      abstract = {There have been many papers presented over the years  claiming to put a definitive, ideal propulsion system  forward for a particular vessel, with solutions varying  from Mechanical through Hybrid, to Integrated Full Electric  Propulsion. The ships associated with these differing  propulsion systems also vary hugely, from small offshore  patrol boats through larger platforms, such as Type 23,  Type 45 and potentially her successor in the destroyer  category, to the largest ships ever commissioned to the  Royal Navy, the Queen Elizabeth class aircraft carriers.  This paper seeks to explore the range of options available,  with some of the pros and cons of different solutions,  through a lens of differing ship types, and mission/role  profiles. The aim is not to conclude a definitive solution,  but provide the discriminators/differentiators to be  considered when making the selection. Aspects to be  considered as part of this analysis comprise a range of  differing drivers and constraints including: ship’s  lifespan, vessel size, operating environment, combat role,  likely operating profile, future-proofing requirement, such  as the growth and impact of non-propulsion loads, potential  crew/maintenance impacts, the desire for fleet commonality  and emerging requirements, such as emissions and  neutral/zero carbon aspirations as well as affordability  and cost of ownership. While none of these aspects alone  will provide a definitive discriminator to the selected  option, each of them influences the choice in a unique way.  Selecting the 'ideal'  propulsion becomes  an exercise in trading off each of the competing demands in  order to find a suitable solution.The replacement for Type  45 will be considered in more detail by the authors, whose  companiesbetween them have been the leading suppliers of  propulsion systems and shipbuilding for the post-Cold War  UK Navy.},
