New reports suggest Russia is developing a first of its kind hypersonic stealth nuclear bomber which can launch nuclear missiles in the space. The hypersonic PAK-DA strategic bomber will be fast enough to travel anywhere in the world within two hours of time.

The prototype of the bomber aircraft is currently under development and is expected to be ready to take flight in 2020, following successful engine tests. The PAK-DA test engine is expected to get exhibited at the International Military Technology Forum "Army 2016" which is scheduled to be held in Moscow from September 6 to September 11.

Commenting on the development, Colonel General Sergei Karakayev, commander of Russian Strategic Missile Forces, said that a model engine for the aircraft has already been built and tested at the Serpukhovo branch of the Military Academy, reported Science Alert.

According to the Strategic Missile Forces Academy, the engine of the PAK-DA strategic bomber plane will operate in two modes. When flying inside the earth's atmosphere, the engine will burn kerosene fuel, while it will switch to methane and oxygen on entering space.
