24. 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
25. 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
26. Support of Surface Units
• Highly capable surface and
subsurface interdiction platform
• 20% of CSG Tomahawk firepower
• Mine detection by UUV’s and
acoustics
32. Submarine Tactics:
Localization
Detect, Track, Classify !!!
Operate per sensors
Maneuver to keep on beam
Attack
General due to clearances
Preferred firing position
Alertment position
33. 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 (?)
34. Future of Submarines
SSGN
Virginia Class (SSN)
Conformal Acoustic
Velocity Sonars
(CAVES)
Unmanned Undersea Vehicles
Fast Attack submarines can go on 6 month deployments and are stand by for whenever they need to be called.
Older Class Submarines include the Sturgeon Class (SSN)
There are two Los Angeles Class Submarines one is an improved version of the other.
Lead Number SSN 688 (52+10)
I believe the new version lead number is the SSN 774, Virginia Class.
Sonar is active and passive
Lead Number SSN 21 (2)
Towed Arrays: 1 surveillance, 1 tactical
D5 Missiles are the current version. More accurate, powerful, and with longer range.
Protects surface units from underwater threats
UUV – Mine detection, sea floor mapping, danger areas
CAVES – More compact sensors that can be placed all over the ship for wider acoustic range
Current: 11 up 53 down - baffles
