The pattern in one line: cheap, long-range drones have made refineries, tank farms, and export terminals reachable in a way pipelines and tankers weren't, and two separate conflicts — Russia-Ukraine and the wider Iran/Houthi-linked Middle East confrontation — have independently proven it at scale. The response is now visible in three places at once: refiners' own crude-sourcing decisions (including India's), Gulf states' defence procurement, and a counter-drone industry whose growth estimates, however imprecise, all point the same direction.

Ukraine's drone campaign against Russian oil infrastructure has escalated from a nuisance into a strategic weapon over four years of war. By 25 June 2026, Ukraine had struck Russian oil facilities more than 300 times since the full-scale invasion began on 24 February 2022, and the year-over-year escalation is stark: just 3 strikes in the war's first twelve months, rising to 13, then 92, then 138 in the twelve months to February 2026, with a further 59 strikes in the four months to June alone. Independent verification by BBC Verify and BBC Russian found that 21 of Russia's 38 large refineries had been hit since January 2025, with 14 refineries targeted in August 2025 alone.

The 2025-26 period alone accounts for nearly half of all recorded strikes since the war began — the campaign didn't just continue, it fundamentally changed pace.

The impact on Russia's own fuel supply has been severe and, by mid-2026, genuinely nationwide. Ukraine's General Staff assessed 42.74 per cent of Russian refining capacity as disabled by 4 July 2026; Finland's president separately put Russia's production and export capacity reduction at around 40 per cent in early July. Russian crude processing fell to roughly 4.1 million barrels a day in June 2026 — about 35 per cent below design capacity and 28 per cent below the five-year average — after the Omsk refinery, Russia's largest, halted operations following a strike on 6 July 2026. By 2 July 2026, 78 of Russia's 83 regions were reporting fuel shortages, 38 regions had imposed sales restrictions, and Crimea had declared a state of emergency and banned fuel sales outright. Moscow's own mitigation measures — permitting refineries to produce lower-grade Euro-3 petrol instead of Euro-5, and banning petrol and jet-fuel exports — are themselves an admission of how constrained supply has become.

Two incidents in April 2026 illustrate what "disabled capacity" means physically, not just statistically. On 29 April 2026, Ukrainian drones struck the Lukoil-operated Permnefteorgsintez refinery — Russia's seventh-largest — along with a nearby Transneft pipeline pumping station holding roughly 380,000 cubic metres of tank storage. Both caught fire; residents reported "black rain" and the smell of burning chemicals, and smoke from the blazes had spread approximately 120 kilometres by the following Friday. It followed a similar pattern to an earlier strike on the Tuapse refinery and oil terminal on Russia's Black Sea coast, which caused its own multi-day environmental disaster. Both incidents now have dedicated Wikipedia entries documenting the ongoing pollution — itself a marker of how far outside routine wartime damage these events have registered internationally.

A structurally similar, though separately motivated, campaign has been unfolding against Saudi Arabian oil infrastructure. On 2 March 2026, two drones targeted Saudi Aramco's Ras Tanura refinery — the kingdom's largest, processing more than 500,000 barrels a day and a key export hub — in an attack Saudi Arabia attributed to Iran (Iran denied involvement and pointed to Israel instead). Saudi air defences intercepted both drones, but debris caused a fire that, while contained, was serious enough that the facility shut down for roughly a week on security grounds; propane and butane exports were halted for weeks afterward, oil-product exports were rerouted to Red Sea ports, and the shutdown alone triggered an immediate spike in global oil prices. Five months later, in August 2026, Yemen's Houthi movement claimed two separate drone strikes within days of each other on Aramco's Jazan refinery (400,000 barrels a day), triggering a fire the Saudi energy ministry said was extinguished with no casualties. Both incidents echo a precedent set in September 2019, when a coordinated drone-and-missile attack knocked out roughly half of Saudi Arabia's oil production capacity at the Abqaiq processing facility and the Khurais oil field — the strike that first proved, to the entire industry, that a state-scale oil producer's core infrastructure was reachable by low-cost unmanned systems.

None of this is abstract for India, which imports the overwhelming majority of its crude and has refining capacity heavily concentrated on its western coastline, optimised for Middle Eastern and African crude arriving via the Red Sea corridor. Mangalore Refinery and Petrochemicals Limited (MRPL) became the first Indian refiner to instruct crude suppliers to avoid both the Strait of Hormuz and the Red Sea entirely in a tender seeking cargoes for delivery between 25 August and 6 September, and state-run refiners have separately suspended crude loadings from Iraq and are weighing an unprecedented option: routing Saudi crude via the Suez Canal and around the Cape of Good Hope — a far longer and more expensive voyage — specifically to avoid the Bab-el-Mandeb strait where Houthi forces have targeted shipping.

