Ukrainian company 3DTech produces explosive-packed drones for the country's military amidst the conflict with Russia.These drones are vital for the military to fend off invading forces and are part of Ukraine's growing weapons industry.Radio frequency connections used in drones are vulnerable to Russia's electronic signal-jamming tactics.Fiber-optic drones have emerged as a solution, providing resistance to jamming and higher-quality video transmissions.3DTech expects to produce 1,200 FPV drones in March, with half being fiber-optic drones.The company's production involves assembly of carbon fiber frames, 3D printing of fiber-optic spools, and rigorous testing.Fiber-optic drones are tested with weights mimicking explosive payloads and are capable of traveling long distances with significant payloads.The drones are tested in realistic conditions outside Kyiv before being sent to Ukrainian soldiers on the front lines.3DTech faces challenges in talent management and training personnel to work with the technology efficiently.Ukraine's defense industry heavily relies on companies like 3DTech to produce FPV drones as part of its military strategy.
