 Ukraine's FPV drones are getting more lethal for Russians. Ukraine is tinkering with its fleet of first-person view drones, one of the most popular drones in its battle with Russia in the air, to do more damage to Moscow's armoured vehicles as Kiev struggles with dwindling ammunition stocks from its Western allies according to Newsweek. Ukraine has said it developed armour-piercing ammunition, known as explosive-formed projectiles compatible with its fleet of FPV drones. According to Ukrainian media, it is designed for use against military vehicles with some measure of armour, including armoured personnel carriers or infantry fighting vehicles and self-propelled artillery. The ammunition can travel at 1,800 metres per second according to Ukrainian sources. Explosive-formed projectiles or penetrators are not a new technology, but a version of standard armour-piercing shaped charge rounds said military expert David Hambling. EFPs penetrate less armour than other shaped charges, which is why they are less popular, he told Newsweek. However, they provide a much longer range. The main advantage for the ammunition on Ukraine's FPV drones lies in Kiev's operators being able to trigger the round from afar. EFPs will also zip right through cages or netting, which is often used to protect vehicles from FPVs, he added. FPV drones quickly became almost emblematic of Ukraine's efforts with unmanned aerial vehicles. They can be used to record dramatic battlefield footage where the drone careened towards Russian vehicles before exploding or deployed as reconnaissance tools to guide artillery strikes. Makaylo Fedorov, Kiev's Minister of Digital Transformation, heading up Ukraine's drone efforts against Russia, told Newsweek in December that they work sometimes even more efficiently than artillery. As concern deepens over Ukraine's scarce stockpile of ammunition, the new EFP ammunition attached to FPV drones may offer some help in bridging the gap between Ukraine's ammunition stores and the reality of how many shells it needs. Belarus' Mazir oil refinery workers panicking over Ukrainian drones. The latest wave of Ukraine drone attacks on the Russian refinery system is likely to have a more meaningful impact on Russian refinery production than the ones in January and February. Since then, there has been another flurry of drone attacks across a further five refining sites, resulting in primary processing capacity outages and lower refined product exports. The recent wave of Ukraine drone attacks on Russian refinery infrastructure has been focused on primary processing capacity and is expected to have a more substantial impact than the attacks earlier this year. In this condition, Russia may use Belarus' Mazir oil refinery, but the wife of a Mazir refinery worker told Charter 97, media outlet that the plant workers are panicking about a possible drone attack on the plant. In Somnia, I've been living with these feelings for the last week. My husband works at the Mazir oil refinery. The company's workers are afraid that a drone may also fly to them. There is nowhere to leave the plant, since none of the other institutions can compete in salaries with our city-forming enterprise. At the plant, among close colleagues, everyone is just discussing this topic, what to do, how to deal with the situation, she added. I myself monitor situations through independent websites and telegram channels. Every day I ask my husband what is new, but the plant management says nothing. People go to work silently, scared. I am afraid that my children will become orphans because of political games. With the outbreak of the war, our city turned into some kind of unpredictable volcano. Either we are treating the wounded or gathering them for training camps, or there is military equipment that is scary to approach, because they will immediately mark you as a terrorist. We have actually been living in the frontline zone for two years now. And now we are still waiting for the drones to arrive. If you think about it, the Ukrainians have an absolute right to attack our plant as a source of fuel for a war against a neighbouring country, she said.
