RADIO ROOM/ESM STATION
In Sub Command the Radio Room and ESM (Electronic Support Measures) stations are combined.
The radio is used to receive intelligence and tasking updates while ESM allows you to detect and
classify contacts when at periscope depth.
RADIO MESSAGES
The radio is your link with the outside world.At the beginning of each mission, you should always
review your current mission orders and check for any new intel or tasking messages. Incoming
messages can provide crucial updates on targets.This information can include extremely helpful
information on a target’s last known position and even its estimated course and speed.
To receive messages you must raise the radio mast or stream the floating wire antenna.There are
advantages and disadvantages to both modes.The floating wire receives messages far more
slowly than the radio mast, but the wire can be used under ice and you don’t have to be at
periscope depth to use it.
While the mast collects signals quickly, you must be at periscope depth to use it. Because it
protrudes from the water, the radio mast creates a wake that can be seen by aircraft and provides
a surface that can be detected by enemy radar.
There are speed restrictions when using either the wire or the radio mast.
■
Radio Mast:
You must be at periscope depth and at 8 kts or less when the sail is submerged to
avoid damaging the mast.
■
Floating Wire:
You must not exceed 18 kts or damage occurs. Make sure the wire is streamed
to at least half of its length in order to ensure message reception.
RECEIVING RADIO MESSAGES

1.
Select either the floating wire antenna or the radio antenna mast to receive the message.
