CONCEPT OF TOW MISSILE WEAPON EMPLOYMENT (U)

SECTION I

NARRATIVE SUMMARY

1. (C) Statement of Requirement:

a. The TOW Weapon System will fulfill the Heavy ~ntitank/ Assault Weapon System (HA/Aw) requirement. TOW is designed to deliver accurate, effective fire against targets at ranges from 65 to 3 0 0 0 meters. In its primary role, that of antitank, TOW will be used to destroy for- mations of armored vehicles before the firepower and shock action of the enemy armor can be brought to bear effectively. In the assault weapon role, TOW will be employed against vehicles of all kinds, fi4ld fortifi- cations, emplacements, pillboxes, and grouped personnel. It will be organic to infantry, mechanized infantry, airborne and air mobile battalions. It will also be used by selected Army aviation units in the helicopter role. Present plans call for its mounting on the Advanced Aerial Fire Support System when developed.


b. The HAIAW requirement is e s t ab l i shed i n subparagraph 237b (10) of t h e Combat Development Object ives Guide (CDOG). The HaIAW Q u a l i t a t i v e Mater ia l Requirement (QMR) is included i n Annex A. The ope ra t iona l requirements a r e shown i n Figure 1-1.

2. (C) Scope and Object ive: The o b j e c t i v e of the TOW p r o j e c t i s t o develop a weapon system t o provide a long range, h i g h - l e t h a l i t y a n t i t a n k l a s s a u l t c a p a b i l i t y f o r i n f a n t r y u n i t s .

a. Engineering approach:

(1) Develop a wire guided, command- to- l ine-of - s i g h t , i n f r a - r ed t racked, aerodynamically contro.lled, a n t i t a n k m i s s i l e system us ing a HE shaped charge warhead. The shaped charge warhead is designed t o d e f e a t the heav ie s t tanks expected t o appear on the b a t t l e f i e l d dur ing t h e period 1970 t o 1975. Basic design concept is t o use e x i s t - ing components w i th in the s t a t e of the a r t . Because of the an t i c ipa - t e d high dens i ty of TOW m i s s i l e s i n forward b a t t l e a r e a s , the m i s s i l e is being designed t o be handled a s a "round of ammunitiontt without checkout o r r e p a i r .

(2) The launcher w i l l include a l l mechanisms, guidance e l e c t r o n i c s , power supply, o p t i c s , and mounts requi red t o launch, t r ack , and command the m i s s i l e i n f l i g h t .

(3) The guided m i s s i l e is shipped i n and f i r e d from a conta iner which serves a s the r e a r por t ion of the launch tube.

(4) The key engineering design e f f o r t f o r the TOW Weapon System included:

(a) An e l e c t r o n i c a l l y modulated i n f r a r e d source f o r t he mis s i l e .

(b) A wire dispensing mechanism mounted i n the a f t end 2f t he mis s i l e .

( c ) Night f i r i n g capab i l i t y .

b. Descript ion of P r i n c i p l e s of Operation. The TOW Heavy Anti tank Weapon System c o n s i s t s o f guided m i s s i l e and launcher sub- systems. The m i s s i l e , launched from a t r a i n a b l e hollow tube, i s t racked i n f l i g h t by an in f r a red sensor boresighted with the tube and aimed a t the t a r g e t by the gunner using an o p t i c a l s i g h t . A coded i n f r a r e d s i g n a l is provided by a modulated xenon XR source c a r r i e d i n the r e a r of the mis s i l e . Mis s i l e p o s i t i o n e r r o r s , measured by the in f r a red sensor on the launcher , a r e t r a n s l a t e d t o c o r r e c t i v e s t e e r i n g commands and t ransmi t ted over a two-wire l i n k dispensed from the m i s s i l e , The m i s s i l e is au tomat ica l ly commanded t o f l y the l i n e of s i g h t e s t ab l i shed by the gunner. .

c. (C) Operational Concept (U)

(1) The TOW Weapon System w i l l accompany infant ry under a v a r i e t y of mobil i ty conditions. The TOW system w i l l be capable of being f i r e d from c a r r i e r vehic les and from the ground mount. Mounts w i l l provide the system mobil i ty equal t o t h a t of the o the r elements of ths using organization.

