European navies try to keep up in cat-and-mouse game of seabed warfare

The sheer number of undersea cables and pipelines crisscrossing the oceans makes it easy for attackers to cover their tracks, according to experts.

    General Dynamics, AeroVironment join forces to give combat vehicles their own drones

    By: Valerie Insinna WASHINGTON — General Dynamics and AeroVironment are teaming up to integrate ground combat vehicles with drone technology in preparation for two high-stakes Army and Marine Corps vehicle programs, the companies announced Oct. 8. General Dynamics Land Systems and AeroVironment plan to network GD's entrant for the Marine Corps' armored reconnaissance vehicle, or ARV, program with the drone makers' Switchblade missile and the Shrike 2 unmanned aerial system still in development by the company, said Dave Sharpin, AeroVironment's head of tactical UAS. The first tests will begin this fall. The recently unveiled Shrike 2 is a hybrid vertical-takeoff-and-landing drone, with rotors that allow it to take off and land like a helicopter. It also has fixed wings to provide more endurance and the ability to fly like an airplane. It “will be the eyes in the sky, going out and doing the reconnaissance mission, finding things, reporting them back, and then once we have that situational awareness, then a Switchblade will be launched if we want to go do something kinetic with the target,” he said. The hope, Sharpin said, is to fill a need expressed by the Marine Corps but also relevant to the Army — a vehicle that can interface with a UAS that is organic to it, as well as a new way to strike targets that would be found by the drone. Ultimately, the companies believe they can parlay that concept into offerings for both the Marine Corps' ARV program as well as the Army's Next Generation Combat Vehicle. “The purpose of this partnership is to deliver a decisive advantage to ground combatants, to see first and strike first, across the tactical landscape,” Don Kotchman, U.S. vice president and general manager of General Dynamics Land Systems, said in a statement. “We're confident this integrated capability, expanding the warfighter's situational awareness, survivability and over-the-next-obstacle lethality, will define the market for years to come."

  • Helicopter drone loses weight, lengthens endurance, but will the change attract customers?

    Helicopter drone loses weight, lengthens endurance, but will the change attract customers?

    By: Beth Stevenson FARNBOROUGH, England — UMS Skeldar has launched a new version of its flagship unmanned helicopter that has a longer-endurance capability, as the company continues its aggressive campaign to promote the system for a number of ongoing international naval requirements. The Skeldar V-200B has a five-hour endurance due to a 10-kilogram weight reduction in the aircraft, something the company claims will up its appeal because of the increased performance and reliability. The new model is now the baseline offering that UMS Skeldar will pitch to customers. UMS Skeldar is a joint venture between Saab and UMS that formed in 2015 to primarily promote the V-200, a UAV that had previously struggled to secure customers despite years of development and marketing by Saab. “It [the V-200B] is almost a completely new aircraft — a new build since the Saab days,” David Willems, head of business development at the company, told Defense News. The "B" model is the result of work carried out under the partnership, he added, and features new GPS antennas and software in addition to the weight decrease, as well as better fuel consumption due to engine modifications. Endurance can be increased, or an extra 10 kilograms of payload can be carried by Skeldar, Willems said. Notably, the way the V-200B has been developed will allow for the drone's industrialization, moving from one-off manufacture, as was the case with the previous variant, to serial production. The Asia-Pacific region is the most active market for Skeldar, Willems says. The company is seeing potential in South Korea, and it has been specifically targeting Australia for some time now, where it is expanding its industrial base to potentially support work transfer. “It is a very interesting time there, and we are building a small Australia ecosystem,” he said. Australia is acquiring a number of types of unmanned systems under ongoing programs, seeking systems such as ship-based UAVs under its Project Sea 129 Phase 5 effort, supporting its aim to operate a comprehensive fleet of unmanned aircraft that includes the Insitu ScanEagle and Northrop Grumman MQ-4C Triton. Skeldar is most often pitched against Schiebel's unmanned Camcopter helo, a system that has seen more commercial success in both the military and civil markets, although UMS Skeldar has been demonstrably active in marketing its system since the joint venture was formed. A heavy-fuel variant of Camcopter has been undergoing trials in Australia under work that will act as risk-reduction efforts for the Project Sea 129 Phase 5 program. UMS is also active in Germany where it is teaming with ESG to pitch to the Navy for similar requirements to Australia. The company has delivered Skeldar to Indonesia, which has used it to assess operating a UAV of this type, although little news on the outcome of that work has been revealed by either the Indonesian government or the company. https://www.defensenews.com/digital-show-dailies/farnborough/2018/07/16/helicopter-drone-loses-weight-lengthens-endurance-but-will-the-change-attract-customers/

  • Stealthy UAS Unveiled For USAF Target, Loyal Wingman Needs

    Stealthy UAS Unveiled For USAF Target, Loyal Wingman Needs

    Steve Trimble A small start-up company in California has unveiled a new proposal for a stealthy unmanned aircraft system (UAS) to offer the U.S. Air Force as a “fifth-generation” target drone or a low-cost attritable aircraft. Tehachapi, California-based Sierra Technical Services, a company founded by previously retired Lockheed Martin Skunk Works engineers, unveiled the first photos of the completed Fifth Generation Aerial Target (5GAT) prototype after completing engine tests on the ground. A first flight of the 5GAT is scheduled in early 2020. The name of the aircraft is derived from its origins as a prototype funded by the Defense Department's Director of Operational Test and Evaluation (DOT&E), says Roger Hayes, president and CEO of Sierra Technical Services. Several years ago, DOT&E recognized an emerging gap for a new target drone that could fly as a surrogate for fifth-generation fighters emerging in Russia and China such as the Sukhoi Su-57 and AVIC Chengdu J-20. In 2017, DOT&E awarded Sierra Technical Services a $15.9 million contract to develop the 5GAT prototype, Hayes said. The pace of assembly has been dictated by the availability of parts cannibalized from other military aircraft, such as the engines and metallic components from the Northrop T-38 trainer and F-5 fighter, as well as aileron actuators from the Boeing F/A-18, Hayes said. Sierra Technical Services supplemented its revenue as assembly continued by working on other programs, including supplying components for the Kratos XQ-58A Valkyrie. As development continued, the Air Force started to develop interest in a fifth-generation target. The service has awarded Lockheed Martin a contract to develop the AIM-260 Joint Advanced Tactical Missile, which is being designed to counter the PL-15 missile fielded on China's J-20 fighter. The Air Force needs to test the AIM-260 and other missiles against a representative threat. Last May, the Air Force released a request for information for the Next Generation Aerial Target, which included a version that can replicate fifth-generation fighter attributes, such as a stealthy airframe with canted tails and serpentine inlet ducts. The Air Force also is developing a concept to pair manned fighters such as the F-22 and F-35 with an unmanned partner, known sometimes as a Loyal Wingman. The Air Force Research Laboratory (AFRL) funded Kratos' XQ-58A, which completed a first flight in March. AFRL also plans to demonstrate a UAS controlled by a “software brain” using artificial intelligence. This Skyborg program is sometimes considered a follow-on for the XQ-58A program, but Hayes said Sierra Technical Services could offer the 5GAT for the Skyborg contract. https://aviationweek.com/defense-space/stealthy-uas-unveiled-usaf-target-loyal-wingman-needs
