indicator blinks in the tube’s Launch Control Panel.The name of the weapon originally loaded in
the tube displays in the Tube Status Bar while the name of the weapon to be loaded appears in the
Tube and Weapon Selection Panel.
Once the original weapon is unloaded the name of the weapon being loaded displays in the Tube
Task Bar and the Target Assignment is cleared. (You must reassign a target to the new weapon
from the Target Display.) The presets for the new weapon appear in the Presets Panel.The reload
process is not complete until the Weapon Stowed indicator stops blinking.
Sub Command Tip: Be very careful where you click in the Tube and Weapon
Selection Panel. If you intend to select the tube number but click the weapon
name instead, you start a reload of that tube. A reload time consuming!
