Living for Weeks at the Bottom of the Sea Can Affect the Biological Clock of Anyone. So, the Most Advanced Nuclear Submarine Ever Built Will Have Technology Capable of Simulating the Day and Night Cycle
The United Kingdom has taken another step to renew its fleet of nuclear submarines. On March 20, a symbolic ceremony marked the official start of the construction of the HMS Dreadnought, considered the most advanced submarine in the world.
The event took place at the BAE Systems shipyard, nearly ten years after the first steel was cut for the vessel.
The HMS Dreadnought inaugurates a new class of British nuclear submarines. It will be one of the most powerful weapons ever built by the country. With a length of 153 meters, equivalent to 14 buses lined up, the submarine will be able to accommodate up to 130 crew members.

From empty land to a high-end house, wooden construction uses a lightweight system, metal structure for the foundation, ventilated ceramic cladding, and special windows to create an efficient and comfortable living space throughout the year.
The Technology of a Submerged Giant
The Dreadnought will be powered by a Rolls-Royce PWR3 nuclear reactor. It will also feature a turboelectric propulsion system and a pump-jet.
Being nuclear, it will be able to remain at sea for an unlimited time. The only limits will be the food supply and the crew’s endurance.
The vessel displaces 17,000 tons and will be armed with 12 Trident II D5 ballistic missiles. Each can carry up to 12 nuclear warheads, totaling 144 warheads on board.
Additionally, it will have four heavy Spearfish torpedoes and other weapons that were not disclosed.
But the Dreadnought is not only notable for its strength. It brings important innovations in comfort and onboard technology.
Innovations for Life Aboard
For the first time, a Royal Navy submarine will have separate accommodations for men and women. Bathrooms will also be divided, which is unprecedented on vessels of this type. This change marks a significant advancement in inclusion and crew well-being.
Another differentiator is the lighting. The Dreadnought will use an adaptable system that mimics the day and night cycle. This should help maintain the crew’s routine closer to life on land. The lighting will be adjusted in areas such as the infirmary, classrooms, and exercise spaces.
The vessel will also feature a control system inspired by aviation. Called Active Vehicle Control Management (AVCM), it will be responsible for regulating the course, depth, angle, and buoyancy of the submarine. Technical details of this system, however, have not been disclosed.
A Name with History
The HMS Dreadnought is the 12th British submarine to bear this name. It will be the first of a series of four vessels. The other three will be named HMS Valiant, HMS Warspite, and HMS King George VI.
The expectation is that the Dreadnought will enter service at the beginning of the next decade. It is anticipated to fulfill its missions for at least 30 years.
Until then, it will continue to symbolize the British effort to maintain a modern and efficient fleet in times of rapid technological changes and growing military demands.
