Alexandr Rumyantsev made an interesting proposal - if you have an old nuclear submarine, bring it to Russia. We will dismantle it for you and find a place to store its reactor compartment.

But why stop here? Russia could provide complete service - we'll build a submarine for you, equip it with missiles and crews and operate it wherever you chose. We would even help you target the missiles (extra fee for targets on Russian territory). Just let us know...
