CG-47 Ticonderoga
Modern US Navy guided missile cruisers perform primarily in a Battle Force
role. Due to their extensive combat capability, these ships have been
designated as Battle Force Capable (BFC) units. Their primary armament is the
Vertical Launching System (VLS) employs both the long range
surface-to-surface Tomahawk Cruise Missile and the Standard Surface-to-Air
Missile. These multi-mission ships are capable of sustained combat operations
in any combination of Anti-Air, Anti-Submarine, Anti- Surface, and Strike
warfare environments. They are built to be employed in support of Carrier
Battle Groups, Amphibious Assault Groups, as well as interdiction and escort
missions.
The Ticonderoga class, using the highly successful Spruance hull, was
initially designated as a Guided Missile Destroyer (DDG), but was
redesignated as a Guided Missile Cruiser (CG) on January 1, 1980. The
Ticonderoga class were the first surface combatant ships equipped with the
AEGIS Weapons System, the most sophisticated air defense system in the world.
Technological advances in the Standard Missile coupled with the AEGIS combat
system in Ticonderoga class cruisers and the upgrading of older cruisers have
increased the AAW capability of surface combatants. The heart of the AEGIS
system is the SPY-1A radar, which automatically detects and tracks air
contacts to beyond 200 miles. The AEGIS Weapons System is designed to defeat
attacking missiles and provide quick reaction, high firepower, and jamming
resistance to deal with the Anti-Air Warfare threat expected to be faced by
the Battle Group.
Twenty-two TICONDEROGA-class AEGIS cruisers, starting with CG-52, have
vertical launch systems (VLS) which permit them to carry and launch
significant numbers of TOMAHAWK precision strike cruise missiles against
targets of military importance deep in enemy territory. This land attack
capability, coupled to their AEGIS anti-air missile systems, AN/SQQ-89
Undersea Warfare system and sophisticated C4ISR suite, make these ships the
most powerful surface combatants in service with any navy.
A new modernization plan for surface combatants would decommission some ships
early, but would boost the firepower of the remaining force by adding the
Vertical Launch System (VLS). The five TICONDEROGA-class cruisers in the
fleet without VLS would receive the system: USS TICONDEROGA (CG 47), USS
YORKTOWN (CG 48), USS VINCENNES (CG 49), USS VALLEY FORCE (CG 50) and USS
THOMAS GATES (CG 51).
The Ticonderoga class also brings a multi-warfare capability to the Fleet
which significantly strengthens Battle Group operation effectiveness,
defense, and survivability. The cruisers are equipped with Tomahawk ASM/LAM
giving them additional long range strike mission capability. The addition of
Tomahawk ASM/LAM in the CG-47 class has vastly complicated unit target
planning for any potential enemy and returned an offensive strike role to the
surface forces that seemed to have been lost to air power at Pearl Harbor.
Two five-inch gun mounts are used against threatening ships and boats,
low-flying aircraft, or to bombard shore targets. In addition, the ships
carry a strong Anti-Submarine Warfare Suite and the Navy's latest Electronic
Warfare Suite is also aboard. The cruisers have the most advanced underwater
surveillance system available today. The Anti-Submarine Warfare (ASW)
equipment consists of a hull-mounted SONAR, an Acoustic Array SONAR which is
towed like a tail behind the ship, and a helicopter that can locate ships or
submarines over 100 miles away.
The "Tico" cruisers, using the SPRUANCE Class hull, measure 567 feet from bow
to stern. Their beam is 55 feet, and displacement is 9,600 tons. Four
powerful gas turbine engines propel the ships to speeds greater than 30
knots, and two controllable-reversible pitch propellers assist in rapid
acceleration and maneuverability.
Authorized in Fiscal Year 1978, TICONDEROGA's keel laying ceremony occurred
on 27 January 1980. The first five Ticonderoga-class cruisers⑳iconderoga
(CG-47) through Thomas S. Gates (CG-51)锝ave an early, less capable version
of the Aegis combat system and do not have VLS or the capability to launch
Tomahawk cruise missiles. Also, the first two ships of the class have two
SH-2F helicopters instead of the SH-60B helicopter employed on later
cruisers. The guided missile cruiser Port Royal (CG 73) was comissioned on
Saturday, July 9, 1994. Port Royal was the last of 27 Ticonderoga class Aegis
guided missile cruisers scheduled to be built. These new cruisers have
replaced older, less capable ships that are being taken out of service as
part of the Navy's overall plan to recapitalize the fleet.
These ships were built in sections, called modules, which allowed improved
access to all areas of the ship during construction. The modules were then
moved together to form the hull of the ship, and the deckhouse sections were
then lifted aboard. For launching, the ship was moved several hundred yards
across land to the floating dry dock, which was used to actually launch the
ship.
During their construction, hundreds of subassemblies were built and outfitted
with piping sections, ventilation ducting, and other shipboard hardware.
These subassemblies were then joined to form modules, which were then
outfitted with larger equipment items, such as propulsion and power
generation machinery and electrical panels. This represents an advancement
from traditional shipbuilding in which these systems are installed in tight
quarters below decks after the hull is completed. At Ingalls, four of these
pre-outfitted hull and superstructure modules are joined together to form the
ship shortly before it is moved to the water's edge and launched.
