B) Close-In Weapon System (CIWS)
C) Evolved SeaSparrow Missile (ESSM)
D) Standard Missile 6 (SM-6)
B) Close-In Weapon System (CIWS)
Rationale: CIWS operates as a terminal defense radar-guided rapid-fire gun
designed to destroy incoming missile threats that penetrate outer defense layers.
9. What is the alphanumeric CWC call sign designation assigned to the Air and Missile
Defense Commander (AMDC)?
A) W / C
B) Z / B
C) Q / E
D) P / K
A) W / C
Rationale: In standard Navy CWC architecture, Alpha Whiskey (W) and Alpha
Charlie (C) serve as the primary and alternate call signs for the AMDC.
,10. What type of missile is primarily used by US Navy cruisers and destroyers for long-
range, deep overland precision strike missions?
A) Harpoon Missile
B) Standard Missile 2 (SM-2)
C) Tomahawk Land Attack Missile (TLAM)
D) Sea Sparrow
C) Tomahawk Land Attack Missile (TLAM)
Rationale: TLAMs are long-range, all-weather, subsonic cruise missiles deployed
from surface ships and submarines for land-attack missions.
11. Which primary sensor system is operated by the Electronic Warfare (EW) Operator
inside the CIC to detect, evaluate, and counter radar emissions?
A) AN/SQS-53
B) AN/SPY-1
C) AN/SLQ-32
D) AN/SPS-49
C) AN/SLQ-32
Rationale: The AN/SLQ-32 electronic warfare suite provides electronic support
measures (ESM) and electronic countermeasure (ECM) capabilities managed by the
EW operator.
12. Which warfare commander acts as the primary coordinator for offensive cruise
missile and heavy bomber strikes against land targets?
A) IOWC
B) AMDC
C) STWC
D) SCC
C) STWC
Rationale: The Strike Warfare Commander (STWC) controls aircraft and cruise
missile strikes targeting inland structures or hostile military bases.
13. What CWC call sign designates the Sea Combat Commander?
A) W / C
B) Z / B
C) Q / E
D) X / Y
B) Z / B
Rationale: Alpha Zulu (Z) and Alpha Bravo (B) are the assigned call signs for the
Sea Combat Commander (SCC).
14. What occurs during a "Semi-Active" homing guidance phase of a missile flight?
A) The missile uses an internal optical camera to steer itself.
B) The missile relies on an external radar from the firing platform to illuminate the
target.
C) The target transmits radio waves directly into the missile receiver.
D) The missile tracks the thermal infrared signatures of the ocean water.
B) The missile relies on an external radar from the firing platform to illuminate
the target.
Rationale: Semi-active homing requires the ship's or aircraft's fire control radar to
continuously bounce energy off the target for the missile's nose receiver to follow.
15. Which watchstation acts as the technical liaison between systems control engineers
and the tactical warfare commanders in the CIC?
A) AIC
B) EW Operator
, C) CSC
D) TIC
C) CSC
Rationale: The Combat Systems Coordinator (CSC) bridges the gap between
hardware technicians and operational watchstanders, monitoring technical faults in

B) Centralized planning
C) Command by negation
D) Local coordination
A) Decentralized execution
Rationale: Decentralized execution delegates authority to subordinates on the scene
