Ukrainian intelligence has obtained secret documentation about Russia's newest nuclear submarine

Specialists of the Main Intelligence Directorate of the Ministry of Defense of Ukraine have gained access to classified materials related to Russia's strategic nuclear submarine — K-555 "Knyaz Pozharsky", project 955A "Borei-A".

Among the documents received:

• name lists of the submarine crew, including data on positions, qualifications and level of physical training;

• combat instructions for the crew;

• combat scheme of the ship, schemes of systems ensuring survivability and organizational structure of the crew;

• crew regulations in cabins and cockpits, instructions for transferring wounded and cargo, procedures for towing, and other job descriptions;

• engineering documentation, in particular, a report on the investigation of a deformed radio beacon indicating the members of the commission and the enterprises that participated in the investigation.

In addition, the GUR received an extract from the submarine's ship's schedule book, which regulates the daily order of service.

The Borei-A submarines are part of the Russian nuclear triad. Each vessel has 16 launch pods for R-30 Bulava-30 missiles, capable of carrying 10 warheads each.

"Knyaz Pozharsky" was officially commissioned into the 31st division of the Russian Northern Fleet on July 24, 2025 and is based in Gadzhievo, Murmansk Region. It was personally sent on combat duty by Vladimir Putin.

According to military intelligence estimates, the documents obtained allow us to analyze the technical features not only of this submarine, but also of other Project 955A units that are of strategic importance for the Russian military doctrine.
