What rank structure should a new navy copy?

If a navy were created from scratch, which officer and NCO rank systems would make the most sense to copy?

The English officer titles are comparatively clear, but a new navy would probably need a more extensive NCO system than the modern Royal Navy uses.

The English pattern clearly distinguishes captain, commander, and other grades, though that preference is qualified by cultural bias and the awkwardness of lieutenant commander. The present lower-deck hierarchy would need expansion before being copied. Its compression reflects a smaller Royal Navy and its current operating model rather than a universal force-design solution. A larger or differently organized fleet might need more NCO grades to show which technical and leadership responsibilities its lower deck retains.
