The fiscal year 1997 DOD procurement appropriation is $43.8 billion, a reduction of over 67 percent from the $134.3 billion (in constant fiscal year 1997 dollars) appropriated in 1985. Many weapon acquisitions have been affected by this decline in the procurement budget. DOD's primary response to the reduced budget has been to reduce annual procurement quantities of weapons in full-rate production and extend their production schedules. DOD buys new weapons in two phases: low-rate initial production (LRIP) and full-rate production. When in LRIP, according to 10 U.S.C. 2400, DOD is to buy minimum quantities of a new weapon. This legislation resulted from concern in the Congress about the large quantities of weapons units bought before adequate testing. The purpose of LRIP is to (1) provide weapons for operational test and evaluation, (2) establish an initial production base for the weapon, and (3) permit an orderly increase in production before full-rate production begins. Operational test and evaluation is key to ensuring that a weapon's capabilities operate as designed before full-rate production begins. At this time, field tests are done to demonstrate the weapon's effectiveness and suitability for military use. After the weapon's design has stabilized and the weapon's capabilities are proven, the services enter full-rate production to begin buying proven weapons in economic quantities. In practice, DOD views low-rate production as any production prior to completion of initial operational tests and full-rate production as the production that follows these tests, with the terms low rate and full rate having little or no relevance to the annual quantity bought. We reviewed 6 weapons in LRIP and 22 weapons in full-rate production. (See app. I for a list of the weapons.) The 22 weapons in full-rate production represent those that in fiscal year 1996 had substantial ongoing production lines. The six low-rate production weapons were ones in production in fiscal year 1996 with substantial planned follow-on full-rate production quantities. For the six weapons in low-rate production, we looked for increases in production rates before operational tests were completed and decreases in the planned future full production rates. For the 22 weapons in full-rate production, we compared DOD's planned optimal production rates, costs, and schedules to that of actual full-rate production through fiscal year 1996 (see app. II). It is not uncommon for DOD to reduce the annual production quantities of proven weapons, stretching out full-rate production schedules for years. For 17 of the 22 proven weapons we reviewed, the actual production rates were 57 percent lower than originally planned. Decreased rates vary from 10 percent for the E-2C Hawkeye to 88 percent for the Standard missile system. For 12 of these weapons with reduced rates during full-rate production, program officials cited insufficient funding as a contributing reason for lower rates, and therefore stretching out production. As a result of reduced rates, production of the 17 weapons will take an average of over 8 years, or 170 percent, longer to complete than originally planned. The number of years the 17 weapons' production schedules have been stretched out ranges from 1 year for the Avenger to 43 years for the Black Hawk helicopter based on current production rates. (See app. III for the reduced production rates on each of these weapons.) Examples of proven weapons with reduced annual production rates follow: At the extreme for slowed production is the Army's Black Hawk helicopter. If the Army continues to buy the Black Hawk at the current rate, full-rate production will take almost 54 years to complete, about 43 years longer than originally planned. The Navy's production of the Tomahawk missile was to be completed in 9 years or by 1992, but instead it will take 15 years or until 1998, a 67-percent schedule increase. Originally, the Navy's planned procurement rate was 600 Tomahawks annually; instead, it has averaged 276 missiles a year, a decrease of over 50 percent from the planned production rate. Because of their reduced annual production rates and stretched out schedules, the acquisition of the 17 weapons we reviewed in full-rate production has cost nearly $10 billion more, through fiscal year 1996, than the program offices estimated based on their original planned production rates. Since 14 of the 17 weapons will still be in production beyond fiscal year 1996, the total increased cost at completion of these weapons could be significantly more than $10 billion. When the annual production quantity of a weapon is reduced, its unit cost generally increases because fixed costs are spread over a smaller quantity. This was the case for 14 of the 