Question 12

(014) 1. What is the main difference between the Wing 1 MAF and the Wing 3 and 5 MAF?

Answer 12

The MAFSB at Wing 1 contains all of the support equipment and environmental control system equipment, whereas this equipment is located in an underground structure at Wings 3 and 5.

Question 13

(014) 2. How is the diesel generator in the LCSB started?

Answer 13

The facility manager will have to manually start the generator.

Question 14

(014) 3. Where is the controlled access to the LCC elevator shaft located?

Answer 14

The security control center (SCC)

Question 15

(014) 4. What is the purpose of the LCC blast door?

Answer 15

To withstand nuclear blast overpressure, provide environmental seal, and shield the LCC from electromagnetic pulse produced by a nuclear blast.

Question 16

(014) 5. What is the purpose of the ACP LCC?

Answer 16

Reports directly to the wing command post (WCP) and serves as the backup should anything happen to the WCP.

Question 17

(015) 1. What keeps groundwater from accumulating within the launch tube and damaging the solid propellant motors?

Answer 17

A sump pump, in a pit at the bottom of the launch tube.

Question 18

(015) 2. How is vertical movement of the launcher closure door prevented?

Answer 18

Weight (110 tons) and mated beveled edges on the closure sides and launcher roof.

Question 19

(015) 3. Why is approximately half of the upper-level LER shock-isolated?

Answer 19

To prevent the launch-critical equipment from ground shock damage produced by a nuclear blast.

Question 20

(015) 4. Why are there two removable steel hatches in the roof of the LSB?

Answer 20

They permit removal and emplacement of the brine chiller unit and diesel generator.

Question 21

(014) 5. What area of the LF does the IZ security system monitor?

Answer 21

The launch tube below ground level and the entrances to the launcher.

Question 22

(014) 6. What is the purpose of the vibration-sensitive transducers in the IZ security system?

Answer 22

The transducers detect attempts to tunnel into the launcher by turning vibrations into electrical signals that the security drawer looks for.

Question 23

(014) 7. What is the purpose of the service area on an LF?

Answer 23

For maintenance and support vehicle maneuvering and parking.

Question 24

(015) 1. What type of core design is used with the first-stage motor on an LF?

Answer 24

Six-point-star; hollow-core design

Question 25

(015) 2. How is missiles attitude controlled during first stage flight?

Answer 25

The nozzles, which move in response to commands issued by the guidance system to the NCUs, control the missile during first-stage of flight.

Question 26

(015) 3. How are aft closure and motor case protect from the effectss of propellant gases?

Answer 26

Molded plastic, Buna-N-Rubber, mastic insulation (resinous protective coating), and high-density graphite parts insulate the motor case, aft closure areas, and the nozzles from the effects of propellant gases.

Question 27

(015) 4. How is the propellant cast in the second-stage motor?

Answer 27

A combination six-point-star and round, hollow-core configuration with a star at the forward end.

Question 28

(015) 5. How is third stage separation achieved prior to burnout?

Answer 28

Signals from the missile guidance set (MGS) command shaped charges to blow the ports open at thrust termination to vent motor chamber pressure and create a momentary negative thrust.

Question 29

(015) 6. How does the RS reach its destination for RV jettison?
