The War Zone column from the Drive.com blog recently featured photographs of a Royal Navy Vanguard class submarine returning to HM Naval Base Clyde, which is also known as Faslane, on the west coast of Scotland, after a 197-day nuclear deterrent patrol. The nuclear ballistic missile sub looked like what they describe as a “sea monster that had emerged from a long slumber at the bottom of the ocean.” The hull is indeed covered by an impressive growth of marine fouling.
Of course, the mission of ballistic missile submarines, often referred to as “boomers,” is to serve as undetectable launch platforms for intercontinental missiles, which is to say that their job is to go find a place to hide in the ocean for extended periods of time. The opportunity to keep the hull free of maritime growth is, at best, limited, even with the latest anti-fouling coatings now available.
