MOSCOW (AP) — President Vladimir Putin says the Russian military will start receiving new nuclear weapons in the coming years.

Speaking at a meeting Friday in Sochi, Putin said delivery of the new Avangard hypersonic vehicle will begin next year while the new Sarmat intercontinental ballistic missile will enter duty in 2020.

The Avangard and the Sarmat were among an array of new nuclear weapons Putin presented in March. He noted that they can't be intercepted. They also included a nuclear-powered global range cruise missile and an underwater drone designed to strike coastal facilities with a heavy nuclear weapon.

Putin said two other new systems unveiled in March — the Kinzhal hypersonic missile and the laser weapon called — have already been put on duty with the units of Russia's Southern Military District.
