A plain-language guide to the unmanned systems reshaping the Russia-Ukraine war — what they are, how they work, and why they matter. No military background required.
A UAV — Unmanned Aerial Vehicle — is any aircraft that flies without a pilot on board. In the Ukraine war, when people say "drone strike," they usually mean a specific type: a one-way attack UAV that flies to a target and detonates. Think of it as a very cheap, slow cruise missile.
Russia's primary long-range strike weapon against Ukraine is the Shahed-136, an Iranian-designed drone now manufactured in Russia as the "Geran-2." It looks like a large model aircraft with a distinctive delta wing, weighs around 200kg, carries a warhead of roughly 40–50kg, and flies at around 180km/h — slow enough that Ukraine's air defence can shoot it down with everything from Patriot missiles to Soviet-era ZU-23 guns. But it costs roughly $50,000. A Patriot interceptor costs $4 million. Russia can afford to send hundreds at once.
Russia rarely sends Shaheds alone. A typical attack combines waves of drones with a smaller number of cruise or ballistic missiles. The drones arrive first — slow, audible, predictable — forcing Ukraine to activate its air defence radars and expend interceptors. The missiles follow, targeting the now-active and partly depleted defences.
The strategy is economic exhaustion. Ukraine can shoot down 75% of drones but cannot afford to keep doing so indefinitely at the current exchange rate. Russia's domestic Geran-2 production has scaled to an estimated 300–400 drones per month, possibly more. The drone has become Russia's primary means of attacking Ukrainian cities, energy infrastructure, and military logistics.
FPV drones are racing drones modified to carry explosives. The operator wears video goggles and flies the drone from a first-person view — as if sitting in the cockpit — typically at speeds of 100–150km/h over distances of 3–10km. When they find a target, they fly directly into it. They cost between $300 and $800 each.
FPVs are fundamentally different from Shaheds. A Shahed is a long-range strategic weapon that flies autonomously to a pre-programmed target. An FPV is a short-range tactical weapon flown in real time by a human operator. You cannot compare their capabilities directly — they operate in completely different domains of the battlefield. But they share one property that has made them transformative: they are cheap enough to be genuinely expendable.
Before FPVs, anti-tank warfare required either a large missile system (expensive, visible, targeted) or infantry approaching close enough to use rocket-propelled grenades (lethal). An FPV operator can sit in a fortified position several kilometres from the front and fly a drone into a tank, an ammunition truck, or — most commonly — individual soldiers. For the first time in history, infantry has become a high-priority drone target rather than a protected one.
Ukraine's Unmanned Systems Forces (USF) logged 863,911 strike flights and 99,416 enemy personnel hit between June 2025 and June 2026 alone. The scale is without precedent in the history of drone warfare. For context: the entire US drone campaign in Afghanistan over 20 years conducted fewer than 14,000 strikes.
A USV — Unmanned Surface Vessel — is a boat that operates on the water's surface without a crew on board, controlled remotely or autonomously. Ukraine has used them to conduct the most successful naval drone campaign in history, eliminating approximately one-third of Russia's Black Sea Fleet without a single Ukrainian naval vessel.
Ukraine had no USV programme before the full-scale invasion. The first successful USV strikes in October 2022 used improvised craft — modified civilian speedboats packed with explosives, guided by satellite and a camera mounted on the bow. Within two years, Ukraine had developed sophisticated purpose-built platforms capable of carrying multiple warheads, operating in coordinated swarms, and evading both electronic countermeasures and naval gunfire.
Russia's Black Sea Fleet was one of the most significant conventional military advantages it held over Ukraine at the start of the war. It blockaded Ukrainian ports, threatened amphibious landings, launched cruise missile strikes from stand-off range, and projected power into the western Black Sea. Ukraine had no surface navy capable of challenging it.
USVs changed that calculation entirely. By 2024, Russia had withdrawn its Black Sea Fleet from Sevastopol (its main Crimean base) to Novorossiysk on the Russian coast — a tactical retreat forced by the drone threat. Ukrainian grain exports resumed after Russia's blockade collapsed. The bridge linking Crimea to Russia was struck twice. The strategic value delivered by a programme that cost a fraction of a single warship is extraordinary.
| Date | Target | Outcome | Significance |
|---|---|---|---|
| Oct 2022 | Sevastopol harbour (mixed attack) | Damaged — Admiral Makarov frigate | First USV combat use at scale; proved concept |
| Jul 2023 | Kerch Bridge (truck bomb + USV) | Seriously damaged — partial collapse | Primary Russian Crimea supply route disrupted |
| Aug 2023 | Olenegorsky Gornyak landing ship | Sunk | First naval vessel sunk by USV in combat history |
| Feb 2024 | Caesar Kunikov landing ship | Sunk | Largest vessel sunk by drone to date |
| Mar 2024 | Sergei Kotov patrol vessel | Sunk | Magura V5 swarm attack — three USVs |
| 2024 onward | Black Sea Fleet withdrawal from Sevastopol | Russia relocates to Novorossiysk | Strategic withdrawal forced by USV threat |
UGVs — Unmanned Ground Vehicles — are ground-based robots operated remotely or autonomously. They represent the newest and least mature category of unmanned system in the Ukraine war, but their growth rate is extraordinary: from near-zero in 2022 to over 24,500 logged combat missions in Q1 2026 alone.
Unlike aerial drones, ground robots face unique challenges: terrain, obstacles, mud, mechanical failure under fire. The battlefield physics that makes drones relatively straightforward — three-dimensional movement, no friction, no terrain — makes ground robotics genuinely hard. Yet both sides are deploying them at scale, driven by the same logic as FPVs: keeping infantry away from the most lethal kill zones.
