The Sea-class workboat has been procured for Britain's Royal Navy to undertake a number of roles, including: logistics and transport tasks, inshore and harbour survey work, diver training and support, officer training and providing passenger transfer modules for the aircraft carrier HMS Prince of Wales. An autonomous minehunting variant of the class has also been procured.
A procurement contract for £48M was awarded to Atlas Elektronik UK (AEUK) in September 2017 for the delivery of up to 38 vessels under the program. Thirty-five vessels were ultimately built, with deliveries beginning in 2018 and completing in 2024. All vessels, with the exception of HMS Magpie (the largest boat in the series), are non-commissioned assets within the Royal Navy.[3]
