The second Russian Navy submarine to serve as a basic carrier of the Poseidon nuclear-capable underwater drone will be floated out in late June, the state media reported. The Khabarovsk will reportedly be able to carry up to six Poseidon unmanned underwater vehicles (UUVs).


"The Khabarovsk [Project 09852] will be floated out in late June at the earliest. There is no exact date so far," a source from the Russian defense industry told TASS.


Naval News, with data from Covert Shores, has described the new submarine as similar but smaller than the Project 955 "Borei" SSBN. The estimated length of the new submarine is about 120 meters compared to the 160 meters for the BOREI. In addition, it was noted that it is even possible that the submarines may share many components and even hull sections.

Khabarovsk, the lead boat of the Project 09851, is the first of four planned nuclear-powered submarines and it was laid down in 2014 with plans for it to be launched this year. The Khabarovsk-class boats should be capable of carrying weapons such as torpedoes, anti-ship and land attack missiles—and as these will be fitted with a nuclear reactor and pumpjet propulsion system should have unlimited range, while sea endurance will be limited only by food supplies.

The Poseidon is a unique UUV with a nuclear propulsion system and nuclear warhead, and it can operate as an autonomous nuclear torpedo with a nearly unlimited range. The Pentagon reports confirmed the existence of the UUV in 2016. It can reportedly carry a nuclear warhead with a blast yield of two megatons (MT), and it can reach underwater speeds of 108 knots—significantly faster than traditional torpedoes.
