Submarine Tactics:
Considerations:–Acoustic Advantage–Speed Advantage
= Tactical Advantage (yes or no)
Submarine Tactics:
Localization– Detect, Track, Classify – Operate per sensors– Maneuver to keep on beam
Attack– General due to clearances– Preferred firing position– Alertment position
Typical Deployment Cycles SSN – typical 6 month
SSBN / SSGN - ~ 112 day cycle