(2) TOW'S primary r o l e w i l l be t o destroy enemy armor before i ts firepower can be brought t o bear e f fec t ive ly . In the secondary assau l t ro le , the system w i l l be employed agains t hard point t a r g e t s and personnel adjacent t o material ta rgets .

d. (U) Material Replaced. TOW w i l l replace the 106MM r e c o i l l e s s r i f l e and ENTAC ant i tank guided missile i n in fan t ry u n i t s and the SS-11 ant i tank guided miss i le a s he l icopter armament. Benefits of the TOW System over the systems t o be replaced include a 65 meter minimum range opposed t o a 400-500 meter minimum range f o r SS-11 and ENTAC; removal of a la rge degree of the opportunity f o r gunner e r r o r s ince the TOW guidance system i s automatic i n operat ion andsigni f icant system weight reduction and increased maximum range over the r e c o i 1 l . e ~ ~ r i f l e . TOW thus provides on one system a range coverage now requir- ing three systems and improves the h i t and k i l l p robab i l i ty fo r the e n t i r e range bY a fac to r of two.

g. Required Miss ion D u r a t . :

(1) Required miss ion d u r a t i o n must be such a s t o a l low engagement of 3 moving t a r g e t s a t va ry ing ranges i n a 90' a r c from t h e weapon p o s i t i o n w i t h i n 1-112 minutes ( e s s e n t i a l ) ; 1 minute ( d e s i r e d ) .

Twenty-five a d d i t i o n a l seconds are r e q u i r e d under f a v o r a b l e c o n d i t i o n s f o r t a r g e t a c q u i s i t i o n and r e l o a d i n g . T h i s a d d i t i o n a l t ime may be up t o 55 seconds under


adverse conditions. Although the launcher electronics is not operating during the acquisition and reloading period, no launcher maintenance or checkout can be allowed during this time for satisfactory achievement of the 3-target mission. Therefore, the required mission duration must be considered as 85 seconds.

h. Planned Utilization Rate:

(1) Wartime; The launcher will be energized for firings and self-tests. Pressing the fire button turns on the launcher electre nics and fires the missile. The launcher turns off automatically upon completion of flight and opening of case clamp. Maximum launcher electronics operating time will not exceed 18 seconds for any missile flight. Self-tests will normally occur once per day or whenever the mount is dis- placed to a new firing position. Self-tests require 27 seconds running time. Current planned combat consumption rate is 1.08 missiles per launcher per day for the European theater. For all other areas, the rate is .73.

(2) Peacetime: Normal training utilization will be to fire 4 rounds per launcher per year on the average. During training, the launcher will be energized~~pproximately 10.5 hours per week on the- average. The launcher is energized for simulated missile flights and self-test training. Tracking practice, which represents the bulk of training activity, does not require turn-on of the launcher unless the training set is also being used.

2. (C) Planning Information Affecting Reliability and Maintainability

a. Mean Downtime: Organizational maintenance mean downtime should not exceed 30 minutes essential, 15 minutes desired. Monthly organizational downtime should be 2 hours or less. Field maintenance downtime shall be less than 6 hours.

(1) Corrective Maintenance:

a. A maintainability demonstration on the TOW launcher was held in May 1966. Subsequent demonstrations have been held on other TOW equipment except the training set. A trade-off was made to substitute a maintenance evaluation for maintainability demonstration. The training set maintenance evaluation has been accomplished. For the demonstrations system parts were identified and the quantity used was noted. Items were grouped together into categories having similar functions (parts, modules, subassemblies). The product of the item failure rate 1000 hours obtained from reliability data and the quantity of each item was used as a base in determining the percentage contribution to the total failure rate for each category. The tasks to be performed at both the operatorlcrew (o/C) and direct/general support (DS/GS) maintenance levels were selected from each category based on the contribution of each category to the total failure rate.


(b) Due to the non-availability of Land Combat Support System (LCSS) equipment, detection, fault isolation, and test could not be accomplished directly for the DS/GS level tasks. The LCSS equipment is automated test equipment under development for the support of several missile systems; i.e, TOW, SHILLELAGH, LANCE. Corrective maintenance times for the accomplishment of the DS/GS tasks with LCSS were estimated.

