This missile systems are created on the basis of previous Russian design projects that have been finalized, the president said, adding that he took part in the decision to produce Oreshnik.
"This [Oreshnik] is a modern, very new weapon," Putin said at the annual "Direct Line" question-and-answer session combined with his end-of-year press conference.
When asked why Oreshnik got its name, Putin said that he does not know.