At the shipyards, this modular process is supported by an extensive Computer-
Aided Design (CAD)/Computer-Aided Manufacturing (CAM) program that has
significantly enhanced the efficiency of detail design, and has reduced the
number of manual steps involved in converting design drawings to ship
components. The three-dimensional CAD system is linked with an integrated CAM
production network of computers throughout the shipyard. The CAD system
directs the operation of numerically-controlled manufacturing equipment used
to cut steel plates, cut and bend pipe, and form sheet metal assemblies.
Launching involved movement over land via a wheel- on-rail transfer system
onto the shipyard launch and recovery dry dock, which is was ballasted down
in order for the ship to float free and moved to an outfitting berth in
preparation for the traditional christening ceremony. Upon completion of
post-launch outfitting, the cruisers went through an extensive dockside and
at-sea testing period to ensure the ship and crew were ready to safely go to
sea.
The Smart Ship Project was initiated by an October 1995 brief from the Naval
Research Advisory Committee (NRAC) panel on reduced manning to the Chief of
Naval Operations. Their report stated that the major obstacle to reduced crew
size and decreased life cycle costs aboard Navy ships was culture and
tradition rather than the lack of proven technology and know-how. The
challenge was to demonstrate in an operational ship that reductions in
workload and crew requirements were possible while maintaining mission
readiness and safety. The Commander, Naval Surface Force, US Atlantic Fleet
(COMNAVSURFLANT) was designated as Executive Agent for the Smart Ship Project
and nominated USS YORKTOWN (CG 48) as the ship in which to implement ideas to
demonstrate the concept.
SMART SHIP "CORE TECHNOLOGIES"
Integrated Bridge System (IBS): automated piloting, ship旧 course and track
analysis with radar and chart overlay, including collision avoidance.
Integrated Condition Assessment System (ICAS): automated condition-based
maintenance recorder for main propulsion and auxiliary equipment; digital
information maintained on fiber optic LAN.
Damage Control Quarters (DCQ): automated damage control management system
providing information and communication throughout the ship on the fiber
optic LAN.
Machinery Control System (MCS): automated digital propulsion and electrical
plant control using signals passed via the fiber optic LAN.
Fuel Control System (FCS): automated digital control of ship旧 fuel transfer
system.
Wireless Internal Communication System (WICS): individual ship旧 company
personal communications or near the ship.
Fiber Optic Ship Wide Area Network (FO SWAN): fiber optic LAN hosting the
above listed core technologies (vice the WICS) utilizing asynchronous
transfer mode (ATM) and being IT 21 compliant
All approved Smart Ship initiatives were implemented aboard YORKTOWN prior to
her deployment in December 1996. Huge chunks of the ship were torn up and
thrown away and replaced by computer consoles and miles of fiber optic cable.
A local area network was installed, bringing greater versatility in
communications and training. Smart Ship Inovations allowed the bridge team to
go from 13 personnel on watch at a time down to 3.
Smart Ship inovations allowed the Engineering team more flexablility in the
operation of the engineering plant. It has also allowed the engineering
Central Control Station to go from 11 people on watch at one time down to 4.
With all policy and procedure, technology, and maintenance initiatives
implemented, crew reductions enabled by the decrease in workload were 44
enlisted personnel and 4 officers The Smart Ship Project demonstrated that
shipboard workload reductions are possible while maintaining combat readiness
and safety with significant net positive return on investment. Expenditures
on available technology and implementation of policy and procedure changes
make crew size reductions achievable. The required expenditures for such
changes are offset by large potential savings, both shipboard and ashore, and
in operations and maintenance costs aboard ship. Technology, taken as a
single package as installed in YORKTOWN, returns the investment in seventeen
years. However, some of the individual technologies demonstrate a more
positive return-on-investment.
In the Fall 1998 USS THOMAS S. GATES (CG 51) was scheduled as the first
installation ship in the US Navy's Integrated Ship Controls (ISC) Program.
This upgrade program will install innovative labor and cost savings
initiatives on USS THOMAS S. GATES, USS TICONDEROGA (CG 47), USS VINCENNES
(CG 49) and USS VALLEY FORGE (CG 50). Many of the technologies to be
installed are the result of the initiatives proven sucessful on YORKTOWN. The
upgrade program also includes options to install systems on the remaining 22
CG 47 Class AEGIS Cruisers. Modernization of the machinery control system for
CG 47 Class ships is required in order to overcome impending obsolescence,
reduce operating and support costs, and facilitate workload reductions. This
will be accomplished with the installation of commercial
off-the-shelf/non-developmental items (COTS/NDI).
The Aegis Cruiser force will remain on the front line into the 21st century,
with upgrades as part of the Cruiser Conversion program. This conversion
program will ensure the relevance of these ships in the future. Without this
program, their future is tenuous. In the program, the modernized combat
system will address the growing theater ballistic missile threat by
incorporation of area and theater-wide TBMD capability. Additionally,
introduction of two five inch 62 caliber guns with extended range guided
munitions in 22 of these ships will help meet the USMC requirements for fire
support. They will continue to receive upgrades to their command and control
suites to ensure they remain full participants in the joint battlespace. This
conversion program takes advantage of the sizable investment ($22B) already
made in these ships, and keeping them ready to meet the challenge over 40
years of service life. It is important to note that the first five AEGIS
cruisers (CG47 ? CG51) are not part of the Cruiser Conversion program because
of affordability.
