Size-wise, the Trident is a little larger than a Microsoft Xbox One or a Sony PlayStation 4. The 13.6x9.2-inch chassis is easy to fit on a shelf or in a TV cabinet, as itâs just 2.8 inches tall when lying down.
Trident is the UKâs nuclear deterrent, and has been in place since the 1980s when it replaced Britainâs original Polaris missile system from the 1960s. It consists of four submarines each carrying missiles and nuclear warheads, to be deployed at a couple of daysâ notice in the event of the UK being attacked by nuclear weapons.
