Le Centre de Développement et d'Ingénierie de l'Aviation et des Missiles de l'Armée américaine (AMRDEC) va procéder à une évaluation de la technologie de roquettes à induction de Thales.

Thales a été notifié d’un contrat, d’une durée de six mois, dans le cadre d’un FTAS (« Foreign Technology Assessment Support »). Sur cette période, les lance-roquettes Telson-22 and Telson-12 ainsi que les roquettes à induction Aculeus seront évalués en France par une délégation Américaine en collaboration avec des ingénieurs de Thales.

Cette technologie digitale, déjà éprouvée au combat depuis 2009 présente des avantages opérationnels de précision et de légèreté, une plus grande facilité d’utilisation et  réduit la maintenance. En ligne avec  les objectifs technologiques de l'Armée américaine, ces caractéristiques apportent un élan très favorable à l’évaluation de ce  système d’armes 100% français, déjà opérationnel sur l’hélicoptère de combat Tigre.

US Army’s largest technical library collaborates to define its future

James Lackey, Redstone Scientific Information Center chairman and U.S. Army Aviation and Missile Research, Development and Engineering Center director, and board members reviewed near-term actions as well as far-term strategic plans during Board of Directors meeting held Mar. 11 at the U.S. Army Aviation and Missile Research, Development and Engineering Center.

The board of directors for the largest science and technology library in the Army met March 11 at the U.S. Army Aviation and Missile Research, Development and Engineering Center, or AMRDEC.

 

Redstone Scientific Information Center, or RSIC, is a unique, national asset containing a collection of specialized materials including technical reports, contractor reports, technical memorandums, informational briefs, special reports, and conference papers open to all government employees and contractors at Redstone Arsenal.

 

In addition to being the largest technical library, it is also the only joint Army/ NASA library.

 

The RSIC board of directors is composed of various Redstone organizations to include AMRDEC, NASA Marshall Space Flight Center, or MSFC, Missile and Space Intelligence Center, Space and Missile Defense Command and most recently, Missile Defense Agency as an emergent funding partner.

 

“RSIC is extremely important to NASA’s Marshall Space Flight Center as a resource for technical data on a wide variety of topics ranging from rocket propulsion to space physics, from systems design to vehicle operations,” said MSFC Center Chief Technologist and board member, Dr. Andrew Keys. “Marshall is committed to working with the ‘Team Redstone’ members to ensure RSIC has a future within our community.”

 

RSIC Board Chair and AMDREC Director James Lackey shared insight on future development for the center.

 

“One of the key challenges for RSIC is making a secure transition into a more digital future. The entire definition of what a library means is fundamentally changing,” Lackey said. “Just look at how eBooks are proliferating over traditional hardback products in your very own home. Brave new world concepts of ‘knowledge management’, ‘data mining’, and ‘cloud analytics’ prevail over traditional dusty phrases of ‘card catalog’, ‘bound periodicals’, and ‘microfiche’.”

 

Library customers can provide information on their topics of interest and the staff will set up a profile in several databases. Customers will then receive journal articles, conference papers, and report citations by email when something new is published on their subject. This service saves researchers time and keeps them informed about the latest publications in their field.

 

All registered users at RSIC also have desktop accessibility to the library’s online resources, which include access to the library’s online catalog, 20 electronic databases, the electronic books and journals, RSIC’s digital collection containing electronic documents produced by AMRDEC, MSFC, Redstone Test Center, and the Comanche Project Office.

 

Lackey said, “RSIC must keep pace with information technologies to remain viable and relevant for today’s and tomorrow’s technical workforce. This entails a variety of activities including converting existing collections into digital format, exploring use of information technology tool sets, and social media as well as potentially expanding partnerships of RSIC beyond the arsenal gates to include local academic institutions. All of this future greatness comes with a literal cost.”

 

The objective of RSIC board of directors, or BoD, was to review the current operational status of the RSIC and make decisions on near-term actions as well as far-term strategic plans, including how to secure a more stable funding future.

 

“While the answer to this question is complex and obviously depends on a variety of factors, BoD members remain committed to support the RSIC charter going forward in the best supportive manner under our current and projected budget constrained environment,” Lackey said.

Three Army technologies were in play at the recently conducted Army Expeditionary Warfighter Experiment, or AEWE, on Fort Benning, Georgia.

 

"AEWE is (Training and Doctrine Command, or TRADOC) live, prototype experimentation campaign," said Harry J. Lubin, chief of the experimentation branch, Maneuver Center of Excellence. This year, 66 industry and military technologies participated in AEWE.

