A Spanish Guardia Civil vessel reportedly came close to a British nuclear submarine entering Gibraltar, drawing criticism and underscoring ongoing maritime friction.
Executive Summary:
A Spanish Guardia Civil vessel reportedly made a close, hazardous approach to the British nuclear-powered submarine HMS Anson as it entered Gibraltar on May 14, officials and observers said. The incident draws attention to recurring tensions over waters around the British Overseas Territory amid longstanding sovereignty disputes.
British Report Spanish Vessel ‘Dangerous’ Close To Submarine At Gibraltar
The Royal Navy’s latest port call in Gibraltar was overshadowed by a reported close approach by a Spanish Guardia Civil patrol vessel to the British nuclear-powered attack submarine HMS Anson, according to observers and social media posts.
Images shared locally show a fast patrol craft moving near the funnel of HMS Anson while the submarine was being escorted into Gibraltar harbour by tugs and Royal Navy Police craft. One Gibraltar-based observer described the vessel’s proximity to the security cordon and near the harbour wall as “reckless, unprofessional, dangerous.”
King’s Harbour Master Gibraltar, the port authority responsible for the harbour and surrounding waters, maintains strict safety zones around visiting warships, including submarines, to protect crew and port infrastructure. Any vessel breaching these security perimeters would be taken seriously by harbour and Royal Navy authorities.
Incident In Context Of UK-Spain Maritime Friction
The episode comes amid persistent friction between British and Spanish authorities over sovereignty and maritime rights around Gibraltar. Spain does not recognise British jurisdiction over the surrounding waters, and confrontations or close approaches by Spanish vessels have been reported repeatedly in recent years.
British protest notes and diplomatic demarches have followed earlier incursions and disputes. In other reported cases, Spanish authorities have countered that their patrols operate within waters they consider Spanish, reflecting the unresolved territorial dispute stemming from historical claims.
Strategic Significance Of Gibraltar Port Calls
Gibraltar continues to serve as a key anchorage and staging point for allied submarines and surface vessels transiting between the Atlantic and Mediterranean. Just days earlier the U.S. Navy’s Ohio-class ballistic missile submarine made a port call at Gibraltar without incident, illustrating the territory’s strategic role.
The presence of a contemporary Royal Navy nuclear submarine reinforces Gibraltar’s importance for NATO operations and underlines the need for clear protocols and respect for security zones when submarines enter and exit harbour.
Safety And Diplomatic Implications
Submarines, particularly nuclear-powered attack boats like HMS Anson, demand rigorous safety measures during harbour movements. Unauthorised approaches by fast patrol vessels can pose risks to personnel and equipment, and carry diplomatic weight in an already sensitive environment.
The United Kingdom Ministry of Defence and Gibraltar government had not issued statements at the time of reporting, leaving open questions about formal protest or follow-up measures.
