“If a cyberattack happened to a missile system,” she explains, “that is the kind of consequence that we would see – the ballistic missile or the cruise missile going off from its route.”Īnother recent event with all the hallmarks of a hack took place on the morning of the 13 January this year, when every smartphone in the state of Hawaii suddenly displayed the message: “BALLISTIC MISSILE THREAT INBOUND TO HAWAII. While Downing Street claimed that the test had therefore been “successful”, the pattern of events were of the kind Dr Unal and her colleagues look for. The MoD’s explanation was that the missile (which did not contain nuclear warheads) was not faulty, but that it had been supplied with the wrong information the missile itself quickly recognised the mistake and self-destructed. “There were rumours about it,” she recalls. According to defence sources, the missile headed instead towards the mainland United States.ĭr Beyza Unal, a senior research fellow in the International Security Department at Chatham House, remembers discussing the malfunction with colleagues at the UN. HMS Vengeance, then submerged off the coast of Florida, released a missile programmed to head south-east across the Atlantic, crossing thousands of miles of unpopulated ocean to a point below the southern tip of Africa, but this did not happen. The last publicly known Trident missile test by the UK was in June 2016. The power of these engines is phenomenal in less than two minutes, the missile reaches 24 times the speed of sound, covering five miles a second. As soon as the missile senses that it has begun to fall back towards the waves, the first of its rocket engines ignites and it begins to climb into the air. This creates a sudden huge increase in pressure that pushes the missile – which weighs almost 60 tons and is one and a half times the length of a Routemaster bus – out of the submarine, up to the surface and a short distance into the air above the surface of the ocean. Inside the launch tube, an explosive charge vaporises a tank of water in a flash. The Trident II D5 missile is powered, in the first moment of its flight, by steam.
