One question that was asked was why is Face hard penetration more than homogeneous penetration. Shouldn't it be harder to penetrate face hard armor? I suppose it should be but a capped shell will penetrate more facehard armor but the cap slightly absorbs some energy in homogeneous armor. At least that is what calculated armor penetration puts it. Here is a link to a comparison of armor penetration for 76mm and 90mm tank guns.

So the Naval Armor and Ballistics program update is complete. Link to NAAB2.0 download.

More work is being done on Naab 2.0 and further testing. Here is a look at the documentation for the project. Link

The update of NAaB 2.0 is winding down. The project has taken longer than I hoped. Now, working on stuff outside the last version. Making up HE penetration. There is a formula for that but I found it doesn't jive with my data. I am trying to match it up with TM 9 1907 firing tables of concrete penetration. If concrete is 1/15 the armor of armor. Now there is some debate of the concrete to armor multiple so 1:15 is my compromise. One online table has it at 1:10. The FaceHard program itself rates cement as 1:25 of armor, while TM 9 1907 armor to concrete ratio of AP gun penetration is 1:6. The other problem hcwclcr unlike Facehard rates all shells as perfect indestructible bodies. But there are Common, and SAP shells which are weaker than AP, So, I may have to add some factor to weaken these.

Been working on this project for over a month now. I hate programming. It is too consuming of my time. I work on it to the detriment of any life outside programming. Well the hcwclcr was fixed and NAaB is almost done. It needs some more testing and cleaning up,

The HCWCLCR armor penetration program into windows is on hold. After converting it to TP I used the code to create a Delphi windows program, Unfortunately there seems to be a bug HCWCLCR so I have to await an update on that before I can complete it.

I'm trying to complete another project which is translating Nathan Okun's HCWCLCR armor penetration program into Turbo Pascal. It eventually will be converted to Delphi windows program to be incorporated in NaaB. The Naval Armor and Ballistics program. Right now it is going slowly as old BASIC isn't the easiest to make into a structured program.

The sighting error system is being updated. The 'Research' link shows the menu of the ballistic engine listing some of the standard deviations of the range error of German sights. The values are partially based on British Error Estimation memo AORG #514 excerpt to the right. Per conversion the standard deviation is 1.25331 times the mean deviation.
If one is interested it can be seen the 'even chance' is the 50% zone and this is 1/2.438 x the 90% zone. This is important in converting British 90% accuracy deviation to 50% zone deviation.