 

U.S. Army Aviation and Missile Research, Development and Engineering Center, also known as AMRDEC, technologies participating in spiral "J" included the TowerHawk weapons system, Containerized Weapons System, and the Maneuver Aviation Fires Integrated Application, also known as MAFIA.

 

TowerHawk is a transportable, modular remote weapon system. Soldiers can employ it as an integrated capability of the Combat Outpost's Force Protection network or as a stand-alone capability, said Stephen W. Stillwell, Jr. project engineer, Engagement and Effects Tech Area, Mission Systems Focus Area, Aviation Applied Technology Directorate, Aviation Development Directorate. In either configuration, TowerHawk provides surveillance, enhanced perimeter defense, and an extended range of precise lethal response.

 

TowerHawk combines a modular remote weapon system consisting of a highly accurate .338 Lapua Magnum semi-auto rifle equipped with a 10 or 35 round magazine, day and night optics, and a laser rangefinder/pointer, an electro-optical/infrared sensor ball.

 

The operator controls the system remotely using secure fiber optic communications between the weapon and the ground station enabling the system to engage man-sized targets at ranges more than 1,200 meters with a reduction in civilian casualties or collateral damage, Stillwell said.

 

The Containerized Weapons System, or CWS, was designed to provide enhanced lethality and bolster force protection. This "weapons system in a box" concept combines a rapidly deployable Container Express, also known as CONEX, with the Commonly Remotely Operated Weapons Station M153 system, with various levels of firepower ranging from .50 caliber to the Javelin.

 

CWS works to augment or replace existing guard towers, said John Dillon, a mechanical engineer with the Weapons Development Directive, Platform Integration group. CWS provides a scalable, standalone force protection or threat suppression asset. This technology has been completed and qualified through testing and demonstration and is deployed in numerous locations under the management of Program Executive Office Missiles and Space, Program Management-Close Combat Weapons Systems.

 

MAFIA is a collaborative software application that allows field artillery and infantry small unit leaders to create precise, category one coordinates for accurate, timely, and predictable fires support, said Michael V. Murray, government lead and training coordinator, Battlefield Operations Software Suite team, Software Engineering Directorate.

 

The application provides full motion video from various Small Unmanned Aerial Systems, also known as SUAS, directly to the squad level, and supports cursor on target commands. The application is fully government owned, and is hardware agnostic, allowing for future hardware migration.

 

Lubin said the AEWE used the technologies in three cases: a live-fire exercise and two force-on-force events with Soldiers and Marines integrating the participating technologies into each mission.

 

The Army Test and Evaluation Center will analyze the results of the experiments and publish a final report, followed by an "experiment to action plan" to help TRADOC discover and develop "technologies of merit," Lubin said. That plan enables TRADOC organizations and the Army's Science and Technology community to place evolving technologies into the hands of deploying Soldiers earlier and more often, he said.

 

The three technologies performed well, said Lubin, who was especially complimentary of MAFIA, in its third year of experimentation at AEWE.

 

"We have over the last few years established a really great working relationship with AMRDEC. They have been linked to everything we do," said Lubin, crediting the MAFIA team's constant contact with the Maneuver Center of Excellence. "That constant contact enables this integrated development over time. We see that partnership continuing to grow over time."

 

Initial feedback from the participants of AEWE was also positive on the CWS and TowerHawks systems, he said. Both provide the sought-after expeditionary aspect for further development. "With their expeditionary emphasis, we can certainly see some utility for both," Lubin said.

 

"This was a great opportunity to hear about strategic challenges facing the Army's continuing transition as an agile, networked, expeditionary fighting force," said AMRDEC Director James Lackey, who attended a visitor's day March 3. "The overall focus at AEWE on building a networked infrastructure was a key takeaway for me. This reinforces the importance of how all of our AMRDEC systems interface along networks. It's all about linking various levels of command and control to sensors and shooters and pushing warfighting control to the lowest practical unit."

 

"AMRDEC's products of MAFIA, Containerized Weapon System and TowerHawk demonstrate networked sensor to shooter warfghting value for the expeditionary fight," Lackey said. "In my talks with the Soldiers at AEWE, they provided overall complimentary opinions of these specific capabilities. Through forums like AEWE, AMRDEC retains a tuned ear to the valuable, operational voice of the user. Their inputs drive our overall purpose and direction."

