The military is this close to nabbing Gremlins from midair
WASHINGTON — The U.S. military recently came within inches of successfully retrieving three unmanned air vehicles in flight with a C-130 aircraft, bringing the Gremlins program tantalizingly close to a significant milestone.
The Defense Advanced Research Projects Agency, the Pentagon's emerging technology arm, wants to demonstrate the ability to launch and recover four cheap, reusable unmanned aerial vehicles — the Gremlins — within 30 minutes in flight. The program uses X-61A Gremlins Air Vehicle (GAV) developed by Dynetics, a Leidos subsidiary. The GAVs are built to dock with a C-130 aircraft via an extension, similar to an airborne refueling operation.
Dynetics secured a 21-month, $38.6 million award for the third phase of the Gremlins effort in 2018.
While GAVs are relatively small, they have a range of more than 600 miles and can be equipped with a variety of sensors and technologies for different missions. The ability to distribute and collect GAVs from the air could keep them beyond the range of adversary defenses, according to DARPA, expanding the potential impact of unmanned aerial vehicles on the battlefield. Once recovered, GAVs are expected to be mission ready within 24 hours.
In the latest demonstration Oct. 28, DARPA made nine attempts to collect the GAVs with a docking mechanism extended from the C-130 aircraft. While none of the attempts was successful, with each GAV eventually parachuting to the ground, DARPA insisted the effort validated all autonomous formation flying positions and safety features.
“All of our systems looked good during the ground tests, but the flight test is where you truly find how things work,” said Scott Wierzbanowski, program manager for DARPA's Gremlins effort, in a Dec. 10 statement. “We came within inches of connection on each attempt but, ultimately, it just wasn't close enough to engage the recovery system.”
Given the GAVs' performance and the data collected over the nine attempts, Wierzbanowski said success is imminent.
“We made great strides in learning and responding to technological challenges between each of the three test flight deployments to date,” he said. “We were so close this time that I am confident that multiple airborne recoveries will be made in the next deployment. However, as with all flight testing, there are always real-world uncertainties and challenges that have to be overcome.”
The next attempt will take place in spring 2021.
While the Gremlins effort is ongoing, the U.S. Army has made strides in its own effort to retrieve small drones midair. During a recent demonstration, the Army was able to snag air-launched effects (ALE) — effectively small drones — from the air using the flying launch and recovery system (FLAReS). FLAReS uses a hook to catch the ALEs by the wing in flight, saving them from the wear and tear of a belly landing on the ground.

UK Competition: developing the Royal Navy’s autonomous underwater capability
The Defence and Security Accelerator (DASA) is looking for innovative solutions that inform future capability and understanding of utility of extra-large unmanned underwater vehicles (XLUUVs). This competition is part of the Royal Navy's efforts to better understand and shape cutting edge capabilities; a strategy of exploration and analysis has been adopted to inform capability and requirements of ‘Maritime Autonomous System' use for future Royal Navy operations. A total of £2.5m is available to fund one proposal in a 2 stage process consisting of an initial research, design and re-fit stage and a subsequent testing and trialling stage. Proposals must be submitted by midday (BST) on 11 June 2019. Queries should be sent to accelerator@dstl.gov.uk https://www.gov.uk/government/publications/competition-developing-the-royal-navys-autonomous-underwater-capability

Germany’s Defence Ministry is under the gun to name a Tornado replacement
By: Sebastian Sprenger COLOGNE, Germany — You can count on Germany to stir the pot of nuclear weapons sharing amid a global pandemic. Such was the case in the past few days in a country that, armed with a superb health care system and a relatively low COVID-19 mortality rate, is seen as a model for managing the coronavirus crisis. But as of Sunday afternoon, the national security community was abuzz about a news report saying Defence Minister Annegret Kramp-Karrenbauer effectively promised her U.S. counterpart that the ministry will buy 45 F-18 jets from Boeing. The Der Spiegel report comes after news broke a few weeks ago that Berlin planned to acquire a mix of Airbus Eurofighter jets and Boeing F-18s for a smattering of air warfare jobs too demanding for the country's aging Tornado fleet. Those jobs include flying conventional fighter-bomber missions, jamming enemy air defenses and carrying U.S. nuclear-tipped gravity bombs to hypothetical World War III targets somewhere eastward, per NATO's so-called nuclear sharing deal. According to Der Spiegel, Kramp-Karrenbauer sent U.S. Defense Secretary Mark Esper an email last week detailing her ministry's wish to buy F-18s not only for the atomic mission — which comes as little surprise — but also for the electronic warfare role. That reported promise stung Eurofighter advocates — even those who might begrudgingly accept an American product for the nuclear mission — because Airbus has plans for a souped-up jamming plane that it wants to see in Germany's inventory. In short, the Eurofighter crowd wants nothing more than Berlin to pick a pure Eurofighter fleet, arguing that the F-18′s shelf life is expiring in U.S. budget planning anyway, and that the Boeing jet is no closer to nuclear weapons certification than any other aircraft. The German Defence Ministry has always signaled it will take into account industrial policy considerations in the Tornado-replacement question. So strongly did senior leaders believe in the idea of a keeping the European industrial base humming toward an eventual Franco-German aerial über-weapon that they nixed Lockheed Martin's F-35 from the competition. But keeping American aircraft entirely out of the loop has always seemed a nonstarter. A ministry spokesman on Monday said Kramp-Karrenbauer's missive to Esper was only meant to test the waters regarding America's ability to start delivering those planes when the actual acquisition program gets underway in a few years. A formal decision on replacing the Tornados had initially been expected by the end of March. But as the coronavirus crisis unfolded, that decision was pushed to after Easter. Kramp-Karrenbauer is expected to announce her plans before the parliamentary Defence Committee on Wednesday, where she is likely to face opposition from lawmakers of the SPD coalition partner. Until then, Germans have yet another puzzle to discuss, as an increasingly divisive debate unfolds here over reopening the country. https://www.defensenews.com/global/europe/2020/04/20/germanys-defence-ministry-is-under-the-gun-to-name-a-tornado-replacement/
