The Ticonderoga (CG 47) - Class

CG 66 and CG 69 inport Kiel, Germany

The TICONDEROGA - class consists of the 27 most expensive cruisers and the most powerful surface combatants in service in the world. The high price of about $1 billion is a result of the AEGIS Combat System.

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) which is able to employ 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.

TICONDEROGA class cruisers are named after famous American Battles (with the exception of USS THOMAS S. GATES).

The development of this class started in the 1970th. Initially designated as Guided Missile Destroyers (DDG), the TICONDEROGAs were redesignated as Guided Missile Cruisers (CG) on January 1, 1980. The hull and the propulsion system of the SPRUANCE class were the basis for this new class of guided missile ships but AEGIS and numerous other installations caused an increase of the displacement of almost 1,000 tons.

The TICONDEROGA - class cruisers 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 and the vertical launch systems (VLS) which permits these ships to carry and launch significant numbers of TOMAHAWK precision strike cruise missiles against targets of military importance deep in enemy territory, make these ships the most powerful surface combatants in service with any navy.

During the construction of the SPRUANCE class destroyers there was a contract that Ingalls had to deliver the ships ready for commissioning. That meant that all combat systems were ordered and installed by Ingalls. During the construction of the TICONDEROGA class the Navy has been more active. The Navy helped with the blueprints and was responsible to provide the Combat Systems.

The first cruiser, the TICONDEROGA, was ordered and authorized in FY 1978.

The first five ships don't possess the power of the final units. The main reason for this deficit is the MK 26 launcher instead of the MK 41 VLS. MK 26 is not able to launch TOMAHAWK cruise missiles. They also possess a less capable version of the AEGIS system and CG-47 and CG-48 are only equipped with LAMPS I helicopters.

Early plans considered to decommission these five ships, equip them with VLS and re-commission them to adapt them to the standard of the later ships. However, in 2003, the Navy decided to upgrade only 22 of the 27 ships (CG 52 - CG 73), in an effort to keep these ships combat-relevant until a new generation of surface warships can be designed and built. This conversion will give the ships a service life of 35 years each. The conversion will also allow the ships to participate in land attack, littoral undersea warfare, force protection and anti-air defense missions, including ballistic missile defense. The first ship scheduled to go through the conversion is the CAPE ST. GEORGE (CG 71) starting in 2006. The final ship will begin conversion in 2014.

There are varying capabilities between Baselines 2, 3 and 4. The cruiser conversion program will result in all 22 ships having a common baseline. The core components of the combat systems cruiser conversion include:

Also included in the conversion is the “all-electric modification” which will eliminate waste heat boilers and associated equipment, replace steam-operated equipment with electric equipment - including laundry washers and dryers, galley kettles, dishwashers, lubrication and fuel oil heaters and potable water heaters with equivalent electrical equipment. It will replace flash type distilling plants with reverse osmosis units capable of treating potable water. The reverse osmosis units are easier to maintain, more reliable and do not create high temperatures in the work spaces, which reduces heat stress and improves shipboard quality of life.

CG 47 - CG 51 will not receive the conversion and will be decommissioned by 2006, starting with the TICONDEROGA (CG 47) in 2004.

About the Construction of the Ships:

The ships of the TICONDEROGA - class 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 were joined together to form the ship shortly before it was 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 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.

About the Smart Ship Project:

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":

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.

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.

