Russian President Vladimir Putin flew on a nuclear-capable strategic bomber on Thursday, in a likely move to flaunt Russia’s nuclear capabilities in defiance of the West.

Moscow said Putin took a brief flight on a modernized Tu-160M bomber, codenamed “Blackjacks” by NATO.

State media showed Putin, 71, taking off in the giant plane from a runway belonging to the factory in Kazan, which makes the supersonic aircraft.

The plane landed less than an hour later, Russian news agency TASS reported. Moscow did not provide specifics on its flight path, which is considered a military secret, according to Kremlin spokesman Dmitry Peskov.

The giant swing-wing plane is a modernized version of a Cold War-era bomber owned by the former Soviet Union. While it was not used during the conflict, it would have deployed to deliver weapons at long distances, Reuters reported.

The Tu-160M is capable of carrying 12 cruise missiles or 12 short-range nuclear missiles and can fly approximately 7,500 miles without needing to refuel. It has just four crew members. In 2005, the Russian president flew inside another version of the aircraft.

Russia signed a contract in 2018, to purchase 10 modernized Tu-160M nuclear bombers. They are expected to be delivered to the Russian Air Force by 2027.
