The Royal Navy's newest submarine, HMS Astute, has blasted Tomahawk missiles far across the North American skies, as part of its first test firing mission. Pictures show the Tomahawk weapons, which rocketed from HMS Astute at up to 550 miles per hour (885kph) across the Gulf of Mexico. The 5.5-metre-long cruise missile weighs 1,300kg and has a range of more than 1,000 miles.
