Water (and air) will not form radioisotopes suitable for radiological warfare when neutron activated, however the seawater-salt will, and the seabed may. Much of the radioactivity will be deposited in the sea, and be carried by ocean currents. Unless the detonation happens at low depths in shallow waters, an underwater detonation will have its fallout greatly reduced, except for at the surface immediately above, near the base surge. Normal (not salted) thermonuclear weapons cause radioactive fallout primarily through neutron activation of material at the detonation site. The Poseidon could be a radiological second strike weapon. For this purpose, the Poseidon is speculated to be equipped with a cobalt bomb. The Poseidon warhead can contaminate a large area with radiation.

missile defense systems, : 25 such as anti-ballistic missiles, etc. withdrawal from the ABM treaty and to increase the Russian capability to overcome the U.S. The Poseidon is intended to serve as response to U.S. Design speculation Overview Įstimated diameter of the Poseidon, about 2 meters On 16 January 2023, it was reported that the first batch of the weapons has been manufactured. On 20 February 2019, the Russian Defence Ministry released a video, showing a Poseidon being test-launched by a B-90 Sarov special purpose submarine. On 2 February 2019, Russian President Vladimir Putin announced completion of the key stage of trials of Poseidon. In January 2019, the Russian Navy announced plans to procure at least 30 Poseidon unmanned underwater vehicles, deployed on four submarines, two of which would serve in the Russian Northern Fleet and two in the Pacific Fleet. In March 2018, the system was officially named "Poseidon", following a public vote. In early 2018, the Pentagon's Nuclear Posture Review publicly acknowledged development of Russia's "new intercontinental, nuclear armed, nuclear-powered, undersea autonomous torpedo". The test was reportedly carried out in the Arctic Ocean. Īccording to the Pentagon, Russia conducted the first test-launch of Poseidon on 27 November 2016, using the B-90 Sarov special purpose submarine. The CIA has claimed the leak was intentional. Speculation arose as to whether this was a warning signal or disinformation intended to mislead foreign intelligence services. The leak happened during Russian President Vladimir Putin's speech denouncing American plans concerning defensive missile technology.

On 10 November 2015, a page of a document that contained information about a secret "oceanic multi-purpose system" called "Status-6" was "accidentally" revealed by Russian NTV television channel. The first public appearance of Poseidon dates back to September 2015 and cites Pentagon sources. The Poseidon is one of the six new Russian strategic weapons announced by Russian President Vladimir Putin on 1 March 2018. The Poseidon ( Russian: Посейдон, " Poseidon", NATO reporting name Kanyon), previously known by Russian codename Status-6 ( Russian: Статус-6), is an autonomous, nuclear-powered unmanned underwater vehicle reportedly in production by Rubin Design Bureau, capable of delivering both conventional and nuclear warheads.
