, Question 1
The ship suffers a complete loss of 60 Hz primary bus power in the forward
main machinery space. Which casualty control action must be taken FIRST to
preserve the integrity of the ship's C4I suite?
A. Shift the Joint Operations Center (JOC) to the emergency diesel
generator (EDG) bus and shed non-essential loads.
B. Secure all non-vital electronics to prevent a cascading overcurrent trip
on the remaining bus.
C. Start the emergency generator and immediately cross-connect the
forward and aft buses.
D. Manually trip the main circuit breakers to isolate the faulted bus
before restoring power.
Correct Answer: A - Shift the Joint Operations Center (JOC) to
the emergency diesel generator (EDG) bus and shed non-essential
loads.
RATIONALE
The JOC is the ship's most critical C4I space and must be transferred
to the EDG bus with non-essential loads shed to prevent overloading
the generator. Immediate cross-connection (C) risks paralleling a
faulted bus, while manually tripping breakers (D) without first
securing the fault may worsen the casualty. Securing all electronics
(B) would unnecessarily degrade command capability before the EDG
is online.
Question 2
During a strait transit, the Seventh Fleet commander requires continuous,
low-probability-of-intercept (LPI) reachback to a national command authority.
Which Blue Ridge capability best satisfies this requirement?
A. The AN/USC-38 Extremely High Frequency (EHF) satellite
communications terminal
B. The AN/WSC-6 SHF satellite communications terminal
Page 2
, C. The AN/SRC-59 UHF line-of-sight radio suite
D. The AN/SSQ-82 multichannel UHF satellite communications system
Correct Answer: A - The AN/USC-38 Extremely High Frequency
(EHF) satellite communications terminal
RATIONALE
EHF (AN/USC-38) provides survivable, LPI/LPD, jam-resistant
communications suitable for national-level reachback during
high-threat transits. SHF (B) offers high bandwidth but lacks the
inherent LPI/LPD and anti-jam characteristics of EHF. UHF
line-of-sight (C) and multichannel UHF SATCOM (D) are more
vulnerable to interception and jamming.
Question 3
A fire is reported in the Joint Intelligence Center (JIC) while the ship is at
General Quarters. Which damage control principle should guide the initial
boundary-setting decision?
A. Establish boundaries one compartment beyond the fire to balance
firefighting access with containment.
B. Establish boundaries at the nearest watertight bulkheads and set a
reflash watch.
C. Flood the space immediately to prevent vertical spread through
cableways.
D. Secure all ventilation to the space and establish boundaries at the next
deck above and below.
Correct Answer: D - Secure all ventilation to the space and
establish boundaries at the next deck above and below.
Page 3
, RATIONALE
In a vital C4I space with extensive cableway penetrations, the priority
is to stop vertical and horizontal spread by securing ventilation and
setting boundaries at the next deck above and below. Boundaries one
compartment away (A) may be insufficient given cableway spread.
Immediate flooding (C) is a last resort and would destroy critical
intelligence systems. Nearest watertight bulkheads (B) may not
account for overhead/underfoot spread.
Question 4
Which statement most accurately describes the relationship between the ship's
Tactical Action Officer (TAO) and the embarked Seventh Fleet staff during
amphibious operations?
A. The TAO exercises tactical control of all embarked staff assets during
general quarters.
B. The TAO is responsible for the safe navigation and maneuvering of the
ship, while the staff controls embarked forces.
C. The TAO integrates shipboard tactical defense with the staff's
operational planning but does not command embarked forces.
D. The TAO reports directly to the fleet commander for all tactical
decisions, bypassing the commanding officer.
Correct Answer: C - The TAO integrates shipboard tactical
defense with the staff's operational planning but does not
command embarked forces.
RATIONALE
The TAO is the commanding officer's representative for tactical
employment of the ship and integrates shipboard defense with the
embarked staff's operational plan, but does not command embarked
forces. Option A overstates the TAO's authority over staff assets.
Option B confuses the TAO with the Officer of the Deck. Option D
violates the chain of command; the TAO always answers to the CO.
