Imperial fortress in the context of "Royal Navy Dockyard"

The Royal Navy (RN) is the naval warfare force of the United Kingdom, responsible for defending the UK, the Crown Dependencies, and the Overseas Territories from naval attack or invasion. It is a component of His Majesty's Naval Service, and its officers hold their commissions from the King. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service.

From the early 18th century until the Second World War, it was the world's most powerful navy. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority. Following World War I, it was significantly reduced in size. During the Cold War, the Royal Navy transformed into a primarily anti-submarine force, hunting for Soviet submarines and mostly active in the GIUK gap. Following the collapse of the Soviet Union, its focus returned to expeditionary operations.

The military history of the United Kingdom covers the period from the creation of the united Kingdom of Great Britain, with the political union of England and Scotland in 1707, to the present day.

From the 18th century onwards, with the expansion of the British Empire and the country's industrial strength, the British military became one of the most powerful and technologically advanced militaries in Europe and the world. Scottish regiments and in particular Highland regiments, made a significant contribution to the military expansion, history and maintenance of the British Empire in the 19th and 20th centuries. The Royal navy in particular, with major bases in four Imperial fortresses and coaling stations surrounding the globe, was the world's greatest naval force from the 18th to the mid-20th century. British military declined in the mid-20th century as did those of the traditional European continental powers following the two world wars, decolonisation, and the rise of the United States and the Soviet Union as the new superpowers. However, Britain remains a major military power with frequent military interventions around the world since the end of the Cold War in 1991. The present-day British Armed Forces encompass the Royal Navy, the British Army, and the Royal Air Force.

Following a projected £2 billion overspend acknowledged by the MOD in 2025, the Royal Navy announced it will reduce overseas training in the Indo-Pacific and the Middle East.

Admiralty House, Bermuda, was the official residence and offices for the senior officer of the Royal Navy in the Imperial fortress colony of Bermuda, originally the Commander-in-Chief of the North America and West Indies Station.
