The United States military has released footage it says is of an unsafe intercept of a US drone by a Russian jet over the Black Sea. The US on Tuesday alleged that a Russian Su-27 fighter jet collided with one of its Reaper surveillance drones in international airspace, forcing it to crash into the sea. Russia denied it deliberately brought the unmanned aerial vehicle down.

U.S. European Command on Thursday released video of a Russian Su-27 fighter jet colliding with a U.S. MQ-9 Reaper drone over the Black Sea, March 14. U.S. officials have released video that shows a Russian Su-27 fighter jet colliding with the propeller of a U.S. MQ-9 Reaper drone. The video release by the U.S. military's European Command on Thursday came amid a race to secure the downed American aircraft. Russian ships are at the MQ-9 drone crash site in the Black Sea, a U.S. defense official told Fox News Thursday. Russia sent ships to search the debris field almost immediately following the crash.

Intensified spying by American drones near Ukraine could lead to an escalation and Russia will respond proportionally to future intelligence-gathering operations, Moscow's defence chief has told his US counterpart. The comments came in a phone conversation on Wednesday between Sergei Shoigu and Pentagon boss Lloyd Austin after the United States accused a Russian Su-27 fighter jet of colliding with one of its Reaper surveillance drones, forcing it to crash into the Black Sea. Russia denied it deliberately brought the unmanned aerial vehicle down. "It was noted that flights by American strategic lethal drones by the Crimea coastline were provocative in nature and created pre-conditions for an escalation of the situation in the Black Sea zone," a defence ministry statement quoted Shoigu as saying. "[Russia] has no interest in such a development, but it will continue to respond proportionately to all provocations."

Recovery of a US surveillance drone that crashed after being intercepted by Russian fighter jets would be challenging given the deep waters in the Black Sea, a senior United States general said, as reports emerged of Russian vessels at the crash site. Chairman of the US Joint Chiefs of Staff General Mark Milley said remains of the uncrewed MQ-9 Reaper drone, which the US claims was brought down by one of two Russian Su-27 jets clipping the drone's propeller, sank in waters as deep as 1,219 to 1,524 meters (4,000 to 5,000 feet). "It probably sank to some significant depths, so any recovery operation from a technical standpoint would be very difficult," Milley told reporters on Wednesday. Milley added it would take several days before the US would know for certain the size of the debris field. Moscow – which denies that its jets were in physical contact with the drone – said it would try to retrieve the drone wreckage as reports emerged on Thursday of US officials confirming that Russian ships had reached the crash site.

Abstract: Efficient aerial data collection is important in many remote sensing applications. In large-scale monitoring scenarios, deploying a team of unmanned aerial vehicles (UAVs) offers improved spatial coverage and robustness against individual failures. However, a key challenge is cooperative path planning for the UAVs to efficiently achieve a joint mission goal. We propose a novel multi-agent informative path planning approach based on deep reinforcement learning for adaptive terrain monitoring scenarios using UAV teams. We introduce new network feature representations to effectively learn path planning in a 3D workspace.

WASHINGTON/KYIV – Washington's top general has said the crash of a U.S. surveillance drone after being intercepted by Russian jets showed Moscow's increasingly aggressive behavior while Russia warned Washington that flying drones near Crimea risked escalation. A day after the U.S. drone went down over the Black Sea, defense ministers and military chiefs from the U.S. and Russia held rare telephone conversations on Wednesday with relations at their lowest point in decades over Moscow's invasion of Ukraine. Moscow's Defence Minister Sergei Shoigu told his U.S. counterpart, Lloyd Austin, that American drone flights by Crimea's coast "were provocative in nature" and could lead to "an escalation … in the Black Sea zone," a ministry statement said.

We demonstrate formation flying for drone swarm services. A set of drones fly in four different swarm formations. A dataset is collected to study the effect of formation flying on energy consumption. We conduct a set of experiments to study the effect of wind on formation flying. We examine the forces the drones exert on each other when flying in a formation. We finally identify and classify the formations that conserve most energy under varying wind conditions. The collected dataset aims at providing researchers data to conduct further research in swarm-based drone service delivery. Demo: https://youtu.be/NnucUWhUwLs

Secretary of Defense Lloyd Austin said during a briefing on Wednesday that the collision of a Russian jet with a U.S. drone follows a "pattern" of unsafe and risky behavior from Russia. Chairman of the Joint Chiefs of Staff Mark Milley said during a briefing on Wednesday that America doesn't seek "armed conflict" with Russia after the collision of a Russian jet and a U.S. drone On Tuesday, a Russian Su-27 fighter plane collided with a U.S. MQ-9 Reaper drone while traveling over the Black Sea, a U.S. defense official told Fox News. The collision occurred in international airspace while over international waters, with the jet in question being one of two Su-27s flying in tandem. The drone's propeller was damaged, forcing it to be ditched in the Black Sea west of Crimea, the defense official said. Secretary of Defense Lloyd Austin described the incident as a continuation of risky behavior from Russia during Tuesday's press briefing.

In 2013, former Amazon CEO Jeff Bezos predicted Prime Air, the company's then newly announced drone delivery unit, would be flying within four to five years. A decade later, the service appears to be no closer to reality than it was in 2018. However, some drone startups have had more success. Among those is Zipline, which says it's on track to complete about 1 million deliveries by the end of the year. By 2025, the company expects to operate more flights than most airlines, a feat it intends to accomplish thanks to its next-generation drone, the Platform 2 or P2 Zip. Zipline's latest drone consists of two autonomous vehicles that will work in unison with one another to deliver packages that weigh up to 8 pounds.

Defense Secretary Lloyd Austin on Wednesday said the U.S. will not stop flights in international airspace after a Russian fighter jet clipped a U.S. drone propeller, causing a crash into the Black Sea. The U.S. said on Tuesday two Russian SU-27 warplanes harassed and struck down an unmanned U.S. MQ-9 Reaper drone over international waters, forcing it to crash into the Black Sea in what could be described as "coercive signaling." If a Russia warplane is found to have purposefully downed the sophisticated $32 million intelligence collecting drone, it will be the first time the U.S. and Russia have directly exchanged blows since the war in Ukraine began. Though Moscow has denied downing the drone and claimed it crashed on its own, one report by the RAND Corporation released last year suggests this could align with Russia's known use of coercive tactics. An MQ-9 Reaper remotely piloted aircraft is parked in a hanger at Creech Air Force Base on Nov. 17, 2015 in Indian Springs, Nevada.
