Belgorod, set to be the largest submarine in the world, was first reported in 2017. It was initially expected to be used on research missions, however, it has now been claimed that it will have six deep-sea nuclear warheads attached. Named “Poseidon”, the 70ft underwater drones are reportedly powered by a small nuclear reactor and can function at a depth of 1,000 metres.
Last week, Defence Minister Sergey Shoigu said the plan is to deploy the submarine from Severodvinsk yard, in northern Russia, before summer 2019.
This will then reportedly be followed by a year of testing, before Belgorod enters active duty in 2020.
Mr Shoigu told Russian daily newspaper Kommersant: “The whole complex of works should be completed this year.
“These ships will determine the future appearance of our submarine fleet.