In 2014 there were further advances in sniper detection systems. The latest one (Serenity) incorporates acoustic and heat sensors as well as cameras (actually vidcams that are used in real time) and a RWS (Remote Weapons System) turret that is linked to the sensors and uses special software to quickly locate the source of the fire (rifle, machine-gun, mortar, rocket) and point the vidcams and RWS weapon (usually a 12.7mm machine-gun) at the source of the fire, enabling the human operator to immediately open fire before the enemy (especially a sniper) gets away. The software also captures video and other data for every instance that the system is alerted by what seems to be an attack. This all such events, whether they led to return fire or not, can be studied and analyzed. Serenity was developed by a U.S. Army research organization (AMRDEC) and was able to work with over a decade of similar work in this area.  Part of Serenity, the acoustic detection (called Firefly) is sometimes used separately.

 

Acoustic gunfire (sniper) detectors have been in the field for over a decade, and have gotten better each year. By 2010 over 60,000 sniper detectors had been shipped to American troops in Iraq and Afghanistan, where they were increasingly useful and generated a continuous flow of user suggestions for improvements. These were addressed and that resulted in new and improved models appearing every year.

 

The first sniper detection systems simply provided directional information about where the snipers are. The troops always wanted detectors that were faster and more accurate and after several generations of these systems showing after that first heavy use in 2004 you end up with something like Serenity. A really important improvement was manufacturers tweaking these systems to decrease the number of false alarms. Also important was improved user interface and increased accuracy. There were other reasons for all this progress, including major advances in computing power, sensor quality and software development. By 2010 the latest sniper detectors could provide nearly instant, easy to comprehend and accurate location info on the sniper.

 

One of the first, and most useful, sniper detection system was Boomerang, which was it was developed in a few months, in response to a 2004 U.S. Department of Defense request for an affordable acoustic sniper detector. Testing delayed it from entering service immediately. Boomerang was mounted on vehicles, was in wide use by 2o06 and cost about $5,000 each. Boomerang was effective enough to get initial orders for over 10,000 units, and lots of use from the troops who had it. There were two major upgrades, prolonging the service life of the system.

 

British, American, French and Israeli manufacturers have produced most of these systems, which are also sold to police organizations. The systems have varied greatly in capabilities, and price. Some of the first ones cost over $200,000, but prices have been dropping rapidly over the last five years, as the technology matured.

 

An example of the constant development of new tech was SWATS (Soldier Worn Acoustic Targeting Systems). In 2011 U.S. Army infantry in Afghanistan began receiving SWATS sniper detectors. About 1,500 a month were delivered and there were never enough of them once the usefulness of the system became known. These 183 g (6.4 ounce) devices come in two pieces. One is the sensor, which is worn on the shoulder, while the cell phone size controller, with small LCD display, is worn in front, where it can be quickly glanced at. SWATS calculates (from the sound weapon fired) direction of fire in a tenth of a second. SWATS cost about $2,000 each. SWATS was also be mounted on vehicles, and worked when the vehicle is moving at speeds of 80 kilometers an hour or more.

 

At the same time German firm Rheinmetall introduced a similar vehicle-mounted acoustic sniper detection system called ASLS (Acoustic Shooter Locating System). The Germans had been working on this for over a decade and were following the American firms that had, because of the wars in Iraq and Afghanistan taken the lead in this effort.

 

As the capability and reliability of these devices has improved, the troops came to depend on sniper detectors and these detectors saved hundreds of American lives in Iraq and Afghanistan because with a sniper detector troops could quickly turn on the enemy shooter and deliver accurate fire of their own. This made it difficult, if not impossible, for the sniper to get off a second shot and made the sniper more vulnerable to getting shot. Moreover Arab and Afghan snipers were not always good enough to always get a hit with their first shot and the nervousness created by the knowledge that the American troops would quickly fire where the sniper was because of sniper detectors made it even more likely that the first shot would miss. It got to the point where trying to get off a second shot was suicidal and Taliban and Iraqi snipers were trained to only take a first shot if they were certain of a hit and be ready to immediately duck and move after that first shot.

 

The new Serenity system is meant for base protection or mounting on vehicles. Parts of the Serenity system were sent to Afghanistan in 2012 for field testing.

US Army opens acquisition for counter-UAS weapon system

 

Mar. 24, 2014 By Erik Schechter  - FG

 

New York - Concerned about the emerging threat of unmanned aircraft, the US Army is canvassing American defence contractors for information on systems that can detect, classify and destroy drones of varying sizes.

 

According to the request for information (RFI), the army’s Aviation and Missile Research, Development, and Engineering Center (AMRDEC) is open to both “kinetic and non-kinetic options” – the latter referring to lasers.

