Would it be the first ship of its kind in Surface Fleet with electric-diesel propulsion?
CODLAG CODELAG CODELOG CODOE slap any combination you want
It was in use before and some even used on some warships but recently getting more attention.
CODELOD can also be referred as CODOE since one does not expect a sustainable pure electric propulsion on a warship.
2 large diesel engines to run the vessel at maximum speed
2 medium diesel engines to run the vessel at the economic speed, this was particularly chosen because CODOD/CODAG was not possible (required heavy modification and space constraints).
However i think it is still whether it will be "OR" or "AND"
PS. If you are referring to the TN, then TCG Anadolu may be first after the MCMWs.
