In August 2017, the replacement for HMS Gleaner, the Royal Navy's existing inshore survey launch, was announced to be one of a total of 38 multi-role workboats of various sizes being constructed to undertake various duties. The main structure of the vessel was constructed by Safehaven Marine, a boatbuilding company based in Cork.[2] In February 2018, it was announced that the ship would be named HMS Magpie.[3] The type selected for the inshore survey vessel was based on Safehaven's Wildcat 60 catamaran design, the largest available at 18m in length, and with a displacement of 37 tonnes. Magpie was built to accommodate a crew of 12 for up to seven days, with the capability of operating in all weathers. Following completion and initial trials by Safehaven Marine, Magpie was subsequently delivered to Atlas Elektronik UK (AEUK) for installation of its mission equipment. In April 2018, Magpie underwent further trials with its mission equipment installed,[4] before final delivery of the vessel to the Royal Navy in May 2018 for commissioning in early summer.[5]
Magpie was procured under "Project Vahana", a programme to acquire up to 38 smaller boats in order to replace various Royal Navy vessels under 20 metres in length. The boats are known as the Sea-class and Magpie, at 18 metres in length, is the largest and only commissioned vessel in the series.[6]
As Magpie is considerably larger than the vessel she replaces, the title of smallest commissioned vessel in the Royal Navy, which had belonged to Gleaner, initially passed to the two
One of Magpie's first major taskings was a continuation of work done by her predecessor Gleaner in surveying Portsmouth Harbour to ensure the stability of the seabed in anticipation of Portsmouth's use by the aircraft carriers and .[7]
Once the work in Portsmouth harbour is complete, Magpie was tasked to survey the wreck site of the Mary Rose, Henry VIIIs flagship, to search for anything of significance.[8]
Work then focused on investigating the wreck of a French galley which was lost off the north-east coast of the Isle of Wight around the same time as the Mary Rose.
