                  The Honorable William V. Roth, Jr.
                  United States Senate
                  Dear Senator Roth:
                  As you requested, we evaluated cost, schedule,and test plans for the
                  Army’s special operations forces (SOF) helicopter program. Specifically,
                  we reviewed (1) the Army’s planned concurrency of prototype and oper-
                  ational testing with helicopter production and (2) current cost estimates
                  for the program.

                  The Army plans to award full-rate production contracts for SOF helicop-
Resultsin Brief   ters before it completesdevelopmental testing and long before it com-
                  pletes operational testing. In fact, the Army plans to have about
                  90 percent of its SOF helicopters either delivered or in production before
                  the completion of operational testing.

                  The Army’s current acquisition strategy for SOF helicopters increasesthe
                  risk of having to make expensive retrofits on production helicopters to
                  correct deficiencies identified in testing rather than limiting the risk to
                  only those systems produced in a low-rate initial production run. Fur-
                  ther, the Army plans to field these systemswithout an important self-
                  defensecapability required for certain missions.
                  The Army currently reports total SOF helicopter modification program
                  costs at about $1.36 billion. However, a more accurate estimate of the
                  cost is at least $2.1 billion becausesomecomponent and airframe costs
                  are being reported and paid for by Army activities other than the SOF
                  product office. In addition, many other costswere not included in the
                  Army’s estimate. Furthermore, this estimate doesnot include the added
                  costs of installing additional equipment after the helicopters are fielded
                  and of overcoming problems identified during testing.

                  The Army initiated SOF modification programs in 1986 for someof its
Background        CH-47 Chinook and UH-60 Black Hawk helicopters. Operationally, these
                  modified aircraft, designatedthe “MH-47E” and the “MH-6OK,” are
           Y      expected to be able to perform clandestine, deep-penetration airlift mis-
                  sions in adverse weather conditions and high-threat environments.



                  Page 1                             GAO/NSIAD-DO-267   Army SOF Helicopter   Program
                        Appendix I provides greater detail on the modifications being made to
                        the Chinooks and Black Hawks to convert them to SOF aircraft.
                        Believing that both the MH-60K and the MH-47E helicopters were
                        nondevelopmental items, the Army originally decided that little heli-
                        copter developmental testing and no operational testing were needed.In
                        its 1989 statement of its SOF helicopter acquisition strategy, the Army
                        assumedthat becausethe helicopters used in the program were quali-
                        fied systems,planned testing and evaluation would consist primarily of
                        integrating and testing already qualified components.Recently, how-
                        ever, the acquisition and testing strategies for both helicopters have
                        been restructured to include additional developmental testing and evalu-
                        ation of the prototype aircraft. The Army believesthat current SOF pro-
                        gram cost and performance risks are acceptable.

                        Although the Army has designatedthe SOF aircraft as nondevelopmental
                        items, the SOF modifications include an extensive integration of both off-
                        the-shelf and newly developed avionics equipment. More specifically,
                        the Army plans to combine about 40 piecesof communications, naviga-
                        tion, and aircraft survivability equipment into the integrated avionics
                        subsystem in the SOF aircraft. In addition, the Army plans to integrate a
                        multimode radar, a forward-looking infrared sensorsystem, a map dis-
                        play generator, and an aviator’s night vision imaging system. According
                        to independent Army evaluators, it is the extensive integration of avi-
                        onics equipment that puts the SOF aircraft at risk.

                        In addition to producing one prototype helicopter for each program, the
                        Army plans to award a series of contracts for the production of
                        60 MH-47E and 22 MH-6OKhelicopters between fiscal years 1990 and
                        1993. Of these, the Army has designatedthe first 11 MH-47E and
                        11 MH-6OKhelicopters as low-rate initial production helicopters.

                        Department of Defenseand Army regulations call for operational testing

                        need for this testing. In the SOF program, however, the Army doesnot
                        plan to conduct initial operational test and evaluation before proceeding
                        beyond low-rate initial production. Rather, under current Army plans,
           I            most SOF aircraft (63 of the planned 74) will be in production or deliv-
                        ered before operational tests even begin. Further, the Army plans to test
                        and field SOF helicopters that do not possessall the equipment necessary
                        to satisfy operational capability requirements.

Risks                      that low-rate initial production may be conductedto verify production
                           capability and to provide the assetsnecessaryto conduct various types
                           of testing, including operational testing. These regulations also require
                           that before the full-rate production decision, initial operational test and
                           evaluation on a production-representative system must be conducted,
                           with a dedicated phase of initial operational test and evaluation on a
                           system certified as ready for fielding.
                           When the Army doesnot follow operational testing requirements, it
                           risks fielding systemsthat require expensive retrofits or are unable to
                           perform their required missions. For example, in 1986, we reported that
                           the Army had little performance information available on the Sergeant
                           York air defensegun to measureits reliability, maintainability, and
                           effectiveness before production began.The acquisition and testing plan
                           for the SergeantYork was similar to that of the SOF helicopter program
                           in that critical operational test information about the ability of the Ser-
                           geant York to perform its mission under realistic conditions was unavail-
                           able prior to the production decision. The Army judged both
                           performance and cost risks on the SergeantYork to be acceptable,based
                           on the use of mature componentsand subsystemsand contractor
                           responsibility and experience.Thus, with only limited test results, pro-
                           duction began on an unproven system. However, the system integration
                           processproved more difficult than expected.When operational testing
                           was eventually conducted,the SergeantYork was unable to perform as
                           intended, and the Secretary of Defenseconsequently terminated the
                           program.


