A trial model of Russia's nuclear-capable outer space strategic bomber will be developed by 2020, according to its developer.
The engine is expected to be showcased at the Army-2016 International Military Technology Forum, which is set to take place on September 6-11 in the Moscow Region.
“The idea is that the bomber will take off from a normal home airfield to patrol Russian airspace. Upon command it will ascend into outer space, strike a target with nuclear warheads and then return to its home base,” Solodovnikov told RIA Novosti.
He added that the jet will be very capable and will need only one-two hours to reach any place on Earth through outer space.
“We are cooperating with Russia’s Central Aerohydrodynamic Institute on the design of an airframe and the aircraft's characteristics. I think that its lift-off mass must be 20-25 metric tons for it to be a strike aircraft. It will [be able to accelerate to] hypersonic speed in rocket mode," he added.
