1. 5m

Question 17

What are the six phases of operation for the Javelin?

Answer 17

• CLU Prep, Cooldown and Standby
• Activate AUR
• Track target
• Launch
• Flight Control
• Warhead Detonation

Question 18

What are the CLU Modes

Answer 18

Day

Night

Test

Off

Question 19

What does the Gunner do to ensure communication between CLU and Missile

Answer 19

The gunner squeezes and holds the CLU Fire Trigger switch to initiate the launch of the missile.

The Fire Trigger must be held for a minimum of 400 ms. The CLU Seeker Trigger is also being held.

Squeezing the CLU Fire Trigger removes a squib driver interlock and initiates the action of the missile RESTRAINT PIN SQUIB andthe CLU FIRE COMMAND.

Answer 31

2.3kg of PBXN-109 218g Zirconium Sponge Incendiary Pellets

Question 32

What is the control section arm and firing sequence

Answer 32

The rocket motor SAD provides an out of line detonator/squib whose electrical contacts are grounded and shunted in the safe position. The CIA CCA provides the SAD with 28Vdc power which rotates the rocket motor squibs to be “inline”. If the SAD is returned to zero volts the SAD will rotate back to its original (safe) position. The SAD should not be energized for more than 1 minute or the SAD may be damaged. Once the voltage is removed from a damaged SAD it will return to a safe position under the action of the return mechanism. A fire pulse providing more than 3.8 amps to each squib will fire the dual rocket motor squibs and ignite the rocket motor.
