BDOC Maritime Warfare questions with verified
answers
Active Terminal Homing Ans✔✔ -Weapon contains a radar that performs search
and acquisition. An internal computer calculates a course to intercept the target
Semi-Active Terminal Homing Ans✔✔ -Target is illuminated by a fire control
radar or electro-optical sensor from the launching platform; weapon "needs a
little help"
Passive Terminal Homing Ans✔✔ -Weapon tracks the enemy source
-Noise Radiation Homing
-Anti-Radiation Homing (ARM)
-Infrared
Command Guidance Ans✔✔ -Guidance commands come from sources outside
the weapon in order to get it to an intercept
Self Contained Guidance Ans✔✔ -GPS
Inertial Navigation System (INS)
Terrain Contour Matching (TERCOM)
Digital Scene Matching Area Correlator (DSMAC)
GPS Ans✔✔ -Satellite based navigation system that uses satellites to send digital
signal to weapon receiver that determines its position relative to the target
position. Examples include SM-2, SM-3, SM-T, SM-6, and TLAM
,Inertial Navigation System (INS) Ans✔✔ -Uses accelerometers to make
corrections in flight to keep weapon on proper trajectory. Examples include
TLAM, SLAM-ER, JSOW, and JDAM
Terrain Contour Matching (TERCOM) Ans✔✔ -uses an altimeter and a database
of stored 3D navigation "maps" that guide the missile en route to its target.
Example includes TLAM
Digital Scene Matching Area Correlator (DSMAC) Ans✔✔ -uses a digital camera
and image correlator to find the target. Example includes TLAM

Primary Function: combines PASSIVE directional and calibrated wide band omni-
capability
3 Principles of CWC Ans✔✔ -Collaborative Planning
Decentralized Execution
Command by Negation
CWC Ans✔✔ -Composite Warfare Concept
Supported Commander Ans✔✔ -Receiving assistance from another commander
Supporting Commander Ans✔✔ -Provides assistance to another commander
, Operations Order (OPORD) Ans✔✔ -Directive issued by the operational
commander to subordinate commanders affecting the coordinated execution of
an operation
Operational Tasking (OPTASK) Ans✔✔ -Guidelines for operational conduct
Daily Intentions Message (DIM) Ans✔✔ -Messages with an immediate impact on
operations to convey direction from the latest iteration of the commander's
decision cycle
- Information that comes out daily
CWC Diagram Ans✔✔ -
Two Types of Radio/Telephone Nets Ans✔✔ -Directed/Controlled - need
permission to transmit from Net Control Station
Free/Uncontrolled - no permission needed from Net Control Station to transmit
Radiotelephone Nets Ans✔✔ -Unsecure Net
- No protection, nothing encrypted
- Everyone can hear
- Use call sense
- Sensitive information must be encoded manually
Secure Net
- Protected by cipher
- Everyone hears static
