The word “dreadnought” (or dreadnaught) dates back to the late 17th century, where it described a fearless warrior- one who dreaded naught. This moniker was later given to the first modern battleship of the early 20th century, the Royal Navy's HMS Dreadnought, one of the most fearsome naval warships in existence when launched in 1906. The HMS Dreadnought battleship featured the absolute latest in naval innovations of the time, namely a new steam turbine propulsion system, and unprecedented “all-big-gun” firepower, delivered by a plethora of heavy-caliber guns.
The Royal Navy will soon launch a new class of Nuclear Ballistic Missile Submarines (SSBNs) as the successor to its current Vanguard-Class subs, and in 2016 appropriately named it the Dreadnought-Class. Like its battleship namesake, the Dreadnought-Class of SSBNs will feature the cutting-edge of naval propulsion design, incredible firepower, as well as several features that will make it unique even among other modern submarines.
