|
Easiest formation
Formed in a line of bearing ahead or astern of the guide. Used to transit restricted waters. |

Used for searches |
|
|
Line of Bearing
|
Formed in either a relative or true bearing from the guide other than ahead, astern, or abeam.
|
|
|
Diamond
|
Provides additional maneuvering room without increasing length of the formation
Increases mutual anti-aircraft fire |
|

Who orders the formation?
|
As directed by Officer in Tactical Control (OTC)
Executed on FORM signal |
|
|

|
form on guide in order of sequence number
|
|
|

|
form on guide nearest ship first
|
|
|
When forming or changing a formation:
The guide comes to... And all other ships... |
the guide comes to base course and speed
all other ships fall in on the guide. |
|
|
Who is the guide?
|
usually designated by the senior officer in tactical control (OTC).
remains the guide until another is designated or until a maneuver results in an automatic shift of the guide. |
|
|
Does the guide ship have to be the ship on which the OTC is embarked?
|
No!
|
|
|
Maneuvering
|
A change of course, speed, formation, or any combination of these, made by a ship to adjust position or to take a new position.
|
|
|
3 different movements, maneuvering
|
Turn (change of course and formation)
Corpen (change of course) Formation (change of formation) |
|
|
Turn
|
Each ship turns simultaneously on signal.
Ships stay on the original true bearing from the guide. Can be done from any formation. Drill Analogy (flanking movement) TRUE bearing to the guide remains the same |
|
|
Corpen (Wheeling)
|
Each ship changes course but the formation remains the same.
Ships stay on the original relative bearing from the guide. Can be done only from column, line abreast or diamond. Drill Analogy (column movement) |
|
|
Corpen (Wheeling), In relation to the guide
|
RELATIVE bearing to the guide remains the same.
|
|
|
Corpen (Search Turn)
|
Used to maintain search area integrity
Can be done only from line abreast or loose line abreast Ships must be at 1,000 or 1,500 yards separation Guide automatic shifts to the outboard ship Ships “swap” sides in relationship to the guide. Course Change Limitations: Minimum – 45º Maximum – 135º |
|
|
Maneuvering rules
|
Avoid other ships that have right of way:
ships engaged in minesweeping flight operations, or underway replenishment ships in the main body ships in the screen Junior ships stay clear of senior ships Usually better to pass astern |
|
|
3-2-1 Rule
|
When operating with Carriers: pass no closer than 3 nm on the bow, 2 nm abeam, or 1 nm astern of the Carrier.
When operating around other ships: in thousands of yards not nautical miles. |
