Russian Project 21980 boat fitted with anti-drone 'mangal' cage

The post shows a Russian Black Sea Fleet Project 21980 (Grachonok) patrol/anti-saboteur boat fitted with a metal cage/"mangal" style overhead protection intended to reduce damage from UAV/FPV attacks. While improvised cages are common on ground vehicles, adapting them to small naval craft is a notable field-expedient survivability measure with tradeoffs for seaworthiness and limited effectiveness against multi-aspect drone attacks.
