Elevation locks limit how high or low the launcher can tilt, creating a defined and safe firing envelope that keeps the weapon within its mechanical stops and aligned with the sighting data. For this system, the standard settings are +30 degrees of elevation and -8 degrees of depression. These values establish the maximum upward tilt and the deepest downward tilt the launcher can safely reach, matching the missile’s ballistic characteristics and ensuring consistent zeroing and aiming. Using these specific limits helps prevent over-travel that could damage components or alter the aiming reference, while still allowing enough tilt to engage targets within the intended envelope. Other stated values would push the launcher beyond its safe mechanical range or fail to align with the documented ballistic and sighting setup, so they are not used.
