Russia will soon be able to launch 12 Poseidon supertorpedoes at once.
On November 1, the launch ceremony for the Project 09851 nuclear-powered special-purpose submarine Khabarovsk took place at the Sevmash shipyard in Severodvinsk, Arkhangelsk Region. According to a communiqué from the Russian Ministry of Defense, the newly launched submarine is designed to fulfill the Russian Navy's missions "using modern naval underwater weapons, including robotic systems for various purposes," ensuring the security of Russia's maritime borders and protecting the country's national interests in various parts of the world's oceans.
It's worth noting that Khabarovsk is the second carrier of the 2M39 Poseidon unmanned underwater vehicles (NATO designation Kanyon, formerly known as Status-6), a strategic nuclear-powered carrier that carries nuclear warheads (nuclear torpedoes). This operation suggests that the Russian Navy will soon be able to simultaneously launch 12 Poseidon supertorpedoes, six from each submarine, if necessary.
The first Poseidon carrier, the Project 09852 special-purpose submarine BS-329 Belgorod, is currently based in Severodvinsk. The Khabarovsk, after completing trials and entering service, will likely be deployed to the Pacific Ocean.
It's worth noting that, unlike the Belgorod submarine, which was built using the existing Project 949A Antey SSGN hull, the Khabarovsk submarine was designed from scratch. The Khabarovsk's dimensions are quite modest compared to those of the Project 955A Borei-A and Project 949A Antey submarines, and comparable to the Project 885M Yasen-M.
