The United Kingdom has deployed three of the four submarines that make up its nuclear deterrent force in the depths of the oceans.
The move has been described as unusual by Royal Navy sources, quoted by the British newspaper The Times.
As per usual practice, Britain keeps two submarines at sea: one armed with nuclear warheads and another on a training mission.
Currently, however, three of the four Vanguard nuclear submarines are at sea. At least one of them is equipped with Trident nuclear missiles.
Military experts warn that this deployment should not necessarily be interpreted as a threat to Russia or as a sign of an imminent dangerous development.
However, the move comes at a time when British authorities have increased their statements about preparedness for possible crisis and conflict scenarios.
Last week, British Defense Secretary Wes Streeting urged citizens to prepare for emergencies, including cyberattacks and terrorist acts instigated by hostile powers. Meanwhile, the Chief of the General Staff urged soldiers to be ready for a possible war.
Also last week, the British and French air forces conducted an exercise simulating a nuclear attack on an opposing country.
Britain's nuclear strategy
The UK has a policy of maintaining at least one nuclear submarine on constant patrol. The aim is to guarantee the ability to respond with nuclear weapons even if the country were to suffer a devastating attack.
This system forms the core of Britain's nuclear deterrence strategy: submarines can remain hidden underwater and maintain the possibility of a counterstrike.
Unlike Russia, which also possesses tactical nuclear weapons, the British arsenal relies on a sea-based deterrent force, without a separate category of tactical or battlefield nuclear weapons.
The British fleet consists of nine submarines: five of the Astute class, designed for conventional attack missions, and four of the Vanguard class, equipped with Trident ballistic missiles and tasked with nuclear deterrence.
The deployment of three of the four Vanguard submarines at the same time remains an unusual development, but without further official information it cannot be determined whether it is related to a specific threat or to operational circumstances of the fleet.
