    U.S. ARMY SELECTS LOCKHEED MARTIN AS INTEGRATED SYSTEMS DEVELOPER FOR AUTONOMOUS CONVOY PROGRAM

    DALLAS, July 30, 2018 /PRNewswire/ -- Lockheed Martin (NYSE: LMT) was selected by the U.S. Army's Tank Automotive Research, Development and Engineering Center (TARDEC) as the Integrated Systems Developer for its Expedient Leader Follower (ExLF) program. In this role, Lockheed Martin will lead a three-year effort to develop, integrate and test unmanned prototype systems for supporting leader/follower convoy activities within an asymmetric threat environment. Soldiers will conduct operational technology demonstrations using the prototypes developed in the ExLF program to establish operating procedures and shape future programs of record. "We are leveraging 15 years of experience in developing autonomous capabilities for our customers," said Gaylia Campbell, vice president of Precision Fires & Combat Maneuver Systems at Lockheed Martin Missiles and Fire Control. "Our goal as the Integrated Systems Developer is to help coordinate a number of systems and vendors in achieving mature, reliable autonomous convoys to support our warfighters in complex environments." Soldiers conduct resupply convoys within an asymmetric threat environment compounded by long sustainment missions, adverse weather/environment and night operations. These conditions adversely impact operator safety, degrade driver/operator situational awareness and reduce resupply efficiency. "The Expedient Leader Follower effort will equip a number of existing military ground vehicles with scalable robotic technology through the integration of modular kits, common interfaces and an open architecture to increase operator safety, improve situational awareness and increase resupply efficiency," Campbell said. About Lockheed Martin Headquartered in Bethesda, Maryland, Lockheed Martin is a global security and aerospace company that employs approximately 100,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. This year the company received three Edison Awards for ground-breaking innovations in autonomy, satellite technology and directed energy. https://news.lockheedmartin.com/2018-07-30-U-S-Army-Selects-Lockheed-Martin-as-Integrated-Systems-Developer-for-Autonomous-Convoy-Program

    Future Combat Air System: Owning the sky with the Next Generation Weapons System

    June 17, 2020 - When facing today's uncertainties, air superiority, which was underpinning western military operations for over 40 years, is no longer a given thing. The playing field is levelled by opponents' constant investment in integrated air defence systems, hypersonic weapon technologies and low observability technologies. Western air forces need to regain their ability to counter threats by accessing highly contested environments in a scalable, flexible and dynamic way rather than a local and static one. By intelligently teaming sixth generation manned fighters with unmanned platforms, the Next Generation Weapon System or NGWS will provide European air forces & navies with capabilities well beyond existing fighters. With no agreed definition of a sixth-generation fighter, Airbus' understanding is that such a New Generation Fighter or NGF will be a more sophisticated and connected platform than what currently exists. The NGF will set the next level of survivability in terms of passive stealth (signature reduction and electromagnetic emission control) and active stealth (electronic counter measures). The heart of the NGF will be provided by its extremely capable avionics and sensor suite. The increase in processing power, storage and connectivity will grant the pilot with greatly heightened situational awareness and the ability to rely not only on its own sensors and effectors, but also on other platforms' ones. Combined with the introduction of artificial intelligence and the ability to team with unmanned platforms, the NGF will become a battlefield management platform capable of operating deep within the enemy airspace. Powerful engines equipped with thrust-vectoring nozzles combined with high-performance flight control system will ensure the NGF's manoeuvrability, speed, and range. Innovative effectors will provide the fighter with unprecedented firepower, ranging from stand-off kinetic loads (including hypersonic ones) to directed energy weapons (lasers and microwaves) to electronic warfare capabilities (including cyberattack). However, more sophistication also means higher development costs leading to a declining number of platforms and/or effectors. Eventually such dangerously low levels result in critical availability levels. This is problematic, as operational studies indicate that penetrating contested environments will require an adequate number of manned platforms. Hence, it is important to set the right level of capabilities for the NGF by taking a holistic approach when right sizing its stealth, velocity, manoeuvrability, range, sensing and effects generation's capabilities. The NGF alone will not suffice for the most demanding missions in highly contested environments. To counter such threats, the NGF will team with unmanned platforms called Remote Carriers or RCs acting as force multipliers. Adding capabilities in a scalable and flexible manner will enhance the overall mission effectiveness, efficiency and survivability of the NGWS. RCs will be a family of unmanned platforms ranging from 200 kilograms for disposable RCs, to under 2 tons for recoverable ones and even several tons in the case of loyal wingmen. Airbus is currently studying and optimising with users their design. The RCs will provide various non-kinetic effects (Target Acquisition and Reconnaissance, Airborne Electronic Warfare) as well as kinetic ones (A2G SEAD/DEAD and Strike). With “packs” of RCs teaming with NGFs, the NGWS will clearly establish a new operational dimension. An augmented level of effectiveness will be achieved by opening new fields of tactics based on collaborative combat, the use of deception and numeric superiority. Efficiency will improve by ensuring the required mix of capabilities for a given mission is deployed. The NGF will stay at a safe stand-off distance whilst closer RCs deal with the threats, thus keeping the pilots out of harm's way and increasing the manned platform's survivability. Within the NGWS, the Air Combat Cloud or ACC will connect the manned and unmanned platform and provide the teaming intelligence for faster collaborative combat. The ACC will deliver common situational awareness by instantaneously capturing, sharing, merging and processing massive amounts of data from all connected NGFs and RCs. The ACC's warfare analytics and real-time coordination will provide better situational awareness, tactical options, decisions and collaborative effects Airbus has a leading role within the Next Generation Weapon System programme programme which will be the core of FCAS. Airbus is Dassault's main partner for the NGF and the lead for the RCs and the ACC with MBDA and Thales as its respective main partners. This will benefit Airbus' sites in securing work and maintaining technological excellence for decades to come.

    A Guide To U.S. Military Helicopter Modernization

    Graham Warwick | Aviation Week & Space Technology From armed scout to heavy lift, modernizing rotorcraft fleets has become a priority for the U.S. Defense Department. But whether the U.S. Army and other services will have the budgets to fulfill its ambitious renewal plans remains to be seen. http://aviationweek.com/defense/guide-us-military-helicopter-modernization
