future growth.” That's a lot of capability to fit in a relatively small package at less than $1 billion per ship. But the Navy's top brass and Defense Secretary Mark Esper have declared the fleet needs to be faster, lighter, more maneuverable and more numerous to meet the challenges of modern Chinese and Russian navies. “It's clear they need fewer large surface combatants and more smaller surface combatants,” a congressional source told me. “But whether the frigate is considered by the Secretary of Defense as being small enough” is an open question. Getting the frigate in place early will provide some stability in an uncertain time for the Navy and its industrial base. The service's long-term plans were thrown into flux in February when Secretary Mark Esper held up the release of the Navy's 30-year shipbuilding plan and the long-awaited Integrated Force Structure Assessment (INFSA), after he found the Navy's draft wanting. He assigned Deputy Defense Secretary David Norquist to lead a group through a months-long review of the plans before making them public this summer. In a letter to the House Armed Services Committee, Esper said he wants the force to grow larger than the much-discussed 355 ship fleet Navy leaders have long aspired to, with many of those new ships being smaller than the ones currently at sea, and many others unmanned. “Three months ago, I would have said, ‘oh yeah they're gonna want to build more than 20'” frigates,” the congressional source said. “But now with the intervention of the Secretary of Defense it's unclear. Maybe he's fine with just 20, and he wants them to build a lot more of something that's considerably smaller still.” Two of the shipbuilders competing, Fincantieri in Wisconsin and Austal in Alabama have a lot riding on the contract, as their big-ticket work on LCS runs out in coming years. Huntington's yards are somewhat protected because it is the only shipbuilder in America capable of building aircraft carriers, and has two more Ford-class big decks to build over the next decade, along with large amphibious ships. Lawmakers in Wisconsin, well aware of what's at stake, sent a letter to President Trump earlier this year promoting the Fincantieri Marinette Marine shipyard as best suited for the work. “We have witnessed what the loss of opportunity does to the Midwest,” the letter said. “When industry departs, so does hope.” Wrapping up the pitch for close to $20 billion worth of work over the 20 ship contract, the senators concluded by telling the president his “leadership and attention to this opportunity is vital.” There is no indication that any political weight is being put on the Navy in awarding the contract, but in an election year, with an industrial base staggering through supply chain meltdowns, the frigate contract is looming large. https://breakingdefense.com/2020/04/navy-readies-to-buy-new-frigates-as-industrial-base-wobbles/
