  17. 17. Ohio Class SSGN
  18. 18. SSN/SSGN Missions and SSBN • Intelligence, Surveillance and Reconnaissance (ISR) • Mine Warfare • ASW and ASuW • Power Projection and Strike Warfare • Landing Special Operations Forces • Sea Control • Strategic Deterrence
  19. 19. Intelligence Surveillance and Reconnaissance • Difficult to detect • Capable of transmitting real-time information • ACINT and collection of tactical information • Littoral reconnaissance prior to amphibious warfare
  20. 20. Support of Surface Units • Highly capable surface and subsurface interdiction platform • 20% of CSG Tomahawk firepower • Mine detection by UUV’s and acoustics
  21. 21. Strike Warfare Precision Strike on shore based targets up to 650 nm. Tomahawk (TLAM)
  22. 22. Special Operations SEAL transportation and recovery (EOD if attached) SDV ASDS SSGN
  23. 23. Strategic Warfare
  24. 24. Submarine Tactics: Considerations: Acoustic Advantage + Speed Advantage = Tactical Advantage
  25. 25. Submarine Tactics: Localization  Detect, Track, Classify !!!  Operate per sensors  Maneuver to keep on beam Attack  General due to clearances  Preferred firing position  Alertment position
  26. 26. Typical Deployment Cycles SSN – typical 6-9 months SSBN / SSGN - 3 months on / 3 off avg. w/ training and maintenance in between (not set schedule) (Blue & Gold Crews) USS Jimmy Carter - Around 300 days (?)
  27. 27. Future of Submarines SSGN Virginia Class (SSN) Conformal Acoustic Velocity Sonars (CAVES) Unmanned Undersea Vehicles
  28. 28. Questions??
