000010628 520__ $$aFuture warship design will need to negotiate several emerging hurdles with regards to performance, complexity, capability, and resilience while balancing cost of ownership and environmental sustainability. Over the past two decades, most new warship programmes have fielded multi-role capability, but with rapid advancements in mission systems technology the platform systems selected need to be more adaptable now than ever to enable through life technology insertion throughout a service life of up to 50 years. To facilitate this, capital warships have and will continue to become increasingly electric, with deeper integration of ship and mission systems.
While the electrification of modern-era warships has been commonplace since the early 1990s, in-service experiences on first generation Integrated Full Electric Propulsion (IFEP) or Integrated Power Systems (IPS) must be considered alongside user requirements for a new programme. The RN Type 45 destroyer, Queen Elizabeth Class (QEC) carrier and the USN DDG-1000 destroyer programmes have yielded some interesting learning opportunities in several areas.
This paper will provide an insight into some of the learning points in the development of the power plants for these first-generation electric warships. It will then provide an insight into enabling approaches, techniques and technologies - and will specifically consider power management, prime mover type and size and associated impact on power system architecture, platform design and operability including resilience, efficiency and emissions. Some of these will provide opportunities for the discerning system designer and naval architect that were previously unavailable, and if leveraged, will ensure optimal designs giving enhanced performance and functionality in the second generation whilst simultaneously driving down platform costs and emissions.
