Ukraine expands battlespace, analysts say

Ukraine’s drone campaign is getting wider, deeper, and more deliberate. That is the real change. For most of the war, people tracked the front line like a map problem — who held which village, who moved a few kilometers. But over the past several weeks, Ukraine has been hitting oil depots, pipeline hubs, airfields, ships, helicopters, and rear-area logistics far from the trench line, while also ramping up medium-range strikes directly on Russian forces near the front. Zelensky said on May 5 that those medium-range drone attacks are rising fast, and battlefield analysts say the deeper campaign is now part of the same strategy.

Not bigger in territory — bigger in vulnerability. Instead of only fighting Russian units where they are attacking, Ukraine is also reaching into the systems that keep those units supplied, moved, fueled, repaired, and protected. ISW’s late-April assessments describe a long-range strike campaign hitting oil infrastructure and military assets across Russia and occupied Crimea, with attacks reaching as far as 1,400 kilometers on April 28-29 and more than 1,800 kilometers in one strike on April 25. (understandingwar.org) ### Why hit oil and logistics so often? Because fuel is not just money for Russia — it is military endurance. A refinery fire is not only an economic headline. It can also mean less jet fuel, diesel, transport capacity, and slack in the system. On April 26, ISW highlighted a strike on the Yaroslavl refinery, which processes about 15 million tons of oil a year, plus a large strike package in Sevastopol that damaged ships, a radar station, an air-defense intelligence headquarters, a MiG-31, and airfield facilities. Three days later, ISW and Critical Threats described more strikes on a Transneft dispatch station in Perm, the Orsk refinery, and helicopters refueling in Voronezh.

Reuters-based reporting in late March put roughly 40% of Russia’s crude export capacity temporarily offline — about 2 million barrels per day — after Ukrainian attacks on ports and related infrastructure. Separate analysis from the Centre for Research on Energy and Clean Air said loadings at Ust-Luga and Primorsk dropped 53% in the late-March period after strikes intensified. Those numbers can move around, but the point is clear — Ukraine is finding ways to impose real system-level costs. (nbcnews.com) ### Why does this matter if Russia still pushes on the front? Because wars of attrition are not only about who advances today. They are about who can keep generating combat power month after month. Mick Ryan has argued that Russia’s strategic costs are moving in a direction Putin may not be able to reverse, and ISW says Ukraine is exploiting overstretched Russian air defenses and a huge rear-area attack surface. That does not mean Ukraine has solved the war. It means the contest is no longer just trench against trench. (bsky.app) ### What changed on Ukraine’s side? Domestic drone production, for one thing. ISW ties the increased tempo and range of strikes to expanding Ukrainian production. European backing is also shifting toward this exact capability. In mid-April, Germany committed €300 million to Ukraine’s long-range strike capacity and separately backed 5,000 mid-range attack drones, while Norway, the Netherlands, and Belgium also announced drone support or production deals. That matters because this kind of campaign only works if Ukraine can keep replacing airframes fast. (understandingwar.org) ### Can Russia just adapt? It can, and it will try. Russia still has scale, still launches heavy drone attacks on Ukraine, and still keeps pressure on eastern fronts. But adaptation costs money, air defenses, dispersal, and command attention. Every extra radar moved to protect an oil hub is a radar not covering something else. Every repair crew sent to a burning depot is one more drag on the wider war machine. (understandingwar.org) ### So what’s the bottom line? Ukraine is trying to turn Russia’s depth into a liability. That is the shift. The map still matters, but the war is increasingly being fought through logistics, infrastructure, and endurance — and that gives Ukraine a way to pressure Russia even when the front itself moves slowly.
