# Soviet naval reactors

Soviet naval reactors have been used to power both military and civilian vessels, including:
* Nuclear submarines:
** Attack submarines.
** Cruise missile submarines.
** Ballistic missile submarines.
* Nuclear icebreakers:
** Soviet icebreaker Lenin
** Arktika-class icebreakers
** Taymyr-class icebreakers
* Russian floating nuclear power stations:
** Akademik Lomonosov
* Nuclear cruisers:
** Kirov-class battlecruisers
* Merchant ship:
** Sevmorput
* Command ship:
** SSV-33 Ural
They have included both pressurized water reactors and a relatively few liquid metal fast reactors.
OKBM Afrikantov has been the primary designer of naval reactors for the Soviet/Russian Navy for more than 60 years.