A less obvious finding from this same body of reporting is that the Red Sea and Hormuz risk, real as it is, may not be India's largest near-term exposure at all: Russia now supplies more than half of India's crude imports, and Russian Black Sea export infrastructure is itself squarely inside the zone Ukraine has been striking — meaning India's oil security today carries a layered risk from two separate conflict zones simultaneously, one of which (Russia) is proportionally the larger supplier. The Ras Tanura shutdown's own price spike is a direct illustration of the transmission mechanism: any Indian refiner buying spot Middle Eastern crude pays the global price, and that price now visibly jumps every time a Gulf refinery takes a hit.

The commercial counter-drone (counter-UAS, or C-UAS) industry has scaled its growth projections accordingly, though analyst estimates diverge sharply on the actual numbers involved — a reminder that market-sizing forecasts in a fast-moving, newly commercialised security category should be read as directional, not precise. One widely cited estimate from MarketsandMarkets puts the global C-UAS market at $9.17 billion in 2026, growing to $29.70 billion by 2031 at a 26.5 per cent compound annual growth rate; a separate estimate for the narrower "anti-drone" market segment puts 2026 value at just $2.47 billion, growing to $8.42 billion by 2031 at a comparable 27.8 per cent CAGR — a more than three-fold difference in absolute size between two analyst firms covering an overlapping category, even though both agree on the growth rate. Both estimates, and the broader trade coverage around them, point to the same driver: protection requirements for ports, oil and gas facilities, and utilities, particularly in Gulf states actively defending their own energy infrastructure.

A second analyst firm's estimate for a narrower market segment puts both the 2026 and 2031 figures at roughly a third of the numbers charted here — the growth rate is the more reliable signal than the absolute dollar figure.

That demand is now visible in specific procurement activity. In 2025, the United States and Saudi Arabia jointly ran "Red Sands," described as the Middle East's largest counter-drone exercise, testing 20 separate counter-drone systems as US Central Command works through what trade coverage frames as a doctrinal shift toward defending against small, cheap, manoeuvrable drones rather than the large, expensive missile threats air defence was originally built for. Saudi Aramco itself is reported to be in discussions to acquire interceptor drones directly — including from Israeli manufacturer SkyFall (maker of the P1-SUN interceptor) and Ukrainian supplier Wild Hornets/TAF Industries, the latter also reportedly fielding purchase interest from other Gulf states — putting Aramco, according to trade reporting, ahead of even its own government's procurement pace in this specific area. The broader pattern industry analysts point to is that national oil companies whose facilities have already been struck or credibly threatened become the fastest-moving buyers in this market, a dynamic first set by the 2019 Abqaiq/Khurais attack and now reinforced by the 2025-26 strikes on both sides of two separate wars.

Vendor material aimed specifically at this buyer segment describes a fairly consistent technical playbook, regardless of manufacturer. Counter-UAS ("C-UAS" or "CUxS") systems marketed for oil and gas sites combine multiple detection layers — radar for long-range tracking, radio-frequency sensors that pick up the communication link between a drone and its operator, electro-optical and thermal cameras for visual confirmation, and acoustic sensors tuned to propeller noise for the GPS-denied or RF-cluttered conditions a jammer-heavy environment can create — feeding a central command platform that uses AI-based signature profiling to distinguish an authorised inspection drone from a hostile one, before any jamming, GPS-spoofing, or physical interception is triggered. DroneShield, an Australian, ASX-listed C-UAS specialist, frames the energy sector's exposure explicitly around recent wartime precedent: large-scale Russian drone strikes on Ukraine's power grid that cut electricity to tens of thousands of households, a separate strike that cut power to hundreds of thousands of homes in southern Ukraine, and a drone strike on a major natural-gas field that triggered fires and outages — presented by the vendor as evidence that "critical infrastructure in stable regions is also at risk," not only facilities already inside an active war zone. On the detection-hardware side, Australian defence firm Electro Optic Systems has taken the escalation a step further with its Apollo High Energy Laser Weapon: a 100-150 kW laser that fits inside a standard 20-foot shipping container, already sold to an undisclosed NATO country, capable of destroying a drone at up to 3 km or disabling its optical sensors from 15 km, engaging roughly 20 Group-1-class drones a minute across a full 360-degree field, and able to down 200 medium-sized drones running purely on its own internal battery if mains power is cut — a capability whose main selling point, per its manufacturer, is the "dollar-a-shot" cost of a laser engagement against a drone that itself might cost only a few hundred dollars to build.
