SUMMARY
Over the past 30 years electric propulsion has been frequently selected as the propulsion system of choice for
various types of warship and auxiliary ship in several different nations’ navies. Throughout this period, the
authors have been involved with Royal Navy electrical power and propulsion systems as operators, maintainers,
trainers, designers, procurers and testers
This paper will present the authors view of the advances achieved over this period, identify the drivers causing
the changes and make suggestions about how future systems may develop
INTRODUCTION
During the 1980’s the UK Royal Navy’s Type 23 Frigate and the Upholder Class submarines were being developed
and built and both were in service by 1990. Whilst electrical propulsion had been previously used for surface
warships and submarines, these were early applications of modern power electronics to electric propulsion of Royal
Navy warships, albeit at relatively low shaft powers
Since then Royal Fleet Auxiliary’s Auxiliary Oiler (AO) and Royal Navy’s Landing Platform Dock (LPD) have
entered service with higher power electric propulsion systems and the Type 45 Destroyer is undertaking trials with
yet higher shaft powers. This sequence that introduces modern electric propulsion to the Royal Navy is understood
to have achieved both military advantage and reduced running costs.
Looking to the future, there are opportunities for electric propulsion to be adopted by future surface combatants and
submarines but the challenge is to provide suitable power dense and fully integrated electrical power and propulsion
technologies
During the 1990’s the authors foresaw this need and in a series of papers [1], [2], [3], [4], [5] & [6] identified the
technologies that they anticipated would achieve the power density objectives. In the event, the majority of the
novel developments anticipated did not come to fruition but the current power density challenges have been
achieved by incremental development of existing technologies, innovative approaches to the system as a whole and
a focus on heat management.
Extrapolating from this the authors anticipate future power density challenges being achieved in a similar manner,
at least until inevitable technology breakthroughs are achieved in non-naval arenas - such as High Temperature
Superconductivity (HTS) and Silicon-Carbide Semiconductors