(c) The results of the demonstration verified that the maintainability requirements can be met, No quantitative deficiencies were revealed during the evaluation. The demonstrated mean corrective maintenance times were well within the quantitative requirements. The qualitative maintainability characteristics observed during the demonstration were generally in conformance with the design objectives; however, there were some instances in which design change recommendations were made.

(2) Schedule Maintenance:

Mean downtime on system for scheduled maintenance shall be:

Five minutes -daily inspection

(Note: Can be accomplished without deadlining

launcher)

1-1/2 hours - quarterly system check b. Reliability After Storage:

(1) There must be no degradation of the 95% required reliability after limited storage and performing organizational maintenance or after extended storage and field maintenance.

(2) The missile is to be treated as a round of amnunition. After delivery from the factory, no tests will be performed and no repairs will be made on the missile in the field. The missile contains many one-shot items which cannot be dynamicellv tested. The missile will be adequately protected from shock and humidity through the use of missile overpacks.

(c) Minimum Allowable Time Between Scheduled Maintenance of the system.

REGRADED UNCLASS l F l I

Maintenance Echelon Minimum Time Allowable Organizational 24 hours Direct Support 90 days General Support 90 days Depot as necessary

d. Test and Checkout Methods:

(1) Missiles - The missiLe is handled as a round of anmunition. There is no test or checkout of missile in the field after leaving manufacture, TOW missiles determined to be unservice- able by surveillance inspections or by the user will be returned to the Anniston Army Depot. Maintenance and rebuild procedures and equipment are being developed to give the depot a capability for complete overhaul and rebuild of the missile. The only maintenance activity envisioned in the field for the missile is surveillance and replacement desiccant.

(2) Launcher - TOW launcher will be supnorted by test and checkout in all the normal maintenance categories.. Capabilities for test and checkout are:

(a) Organizational - The launcher electronics unit includes a built-in, self test capability. Indicator dials signify a go-no-go condition for each of the launcher components; i.e., missile guidance set, optical sight, traversing unit, and battery. The self- test features includes a check of the internal boresight. Adjustment knobs are provided for operator use in alignment of system optics.

(b) Direct and General Support - Special automatic type test equipment, the Land Combat Support System, will be used to support the TOW system along with other designated systems. The LCSS will fault isolate down to card and piece part.' The LCSS supporting unit will be attached to the Division Maintenance Battalion. Forward of the LCSS site, TOW will be supported by a contact team on an as- called basis. This support will normally be limited to exchange of aesemb1ies.or subassemblies.

(c) Depot Support - TOW w i l l be supported at depot level using the basic LCSS test equipment augmented with additional factory-type-test equipment to give a complete TOW equipment support capability.

(3) Ancillary Equipment

(a) Battery Charger - The battery charger will be located in the TOE 9-5501, Det EO, TOW missile maintenance support section. The batteries will be charged in the maintenance shelters of DET EO. Organizational maintenance will be limited to minor maintenance such as indicator lamp replacements. DS and GS

3. (U) Plans for a Reliability Program Outlining How Reliability will be Achieved- An effective and economically controlled reliability program was established and placed in operation early in the TOW Weapon system R&D Program. The reliability program has been and will be continuously maintained. The reliability program consists of, but is not limited to, the following elements and/or activities:

a. Determination or Prediction of Material Operational and Test Environmental Conditions

(1) (U) Determination of Equipment Environmental Conditions - The equipment environmental stress conditions have been determined. These environmental stress conditions include: (1) those introduced by the TOW Weapon System Design; (2) the storage, handling and shipping environments; (3) the launch and in-flight environments; and (4) the natural environments. Environmental stress conditions have been determined by means of laboratory tests, flight tests, and firing tests (static firings or firings into a "catcher"). Sufficient measurements have been made to determine the average value and vari- ability of these environmental stress conditions, as well as their characteristics. See HAC Report No. TOW-T3, Rev. B, Oct 1966 TOW Environmental Criteria, and HAC Report No. TOW-T3, Addendum A, Training Set XM-70 Sep 1967, TOW Environmental Criteria.

