Malfunction Occurs on Nuclear-Powered Submarine with Nuclear Weapons

According to the BBC, an unnamed nuclear submarine belonging to the Royal Navy experienced a worrying malfunction while diving over a year ago. The submarine is a Vanguard class vessel, which carries the UK's trident nuclear missiles, and the incident occurred during its preparations for a patrol. A defence source has mentioned that the problem was concerning, but it was detected by the submarine's system. The Royal Navy conducted an investigation into the incident, but no further specifics were provided. Although the main depth gauge failed during the incident, a secondary gauge continued to function. It is essential for submarines to withstand immense pressure during dives, and redundancy systems are incorporated in nuclear-armed submarines to prevent the escalation of any issues. Details of the incident were initially disclosed by the Sun newspaper, stating that engineers on board alerted the crew to the failure while the submarine was diving. The newspaper added that the submarine was still operating within safe limits but was approaching its "crush depth" before the alarm was raised. The Ministry of Defence typically refrains from commenting on submarine operations. The Royal Navy has ensured that its submarines are fulfilling their obligations and that the safety of its personnel is their top priority. The Vanguard submarines are stationed in Faslane, Scotland, and typically have a crew of 132 officers and men. Earlier this year, a "defect" was discovered during maintenance work on HMS Vanguard, the lead boat of the Vanguard-class submarines, which was promptly repaired. In May, the vessel completed a seven-and-a-half-year refit at the Devonport dockyard.
