Vladimir Putin has said that Russia will deploy its new Sarmat intercontinental ballistic missile, nicknamed 'Satan 2', as well as roll out hypersonic missiles and new nuclear submarines. The missiles were supposed to have been deployed last year. 
The Russian leader, who has in recent days signalled he is ready to rip up the architecture of nuclear arms control, invoked the Soviet victory over Nazi Germany to argue that Russia needed modernised armed forces to guarantee its sovereignty. It comes after he said Russia would halt its participation in New Start, the last remaining major nuclear arms control treaty with the US
