Steam Engines and endurance?

Do steam engines typically have more range and endurance than an internal combustion engine giving out the same power? Like for a ship, for example?

    Yes, large steam engines are more efficient than internal combustions engines. Largest application is in power plants.

    Coal power plants are exclusively steam. Oil and natural gas also fire steam plants. Steam plants take a long time to start up and get running, thus, best suited for base power plants, not peaking plants. They are also large and heavy, thus, used some in ships where fuel efficiency helps operating costs. Convenience of oil fired diesel engines has replaced steam in many mobile applications, as diesel efficiency is not too much worse than steam.

    Also, military does not like steam, as boilers contain lots of very hot steam. One hole from a bullet, and you have a big mess.

    They are not as efficient as an internal combustion engine which is why you now see very few steam engines in anything.

    As for range and endurance, keep supplying the steam engine with fuel and water (they use a lot) and they perform exactly as well as an internal combustion engine with the same criteria.