17 weapons we reviewed that had reduced production rates (see app. II). For example, the Navy planned to produce 48 T45 training aircraft annually at a unit cost of $8.7 million. Instead, an average of 12 T45s has been produced annually since full-rate production began in 1994, at a unit cost of $18.2 million. For the quantity produced in full-rate production through fiscal year 1996, T45 costs have increased from the original estimate by $345 million. When weapon systems are funded at their planned full production rates or higher, the unit cost of the weapon generally decreases, as illustrated in the following examples: The Army's program office increased the quantities of its Global Positioning System (with an original planned annual rate of 14,000) from 11,000 to 18,500 during 4 years of full-rate production. As a result, the unit cost of the system decreased from $1,400 to $1,076. If annual production were increased, the Army could save up to an estimated $491 million on the remaining 109 Kiowa Warrior helicopters it needs to finish full-rate production. For each of the last 3 years, the program office has procured an average of 16 units a year at a unit cost of $10.22 million. According to Kiowa program officials, the most efficient annual production rate of 72 helicopters would reduce unit cost to $5.72 million. The practice of allocating funds during low-rate production to increase annual production quantities before successful completion of initial operational test and evaluation has frequently been wasteful. As we reported in November 1994, the consequences of buying large quantities of untested weapons are increased acquisition costs, the accumulation of unsatisfactory weapons that require costly modifications to meet performance requirements and, in some cases, the deployment of substandard weapons to combat forces. That report contained 12 illustrative examples describing the problems experienced when the weapons were tested, the major fixes required after significant quantities were bought and, in many cases, the deployment of substandard weapons to combat forces. (Those 12 examples are included in appendix IV of this report.) In one case, before the Army did any operational test and evaluation, a multiyear production contract was awarded for up to 10,843 trucks. Operational testing was suspended 2 months after it began because the trucks were found to be unreliable and therefore not operationally effective. Production continued while the contractor modified the truck design to correct deficiencies. By the time the trucks passed operational testing, over 2,000 trucks were produced, the majority of which required extensive remanufacturing to correct the deficiencies. Most program offices developed an acquisition strategy for both low-rate and full-rate production based on optimistic projections of available funding. As a result, the offices tended to over program the number of weapons that can be bought with the dollars available in DOD's spending plan. As we have previously reported, the use of optimistic planning assumptions has led to program instability, costly program stretch-outs, and program terminations. Current DOD acquisition guidelines permit increasingly higher quantities of weapons in low-rate production to provide for the orderly transition to full-rate production. In addition, DOD's acquisition culture encourages this practice to solidify organizational commitment to keep weapon acquisition programs moving and to protect them from interruption. In this regard, within DOD's acquisition culture, a weapon's acquisition manager's success depends on getting results, and in acquisitions, results mean getting the weapon into production and into the field. The trend to reduce the full production rates from the original plans because of limited funds and to produce more quantities than are needed for testing during low-rate production increases procurement costs. For example, DOD increased the annual low-rate production of the Army's untested Longbow Hellfire Missile in fiscal years 1995, 1996, and 1997 from 0 to 352, and 1,040, respectively; while the Navy reduced full-rate production of the Standard missile system for those fiscal years from 202, to 64, and 127, respectively. Between fiscal years 1995 and 1997, low-rate production funding for the Longbow was increased from $41.2 million to $249.5 million while the full-rate funding for the Standard missile was reduced from $240.4 million to $197.5 million. The Navy originally planned to produce 2,160 Standard missiles a year during full-rate production over a period of 4 years. Instead, the Navy has averaged only 266 missiles a year and at that rate it will take 21 years to complete production, 17 years longer than