It is feared to have a range of 6,200 miles with top speeds of up to 56 knots

Russia has tested a terrifying new 'drone' submarine capable of carrying nuclear warheads unmanned within range of the US, it has emerged.
The top-secret nuclear-capable sub, code-named Kanyon by the Pentagon, is feared to have a range of up to 6,200 miles with top speeds of56 knots.
US security officials detected the test on November 27 after it was launched from a separate Sarov-class submarinethough the location has not been revealed.
It comes after pictures emerged ofVladimir Putin's 50ft underwater 'robot' that can imitate any submarine in the world and carry out 600-mile spying missions 1,800ft below the surface.
Russian military designers say their 'submarine imitator', called Surrogat, will be capable of travelling at speeds of up to 24 knots for hours on end.
Powered by lithium-ion battery, it will be able to imitate both conventional and nuclear-powered submarines thanks to its 'modular design' which allows it to 'change its functionality'.