(2) (U) Reliability Allocation (Apportionment) - Reli- ability mathematical models have been developed based on system analysis and utilizing the procedure described in MIL-STD-756A and parts failure rates found in MIL-HDBK-217 to apportion reliability to the system elements, including module level. Reliability apportionment shall be updated, as the results of product assurance verification testing are obtained to permit trade-offs to be made. The apportioned values will be the criteria against which safety margins will be established and demonstrated reliability values compared. See HAC Report No. TOW-T2, Rev, E, March 1967, TOW Reliability Program Plan.

(3) (U) Reliability Estimate (Predictions1 -A mathematical model representing the inherent reliability of all functional items including module level was developed based on the proposed design. The model is used to generate reliability prediction values, and, as design changes are made, revised prediction values are generated. See figure 111-2 for apportioned, predicted, and achieved reliability values.

b. Statement of System Reliability Requirements

See Section LIL, paragraph 1.d.

REGRADED UNCLASS l F l ED I b

c. Reliability Test and Demonstration Program and Plans

(1) (U) Reliability Test and Demonstration Program- The Reliability Test and Demonstration Program, which was established for evaluating system reliability throughout the Design and Development Phase, is complete,. This program was accomplished by an integrated test program conducted concurrently with a reliability assessment program. The integrated test program was designed to evaluate all aspects of the performance capability of the system and its components. A Production Reliability Test and Demonstration Program are to be conducted during tteproduction phase.

(a) Reliability Test and Demonstration Plans - Reliability Test and Demonstration Plans have been prepared describ- ing testing from which data can be obtained for valid reliability measurement and assessment. These tests include qualification tests, flight tests, environmental over-stress tests, tests-to-failure, and reliability tests. (See TOW Launcher Reliability Demonstration Test Plan TOW-T12 and TOW Launcher Reliability Test Report, TOW-T21). A Reliability Demonstration Tests for the Training Set XM-70 was completed, but is unsatisfactory. (See TOW XM-70 Training Set Contractor Test Plan and TOW-T85, XM-70 Training Set Reliability Demonstration Test Plan and TOW-TI20 XM-70 Training Set reliability demonstration test report).

d, Test Plans and Schedules

(1) (U) A production test program plan has been generated. Reliability confidence test plans have been generated by the contract- or for a production program of periodic reliability testing of production missile components. The above tests plans are significant parts of the overall production phase product assurance verification test program which is presently in the planning stage. Engineering tests will be conducted in desert, tropical, and arctic regions.

(2) (U) Qualification Tests - All qualification test plans have been prepared and all qualification testing is complete except for source lamps for which qualification testing is in process. In- house qualification testing of the flight motor with new insulation (RPD) has been completed,

(3) (U) Reliabi1ity.Tests - Reliability tests have been or shall be conducted as follows:

(a) Reliability tests on early configuration launchers have been accomplished, and a laboratory reliability test involving 200 simulated firings using a later configuration launcher has been completed. The launcher system shall be further tested under simulated tactical operating, troop training, operating and storage and handling environments. Sufficient life cycle testing shall be conducted to demonstrate the reliability requirement at an 80"A confidence level.


(b) Flight Tests - The Engineering Test/Service Test Flight Program is in process. System reliability is computed on a 50 round moving average based on a ratio of successful flights to attempted flights. A scoring coamittee made up of representatives from WSMR, Ft. Benning, Ga., Quality and Reliability Management Off ice (MICOM) , Hughes Aircraft Co, , and the TOW Project Office has been established. ConJerences are held periodically for the purpose of evaluating the flights as success, failure or no-test based on scoring criteria agreed to by the scoring counnittee.

e. Test Obiectives

(1) (U) The objectives of the ET/ST are to measure the field reliability of the system and to determine what redesign, if any, may be required.

(2) (U) The objective of the reliability/qualification testing program is to assure that all major components have been successfully tested prior to their use in production. All major R69 components testing except for source lamps has beer performed by the contractor.

