What type of fuel is primarily used for propulsion on ships?

The primary fuel used for propulsion on naval ships is F-76, which is a type of naval distillate fuel. It is specifically formulated for marine applications and possesses the properties necessary for efficient operation of shipboard engines. F-76 is designed to provide optimal performance in terms of energy content, stability, and storage life, making it suitable for both diesel engines and gas turbine propulsion systems used in naval vessels.

F-44, while a type of fuel used primarily for aircraft (like jet fuel), is not appropriate for ship propulsion. Gasoline, typically used in smaller vehicles and not in large ships due to its volatility and lower energy content, is not suitable for marine propulsion systems. Diesel fuel is commonly used in various sectors, but specifically for naval applications, F-76 is the designated fuel to meet the requirements of ships' power systems, ensuring reliability and effectiveness in marine operations.
