The Royal Navy wants three new-build mine hunting motherships
It has emerged that the RN plans to acquire up to three ‘survivable, non-complex warships’ designed from the outset to be motherships for autonomous mine-hunting boats.
Main difference between Royal Navy MHC and France/Belgium/Netherlands is a craving for above all, SPACE. Room to carry more/larger USVs, prospectively (2 now, hopefully 3 in near future), ROVs, UUVs/AUVs, etc. The less space constraints, the better. It's the best future-proofing.
Ships being built for Belgium/Netherlands/France are brilliant little ships perfectly designed against the MCM system as is now. But space lets you adapt to how it will be tomorrow. Also, more room for NAVYPODs to bring aboard anything from better defence weapons to more drones.