(3) (U) The objective of the Product Assurance Verification test program is to determine whether or not the j system reliability achieved in R&D is not degraded during production.

f. Goals to be Demonstrated - The present TOW Weapon System reliability goal is to demonstrate that the system meets the QMR.

g. Reliability Activities for Evaluation, Analysis and Product Improvement

(1) (U) Development Reliability Assessment - Periodic assessment of achieved reliability versus required reliability will continue to be conducted throughout the production phase, Feedback of data will provide a basis for determining what reliability im- provements, if sny, need to be made to meet the required reliability,

(2) (U) List of Qualified Items - A list of qualified items has been prepared comprised of items of known reliability under - - given environments, and that are qualified for use in the TOW weapon System. Items shall not be placed on the list unless they have under- gone testing or adequate usage to demonstrate their reliability. An initial list of qualified items was established early in the design phase and has been continually updated as additional items were qualified by test. Present contracts requires updated qualified parts list on monthly basis.

(3) (U) Design Analysis - Design analysis is complete except for SAIE and items that may be redesigned.

UNCLASSIFIED


(4) (U) Effects of Handling and Storage on Product Assurance - A determination shall be made of the environmental and stress parameters to which the missile system and launcher subsystem will be exposed during transportation, handling, and storage, and the product shall be designed to withstand or be protected against them. The contractor, under the direction of the Project Manager (supported by the Research and Engineering Directorate), will determine the effects of handling and storage on Product Assurance. Launcher air drop tests and container drop tests both with and without overpack are complete. Missile drop tests and transportation testing aboard the M-113 Armor- ed Personnel Carrier are complete. As a result'of these tests, shock absorbers are being designed into the missile racks aboard the M-113.

h. Plan for Specification Reviews

Reliability and maintainability personnel have reviewed and signed off on specification development during the design process. This procedure will be continued throughout all redesign effort. Specifications are reviewed for the adequacy of design requirements including performance, reliability, maintainability, environmental requirements, and test requirements. TOW Weapon System In-Process Reviews were held during May 1966 and April 1967. No In-Process Review was held in FY 68 and none are scheduled for FY 69; however, an LPR is tentatively scheduled for the first quarter FY 70.

i. Plan for Reliability Design Reviews

(1) (U) Design Reviews - Formal design reviews at unit, system, and weapon system level of th- TOW system have been conducted and will continue to be conducted, for SAIE and redesigned items. Reviews will be conducted on units, systems, and weapon system prog- ressively at the conclusion of product assurance verification testing and thereafter whenever a major design change is proposed. These reviews have been and will continue to be performed consisting of representatives from design, reliability, quality control, aaintain- ability, and others as appropriate. Informal reviews are participated in by reliability engineers and designers on a continual basis. Reviews will be made on units r - d systems as soon as all units and the Weapon System have completed product assurance verification testing. A similar procedure will be followed for vehicle adaption kits, trainer, battery charger and night sight. These reviews will encompass a technical review of each design and interfaces and includes such considerations as:

(a) Design Analysis - Including worst case analysis of circuits, results of failure mode and effects analysis, standardi- zation and application of parts and materials, stress analysis, maintainability, producibility, human factors, safety, trade-offs, etc.

j. Special Procedures for Malfunction and Failure Reportinq and Analysis During R&D .

(1) (U) Failure Mode, Effect and Criticality Analysis- Detailed analyses of the weapon system down to part level have been made identifying potential failure modes of the system and the expected consequences of a failure in a specific mode. Failure mode analyses were begun as soon as design was begun and shall be updated as design changes occur,.

(2) (U) Failure Analysis - All pertinent information as it becomes available, is being analyzed and evaluated and histories maintained as appropriate on all levels of products. Where significant or recurring detrimental information occurs, a formal "Failure Analysis" is being conducted. This failure analysis shall yield: the mode of failure, the cause of failure, and the classification of the failure as to cause, Results of this analysis will be directed to the proper functional group for action. Included as part of the failure analysis documentation shall be the identification of similar or related parts which may contain the same inherent weakness or which would benefit by a similar improvement.

