What is primarily used to fire projectiles in naval operations?

The main method for firing projectiles in naval operations is through gun mounts. Gun mounts are designed to support naval artillery, allowing for the elevation and rotation necessary to engage targets accurately. They facilitate the loading, aiming, and firing of various types of naval guns, which are integral to a ship's weaponry for both naval and ground engagements.

While vertical launch systems (VLS) are used extensively for firing missiles, they are not primarily associated with traditional projectile firing as they typically handle guided munitions rather than unguided projectiles or shells. Over-the-side torpedo tubes are specifically meant for launching torpedoes and do not cover the broader category of projectiles fired from naval guns. The term "roller path plane" is not a standard component related to the firing of projectiles; rather, it relates to other mechanical systems within naval operations, often dealing with support structures.

In summary, gun mounts are the primary mechanism for firing projectiles on naval vessels, making them essential for offensive capabilities at sea.