The Baselines of the Ticonderoga class
Baseline 0
USS Ticonderoga (CG 47)
USS Yorktown (CG 48)
CG 47 and 48 have the basic Aegis Mk 7 system, with SPY-1A, Weapons Control System Mk 1, Standard SM-2 MR Block I missiles, and the Mk 116 Mod 4 UBFCS. These first two ships of the class initially only operated two SH-2F LAMPS-I helicopters instead of the SH-60B helicopter employed on later cruisers. Appearently, both ships were later modified to operate the SH-60B helicopters also. These two ships used UYK-7 computers. Both have since had their combat systems updated to Baseline 1 status but do not carry towed sonar arrays. Both will have their electronic engineering systems updated to reduce maintenance costs. They are to be updated by builder with Mk 41 vertical missile launch groups in place of the Mk 26 launchers; 62-caliber, extended-range 5-inch guns in place of the Mk 45 mountings; UYK-43 computers in place of the UYK-7 and UYK-20 set; and upgraded weapons control and communications suites.
Baseline 1
USS Vincennes (CG 49)
USS Valley Forge (CG 50)
USS Thomas S. Gates (CG 51)
The first five Ticonderoga-class cruisers Ticonderoga through Thomas S. Gates - have an early, less capable version of the Aegis combat system and do not have VLS or the capability to launch Tomahawk cruise missiles. On CG 47-51, each Mk 26 Mod 1 missile-launcher magazine holds 44 missiles; the forward magazine formerly also held 20 ASROC. For Baseline 1 the RAST haul-down and deck-maneuvering system and SQQ-28 helicopter datalink were added for SH-60B LAMPS-III helicopters, SM-2 MR Block II missiles were carried, the Aegis system has improved data displays, and the EW suite was enhanced. Both masts are tripods vice quadripods. These units are to have their electronic engineering systems updated to reduce maintenance costs, the twin Mk 26 missile launchers are to be replaced by Mk 41 vertical launch groups, and the combat systems are to be updated as in the Baseline 0 pair.
Baseline 2
USS Bunker Hill (CG 52)
USS Mobile Bay (CG 53)
USS Antietam (CG 54)
USS Leyte Gulf (CG 55)
USS San Jacinto (CG 56)
USS Lake Champlain (CG 57)
USS Philippine Sea (CG 58)
Baseline 2 consists of the Vertical Launching System, TOMAHAWK Weapon System, and Anti-Submarine Warfare upgrades. The Mk 41 Mod 0 VLS was substituted for the Mk 26 twin-armed launchers and a vertical-launch Tomahawk capability with SWG-3 launch control system was added, as were an improved Link 11 and UYQ-21 displays. CG 52 Bunker Hill was the first unit to feature the revolutionary Vertical Launching System (VLS), a multi-warfare launcher designed to meet the threat of today and the future - well into the 21st century. CG 52 with her VLS offers critical advantages to meet those challenges: larger magazine capacity, higher rate of fire, rapid weapon selection, 360 degree coverage, lower power requirements and higher survivability. VLS can accommodate a variety of missile types. All missiles are stowed vertically in corrugated steel canisters and fired straight-upward in rapid succession. CG 52 has a total VLS capacity of 122 missiles, 61 per launcher. The ship can fire a multiple assortment of air, surface and land attack missiles. Congress initially mandated the omission of SPS-49 radars and the SQQ-28 LAMPS-III datalink in CG 54-56, but gave permission in 1984 to add the equipment. CG 54 and 55 had stand-alone SQR-19 towed sonar arrays and SQS-53A. CG 53 and later substituted a 24 ft Rigid Inflatable Boat (RIB) for the 26 ft motor whaleboat. CG 56 introduced the SQQ-89(V)3 integrated ASW suite, with SQS-53B sonar, SQR-19 towed array, and the Mk 116 Mod 6 UBFCS. All are planned to be updated by 2003 to perform Theater Ballistic Missile Defense (TBMD) missions and to employ the Cooperative Engagement Capability (CEC), at a total cost of $137 million. The electronic engineering systems are also to be updated.
Baseline 3
USS Princeton (CG 59)
USS Normandy (CG 60)
USS Monterey (CG 61)
USS Chancellorsville (CG 62)
USS Cowpens (CG 63)
USS Gettysburg (CG 64)
Baseline 3 includes the AN/SPY-1B radar and AN/UYQ-21 consoles. The lighter SPY-1B radar, with improved radiating characteristics, was substituted for SPY-1A, and new computers (UYK-43 and UYK-44 in place of UYK-7) are employed. CG 59 was the Navy's first cruiser equipped with the AN/SPY-1B radar system, which provided a significant improvement in the detection capabilities of the AEGIS Weapons System. This radar system incorporates significant advances over earlier radars, particularly in its resistance to enemy Electronic Countermeasures (ECM). With the SPY-1B radar and the ship's MK 99 Fire Control System, the ship can guide its Standard Missile to intercept hostile aircraft and missiles at extended ranges. In 1996, CG 61 became the first of this group to be upgraded with the SPY-1D(V) radar and received a combat system upgrade including all-new combat system computers, consoles, and displays. The upgrade will permit future installation of such planned upgrades as Cooperative Engagement Capability, Theater Ballistic Missile Defense capability, and new versions of the Standard missile.
Baseline 4

USS Chosin (CG 65)
USS Hue City (CG 66)
USS Shiloh (CG 67)
USS Anzio (CG 68)
USS Vicksburg (CG 69)
USS Lake Erie (CG 70)
USS Cape St. George (CG 71)
USS Vella Gulf (CG 72)
USS Port Royal (CG 73)

Baseline 4 integrates the AN/UYK-43/44 computers (in place of UYK-7 and UYK-20) with superset computer programs developed for the DDG 51. CG 65-73 have the improved UYS-20 data display system and various decision aids. All ships of the group had the SQS-53C sonar and the SQR-17 sonar data processor.
