THE GUIDED MISSILE FRIGATE (DLG) ANTI-AIR WARFARE MODERNIZATION PROGRAM
PROGRAM DESCRIPTION AND STATUS
All ships are being equipped with an improved three-dimensional air search radar, an improved guided missile fire control system, and the Naval Tactical Data System. Changes are also being made to improve the communications system, increase the anti-submarine detection capability, and to increase the electrical generating and air-conditioning capacities. In addition to modernizing the ships, needed repairs and rehabilitation are being made to ship structures and equipment.
As of June 30, 1972, four DLG-6 class ships and six DLG-16 class ships had completed the modernization program. Another two DLG-6 class ships and the remaining three DLG-16 class ships were in various phases of the program. These five ships are scheduled to complete modernization during the period of October 1972 to March 1974.
The first of the remaining four ships of the DLG-6 class started the program in October 1972 and modernization of all four ships is scheduled for completion by March 1976. The DLG(N)-25 is scheduled to start in June 1974, and be completed in October 1976.
PROGRAM COST EXPERIENCE
The cost changes for this program are shown in the following table:
Amount (In Millions) | ||
---|---|---|
June 30, 1971 Estimate | $ 1,006.6 | |
Changes during fiscal year 1972 | ||
Engineering Change | (+) 7.7 | |
Support Change | (+) 1.3 | |
Economic Change | (+) 4.6 | |
Estimating Change | (+) 1.8 | |
Other Changes | (-) 1.4 | (+) 14.0 |
Program Costs as of June 30, 1972 | $ 1,020.6 |
- $6.4 million for removing the 3-inch guns and installing the Close-In Weapon System and other equipment
- $1.1 million for computer software for the Naval Tactical Data System.
The net increase of $1.3 million in support costs represents a number of adjustments pertaining to outfitting requirements for various ships.
Of the $4.6 million in increased economic costs, $4 million represents expected higher labor rates t material costs t and escalation for the DLG~l0 and DLG(N)-25 ships. The remaining $.6 million resulted from higher escalation costs and repair labor rates experienced on two of the completed ships.
Estimating changes resulted in a net increase of $1.8 million. The increase is a combination of
- A reinstatement of $3.6 million in fiscal year 1972 post-delivery funds that had been deleted in a prior year
- A net decrease of $1.8 mi1lion t primarily in the cost estimates for the DLG-10 and DLG(N)-25 ships due to updated cost information
A decrease of $1.4 million in other changes is a combination of a $4.1 million cost under-run and an increase of $2.7 million, primarily for radar equipment for the DLG-11 which had not been charged to the program.
Information provided by Office of the Secretary of Defense from the Congressional Data Sheets shows the current estimate through completion of this system as of December 3l t 1972 t to be $l t 010.4 million. The $10.2 million decrease from the June 30, 1972, amount can be attributed to a reevaluation of Post Delivery equipment.
Economic Escalation
Logistics Support/Additional Procurement Costs
Program Funding
Funds programmed as of June 30, 1972 are as follows:
Fiscal Year 1972 and Prior Years | Fiscal Year 1973 | |
---|---|---|
Development | $ - | $ - |
Procurement | $713.4 | $148.4 |
Construction | $ - | $ - |
Total | $ 713.4 | $ 148.4 |
Amount actually appropriated by the Congress for this program was $101.4 million. The change occurred because funding for the DLG-11 was postponed until fiscal year 1974. |
CONTRACT DATA
The contract with Bath provides for modernizing eight ships at a fixed price of $54.4 million (plus escalation) and repairing them at prices to be negotiated on a repair order basis. As of June 30, 1972, there were 150 changes to the scope of the modernization work at an estimated cost of $8.3 million. With respect to repairs, that have been 3,980 repair orders issued at an estimated cost of $49.9 million.
The modernization and repair work at the Philadelphia Naval Shipyard is done on a cost-reimbursable basis. Currently, seven of the ten DLG-6 class ships and the one DLG-16 ship had completed or were undergoing work. The following schedule summarizes costs for modernization and repairing them as of June 30, 1972:
Initial Cost estimates | $ 166.2 million |
Change order issued (155) | $ 3.7 million |
Other Costs (includes escalation, overtime, and increased repairs) | $25.6 million |
Total | $ 195.5 million |
The progress reporting plan for the Bath Iron Works Corporation and the Philadelphia Naval Shipyard consists of the submission of the following types of reports:
- Status of significant industrial milestones
- Labor progress curves
- Test memorandum status
- Erection schedules
- Material status reports.
PROGRAM PERFORMANCE EXPERIENCE
The operational and technical characteristics of the DLG(N)-25 were approved during fiscal year 1972. As compared to the tentative characteristics reported in the June 30, 1971, SAR the more significant changes are the replacement of the ship's 3-inch guns with the Close-In Weapons System and an increase in the ship's cruising range. It will also be equipped with antisubmarine capabilities above those of the other ships in the program
The only characteristic change made in fiscal year 1972, will provide increased air search capability to the last four DLG-6 ships to be modernized. This capability will also be given to the DLG(N)-25.
PROGRAM SCHEDULE EXPERIENCE
We reported in our March 1972 study that the DLG(N)-25 had experienced a 12-month delay in the start of its modernization work. During this review, we noted that the ship start date has been delayed an-additional three-months. This is due to the ship's nuclear engine's ability to operate longer than anticipated before replacement.
The two DLG-6 ships completing the program in fiscal year 1972, completed the program 3 to 4 months later than expected. The delays were primarily caused by engine auxiliary exhaust problems and high fire room temperatures encountered during final contract trials. These problems were subsequently corrected.
RELATIONSHIP TO OTHER SYSTEMS
The 10 DLG-6 class ships have one Terrier launcher as do the DLG-26 through 34 and DLG(N)-35 ships. The DLG-16 class ships and the DLG(N)-25 have two Terrier launchers. The Standard Missile is currently being deployed on the modernized DLG's. The Tartar weapon system will be deployed on the five nuclear frigates expected to be delivered to the Navy by 1978.
