User:Jareel_Skaj/Navy Shells
This page is showing the list of the key calibres in inches into a common units and related penetration of some of the naval shells in roughly the same calibre. This table is meant to give you a rough idea of how much protection does the ship armor give at a typical combat ranges. Going by inches as a base puts some nations in a disadvantage in terms of a number of entries in the table (notably Germans).
AP
Note: A number of guns (notably Japanese) use SAP instead of AP ammunition for the same purpose, but they are not listed here. 30° @ 5000m was selected to illustrate real ranges and hit angles. While not universal (e.g. ≥12" guns rarely shoot at targets so close) it should give you a rough idea about the performance for the shells boiled down to a single number.

HE
This list a pure HE shells, regardless of any HE-VT/HE-TF. This should give you an idea about the size of the explosive fillers in each of the calibres for when you're writing an articles about the guns or ships. Please, remember that the rate of fire and a number of guns makes a huge difference (use {{User:Jareel_Skaj/DPSGraph}} if you need to compare the pure HE DPS output).

Battleship gun ranking system created by the British naval historian Alexander Clarke. It's meant to rank the real-world capabilities of various naval guns used as a primary batteries of battleships. It takes the following characteristics into account: rate of fire, weight of shell, range of the gun (as of WW2), Armor-Piercing capability (@20 000 yards), weight of the bursting charge, any special pros/cons.
Pre-1930
Post-1930
Do not compare the score between pre-1930 and post-1930 guns. They are on a different scale. Each category (e.g. weight of the shell) is scored in relation to the rest of the group. Also pre-1930 scores use absolute range (which is largely a function of a turret) while post-1930 scores use a new, revised system where range is taken at the 20° gun elevation (reflecting more of a capability of the gun itself). |