planned, and at a cost of $286 million more than estimated at the originally planned rate. Many times, the services steadily increased the annual LRIP quantities, exceeding the number ultimately needed to complete operational tests and prove out the production line. The increase in annual quantities of weapons produced during low-rate production resulted in a substantial reduction of funds available for the production of proven weapons at planned rates. By minimizing the quantities of weapons procured during LRIP, DOD can reduce the risk associated with producing untested weapons and increase the funding available to produce other proven systems in full-rate production at planned rates, lowering their unit cost. For eight of the weapons we reviewed, the services' procurement rates during LRIP were equal to or more than they were during full-rate production. For example, the program office for the advanced medium range air-to-air missile increased the quantities produced during low-rate production to 900 units annually. However, since 1992, when it completed operational tests and entered full-rate production, the missile has been produced at an annual rate of 900 or more only twice. In fact, from fiscal years 1997 to 2007, the program office plans to procure an average of only 338 units a year. Table 1 shows the remaining seven weapons with low-rate production quantities equal to or higher than full-rate quantities. DOD continues to generate optimistic full-rate production plans that are rarely achieved. One example where this situation could occur and where planned increases in low-rate production quantities may be unnecessary is the Navy's F/A-18E/F system. The Navy plans to procure 72 F/A-18E/F aircraft over 3 years during LRIP--12 in 1997, 24 in 1998, and 36 in 1999 and then procure 72 each year during peak full-rate production years. However, the Congress has questioned the affordability of this full production rate and has directed DOD to calculate costs based on estimates of 18, 24, and 36 aircraft a year. In addition, the conferees on the Omnibus Consolidated Appropriations Act for Fiscal Year 1997 asked for calculations based on 48 aircraft a year. The increased quantities procured during low-rate production are not necessary to transition to full-rate production, especially if the number of aircraft procured during full-rate production drops significantly. Even if the Navy buys the aircraft at the rate originally planned, production rate increases to reach peak full rates could occur after the system has been operationally tested, rather than before. The same optimistic planning is reflected in the Air Force's F-22 program. The Air Force plans to contract for F-22 aircraft under four low-rate buys of 4, 12, 24, and 36 aircraft for a total of 76 aircraft at an estimated cost of nearly $11 billion prior to completing initial operational test and evaluation and entering full-rate production at 48 aircraft a year. During LRIP, DOD is supposed to restrict the number of weapons produced to the minimum quantity necessary to conduct operational testing, establish the initial production base, and allow for an orderly increase into full-rate production. However, because DOD often budgets available funding for unnecessary increases in low-rate production quantities of unproven weapons, it rarely is able to buy proven weapons at originally planned full-rates. When funding is insufficient to produce proven weapons in full-rate production at optimum levels and therefore to complete programs in a timely manner, it is not cost-effective to use limited funds to unnecessarily increase production of untested weapons whose designs are not yet stabilized. This wasteful practice could be minimized by shifting increases in annual production rates from the low-rate production phase to the beginning of full-rate production. We recommend that the Secretary of Defense revise DOD's weapon acquisition policies to require that (1) annual quantities of weapons bought during LRIP be limited to the minimum necessary to complete initial operational test and evaluation and prove the production line and (2) rates and quantities not be increased during low-rate production to ease the transition into full-rate production unless DOD clearly establishes that the increase is critical to achieving efficient, realistic, and affordable full production rates and can be accomplished without affecting the efficient production of proven systems. We also recommend that the Secretary of Defense direct the Under Secretary of Defense for Acquisition and Technology and the Under Secretary of Defense (Comptroller and Chief Financial Officer) to submit future budgets that place priority on funding the efficient production of weapons