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
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
Support of Surface Units
• Highly capable surface and
subsurface interdiction platform
• 20% of CSG Tomahawk firepower
• Mine detection by UUV’s and
acoustics
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 6-9 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 (?)
Future of Submarines
SSGN
Virginia Class (SSN)
Conformal Acoustic
Velocity Sonars
(CAVES)Unmanned Undersea Vehicles
