The Admiral Grigorovich is a Project Burevestnik-class frigate and one of the key missile platforms in Russia’s naval fleet. It is armed with eight Kalibr cruise missiles and supported by a Shtil-1 air defense system capable of launching up to 24 missiles. Despite these defensive capabilities, Ukrainian drones were able to reach and strike the vessel.

In parallel with the attack on the frigate, Ukrainian forces also reported hitting the Sivash jack-up drilling platform. The strike was conducted jointly by the Unmanned Systems Forces and Ukrainian naval deep-strike units, indicating a coordinated effort against both military and infrastructure targets.

The incident follows reports from Russian authorities and local social media channels about a drone assault on Novorossiysk on the evening of April 5. According to the Telegram channel Astra, the Sheskharis oil terminal may also have been among the sites targeted during the operation.
