Ukraine’s military intelligence agency (HUR) said its special unit “Prymary” (Ghosts) struck high-value Russian naval assets and a radar system in occupied Crimea overnight, targeting capabilities used in Moscow’s war against Ukraine.
According to the HUR report, the operation took place the night of April 18-19 in Sevastopol Bay, where two large Russian landing ships from the Black Sea Fleet were hit and put out of action.

HUR identified the vessels as the Project 775 landing ship Yamal and the Project 1171 landing ship Nikolai Filchenkov. Both ships were in the harbor at the time of the strike.
The Yamal, commissioned in 1988, can carry up to 500 tons of cargo – including armored vehicles and troops – and is estimated to be worth more than $80 million. The Nikolai Filchenkov, built in 1975, has a capacity of up to 1,000 tons and can transport dozens of armored vehicles and a large landing force, with an estimated value exceeding $70 million.
In the same operation, Ukrainian intelligence said it destroyed a Russian Podlyot-K1radar system in occupied Sevastopol. The system, used for low-altitude target detection, is valued at approximately $5 million.
HUR published a video that it said shows the strikes on Russian targets in occupied Crimea. Kyiv Post could not independently verify the authenticity of the footage.