4. (U) Reliability Data File

a. Reliability Data Analysis and Feedback - Information and data reflecting the reliability of the equipment has been and will be continually collected, analyzed, and evaluated expeditiously so that it may continue to be available to design groups. This shall be accomplished by the utilization of a uniform and compatible reporting and feedback system designed to collect and disseminate part, equipment, and system reliability data. Such data has been and will be continually collected from design acceptance laboratory, field and flight tests, and will be maintained as applicable in a reliability data file.

. A reliability data file in accordance with paragraph 8, A l l 705-50, has been established and shall be maintained.

5. (C) Reliability Matrix - A matrix of reliability factors is shown on page LII-17, The achieved reliabilities of the missile launcher and-warhead section are listed under "CURRENT STATUS" on page 111-17. The achieved reliability values for the missile and launcher were obtained from flight test results. The achieved reliability values for the warhead section (armament) were obtained from Picatinny Arsenal Laboratory tests.

6. (U) Maintainability Plans. A significant portion of the maintainability effort has been accomplished on TOW equipment to date. However, maintainability effort will be continued throughout the life cycle of the equipment to assure effective and efficient maintenance operations on the e,quipment. All indications to date tend to show that the maintenance requirements.of the TOW QMR have been well surpassed. The following items summarize accomplishments to date and specific actions scheduled for the future:

a. Quantification of Maintainability

Quantification guidance for maintainability was contained in the TOW QMR. This guidance was expanded in Technical Requirement 398 which was made a part of TOW contracts. Mathematical models for the TOW launcher, battery charger, and vehicle kits were prepared and maintainability predictions and apportionments were accomplished. Maintainability demonstration plans were established and demonstrations were performed. These demonstrations show that the quantitative requirements had been met.

b. Operational and Test Environmental Conditions

Operational environmental characteristics were specified in the TOW QMR to be the same as AR 705-15, Change 3. These were made a part of TR 398 and included in the TOW contracts. The contractor has performed tests under the extremes of the environmental conditions set forth and design changes were made where environmental requirements had not been met. The TOW engineeringlservice test program is scheduled to perform tests under all the environmental conditions specified. Test details for the engineering/service tests are contained in Engineering/ Service Test Plan for Heavy Antitank/Assault Weapon, TOW dated Oct 66. Test details for other environmental tests are contained in Hughes Aircraft Company (HAC) reliability test plans numbered in the series RTP 1 through RTP 136. (See Para. 3.d. (1)

c. System Maintainability Requirements and Goals

The maintainability goal for TOW equipment must be such as to allow an achievement of the maintenance requirements of the TOW QMR as a minimum. It is significant to note that maintainability is next to last in the priority of characteristics in the TOW QMR. In spite of this fact, statistical data and maintenance operations to date indicate that all of the maintenance requirements of the QMR have been significantly surpassed as indicated in TOW maintainability design data reports, report numbers TOW-T13, -T18, -T23 and addendums thereto. The quantitative and qualitative maintainability goals for TOW are enumerated in the TOW Maintainability Program Report, Number TOW-T6.

REGRADED UNCLASSIF IED - JOD,DPC UNbL-fJ II 1 I- 0

d. Test Spec if icat ions

The maintainability program for TOW was prepared under MIL-M-45765 (MI), dated 1 Apr 63. This document was made a part of TOW contracts. A maintainability program plan was prepared by the contractor and is contained in TOW Maintainability Plan, Report TOW-T6. Maintainability design data reports were prepared using the guidelines of MIL-M-45765. The data for MDDR's 1 and 2, as called for in MIL-M- 45765, were incorporated into a singe1 document called Report Number 1 and 2 due to the short time schedule at the time of preparation. Main- tainability statistical data and maintainability demonstration plans are contained in MDDR Number 3. The results of the maintainability demonstrations are contained in MDDR Number 4.

e. General Test Plans and Schedules

Maintainability demonstrations have been completed on all TOW equipment except the TOW training set. Maintenance evalilation on the TOW training set was accomplished 2d Qtr, CY 68, in lieu of maintainability demonstration due to the added benefits to be received from the maintenance evaluation in this time period. TOW equipment is to be supported by the Land Combat Support Systernj(LCSS). Maintenance functions against TOW equipment using LCSS will be accomplished in the LCSS engineeringlservice test program. LCSS equipment has not been available for use in the TOW engineeringlservice test program and all maintenance has been performed by the contractor. It is anticipated that TOW items will be in test during CY 70 as the TQW-LCSS program tapes become available through the LCSS contractor. In general, one complete TOW system will be utilized in the test with back-up equipment being utilized as necessary and available. The engineeringlservice tests are being performed under the cognizance of TECOM.

f. Objectives of Tests

(1) Test Objectives are:

(a) Determination of the extent to which maintainability requirements have been met in the equipment.

