7.1.7.14 Ready and Time of Flight

When the ship is prepared to fire the first salvo, it reports READY followed by the time of flight in

seconds. The FO reads back the entire pre-firing report and commands FIRE. If the method of control

included AT MY COMMAND, the ship also reports READY before firing each round. The ship informs

the FO when there is a time of flight change of more than 5 seconds. An example of a pre-firing

report follows.

7.1.7.15 Special Instructions

Various special instructions the FO may use in attack of the target are discussed below.

1. FFE Interval

This is used to cause FFE rounds to be fired with a specific time interval between each salvo. The FO

announces number of salvos followed by a desired time interval (seconds understood); for

example, 10 SALVOS INTERVAL 30 FOR EFFECT.

2. Sustained Fire

If there is a requirement for Fire For effect to be spread over a specific period of time, the FO may

specify SUSTAINED FIRE. The command includes the number of salvos and the period of time in

which they are required to be fired; for example, SUSTAINED FIRE 20 SALVOS 5 MINUTES FOR

EFFECT.

3. Time on Target

The FO may require the initial salvos in Fire For effect to impact on the target at a specified time.

4. Continuous Illumination

The FO may require constant light on a target. He may specify a period of time the illumination is to

be effective. The ship determines the interval to fire the subsequent illumination salvos based on the

burning time of the projectile. The FO has to determine the total duration and the firing rate for the

illumination.

5. Coordinated Illumination

Mission to be carried out by following the same procedures for a NATO coordinated illumination

mission.
