I'd like to see a true fire control system.

What we have in SH is a mismash of Position Keeper and Angle Solver. The actual fire control systems were comprised of 3 parts. The ownship's section, the Position Keeper and an Angle Solver. The PK consisted of Bearing, Range, Course and Speed dials or counters. The data could be inputted manually via small hand cranks, or in the case of say bearing could be selected to be inputted automatically from the Periscope or Sonar or Radar. Once the values had been inputted, the PK along with the ownship's section would generate the solution and keep it updated as the geometry between ownship and the target changed. Then that data again with the ownship's section would generate the weapon orders ie gyro angle and would show the gyro and and the torpedo track angle.

Often when in the middle of a convoy you don't have time to generate a solution especially when using manual targeting. With a real FCS we could input a solution based on seaman's eye, ie. a quick range measurement, a called angle on the bow and a swag on speed, input a final bearing and shoot. Additionally it would allow a couple of bearings and range calls to be plotted, the derived solution inputted and shoot with the scope down using the generated bearing of the PK.
