When asked about Moscow’s military support for Iran, US President Donald Trump summed it up in three words: "A bit." Iran’s foreign minister then called the cooperation "good." Both comments line up with reporting that Russia is sharing satellite and intelligence data about US ships and aircraft with Tehran. That sounds dramatic, but the reality is more nuanced.
Eyes in the sky
Russia has a spy-satellite setup called Liana. Experts say it is the most capable Russian system still fully functional, and it was built with an eye on tracking carrier strike groups and naval targets. Pavel Luzin, a space and military specialist, says the system was designed to spot and identify navy forces as targets.
Russia also helped develop Iran’s Khayyam satellite, launched in 2022 from Baikonur. The satellite weighs about 650 kilograms, or 1,430 pounds. It orbits at roughly 500 kilometres and can resolve objects down to about 1 metre. Moscow can, in theory, receive and process imagery from Khayyam and combine it with data from its own satellites.
Iran has made public claims about strikes on the US carrier Abraham Lincoln and a US destroyer refuelling in the Indian Ocean. The Pentagon called the carrier strike claim "pure fiction," and US officials did not comment on the destroyer report.
Weapons, parts, and decades of sales
Russia and Iran have a long arms relationship. Over the years Russia supplied advanced air-defence systems, trainer and fighter jets, helicopters, armoured vehicles, and sniper rifles. These sales are worth billions of dollars.
Since strikes by the US and Israel started on February 28, Russia has, according to Lieutenant General Ihor Romanenko, continued to provide Iran with "intelligence, data, experts and components." That assistance has not included direct Russian combat intervention, and there is no mutual defence pact between Moscow and Tehran.
The relationship goes both ways. Since 2022, Iran has sent ammunition, artillery shells, firearms, short-range ballistic missiles, helmets, and flak jackets to Russia.
Drones with upgraded tricks
The Shahed kamikaze drones are part of this picture. Cheap and noisy, they have been used in large swarms. Russia spent years modernising Shaheds for the Ukraine conflict, adding speed, cameras, navigators, and sometimes basic artificial intelligence. Some of those upgrades have reached Iran.
One widely reported example involved a drone fired from southern Lebanon that struck a British airbase in Cyprus. Reporters said it contained a Kometa-B navigation module, a Russian-made unit that improves satellite navigation and provides some protection against jamming.
Russia also helped develop tactics that use waves of real and decoy drones to exhaust air-defence systems. Western officials say similar approaches are now being used in the Gulf.
British Defence Secretary John Healey suggested that Russia may be behind some Iranian tactics and capabilities. Analysts caution, however, that Iranian shortages of drones would limit the value of Russian data and tactics.
Russian expert Nikita Smagin put it bluntly: Russia supplies data and it helps, but "not much." Researchers note that after a period of very high tempo drone attacks in early March, with as many as 250 drones a day, Iran’s launches dropped to about 50 a day. Nikolay Mitrokhin of Bremen University said Iran "ran out of steam really fast."
Why Moscow does this
Helping Iran gives Russia political and economic advantages without committing troops. Higher oil prices from disruptions in the Gulf help Russia’s finances, which in turn supports Moscow’s ability to sustain its own war in Ukraine, according to Lieutenant General Romanenko.
As Iran has restricted traffic through the Strait of Hormuz, the global oil benchmark Brent topped $100 a barrel recently. That spike forced the US to temporarily ease sanctions on some shipped Russian oil. Observers say tankers originally bound for China have sometimes been redirected to other buyers as countries scramble for cargoes.
Some analysts view Moscow’s current assistance as a gesture of solidarity rather than a push for an Iranian military victory. Ruslan Suleymanov described the aid as a way for Russia to show Tehran it is not abandoned, despite the lack of a formal defence agreement.
Tehran appears to understand the limits of Russian help. Iranian strategy seems to rely on widening the conflict across the region and on economic pressure tied to rising oil prices, rather than counting on Russian military forces to turn the tide against the United States or Israel.
Bottom line
Russia is supplying Iran with useful capabilities: satellite imagery, intelligence, weapons parts, and drone know-how. The support is meaningful, but it is not a full-scale military intervention. So when President Trump said Moscow "might be helping them a bit," the description is not far off the mark.