 

The US Navy has already placed a laser weapon system demonstrator aboard the destroyer USS Dewey and tested the weapon against target drones in June 2012. The Army has likewise tested a vehicle-mounted Boeing high energy laser mobile demonstrator against mortar rounds and drones. However, there is no programme of record among the services to develop such a directed energy weapon.

 

Another interest of ARMDEC is that proposed systems be able to operate at both at the brigade-and-above and brigade-and-below echelons, which have their own network connectivity issues and levels of situational awareness.

 

The RFI, for example, notes that those at the tip of the spear resemble those homeland security operators in terms of the ad hoc nature of their deployment and size of their area of operation.

 

Indeed, the systems proposed should be designed for both overseas and domestic operations, the RFI states.

 

Contractors have until April 1 to answer the RFI, with selected respondents invited to two-day workshop starting April 30 at Redstone Arsenal, Ala.

 

The RFI opens the acquisition phase of the army’s pursuit of a capability to defeat unmanned aircraft.

 

Last year, the army’s armaments research, development and engineering center (ARDEC) at Picatinny Arsenal staged an experiment.

 

The center integrated a fire control radar with existing weapon systems. Using a “novel warhead design”, a gun-launched munition destroyed a small-class unmanned aircraft, according to army documents.

 

One challenge in the fight against unmanned aircraft is the cost. The army has highly capable air defence batteries, but their cost may seem excessive if used against a small unmanned aircraft.

 

The ARDEC experiment focused on a “low-cost-per-kill weapon system”, the army says.

AMRDEC conceptual renderings of potential future JMR configurations

AMRDEC conceptual renderings of potential future JMR configurations

 

April 25th, 2013 by Kris Osborn - defensetech.org

 

U.S. Army officials plan to award up to four design contracts by the end of fiscal year 2013 for vendors to build the Joint Multi-Role (JMR) demonstrator aircraft, a next generation helicopter fleet, Army leaders said Thursday.

 

Current plans call for two JMR technology demonstrator aircraft to be designed and built for a first flight by sometime in 2017, said Todd Turner, director for the Army’s Research and Technology Air Portfolio.

 

“This is an S&T [Science and Technology] effort for the development of a new, medium-class platform. The goals are to design, fabricate and demonstrate an advanced vertical lift vehicle with a combat radius of 424 kilometers, that’s an 848 kilometer range, un-refueled, at speeds of up to 230 knots,” Turner said at the National Defense Industrial Association’s 14th Annual Science & Engineering Technology Conference/Defense Tech Exposition, National Harbor, Md.

 

A key goal for the program is to be affordable, and develop an aircraft that can reach much greater speeds and extend mission possibilities without compromising an ability to hover, Turner said.

 

Army officials said the S&T effort is designed to lower risk, reduce costs and inform requirements for what will be a Future Vertical Lift formal program of record designed to deliver new aircraft by 2030.

 

“We’re currently completing what we call configuration trades and analysis portions of this effort which will finish this year. The trades we considered were cost, weight and power requirements, mission equipment packages and life-cycle costs.  All configurations were considered,” Turner said.

 

The configurations currently being examined include a tilt-rotor possibility, like today’s Marine Corps and Air Force V-22 Osprey as well as various compound configurations such as air vehicles with a rear-thrusting mechanism and co-axial rotorblades, Army officials explained.

 

The service is evaluating responses to an Army solicitation to industry to build designs. Service officials plan to down select to two design teams by the fourth quarter of fiscal year ’14, Turner said.

 

The JMR effort also plans to include next-generation mission equipment and avionics along with integrated sensors and weapons systems.

 

Turner said Army S&T is working on advanced rotor designs, autonomy algorithms and concept analyses wherein they assess air-vehicle design methods.

 

“We currently have a good handle on how to build systems when we have a database. What we are trying to do is move towards where we can design new systems at a more rapid pace. Get that design closer to what the air vehicle will look like, he said.

 

The FVL aircraft is slated to be powered by an Improved Turbine Engine Program (ITEP), a more powerful, 3,000-horsepower, more fuel-efficient engine also being informed by an ongoing S&T Program, Advanced Affordable Turbine Engine effort.

 

“It’s transitioning out of S&T this year to the ITEP program. It’s showing benefits of 25-percent reduced burn rate and a 35-percent reduction in production and maintenance costs,” Turner said.

 

Army S&T is also in the early phases of developing the Future Affordable Turbine Engine, a 7,000-horsepower heavy class engine for larger rotary platforms such as the CH-47 Chinook.

 

“We’re developing material and component technologies for the compressor and turbine sub-systems,” he added.
