    These three companies won contracts for DARPA’s new LongShot drone

    By: Valerie Insinna WASHINGTON — The U.S. Defense Advanced Research Projects Agency wants to create an air-launched drone that carries its own smaller weapons, a concept that brings to mind a lethal Russian nesting doll packed with missiles. If successful, the new UAV — called LongShot — could allow high-value manned aircraft like fighters and bombers to hang back at standoff distances while the drone moves forward and strikes multiple targets using its own air-launched weapons. DARPA announced Feb. 8 that it had awarded contracts to General Atomics, Lockheed Martin and Northrop Grumman for the first phase of the program, during which the companies will create preliminary designs. “The LongShot program changes the paradigm of air combat operations by demonstrating an unmanned, air-launched vehicle capable of employing current and advanced air-to-air weapons,” said Lt. Col. Paul Calhoun, a program manager for DARPA's Tactical Technology Office. “LongShot will disrupt traditional incremental weapon improvements by providing an alternative means of generating combat capability.” Under the LongShot program, DARPA plans to explore multimodal propulsion, which the organization sees as key to the drone's concept of operations. “An air system using multi-modal propulsion could capitalize upon a slower speed, higher fuel-efficient air vehicle for ingress, while retaining highly energetic air-to-air missiles for endgame target engagement,” the Defense Department stated in fiscal 2021 budget material. That way, the UAV gets the benefit of being able to traverse longer ranges, while the weapons it launches have a higher probability of destroying their intended targets. If LongShot's development is successful, the weapon could “significantly” extend the range at which a manned aircraft can engage a target while also reducing the risk to human pilots, DARPA stated in a news release. DARPA did not immediately respond to a request for comment about the value of the contracts or the future schedule of the program, although it noted in a release that companies will build and fly full-scale demonstrators during a future phase of the program. During those tests, companies will prove their LongShot UAVs are capable of controlled flight and launching weapons. DARPA started the LongShot program in FY21, requesting $22 million to begin conceptual design work. According to budget documents, the LongShot UAV could be either launched from an external hardpoint on a fighter or the internal bay on a bomber. Both the Air Force and Navy could be potential future customers. https://www.defensenews.com/air/2021/02/09/these-three-companies-got-contracts-for-darpas-new-longshot-drone

    Cobham Secures DE and S Anti-Jam Satellite Signal Contract

    March 30, 2020 - Cobham Aerospace Connectivity announces that it has been awarded a contract by the UK MOD's Defence Equipment and Support (DE&S) to research Advanced Anti-Jam techniques for the protection of navigation signals received from the Global Navigation Satellite Systems (GNSS). The contract will see Cobham conduct research to develop means to provide assured and resilient Position Navigation and Timing (PNT) information derived from the GNSS multi-constellation. Cobham was best placed to address the UK MOD's needs through its extensive background in advanced antenna technology and sophisticated signal processing capabilities. The research is set against a backdrop of increasing reliance on GNSS navigation signals in the nation's critical infrastructure and national security and the frequent interruptions of the signals either accidentally or intentionally. The more sophisticated interruptions involve the falsification of the navigation signal information for nefarious reasons such as piracy, civil disruption and military advantage. The DE&S-backed research feeds into the company's goal of taking already developed Anti Jam capability and developing a miniaturized system capable of providing advanced means of protection of the navigation signals received from the GNSS multi-constellation network. The anti-jam system will combine the use of advanced Controlled Radiation Pattern Array (CRPA) antenna technology with intelligent digital signal processing techniques not only to ensure reliable and assured navigation information, but also to derive important signal intelligence and domain awareness information regarding the source and nature of the interference and the best means of mitigation. Neil Tomlinson, Vice President Sales and Business Development at Cobham Aerospace Connectivity commented: “This contract award recognises Cobham's status as a major UK provider of anti-jam systems as well as our long history and deep experience in the areas of navigation antennas and satellite connectivity. We look forward to working with DE&S in this initial phase and subsequent work on this exciting project.” Enquiries Sales Lee Benneworth Regional Sales Director lee.benneworth@cobham.com M : +44 (0) 7595 465529 Media Alex Holt Marketing alex.holt@cobham.com M: +44 (0) 7718 120 805 About Cobham Aerospace Connectivity We are innovative system integrators with a pedigree of capability in Communications, Navigation and Electronic Warfare for aerospace and defense.
