It further explains the principles that underpin the way in which UK maritime forces operate to offer scalable and responsive options, without commitment, to our government in support of our national interest.

This publication: defines maritime power; explains the attributes of maritime forces; explains the use of maritime power through the concept of sea control and the principles of maritime manoeuvre and maritime power projection; sets out the three main roles of UK maritime power – warfighting, maritime security and defence engagement; and explains the maritime contribution to joint action and the full spectrum approach.

This publication has been written primarily for joint staffs, officials, allies and partners in industry to provide a concise explanation of how maritime forces perform a vital role in protecting our nation and supporting its continued prosperity.
