Satellite imagery shows Russia adapting submarine defences amid drone threats
Satellite imagery indicates that Russia is employing anti-drone grills and partial submersion to protect its Kalibr-capable submarines at the Novorossiysk naval base. These measures are intended to mitigate the threat posed by Ukrainian aerial drones to sensitive submarine components.
Why it matters
This highlights the evolving nature of naval warfare and the adaptation of traditional military assets to counter low-cost, high-impact drone technology.
New high-resolution satellite imagery shows Russia is using a combination of partial submersion and anti-drone structures to protect its Kalibr-capable submarines at the Novorossiysk naval base, according to Ukrainian defence outlet Defense Express.The imagery, released by the UK Ministry of Defence, shows three Russian Project 636.3 Varshavyanka-class diesel-electric submarines in Novorossiysk Bay. The submarines are among the platforms used by Russia to launch 3M14 Kalibr cruise missiles at targets in Ukraine.Two of the submarines moored inside the inner harbour are fitted with large anti-drone structures known as “grills” or “barbecues”, according to Defense Express, which analysed the satellite imagery.The submarines are also being kept partially submerged, with most of their hulls beneath the water while their upper structures and sails remain above the surface.According to Defense Express, the combination provides two layers of protection against Ukrainian drones.
