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.

inch	mm official	mm SI calculated	Penetration @ 30° @ 5000m	TNT equivalent (kg)
3	76	76.2	30mm 37mm	0.06kg 0.13kg
4	102	101.6	–	–
5	127	127	93mm 86mm	0.77kg 1.30kg
6	152	152.4	100mm 177mm	0.80kg 1.88kg
8	203	203.2	214mm 247mm	1.62kg 3.16kg
12	305	304.8	275mm 419mm	5.66kg 18.79kg
14	356	355.6	415mm 420mm	11.11kg 12.21kg
15	381	381	390mm 416mm	20.68kg 25kg

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).
