The Russian military’s new Zircon missile will reportedly be able to travel at five to six times the speed of sound, using a state of the art engine called a "scramjet".
Naval sources fear it would have a devastating impact on any ship it strikes.
Tim Ripley, defence analyst at Jane's Defence Weekly, told 5 live’s Phil Williams that for “the past 25 years the West has had military supremacy”, but now “the Russians are developing very potent weapons”.
He warns the UK could be “dead meat” if it doesn’t keep up.
