Self-Propelled Howitzer Components: Chassis: The mobile platform that houses the gun and crew, providing mobility and protection. Gun: The large-caliber artillery piece for firing shells at various targets. Fire Control System: Includes electronics and targeting systems to ensure precision. Suspension and Track System: Provides movement over rough terrain. Powertrain: Includes the engine and transmission for mobility. Naval Gun Components: Gun Barrel: The large-caliber barrel for firing shells. Mounting and Elevation Mechanism: Allows for aiming and adjusting the gun's elevation and rotation. Fire Control System: Coordinates the targeting, firing, and tracking functions. Loading Mechanism: Automatic or manual systems to load ammunition into the gun. Power Supply: Provides electrical power to the gun and associated systems. In essence, these components work together to ensure the effective use of artillery on land (in self-propelled howitzers) and at sea (in naval guns).
