Okay . . . I give up . . . in what year did the Mk-38 GFCS enter service. I'm working on a 1934 Refit and I don't need any more mistakes.
funny that google and wikipedia (should give an basic idea):
http://en.wikipedia.org/wiki/Ship_gun_f ... rol_System
The Mk38 Gun Fire Control System (GFCS) controlled the large main battery guns of Iowa-class battleships. The radar systems used by the Mk 38 GFCS were far more advanced than the primitive radar sets used by the Japanese in World War II. The major components were the director, plotting room, and interconnecting data transmission equipment. The two systems, forward and aft, were complete and independent. Their plotting rooms were isolated to protect against battle damage propagating from one to the other.
