UKRAINE’S ARMED FORCES are turning up the warmth. Previously two weeks our evaluation of satellite data has detected 907 fires more likely to be war-related in Russian-held territory in Ukraine. That’s greater than 4 instances as many as within the two weeks earlier than (see chart). From Kharkiv to Kherson exercise alongside the frontline, and obvious strikes on the Russian rear, are selecting up. The final time one thing like this occurred, final autumn, it preceded Ukraine’s spectacular beneficial properties within the south.

Our system depends on satellites that circle over Ukraine twice a day and makes use of thermal imaging to detect high-temperature occasions in locations not obscured by clouds. We use a machine-learning system to estimate whether or not these occasions are associated to the struggle, by evaluating patterns with what was noticed earlier than Russia’s full-scale invasion in 2022. It’s removed from excellent, nevertheless it gives a constant and impartial information to possible navy exercise within the nation.

The newest studying, on Could twenty fifth, reveals a spike in high-temperature occasions in Russian-held areas (we use maps produced by the Institute for the Examine of Conflict, a think-tank, to evaluate areas of management). Whether or not this actually is the start of the much-touted counter-offensive will not be simple to say. Such an operation is just readily noticed if it succeeds, or fails spectacularly. Our information don’t but recommend a big Ukrainian advance, or beneficial properties of territory. Slightly, they’re in line with a power laying the groundwork for that to occur. Ukraine seems to be probing defences for weaknesses, and, by hanging command posts and logistics far behind the entrance line, lowering the flexibility of Russia’s forces to plug gaps.

The uptick within the variety of fires started on Could eleventh. There may be cause to consider that on the identical day Ukraine started utilizing Storm Shadow missiles, long-range weapons able to hanging fortified positions, which had been despatched by Britain. The typical variety of fires marked as war-related in Russian-held areas is at the moment on the highest since August 2nd 2022—greater than 100 per day. (These totals are solely a information to exercise: the satellites can’t register all fires and bigger ones could generally be recorded as a number of smaller ones.)

If and the place Ukrainian forces will advance will rely partially on what these stage-setting operations reveal about Russian defences. A strike within the south, maybe over the Dnipro river close to Kherson, is one choice, as it might endanger Russia’s management of Crimea. One other is a renewed push within the north, following up on previous advances eastward from Kharkiv. And, between the 2, Ukrainian forces are nonetheless combating, and making restricted advances, round Bakhmut (regardless of claims that the town has fallen to Russia). We’ve got detected exercise in all three areas previously week. A profitable strike south-east from Zaporizhia can be interesting, too. It could lower off the land bridge to Crimea and Russian forces west of Melitopol.

For a decisive breakthrough, shock shall be key. That may imply feints in a single location, to attract or pin down Russian forces, earlier than main strikes elsewhere. Wherever the thrust of the assault is perhaps, Ukrainian commanders will attempt to maintain their Russian counterparts, and the remainder of us, guessing what they may do subsequent.
