Hardened shelters and burning depots: the new geography of the Russia–Ukraine air war
Kyiv's deep strikes are pushing Moscow into hardening airbases that were once considered untouchable, while satellite imagery shows another rear fuel hub burning.
Satellite imagery released on 10 July 2026 shows Russia building hardened aircraft shelters around its prized Su-57 and Su-35 fighter jets — aircraft that, until recently, were treated as effectively untouchable deep inside Russian airspace. The construction work, visible across several airfields, is the most concrete admission yet that the geography of the air war has shifted: Russian bases that once sat comfortably behind hundreds of kilometres of buffer are now inside the operational envelope of Ukrainian long-range systems.
The same 24 hours brought a second set of images, this time from a different Telegram channel, showing the aftermath of a Ukrainian strike on an oil depot in Mikhailovsk in Stavropol Krai — a facility that sits inside Russia's rear fuel and energy logistics network, well beyond the front line. Two distinct pieces of evidence, published within minutes of each other, point in the same direction. Read together, they describe a country being forced to defend assets it had previously assumed were safe.
What the shelters tell us
For most of the war, Russia's most advanced combat aircraft — the fifth-generation Su-57 and the heavy Su-35 — have operated from relatively soft bases, dispersed across airfields in the country's west and south. That dispersal was itself a hedge against Ukrainian drone and missile strikes, which have grown in range and accuracy since 2024. The new satellite evidence suggests dispersal alone is no longer considered sufficient. Concrete-and-earth shelters, the kind of protection reserved during the Cold War for strategic assets, are now being built around frontline fighters.
The implication is operational rather than symbolic. A sheltered aircraft is harder to find, harder to hit, and more expensive to destroy with the kinds of precision weapons Ukraine has been able to source. It also signals that Russia is preparing for a sustained deep-strike campaign rather than expecting a quick resolution. Airbases are not hardened for a war that is winding down.
The depot in Mikhailovsk
The second piece of evidence sharpens the picture. Mikhailovsk, in Stavropol Krai, lies more than 600 kilometres from the nearest contested territory. Satellite imagery of the strike's aftermath shows damage to a fuel-storage facility that forms part of Russia's rear energy and logistics network — the sort of infrastructure that feeds rail, road, and air operations further forward.
Russian authorities have not, on the evidence available in the open source, offered a detailed on-the-record account. That is consistent with how Moscow has handled previous deep strikes: limited admission, emphasis on the adequacy of air-defence interception, and a public posture of business-as-usual. The structural reading is harder to dismiss. A fuel depot in Stavropol is not a target Ukraine would expend scarce long-range munitions on for propaganda purposes; it is an attempt to degrade the throughput of Russian military logistics.
How deep is "deep"?
Two things are worth holding in mind. First, the Russian framing — that interception rates are high and damage is limited — is not implausible on a strike-by-strike basis. Air-defence systems do engage incoming drones and missiles; some fraction of what is launched is intercepted; some fraction of what gets through fails to inflict critical damage. That is how modern air defence has always worked, and Ukraine has acknowledged the problem of saturation only intermittently.
Second, the wider pattern is asymmetric in a way that favours Kyiv over time. Ukrainian industry, with external help, has been producing long-range drones at increasing rates. Russia, whatever its declaratory statements on interception, is now spending concrete, engineering effort, and political capital on fortifying assets that were previously exposed. The economics are revealing: every hardened shelter built around an Su-57 is a shelter not built around something else, and every fuel depot that has to be rebuilt is a depot that was assumed to be beyond reach.
What remains uncertain
The available imagery does not, on its own, specify the scale of the construction programme, the number of aircraft being sheltered, or the precise weapons used against the Mikhailovsk depot. Casualty figures from the strike have not been disclosed by either side in the source material reviewed here. Russian military bloggers have, in past cases, offered competing narratives on attribution and damage assessment; this article does not rely on those accounts. What the open-source record does show is that two different classes of Russian military asset — advanced combat aircraft in their hangars and fuel infrastructure in the deep rear — are now being treated as legitimate and reachable targets by Ukrainian forces.
The staff line at this publication is that the wire coverage of the war has tended to under-weight Russia's logistical geography, treating deep strikes as anomalies. The available imagery suggests the anomalies are accumulating into a pattern.
