Which of the following is NOT a part of a standard artillery round?

The correct answer is the propellant chamber, as it is not a component found in a standard artillery round. In the context of an artillery shell, the primary parts include the ogive, fuze, and base cover.

The ogive is the pointed front of the shell that helps reduce aerodynamic drag. The fuze is a critical component that activates the shell’s explosive device upon impact or at a predetermined time, enabling it to detonate correctly during its intended function. The base cover is part of the shell that seals the rear, often designed to withstand pressure and provide a secure enclosure for the propellant.

In contrast, the propellant chamber generally refers to components within the artillery system rather than the shell itself. Standard artillery rounds typically do not have a designated "propellant chamber" as a distinct part; rather, the round relies on the propellant charge surrounding or integrated within it to produce the necessary thrust for launching. Thus, understanding the distinct elements of an artillery round clarifies why the propellant chamber is not one of them.
