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.

Gareth Jennings Boeing Australia has powered up the engine of the first ‘loyal wingman' unmanned aerial vehicle it is developing in partnership with the Royal Australian Air Force (RAAF) ahead of upcoming flight trials. The milestone, announced on 15 September, follows the completion earlier this year of the unmanned aerial vehicle (UAV) that is serving as the foundation for the global Boeing Airpower Teaming System (ATS). “This engine run gets us closer toward flying the first aircraft later this year,” Dr Shane Arnott, programme director of the Boeing ATS was quoted as saying. “We've been able to select a very light, off-the-shelf jet engine for the unmanned system as a result of the advanced manufacturing technologies applied to the aircraft.” Boeing has not yet disclosed which engine it has chosen for the ATS. When it was unveiled at the Avalon Air Show in 2019, the ATS concept was named Boeing ATS (BATS). The Australian Department of Defense (DoD) said it would invest AUD40 million (USD29 million at the time) in the development. Boeing said the system represents the company's largest investment in a UAV programme outside the United States but did not disclose the amount involved. https://www.janes.com/defence-news/news-detail/boeing-fires-up-loyal-wingman-engine-ahead-of-flight-trials

DÉFENSE Le PDG de Leonardo demande à la Banque européenne d'investissement de permettre le financement des projets militaires Le PDG de Leonardo, Alessandro Profumo, a appelé à une révision de la politique de prêt de la Banque européenne d'investissement (BEI) pour lui permettre de financer des projets militaires à la suite de l'invasion de l'Ukraine par la Russie. Il a notamment déclaré que le conflit avait « considérablement modifié la position de nombreux pays européens à l'égard du secteur de la Défense » et étayé l'idée selon laquelle « il n'y a pas de durabilité sans sécurité ». La BEI, l'organisme de prêt de l'UE détenu par les États membres, sert à financer des projets qui favorisent la réalisation des objectifs de l'Union, mais elle n'est pas autorisée à investir dans des activités ou des actifs de Défense essentiels tels que les munitions et les armes. La banque a refusé de commenter spécifiquement les remarques du dirigeant, mais a souligné qu'elle joue un rôle dans le soutien de l'industrie au sens large, notamment dans les projets de recherche et de développement qui ont une approche à double usage. « Un changement dans les règles de la BEI sur la manière de financer le secteur de la défense serait très pertinent en tant que créateur de tendances pour le secteur financier », estime Alessandro Profumo dans une interview au Financial Times. En mars, la banque avait accepté de soutenir le financement d'une initiative stratégique européenne de sécurité visant à renforcer les investissements en Recherche et Développement à double usage dans des domaines tels que les infrastructures et les technologies de sécurité civile. Les propositions de l'UE de l'année dernière, sur ce qui constitue une finance socialement durable, qui auraient qualifié l'industrie de la Défense de socialement nuisible, ont depuis été abandonnées. Le rapport final est « meilleur qu'il ne l'était », mais « pas encore sur la table » analyse le PDG de Leonardo. L'accès au financement est particulièrement critique pour les petites entreprises de la chaîne d'approvisionnement du secteur, qui sont cruciales pour l'innovation. Financial Times du 5 juillet
