Norway’s military intelligence agency announced today that Russia’s test of its new long-range Burevestnik (“Sea Walker”) nuclear-powered cruise missile last week took place from the Novaya Zemlya archipelago in the Barents Sea.

“We can confirm that Russia conducted a test launch of the Skyfall (Burevestnik) long-range cruise missile from Newfoundland”Vice Admiral Nils Andreas Stensoens, head of Norway’s intelligence agency, said in an emailed statement to Reuters.

According to the briefing made by the Chief of the General Staff of the Russian National Defense Valery Gerasimov to President Vladimir Putin, the missile traveled a distance of 14,000 kilometers and was in the air for about 15 hours.

Putin has stated that the 9M730 Burevestnik missile is “invisible” to current and future missile defense systems, with an almost unlimited range and an unpredictable flight path.

The new nuclear-powered missile (SSC-X-9 Skyfall, according to the NATO code name) can carry a nuclear warhead.

In remarks yesterday, Putin, dressed in camouflage, told Gerasimov that critical tests of the Burevestnik had been completed and that work would begin on the final stage before the missiles were deployed.
