Putin presented Russia's military efforts as a response to actions by the United States, which last month unveiled plans to revamp its own nuclear arsenal and develop new low-yield atomic weapons.
Although Putin said his announcement was meant to get the attention of the USA, he also said he was open to talks with Washington.
The Trump Administration has vowed to expand U.S. nuclear strength, while criticising Russia's buildup.
According to the documents released in 2015, the Status-6 could carry a multi-megaton nuclear bomb with a range of about 10,000 kilometres moving at 56 knots, or 104 km/h and travel to a depth of more than 1,000 metres. Its "very big" operational depth and a speed that is many times faster than any other vessel would make it immune to being intercepted by the enemy, he added.
Robert Schmucker, a rocket scientist at the Technical University of Munich, voiced skepticism about Putin's statement, saying in an interview that building nuclear-powered cruise missiles in particular would be technically hard and basically pointless. "Our system defends against ballistic missiles from outside the Euro-Atlantic area", Lungescu said.

Kelly's interview arrives as Putin rattled a sabre about Russia's nuclear capabilities, warning the West that his country's new intercontinental ballistic missile can evade any sort of detection and strike anywhere. We do not want a new Cold War or a new arms race.
Russian Federation has also dismissed allegations made by the United States of violating arms control treaties that were signed in the Cold War.
"It was certainly unfortunate to have watched the video animation that depicted a nuclear attack on the United States", State Department spokeswoman Heather Nauert said to the press. "This is the opposite of reduction, it's the opposite of a new start and any kind of arms control".
