Russia “Cages” Navy Vessel In Black Sea—What Is It Trying To Hide From Ukrainian Drones?

Russia has modified one of its Ministry of Defense research vessels with visible anti-drone protections in the Black Sea port of Novorossiysk, highlighting growing concerns over Ukrainian unmanned attacks at sea.

According to Defense Express on March 24, the vessel identified as Lagoda, a Project 11982 oceanographic research ship, was observed with newly installed protective structures during a public naval ceremony.

Footage of the event, which marked the anniversary of the launch of the submarine Veliky Novgorod, inadvertently revealed the ship alongside other vessels in port.

According to Defense Express, analysts noted the presence of multiple defensive additions on the Lagoda, including metal cage-like structures mounted around the bridge, camouflage netting across large sections of the deck, and a visible electronic warfare system.

OSINT analyst H I Sutton also drew attention to these modifications, suggesting they were specifically intended to counter Ukrainian drone strikes.

The vessel is officially designated for oceanographic research, search-and-rescue operations, and support missions. However, the extent of camouflage—particularly over the bow and deck access points—may indicate the presence of additional onboard equipment.

This could include radar systems or signals intelligence platforms, though it remains unclear whether the coverings are intended for concealment or purely defensive purposes.

Technical assessments cited by Defense Express indicate that the installed electronic warfare systems are likely effective against short-range FPV drones but have limited capability against drones guided via satellite communication links. This suggests that more advanced Ukrainian systems could still pose a threat.

Protective “cage” structures—commonly referred to as “cope cages”—may reduce the impact of smaller explosive drones by triggering detonation before direct contact with critical sections of the vessel. However, their effectiveness against larger unmanned systems carrying heavier payloads remains uncertain.

The outlet notes that Ukrainian maritime and aerial drones have increasingly used heavier warheads, with some systems reportedly carrying significantly larger explosive payloads than standard FPV platforms.

In such scenarios, structural add-ons alone may not provide sufficient protection for the crew or onboard systems.

According to Defense Express, similar Russian vessels have already been used beyond their declared research roles. In February 2026, a reconnaissance ship launched a drone toward the French aircraft carrier Charles de Gaulle near NATO waters, demonstrating the potential use of such platforms for surveillance and drone-based intelligence operations.

This context suggests that ships like Lagoda, despite their official designation, may also support military or reconnaissance activities at sea.

Earlier, Russia continued building its Project 23900 amphibious assault ship Ivan Rogov in occupied Kerch, with key structures already assembled, though timelines remain uncertain and the site is within range of Ukrainian strikes.