in full-rate production. In commenting on a draft of this report, DOD agreed with the principle that premature commitment to LRIP is unwise and that LRIP should not be used to buy equipment that is known not to work. DOD believes the existing policy as set forth in the requirements of 10 U.S.C. 2400 (enacted in 1995) and DOD Directive 5000.2-R (issued in 1996) adequately provides an acquisition structure that allows DOD to focus on minimizing LRIP quantities, while providing the flexibility to maintain an adequate industrial base capability (e.g. ramp-up) to meet the interest of national security. DOD also stated that it makes every effort to fund full-rate production programs to the maximum extent possible within funding availability, changing priorities, and program realities. Concerning our recommendations, DOD commented that (1) its current acquisition policies fully comply with the intent of the policy proposal to minimize the quantities produced under LRIP, (2) increasing production rates (ramping-up) during LRIP allows the contractor to hire and train his production team and maintain a production workforce while operational testing is being conducted, and (3) it makes every effort to fund full-rate production programs but fiscal realities driven by a fluid environment is a serious challenge that will continue to impact the stability of major defense acquisition program production rates and quantities. Although efforts have been made in the last year to reduce the quantities bought under LRIP, our review indicates that DOD is still buying more than the minimum quantities needed. By allowing the ramp-up of quantities under LRIP to hire, train, and maintain a workforce to produce a still unproven product, funding is diverted from contractors producing proven products and their workforce by reducing their production rates and quantities. DOD's comments have not addressed (1) the negative effect of the current approach on the industrial base, (2) the cost implications, and (3) the delayed deployment of proven weapons. Cost implications include the added funding that will be needed to correct the problems in products produced before operational testing is completed and the increased costs from stretching out the production run of proven products. Stretched production schedules can also undermine national security interests by delaying deployment of needed proven systems to field units. If the LRIP rate "ramp-up" was delayed until after the completion of operational test, initial quantities of unproven systems would be reduced and additional funding would become available to buy the proven systems at more efficient rates. Although there are many reasons why weapon quantities and funding for full-rate production should be changed (such as changes in threats and technology), as long as the existing requirement remains valid, we believe priority should be given to funding the already tested, less risky full-rate systems at the most efficient rate possible. DOD's comments are presented in their entirety in appendix V. To quantify the number of weapons being bought below their planned full production rates, we screened the line items contained in the February 1995 Procurement Programs document. We determined that 88 percent of the budget for fiscal year 1996 was concentrated into 300 line items. We then reviewed the 300 line items, primarily using budget back-up books' documentation, to determine which of those items were being bought on an annual repetitive production basis, which is more conducive to increased rate production. We narrowed our universe to 83 line items, or 80 weapons, by excluding line items that were multiple procurement items such as spares, modification programs if the work was being done at a depot, advance procurements, commercial products, and items that did not have a repetitive annual production profile, such as a single one-time procurement. As we obtained additional program-specific data on the 80 weapons, we determined that an additional 52 weapons should be excluded based on the original criteria. Thus, our final universe was 22 weapons in full-rate production and 6 weapons in LRIP with a total cost of about $6.5 billion in fiscal year 1996 procurement funds. We collected cost and schedule data for all 28 weapons through interviews and documents from program officials for each weapon, service- and DOD-level acquisition officials, a DOD Comptroller office official, and a defense contractor. We did our review primarily at the individual program offices responsible for procuring the weapons. We performed our review from August 1995 through November 1996 in accordance with generally accepted government auditing standards. This report contains recommendations to you.

