#2 Anti-Submarine & Surface Warfare Stack 31-60 Flashcards
Search plan 1S ‘OAKTREE’ has what applications?
Area; intercept; lost contact; or bottom search conducted by two or more ships and may also use helicopters.
What is involved in the ASW search plan 3S ‘PINEAPPLE’?
Ships and aircraft are placed in search sectors around datum.
When will the final approach to datum start?
At ETA to TDA, or 1 tactical sonar range (TSR) from the FOC.
What is a DELIBERATE ATTACK?
An attack that is delivered with maximum accuracy with the objective of destroying the submarine.
What is an URGENT ATTACK?
An attack that disrupts the submarines firing plan and is conducted when danger from submarine attack is imminent.
What is allowed by PLAN RED 3A GEOGRAPHIC SECTOR?
Coordinated, two-ship ASW containment and attack.
What equipment supports the SQS-53 sonar by predicting tactical sonar ranges automatically?
Sonar In-Situation Mode Assessment (AN/UYQ-25 SIMAS).
What zigzag plans were developed for use within the TDA?
Ray and Yankee (ATP 3).
What AEGIS display system component can be tailored to show all ASW information normally displayed on a NTDS console or NC-2 plot?
Large Screen Displays (LSDs).
Which net is used for information exchanges between ships and fixed wing ASW aircraft engaged in coordinated ASW?
ASW Air Coordination Net.
Aboard ASW ships, which sound-powered phone circuit is used solely as a command circuit?
JS.
Which net may be used by the first SAU in place of ASCONNET ALPHA?
Screen Tactical Alpha (Remaining screen units shift to Screen Tactical Bravo as directed by the OTC).
What are the classes of surface unit ASW capability?
Long-range weapons and sensors; long-medium range sensors with weapons systems that require them to close within the TDA to engage the submarine; and short range weapons/sensors.
What are the graphic representations of the command’s estimate of the maximum submarine displacement from datum at a given time?
Furthest-On-Circles (FOC).
Why are limiting lines of approach applicable to nuclear submarine threats?
Because increased threat speed degrades threats sonar performance and increases likelihood of passive broadband detection.
