12 Jul 2023: Russia is attempting to hide important warships in the Black Sea by painting them in a new deceptive camouflage scheme, making it difficult to judge their length and shape in satellite imagery. Initial checks in some satellite images confirmed the viability of the camouflage. Imagery analysts have begun using artificial intelligence (AI) to identify classes of ships in radar (SAR) satellite imagery, an approach unaffected by the camouflage.

Reports of the new camouflage scheme emerged in late-June 2023. The flagship of the Black Sea Fleet, Admiral Grigorovich-class frigate Admiral Makarov, has had a more extreme camouflage applied. This includes ‘blacking out’ the helipad and the bow of the ship. Further, all three of Buyan-M class missile corvettes, the minesweeper Ivan Golubets and the anti-submarine corvette Muromets, have the camo.

– The camouflage is intended to hide the overall length and form of the ship when viewed from the surface, such as by a maritime drone. However the larger factor is likely from above: intending to make it harder to identify the ship in satellite imagery.

-AI is used with many electro-optical satellite images to determine a ship’s identity through length and shape. Such auto-identification may be more vulnerable to these types of camouflage than a human imagery analyst.

– Additionally, AI trained on SAR imagery was able to recognize distinct classes of warships and submarines with over 90 percent accuracy.

-Combining SAR images from an Umbra Space commercial satellite with AI from Satim Inc clearly identified ships known via other sources to have the new Russian camo scheme.

Combined with other satellite imagery and other forms of open source intelligence (OSINT), AI interpretation of SAR imagery can help unmask the camouflaged ships.

Russia will likely continue to experiment with efforts to deceive satellite monitoring. Last year, the Russian Navy attempted to disrupt imaging of ports and bridges by placing barges with radar reflectors nearby. This is generally agreed to have not worked, and Russia abandoned the practice.
