Algae-Covered Vanguard Submarine Returns from Lengthy Patrol

Images of a Royal Navy Vanguard class nuclear-powered ballistic missile submarine (SSBN) returning from a six-month-long deterrent patrol reveal the extensive marine fouling and rust that accumulates on submarines during long deployments. The submarine's hull is covered in a brownish-green hue, and many anechoic tiles designed to absorb sound waves are missing, indicating the wear and tear of the mission. Concerns have been raised about the safety and morale implications of extended submarine patrols, as crews face boredom and complacency. The Royal Navy is currently replacing the Vanguard class submarines with the Dreadnought class.
