Then Dmitry Medvedev, the deputy chairman of Russia's Security Council, provided fresh warnings Thursday on the heels of Putin's nuclear threats that "Hypersound [hypersonic weapons] will be able to reach targets in Europe and in the United States much faster, guaranteed." 

Now there's word that Russian state-owned defense corporation Rostec will increase production of Su-57 5th-generation stealth fighter jets. 

"The Russian Air Force will receive new Su-57 jet fighters this year," Rostec head Sergey Chemezov said on the company's Telegram channel. 

Chemezov said the "production speed" of the stealth fighter jets "will be increased." He said the plant is based in Russia's Far East and is undergoing expansion to ramp up output.
