Sub Fire control details?

[Adam106]

Hey,

I know there are some very knowledgeable skippers out there and possibly even a few retired ex-submariners that may be able to help with a curious question regarding fire control....

In DW with the US subs, we can assign 4 trackers to each of the sonar arrays. This means we can receive real time, up to date bearings etc for 4 individual targets. I suppose if you could theoretically track 4 each with both the sphere and towed arrays you get 8 real time inputs (and admittedly unlikely, but 12 with the hull array as well).

My questions is how does this compare with the real world capability - both 688 and Seawolf? From digging around a little online, I would imagine the 4 trackers capability sounds about right for at least an early 688. It appears the early 688's used the Mark 117 fire control system.

This source doesn't exactly reveal the number of targets that can be tracked simultaneously. However the info for the Mk113 system, which was used in the Sturgeon class indicates that 2 trackers were available, along with a greater number of tracks stored in memory (In game terms - stored on the Nav map display). Mk117 was an evolution of this earlier system, could a modest increase to 4 be expected? Where does this leave later systems such as BSY-1 and the presumably more advanced Seawolf / Virginia versions. I guess these days the system is able to handle trackers on dozens of contacts at once.

Might be a long shot but anyone got an insight into these details? Cheers.
