By definition, the LF has to be capable yet affordable, a difficult balance to strike, but a dichotomy which has to be addressed particularly given the cost pressures our world’s navies are under. Whilst low engine loading at loiter speeds may lead to fuel inefficiency and increased maintenance burden, a purely mechanical Combined Diesel and Diesel (CODAD) propulsion system is attractive from a simplicity perspective. Hybrid propulsion architectures, using electrical machines as motors for low-speed operations, can be employed as a way to address this part of the operating profile. This paper explores to what degree a hybrid solution is appropriate for a LF through the consideration of a number of factors. 000007630 542__ $$fCC-BY-NC-ND-4.0 000007630 6531_ $$aWarship 000007630 6531_ $$aFrigate 000007630 6531_ $$aPropulsion 000007630 6531_ $$aCODAD 000007630 6531_ $$aHybrid 000007630 6531_ $$aPTI 000007630 6531_ $$aPTO 000007630 6531_ $$aSpatial Integration 000007630 6531_ $$aCost 000007630 7001_ $$aNewman, S M$$uBMT Defence & Security Ltd, Bath, UK 000007630 7001_ $$aSimmonds, O J$$uBMT Defence & Security Ltd, Bath, UK 000007630 773__ $$tConference Proceedings of INEC 000007630 773__ $$jINEC 2018 000007630 789__ $$whttps://zenodo.org/record/2530627$$2URL$$eIsIdenticalTo 000007630 85641 $$uhttps://imarest.org/inec$$yConference website 000007630 8564_ $$9a3df0b63-8795-4b96-b156-12a7c97a35e3$$s8245201$$uhttps://library.imarest.org/record/7630/files/INEC%202018%20Paper%20085%20Simmonds%20FINAL.pdf
