Hi, I'm asking for help. What "Artillery Fire Control System" was on the Sims class destroyers? I'm a bit confused on the information..... I can't find a reliable answer on my services.

" 1) T1 director (Wilson).

2) The T4 gun director is used with the M1918 3-inch pistol

3)The T6 was built by the Sperry Corporation in 1930 and standardized as the M2 director.

4) The M3 was standardized over the T8 in 1934

5) M4 was standardized in 1939

6) The M5 Gun Director mechanical pistol, an
American-made Kerrison predecessor, for use with
the M1 37mm and M1 40mm guns

7) M5A1

8) M5A2

9) The M7 director pistol was standardized in 1941 and
is similar to the M4, but a power regulator was
added to the gun. It is still described as a mechanical
system. for use with 90mm cannon

10) M7A1B1

11) M7A1B2

12) T10 is standardized as M9 gun for use with 90mm
cannon made by Bell Labs

13) M9B1

14) M10 gun director electrical for use with the M1

" In a typical World War II ship the fire control system connected the individual gun turrets to the director tower (where the sighting instruments were located) and the analogue computer in the heart of the ship. In the director tower, operators trained their telescopes on the target; one telescope measured elevation and the other bearing. Rangefinder telescopes on a separate mounting measured the distance to the target. These measurements were converted by the Fire Control Table into the bearings and elevations for the guns to fire upon. In the turrets, the gunlayers adjusted the elevation of their guns to match an indicator for the elevation transmitted from the Fire Control table — a turret layer did the same for bearing. When the guns were on target they were centrally fired.

Even with as much mechanization of the process, it still required a large human element; the Transmitting Station (the room that housed the Dreyer table) for HMS Hood's main guns housed 27 crew."
