HMS Magpie (H130) is a Sea-class inshore hydrographic survey vessel of the Royal Navy, built by Safehaven Marine to a Wildcat 60 catamaran design and commissioned on 28 June 2018 as the direct replacement for the veteran HMS Gleaner. Displacing around 37 tonnes with a length of 18 metres, shallow draught of 1.35 metres, and high-speed capability, she is equipped with advanced multibeam sonar and sensors for mapping seabeds, ports, harbours, and coastal waterways inaccessible to larger survey ships. Based at HMNB Devonport as part of the Hydrographic Squadron, Magpie conducts critical inshore surveys to update nautical charts, support safe navigation for the fleet, and contribute to environmental monitoring. As of early 2026, she remains actively in service, continuing operations around UK waters and supporting the Royal Navy's hydrographic commitments.
