What type of special purpose buoy is used for air- subsurface communication?
ATAC (air-dropped two-way communications)
What is indicated by the CERTSUB (certain submarine) classification?
A contact that has been sighted and positively identified by competent personnel as submarine
What is indicated by the PROSUB (probable submarine) classification?
a contact displaying strong cumulative evidence of being a submarine
What assessment must always accompany a POSSUB classification?
Low or High confidence contact
What is indicated by the NONSUB (non submarine) classification
a contact has characteristics that exclude the possibility that it is a submarine
What type of search is used when a torpedo-firing submarine is in position to menace a mission-essential unit (MEU)?
an intercept search (application of a close search)
Search plan IS ‘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 aircrafts 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 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 submarine’s 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 an NTDS console or NC-2 plot
Larger-screen displays (DSDs)
Which net is used for information exchanges between ships and fixed wing ASW aircraft engaged in coordinated ASW?

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 (FOC0s
Why are limiting lines of approach applicable to nuclear submarine threats?
Because increased threat speed degrades threat sonar performance and increase likelihood of passive broadband detection