Army Plans Production      The Army plans a low-rate initial production of 22 SOF helicopters
Concurrent With            (30 percent of the total helicopter buy) concurrent with developmental
                           testing on the prototype aircraft. The Army also plans to award full-rate
Developmental Testing      production contracts for both helicopters nearly 2 years prior to the
and Before Operational     completion of the developmental testing of the prototype helicopters
Testing                    and over a year earlier than planned operational testing is to begin. Over
                           90 percent of the 72 MH-47E and MH-6OKproduction helicopters are to
                           be in production or delivered by the time operational testing is to be
                           completed.

                                 sive capability for the helicopter when it is performing certain missions.
                                 Without the missile, there is little to protect these helicopters if they are
                                 discovered by the enemy while on such missions. Neither the missile nor
                                 the recorders have been developed,but the Army plans to incorporate
                                 both items into the helicopters at a later date through preplanned
                                 product improvements.


Army Has Identified Some The Army has identified four areasof risk associatedwith the SOF heli-
Program Risk             copter program: (1) the development of the Integrated Avionics Sub-

                                 qualification of the multimode radar system, (3) the performance of
                                 government-furnished equipment, and (4) retrofit costs for four helicop-
                                 ters in production during contractor flight testing and government pre-
                                 liminary airworthiness evaluation flight tests.

                                 While the Army has identified these areas of risk, it has not addressed
                                 the risk associatedwith concurrent production and government develop
                                 mental and operational testing. On the contrary, Army officials told us
                                 that delaying a full-rate production decision until after the completion
                                 of operational testing would result in cost increasesfor MH-47E aircraft.
                                 They believe that costswould increasebecauseMH-47E and other modi-
                                 fications would have to be made after the CH-47Dproduction line is
                                 closed.

                                 Operational testing of the MH-47E is expected to be completed in Feb-
                                 ruary 1993. At that time the Army will have 32 CH-47Daircraft in pro-
                                 duction. As we reported in February 1990, the Army doesnot have a
                                 mission-basedjustification for 34 of the 61 MH-47E aircraft it plans to
                                 procure.’ Therefore “E” modifications could be made to 16 of the
                                 32 CH-47D aircraft still in production after the completion of opera-
                                 tional testing and before the closeof the CH-47Dproduction line.

                                      CTotalof $195.20 million in cost increases not included in the Army’s current estimate (a).

                                      The Army’s current unit cost estimate, including research,development,
                                      test, and evaluation plus procurement for 51 MH-47E helicopters, is
                                      $17.4 million. The Army estimates a $20.3 million unit cost for
                                      23 MH-6OKhelicopters. Using our estimate of total program costs shown
                                      above,these unit costs are more likely to be $27.2 million for the
                                      MH-47E, or $9.8 million more than the Army’s estimate, and $30.8 mil-
                                      lion for the MH-GOK,or $10.5 million more than the Army’s estimate.

                                      helicopters. Further, additional cost growth is anticipated for the
                                      MI-I-6OK.The Army’s required operational capabilities documents for
                                      SOF helicopters state that the SOF helicopters must be equipped with air-
                                      to-air missiles and flight data recorders. These capabilities are to be
                                      added as product improvements when they are developed.In addition,
                                      production costs for the MH-6OKcould increaseif production of the
                                      basic UH-60 Black Hawk ends as planned with the fiscal year 1991
                                      purchase. The Army has not yet estimated this potential cost increase.

Descriptionsof the Army’s SpecialOperations ’
Helicopter Modification Programs

                    The Army modification programs for the SOF helicopter systems are
                    among the most demanding helicopter development tasks to date. The
                    modification programs stress commonality of upgrades to mission equip-
                    ment systems.The MH-47E and the MH-6OKhelicopters also contain a
                    common state-of-the-art integrated avionics subsystem.


MH-4’7EHelicopter   The MH-47E is being produced through a modification to the Army’s
                    ongoing CH-47Dhelicopter modernization contract. Under the
                    CH-47Dmodernization effort, the Army is upgrading and modernizing
                    earlier models of its tandem-rotor, twin-engine, medium-lift CH-47 heli-
                    copter to provide improved handling and increasedperformance. The
                    Army had planned a total fleet of 472 CH-47Dmodel helicopters. How-
                    ever, that number will be reduced to 421 if all 51 planned
                    MH-47E models are produced.
                    The MH-47 “E” model will include somebut not all of the
                    CH-47Dmodel’s improvements. In addition to some“D” modifications,
                    the MH-47E model will include an internal cargo-handling system,
                    internal auxiliary fuel tanks, a terrain following/terrain avoidance
                    radar, a forward-looking infrared radar, a rotor brake, an air-to-air
                    refueling probe, a rescuehoist, additional troop seats,0.50-caliber
                    machine guns, and T&L-714 engines(seefig. 1.1).The MH-47E will also
                    contain avionics system upgrades and an integrated avionics subsystem.
                    Avionics improvements include aircraft survivability equipment, and
                    the integrated avionics system includes both monochromeand color dis-
                    play monitors, mission and display processors,a map display
