Question 10

Primary System

Answer 10

includes all circuits necessary
for controlling armament, engineering, damage control,
maneuvering, and surveillance functions during battle. These circuits are designated JA through JZ

Question 11

Auxiliary System

Answer 11

duplicates many of the
primary circuits for the purpose of maintaining vital
communications in the event of damage to the primary
system. Auxiliary circuits are separated as much as
possible from primary circuits. Circuit designations are
the same as the primary system, preceded by the letter X (XJA, X1JV, and so on).

Question 12

Supplementary System

Answer 12

X1J through X61J,
consists of several short, direct circuits, such as fromthe
bridge to the quarterdeck or from the quarterdeck to the
wardroom. Because circuits in the supplementary system usually
are not manned, most circuits contain a buzzer system
so that one station can alert another station that
communications between the two are desired.
