Saab teste un brouilleur sur un Gripen

BOQUET Justine

Saab a conduit des essais afin d'évaluer son système EAJP.

L'industriel suédois a conduit début novembre des essais en vol avec un Gripen E/F lui permettant d'évaluer son système de brouillage EAJP (Electronic Attack Jammer Pod). Celui-ci vise à venir perturber les systèmes électroniques embarqués dans les aéronefs adverses et ainsi à renforcer la protection du chasseur. Par la mise en œuvre du système de brouillage, l'ambition est de rendre le chasseur invisible des radars.

    US Army’s interim short-range air defense solution crystallizes

    By: Jen Judson WASHINGTON — The U.S. Army's interim short-range air defense system, which will urgently fill a capability gap identified a few years ago in the European theater, has crystallized. The Army had already decided the Interim Maneuver-Short-Range Air Defense system would be developed around its Stryker combat vehicle, but it has now chosen Leonardo DRS to supply a mission equipment package that will include Raytheon's Stinger vehicle missile launcher, according to Col. Chuck Worshim, program manager for cruise missile defense systems with the Army's Program Executive Office Missiles and Space, who spoke to Defense News on June 28. General Dynamics Land Systems — which produces the Stryker — will be the platform integrator for the IM-SHORAD system, he added. The Army went through a selection process through the Department of Defense Ordnance Technology Consortium to determine the best collection of vendors to build prototypes. A Boeing-GDLS team was a front-runner for an interim SHORAD mission package, unveiling before any other vendor a solution in August 2017 at the Space and Missile Defense Symposium in Huntsville, Alabama. Using an Avenger system on top of the Stryker, which was the team's solution, sought to take what was already in the Army's inventory to create a system. And a SHORAD demonstration at White Sands Missile Range, New Mexico, last September saw more possibilities for the interim solution including Rafael's Iron Dome and South Korean defense firm Hanwha's Flying Tiger. But a dark horse emerged at the Association of the U.S. Army's Global Force Symposium, also in Huntsville, in March. Leonardo DRS showed an unassuming small-scale mock-up of its concept at its booth at the symposium that featured its partner Moog's Reconfigurable Integrated-weapons Platform. The platform would provide a choice of sights, direct-fire weapons and missiles, Ed House, DRS Land Systems' business development manager, told Defense News at the show. The system would be able to integrate both Stinger and Longbow Hellfire missiles, requirements for the service's IM-SHORAD solution. It also would come equipped with a complement of direct-fire weapons and sights to include the M230 chain gun and the 7.62mm coaxial machine gun. But the solution also has non-kinetic defeat capabilities and Rada's onboard multimission hemispheric radar. And that dark horse has won the opportunity to provide the mission equipment package for the IM-SHORAD prototype program. The system will also have Hellfire rails as well as an onboard sensor, according to Worshim. The Army decided to choose DRS to provide the mission equipment package because of the flexibility of its reconfigurable turret, which allows for growth opportunities should the threat change or something else change that requires a new interceptor or another capability, Worshim said. The solution also posed less intrusion to the existing Stryker platform, he added, and provided an increased level of protection as the crew reloads ammunition, which can be done under armor. While the Avenger solution was deemed technically acceptable and met requirements, one of the reasons the Army decided against using the Avenger on Stryker as the solution was because the government felt it would require major modifications to the Stryker, according to Worshim. The Army has a desire to keep the Stryker as common across the fleet as possible, Worshim said. Boeing was also looking to the government to supply Avenger turrets, of which a limited amount of those exist readily in the service's inventory, which would have been problematic when considering the Army's goal to deliver 144 IM-SHORAD systems by fiscal 2022, he explained. Now that vendors have been selected, the Army will move into a negotiation period expected to wrap up in mid- to late July. The service expects to officially award the contract to build nine prototypes by Aug. 31, but has the intention to possibly move that date up, Worshim said. Once the contracts are solidified, DRS will provide the first mission equipment package, complete with a new digital Stinger missile launcher in February 2019. Then GDLS will fully integrate the SHORAD prototype by April 2019. The final prototypes will be delivered to the service by the first quarter of fiscal 2020. As the prototypes are coming along, the Army will conduct prototype testing to see if the systems are meeting requirements. “From there, the Army will decide if this solution truly meets requirements in this respect,” Worshim said. If the solution does meet requirements, production efforts to build 144 systems — a total of four battalions — will move forward. The Army's goal is to provide the first battery no later than the fourth quarter of 2020, but that will depend on funding. If funding is lower than expected, the Army will deliver the first platoon by about that time, according to Worshim. The service has moved from receiving a directed requirement in late February 2018 to selecting vendors for the IM-SHORAD solution in just about four months, which, Worshim noted, is moving at “lightning speed” for a typical acquisition process. The hope is the process to build an IM-SHORAD solution will be used as a model for Army procurement that incorporates the “fly before you buy” concept and creates a way to rapidly understand capabilities moving forward, he said. https://www.defensenews.com/land/2018/06/28/us-armys-interim-short-range-air-defense-solution-crystallizes/

