Curtiss S

Curtiss S refers primarily to a specific variant of aircraft engine manufactured by the Curtiss Aeroplane and Motor Company. This engine, typically a large displacement V-12, was developed and produced during the early to mid 20th century, particularly during the interwar period and World War II.

The Curtiss S series engines were known for their high power output relative to their weight and were employed in a range of military and commercial aircraft. Different variants within the S series offered varying horsepower ratings and were adapted for different aircraft types and operational requirements. The precise specifications and performance characteristics would vary depending on the specific model number within the "S" designation.

While "Curtiss S" commonly designates the engine series, it can also, less frequently, refer to other products or initiatives associated with the Curtiss Aeroplane and Motor Company that were identified with the letter "S," although such usages are considerably rarer and would usually involve a more specific identifying designation.
