  Pentagon Creates ‘Do Not Buy’ List of Russian, Chinese Software

  Increasingly alarmed at foreign hacking, DOD and intelligence officials are racing to educate the military and defense contractors. The Pentagon is warning the military and its contractors not to use software it deems to have Russian and Chinese connections, according to the U.S. Defense Department's acquisition chief. Officials have begun circulating a “Do Not Buy” list of software that does not meet “national security standards,” Ellen Lord, defense undersecretary for acquisition and sustainment, said Friday. “We had specific issues ... that caused us to focus on this,” Lord told reporters at the Pentagon. “What we are doing is making sure that we do not buy software that's Russian or Chinese provenance,” she said. “Quite often that's difficult to tell at at first glance because of holding companies.” The Pentagon started compiling the list about six months ago. Suspicious companies are put on a list that is circulated to the military's software buyers. Now the Pentagon is working with the three major defense industry trade associations — the Aerospace industries Association, National Defense Industrial Association and Professional Services Council — to alert contractors small and large. https://www.defenseone.com/threats/2018/07/pentagon-creates-do-not-buy-list-russian-chinese-software/150100/

  General Atomics Advances SeaGuardian Systems

  by David Donald - January 20, 2021, 6:53 AM General Atomics Aeronautical Systems Inc. (GA-ASI) has revealed that it has completed the development and testing of a self-contained anti-submarine warfare (ASW) package, the first such equipment for an unmanned aircraft system (UAS). The package comprises podded sonobuoy dispenser systems (SDS) and a sonobuoy management and control system (SMCS). GA-ASI has been studying unmanned ASW capability for some years, demonstrating sonobuoy remote processing capability from an MQ-9A Reaper in 2017. Subsequently an SMCS has been added, and the SDS has been developed. It employs a pneumatic launch system, and each pod can carry up to 10 A-size sonobuoys or 20 G-size buoys. On November 24 last year GA-ASI carried out a trial at the U.S. Navy's Pacific range in which a company-owned MQ-9A Block 5 released seven SSQ-53G Directional Frequency Analysis and Recording (DIFAR) and two SSQ-62F Directional Command Activated Sonobuoy System (DICASS) sonobuoys, and a single SSQ-36B bathythermograph buoy. Using a General Dynamics Mission Systems-Canada UYS-505 processing system the trial successfully tracked an MK-39 expendable mobile ASW training target (EMATT) for three hours, data being relayed by a satcom link to the Laguna flight operations facility at the Yuma Proving Ground in Arizona. The ASW capability is being developed for the SeaGuardian configuration of the MQ-9B SkyGuardian, which can carry up to four SDS pods under its wings. The SeaGuardian is intended to perform as a stand-alone maritime patrol asset or to act with traditional maritime patrol aircraft as part of a manned-unmanned team. A key part of the SeaGuardian mission set is a surveillance radar, and GA-ASI is working with Leonardo to integrate the Seaspray 7500E V2 AESA radar into the UAS's centerline pod. The radar offers a variety of modes, including inverse synthetic aperture radar that works with the automatic identification system (AIS, a form of maritime IFF) to provide accurate identification of detected surface targets. It can spot submarine periscopes and humans in the water during search and rescue operations. A high-definition optical/infrared full-motion video capability is also included. Another option from Leonardo is the SAGE electronic surveillance system. GA-ASI reports that two undisclosed export customers have ordered the SeaGuardian capability, which was included in the recently approved request for up to 18 MQ-9Bs from the United Arab Emirates. In its standard SeaGuardian configuration the MQ-9B has an endurance of more than 18 hours and can mount an eight-hour patrol at a radius of 1,200 nm. Another store that has recently been trialed by GA-ASI is the Legion Pod, in this case, the carrier being the company's jet-powered Avenger remotely piloted aircraft. The Legion Pod, which is carried by F-15 Eagles, features a Lockheed Martin IRST21 infrared search and track sensor in its nose and datalinks to network the sensor and carrier with other platforms. n early January GA-ASI was selected to support the U.S. Air Force's Skyborg Vanguard program that is developing artificial intelligence/machine-learning autonomous capabilities for future combat aircraft. Two company-owned Avengers are being modified with updated links and the Skyborg System Design Agent software to support this activity, which will test the ability of manned aircraft to control the Avengers in flight and to pass critical mission information between them. https://www.ainonline.com/aviation-news/defense/2021-01-20/general-atomics-advances-seaguardian-systems
