The Multi Purpose Offshore Vessel RFA Proteus is a new addition to the Royal Fleet Auxiliary added this year in response to increased concerns about Russian attacks on submarine cables and other underwater infrastructure. The threat was heightened by the sabotaging the Nordstream pipelines in the Baltic Sea last September.
The ship was built in 2019
