Russian patrol plane near a carrier group
On 2 July, a Russian patrol plane — a Tu-142 Bear-F maritime patrol aircraft — repeatedly approached the British Carrier Strike Group during Operation Firecrest in the Norwegian Sea. It flew low and unnecessarily close to HMS Prince of Wales, then released numerous sonobuoys — underwater listening devices used to detect submarines. The UK Ministry of Defence called the activity unsafe and unprofessional. Two F-35B jets launched from the carrier intercepted and escorted the aircraft from the area.
A maritime-security incident in the High North
The episode centred on maritime surveillance and anti-submarine warfare, not only an air intercept. Sonobuoys add an underwater dimension in waters where NATO and Russia closely monitor submarine activity. HMS Prince of Wales is deployed near Iceland under NATO command with HMS Duncan and RFA Tidespring. Its F-35Bs are conducting NATO air-policing missions from a European carrier for the first time.
The incident shows pressure on carrier groups in the High North. More than 1,500 British personnel serve with the UK group as NATO strengthens surveillance through missions including Arctic Sentry. Protecting naval formations, sea lanes and underwater infrastructure is central to security in the Norwegian Sea and wider North Atlantic.