    Soldiers Will Control Robotic Combat Vehicles in Upcoming Test

    By Matthew Cox Next year, the Army plans to have soldiers fire at targets using remote-controlled robotic vehicles as part of a three-phase effort to learn how autonomous combat vehicles can make small units more effective on the battlefield. During the operational test scheduled for next March at Fort Carson, Colorado, soldiers will operate from specially modified Bradley fighting vehicles known as Mission Enabler Technologies-Demonstrators, or MET-Ds, according to a recent Army news release.The tricked-out vehicles feature remote turrets for the 25mm main gun, 360-degree situational awareness cameras and enhanced crew stations with touch screens. The first phase of testing will include two MET-Ds and four robotic combat vehicles on M113 armored personnel carrier surrogate platforms. Each MET-D will have a driver and gunner, as well as four soldiers in its rear, who will conduct platoon-level maneuvers with two surrogate vehicles that fire 7.62mm machine guns, according to the release. "We've never had soldiers operate MET-Ds before," said David Centeno Jr., chief of the Emerging Capabilities Office at the Combat Capabilities Development Command's Ground Vehicle Systems Center. "We're asking them to utilize the vehicles in a way that's never been done before." One goal for the autonomous vehicles is to learn how to penetrate an adversary's anti-access/aerial denial capabilities without putting soldiers in danger. "You're exposing forces to enemy fire, whether that be artillery, direct fire," Centeno said. "So, we have to find ways to penetrate that bubble, attrit their systems and allow for freedom of air and ground maneuver. These platforms buy us some of that, by giving us standoff." In late fiscal 2021, phase two of the effort will have soldiers conduct experiments at the company level with six MET-Ds and the same M113 surrogates, as well as four light and four medium surrogate robotic combat vehicles (RCVs) provided by industry, the release states. "The intent of this is to see how an RCV light integrates into a light infantry formation and performs reconnaissance and security tasks, as well as supports dismounted infantry operations," Maj. Cory Wallace, robotic combat vehicle-lead for the Next Generation Combat Vehicle Cross Functional Team, said in the release. Phase three is scheduled for fiscal 2023 and will add four medium and four heavy purpose-built RCVs to the mix, the release states. "This is not how we're used to fighting," Centeno said. "We're asking a lot. We're putting a lot of sensors, putting a lot of data in the hands of soldiers. We want to see how that impacts them. We want to see how it degrades or increases their performance." The family of RCVs includes three variants. Army officials envision the light version to be transportable by rotary wing. The medium variant would be able to fit onto a C-130 Hercules aircraft, and the heavy variant would fit onto a C-17 Globemaster aircraft, according to the release. Critics of the effort say it sounds very similar to the Army's failed Future Combat Systems (FCS), an ambitious effort to design a new fleet of lightweight manned and unmanned combat vehicles and other platforms designed to dominate future battlefields. Army officials have argued that the technology FCS depended on did not exist. The service spent billions on FCS, only to see it fail when then-Defense Secretary Robert Gates killed the 27-ton Manned Ground Vehicles portion of FCS in the 2010 budget while criticizing the advanced design as ill-suited to survive current battlefield threats. Army officials believe that the service's new Mobile Protected Firepower (MPF) vehicle could influence the development of the heavy RCV, the release states. In December, the Army awarded MPF contracts to two firms to build 12 prototypes each and begin delivering them to the service in early 2020. The goal is to down-select to a winner by fiscal 2022 and begin fielding the first of 504 of these lightweight tanks sometime in fiscal 2025, officials say. The heavy RCV is being designed to provide the enemy-armor killing power of an MPF with even less armor since it doesn't have to protect soldiers, the release states "An RCV reduces risk," Wallace said. "It does so by expanding the geometry of the battlefield so that, before the threat makes contact with the first human element, it has to make contact with the robots. That, in turn, gives commanders additional space and time to make decisions." https://www.military.com/daily-news/2019/07/15/soldiers-will-control-robotic-combat-vehicles-upcoming-test.html

    Marines 3-D print replacement parts for F-35, unmanned ground vehicle

    By: Daniel Cebul WASHINGTON ― A U.S. Marine Corps pilot has successfully flown an F-35B Lightning II with a 3-D printed part. The Marine Fighter Attack Squadron 121 used 3-D printing to replace a worn bumper on the landing gear of the fighter jet. Marine Corps Sgt Adrian Willis, deployed with Combat Logistic Battalion 31, 31st Marine Expedition Unit, used the 3-D printer as part of a process otherwise known as additive manufacturing. Without a 3-D printing capability, the entire door assembly would have needed to be replaced, a more expensive and more time-consuming repair. Rather than waiting weeks for a replacement the bumper was printed, approved and installed within a few days. The repair demonstrates the value that additive manufacturing technology brings to forward-deployed units. “I think 3-D printing is definitely the future ― it's absolutely the direction the Marine Corps needs to be going,” Willis said. “As a commander, my most important commodity is time,” according to Marine Corps Lt. Col. Richard Rusnok, the squadron's commanding officer. “Although our supply personnel and logisticians do an outstanding job getting us parts, being able to rapidly make our own parts is a huge advantage.” Building off the achievement with the F-35 part, the MEU's explosive ordnance disposal team requested a modification part to function as a lens cap for a camera on an iRobot 310 small unmanned ground vehicle. Such a part did not exist at the time, but Willis and the 3-D printing team designed and produced the part, which is currently operational and protecting the robot's lens. https://www.defensenews.com/industry/techwatch/2018/04/25/marines-3-d-print-replacement-parts-for-f-35-unmanned-ground-vehicle/