Standard missile Rolling airframe missile (RAM) RAM Guided Missile Launch System (GMLS) The C-17's reliability is significantly less than expected, and the system cannot meet current payload/range specifications. Also, while known problems with the wings, flaps, and slats are being fixed, other problems continue to emerge. (GAO/T-NSIAD-94-166, Apr. 19, 1994). Despite the poor operational, test, and evaluation (OT&E) results, the Air Force continued full-rate production and had acquired about 750 systems at a cost of over $570 million, as discussed in a classified GAO report. All 65 systems were produced under LRIP at a cost of $256 million, before any OT&E was conducted. Because of performance problems, most of the jammers were placed in storage and only 24 were installed on aircraft. One year later, the 24 jammers were deactivated because of poor performance. (GAO/NSIAD-90-168, July 11, 1990). Through 1993, 331 of the 514 planned units were acquired under LRIP. However, the system has encountered significant software problems, which have delayed completion of development testing by about 2 years. OT&E has not yet started. After the Air Force bought most of the total quantity of units under LRIP, tests found serious performance problems. As a result, the system was deployed with the receiver/processor inoperative due to a lack of software. Other deficiencies were also present. (GAO/NSIAD-90-168, July 11, 1990). Before the Air Force conducted OT&E, 72 test sets were procured under LRIP at a cost of $272 million. Later testing showed that the equipment would not meet requirements, and the units were put in storage. Developmental, operational, test, and evaluation (DOT&E) recommended that jammers production be stopped because of poor OT&E results. However, the system had already entered and continued full-rate production anyway. We later found that most of the 24 jammers deployed to a tactical fighter wing had been placed in storage. (GAO/NSIAD-90-168, July 11, 1990). OT&E showed that the F-14D was not sufficiently developed and lacked critical hardware and software capabilities. The program was terminated after 55 units were produced. (GAO/IMTEC-92-21, Apr. 2, 1992). (continued) One year into LRIP, OT&E found that the T-45A was not effective in a carrier environment and was not operationally suitable because of safety deficiencies. Subsequent major design changes have included a new engine, new wings, and a modified rudder. (GAO/NSIAD-91-46, Dec. 14, 1990). The Navy procured and deployed Pioneer as a nondevelopmental item and without testing it. Numerous problems ensued, including engine failures, landing difficulties, and a cumbersome recovery system. Many modifications were required to bring Pioneer up to a minimum essential level of performance. Before the Army did any OT&E, a multiyear production contract was awarded for up to 10,843 trucks. Subsequent OT&E was suspended because the vehicles were found to be unreliable and not operationally effective. However, production continues. (GAO/NSIAD-93-232, Aug. 5, 1993). OT&E showed the system to be not operationally suitable. Despite the need for design modifications to correct reliability and maintainability problems, full-rate production was approved. The following is GAO's comment on the Department of Defense's letter dated December 26, 1996. 1. Appendix IV provides examples that illustrate how buying large quantities of unproven systems during LRIP has been costly. All costs are reported in fiscal year 1996 constant dollars unless otherwise indicated. We have modified the report to recognize the fact that there may be a number of valid reasons for changing the quantities and funding for full-rate production, but if the existing requirement is still valid and everything else is equal, we believe priority should be given to buying the proven systems over the unproven.

Summary:
GAO reviewed the Department of Defense's (DOD) weapons acquisition procedures, focusing on: (1) DOD's practice of reducing the annual production of weapons below planned optimum rates during full-rate production; (2) the reasons for this practice; and (3) the effect of this practice on the costs and availability of weapons. GAO found that: (1) DOD has inappropriately placed a high priority on buying large numbers of untested weapons during low-rate initial production to ensure commitment to new programs and thus has had to cut by more than half its planned full production rates for many weapons that have already been tested; (2) this practice is wasteful because DOD must often modify, at high cost, the large numbers of untested weapons it has bought before they are usable and must lower annual buys of tested, proven weapons, stretching out full-rate production for years due to a lack of funds; (3) GAO has repeatedly reported on DOD's practice of procuring substantial inventories of unsatisfactory weapons requiring costly modifications to achieve satisfactory performance and, in some cases, deployment of substandard weapons to combat forces; (4) GAO found the practice of reducing planned full production rates to be widespread; (5) primarily because of funding limitations, DOD has reduced the annual full-rate production for 17 of the 22 proven weapons reviewed, stretching out the completion of the weapons' production an average of 8 years longer than planned; (6) according to DOD's records, if these weapons were produced at their originally planned rates and respective cost estimates, the quantities produced as of the end of fiscal year 1996 would have cost nearly $10 billion less; (7) at the same time, DOD is funding increased annual quantities of weapons in low-rate production that often are in excess of what is needed to perform operational tests and establish the production base; (8) if DOD bought untested weapons during low-rate initial production at minimum rates, more funds would be available to buy other proven weapons in full-rate production at more efficient rates and at lower costs; and (9) this would reduce costly modifications to fix substandard weapons bought in low-rate production and allow full-rate production of weapons with demonstrated performance to be completed and deployed to combat forces earlier.
