I can understand how a torpedo hit on a rudder could be 1/2 % but not 6%? Looking at the diagrams of the Bismarck event it seems like a 10 meter section of hull was hit . If this is what was required to jam the rudder into the screw, then that's 10m out of a 250m hull length or 1/25th of the hulls length.
You have to realize that rudder damage often means merely temporary damage. Both games have methods to determine when and if the rudder can be repaired or "unstuck". I'd also mention that temporary jams are a lot more common than permanent issues.
Comand at Sea uses a slightly different as opposed to straight line damage. One torpedo has that .5% chance of a rudder jam, but 4 torpedoes striking in rapid sucession could easily increase the chances many fold, though flooding/fires are more common than rudder damage.
The purpose of Command at Sea is to reflect that vessels taking a lot of damage at one time are more likely to sustain critical damage than those taking the same amount of damage over time due to damage control being overwhelmed, which is a pretty realistic approach for floods and fires, less so for rudder strikes IMO.
And that strike that damaged Bismarck's rudder may have been 4-5 meters away, but maybe a torpedo striking within 10 meters may well still cause the rudder to "stick" for a while.
How would such games rate the unlikely shell hit on HMS Hood?
With Command at Sea, about 1%, unless the vessel is taking a pounding from many hits, which the Hood was not.
With Seas of War, you have a 20% chance pf a magazine hit, 10% for a turret top which gives a very similar result. Of these, it's about 60% likely it was a main magazine, 40% for a secondary magazine. This is based on a vertical hit, which is far more likely than a horizontal hit from that range. Now, as long as the ship has not sustained a fair amount of damage, the magazine may be flooded, though this may or may not be in time to prevent the magazine from exploding.
I'd also add that while a secondary magazine explosion is not as bad as a primary one, there will be resulting fires and other damage that may trigger the main magazine to blow at some point.
And these effects are not automatic, they are based on the size and bursting charge of the projectile, but a battleship shell is about 80-100% likely to cause these effects.
a 380mm/L52 gun FULLY PERFORATING HULL HIT would have a 25-33% chance of hitting a magazine (main OR secondary)
Interesting, Alecsandros. Seas of war has about a 30% probability of this occurring, which seems right in line with the numbers from above.
Are these games computerized?
NO, I actually like them better not being computerized, makes it easier to understand the nuts and bolts behind the system. The numbers I am quoting are from two different games - I think Alecsandros in his 25-33% numbers is using real life percentages.
