Amid rising tensions between Russia and the US and UK, Mr Putin told young recruits they had the military advantage – including a missile “absolutely invulnerable” to defence systems.
He told cadets this week they had nothing to fear from rival armies as the cold war with Europe and America continued to escalate.
Mr Putin said: “A number of our weapons systems are years and, perhaps, decades ahead of foreign analogs.
“Modern weapons contribute to a multifold increase in the Russian military potential.
“We have achieved a real breakthrough thanks to the colossal efforts by science and design bureaus and industries, a real feat by workers, engineers and scientists.”
He highlighted the hypersonic Avangard missile as particular cause for concern for enemy leader, boasting it can fly 20 times the speed of sound.
He said: “It is absolutely invulnerable to any air or missile defence means.”
Earlier this week it was revealed plans for a huge Cold War-era nuclear-tipped torpedo was being “reviewed”.
Shamil Aliyev regarded as Russia’s top modern-day missile designer, confirmed the review – but warned he believed the terrifying weapon was “absolutely unconscionable”.
The 75-year-old, who is now a well-known disarmament campaigner, said: “There is a general tendency of reviewing the ideas that were not implemented before.
“Sakharov’s ideas about making 24-meter-long nuclear-tipped torpedoes with a 1.5-meter diameter – and a 50-kilometre range – are being reviewed.”
The project, which was codenamed T-15, aimed to “destroy coastal targets via aquatic explosion” by triggering a monumental tsunami.
And earlier this year Putin also revealed plans for missions to Mars – including manned operations.
He said in March: “We are planning unmanned and later manned launches – into deep space, as part of a lunar program and for Mars exploration.
“The closest mission is very soon, we are planning to launch a mission to Mars in 2019.
“Our specialists will try landing near the poles because there are reasons to expect water there.
“There is research to be done there, and from that, research of other planets and outer space can be undertaken.”
