Ukraine’s army intelligence directorate, the GUR, has claimed duty for a severe hearth aboard a Russian warship on the port of Kaliningrad, 800 miles away from the primary battle within the Black Sea. 

In a social media assertion, the GUR claimed {that a} hearth broke out aboard the Buyan-M class corvette Serpukhov at Kaliningrad, the Russian exclave and naval base wedged between Poland and Lithuania. Russian sources haven’t confirmed the assault. 

GUR supplied what gave the impression to be a schematic of the vessel’s inner areas, and a short video of an incendiary system going off. The company stated that the Serpukhov sustained substantial injury from the hearth. “Its means of communication and automation were completely destroyed,” the GUR claimed. 

Serpukhov is the eighth vessel within the Buyan class and the fifth of the upgraded Buyan-M variant. These ships are designed for coastal operations and are closely armed for his or her measurement, carrying as much as eight Kalibr or Oniks antiship missiles and as much as eight surface-to-air missiles. 

The GUR’s declare couldn’t be confirmed, however it will be in step with the group’s current emphasis on deep strikes behind the Russian traces. The company’s drones have hit Russian oil refineries as much as 750 miles away from Ukraine’s borders, and have taken roughly 14 % of Russia’s refining capability offline. The newest strike – a claimed attack on a product pipeline – allegedly disabled all product tanker loadings on the occupied port of Azov. 

The GUR has additionally mounted a profitable marketing campaign in opposition to the Russian Black Sea Fleet, damaging or destroying a claimed one-third of its pressure and confining the remaining to the relative security of Novorossiysk. 

Serpukhov’s sister ship Velykyi Ustyug was doubtless broken by a Ukrainian drone early within the invasion. In June 2022 the Ustyug was photographed in tow to a shipyard, displaying indicators of fragmentation injury alongside her port aspect.
