What is the NATO code assigned to JP-4 fuel?

The NATO code assigned to JP-4 fuel is F-40. JP-4, also known as Jet Propellant-4, is a type of aviation fuel that is a mixture of kerosene and gasoline. It is known for its lower freezing point and capability to withstand higher temperatures, making it suitable for various military aviation applications.

The NATO codification system provides a standardized method for identifying fuels and other supplies to ensure compatibility and efficiency among NATO forces. In the case of JP-4, the designation F-40 reflects its specific properties and intended use within military operations.

In contrast, other options such as F-36, F-44, and F-50 correspond to different fuel types or blends that have distinct characteristics and applications. F-36, for instance, represents another fuel variant, while F-44 and F-50 refer to other types of aviation fuels, each with their unique compositions and performance characteristics.
