What adjustment is necessary when switching between different types of ammunition?

When switching between different types of ammunition, it is essential to perform the calculation of ballistic data. Each type of ammunition has unique characteristics, including weight, ballistic coefficient, and drag, which significantly affect its trajectory, range, and overall performance.

The ballistic data must be recalibrated to account for these differences to ensure accurate targeting and effective engagement of the target. This adjustment involves assessing the new ammunition's ballistic tables, which provide information on the trajectory, drop, windage, and other crucial factors affecting its flight path. By recalculating this data, the crew can make informed adjustments for elevation and deflection, ensuring that rounds land precisely where intended.

While alignment of the gun barrel, calibration of the firing system, and modification of the recoil system may be necessary in other maintenance or operational contexts, they do not directly address the inherent variations in performance associated with using different types of ammunition. Therefore, the calculation of ballistic data stands out as the critical adjustment necessary for effective artillery operations when changing ammunition types.
