36. Submarine Tactics: Considerations: Acoustic Advantage Speed Advantage
= Tactical Advantage (yes or no)

37. Submarine Tactics: Localization Attack Detect, Track, Classify
Operate per sensors
Maneuver to keep on beam
Attack
General due to clearances
Preferred firing position
Alertment position

38. Typical Deployment Cycles
SSN – typical 6 month
