A Russian bomber capable of flying for 30 hours straight will be in the skies by 2027, the country has claimed.
Deputy defence minister, Aleksey Krivoruchko, said the PAK DA aircraft comes as part of a major military investment spree.
The plane can reportedly fly for more than a whole day straight.
It was produced by Russian aircraft manufacturer Tupolev and can operate in stealth mode, reports add.
The move comes as Vladimir Putin's state also prepares to launch submarines.
Krivoruchko said: "Under the state arms program, units of modern military and special equipment, which are not inferior to the best foreign analogues and often have no analogues in the world, will enter operational service in the period until 2027.
Borei-A strategic missile submarines, the Prospective Aviation Complex of Long-Range Aviation, and strategic missile systems – both fixed and mobile – will enter operational service with the strategic nuclear forces."
Mass production of the bomber could start in 2028, the nation previously said.
Earlier this week it was announced Russia was set to launch a new hypersonic nuclear missile that strikes enemies "like a meteorite".
The Avangard missile can strike anywhere in the world in less than 30 minutes, it is claimed.
The commander of Russian Strategic Missile Forces (RVSN) Colonel-General Sergey Karakaev told Red Star newspaper today: "The deployment of the first rocket regiment with the Avangard missile system at the Dombarovksaya Rocket Division is planned by the end of 2019."
It comes a year after Putin said: “On my instructions, the Ministry of Defence prepared and conducted a final test of this system. This has just been completed with absolute success.”