(b) Determination of ability to maintain TOW equipment utilizing the test facilities, personnel, documentation, and repair parts authorized for the purpose.

(2) The configuration of equipment to be tested will be the same as production configuration except for required changes between the time of manufacture or modification of equipment being tested and production.

REGRADED UNCLASSIFIED - JOD,DPC -. r - Z - g. Maintenance Task and Skill Analysis

A task and skill analysis was prepared on the TOW launcher by the New Equipment Training Division, S M Directorate, MICOM. The task and skill analysi8 is dated 15 Aug 66. Due to the similarity of maintenance tasks on other TOW equipment to those on the TOW launcher, other task and skill analyses are not planned.

h. Maintainability Apportionment

(1) Maintainability apportionment and predictions have been accomplished for all equipment except the training set. These apportionments and predictions are contained in the Maintainability Design Data Reports 1 through 3. Test plans for verifying the apportionment and predictions are contained in Maintainability Design Data Report Number 3. Maintainability demonstrations were performed by the contractor with MICOM and CONARC representatives in attendance at the tests. Results of these tests are contained in MDDR # 4.

(2) The MDDR's have been updated to include maintainability apportionment and prediction on the TOW Training Set.

i. Procedures fqr Maintenance

(1) Maintenance evaluations on all TOW items have been per formed. The TOW launcher maintenance evaluation was performed at Redstone Arsenal. The TOW vehicle adapter maintenance evaluation was performed at the White Sands Missile Range. The maintenance evaluation on the TOW battery charger was started at WSMR but was terminated due to operational and maintenance difficulties encountered in the battery charger. A second maintenance evaluation was started at Redstone Arsenal after redesign to correct the outstanding deficiencies discovered in the firs t maintenance evaluation. This maintenance evaluation was not completed due to design change requirements dicta- ted by improper operations of the battery charger broupht about by temnetati lre changes. This condition has now been corrected. and the battery charger has been released for engineering service test.

(2) Maintenance evaluation on the TOW training set was accomplished the 2nd Qtr, CY 1968.

(3) All deficiencies found during the maintenance evaluations are recorded, and a maintenance evaluation report is prepared. These reports are forwarded to the contractor for his evaluation and recommendation. The reports along with the contractor evaluation and recommendation are then processed for proper corrective act ions.

j . In-Process Reviews

Maintainability aspects of TOW equipment are considered as a part of each in-process review on TOW equipment.

k. Maintainability Design Reviews

(1) Continuous liaison has been maintained between the TOW contractor and MICOM areas of maintainability. The following actions are indicative of review points to assure achievement of optimum system maintainability:

(a) Contractor's technical reports are reviewed for maintainability significant items.

(b) The contractor's maintenance data reports are screened for maintenance or maintainability significant trends or problems.

(c) Results of reviews of TON English Language Program (ELP) (test and fault isolation programs for the programming of LCSS) are screened for maintenance and maintainability problems.

(d) Maintainability design data reports are reviewed as they are completed.

(e) Maintainability demonstrations are performed in which equipment maintenance operations are accomplished. Action is taken to assure that these tasks are representative of all required maintenance tasks on TON equipment.

(2) The contractor's plan for maintainability design review is contained in TOW Maintainability Design Review and Evaluation Report Number TOW - T9.

1, Procedures for Failure Reporting

(1) Specific procedures for the use and submittal of failure reports are contained i~r the TOW Contractor Maintenance and Engineering Support Plan Report Number TOW-T34. The following forms are utilized in trouble and failure reporting:

(a) Trouble and failure Xeport (contractor's report). (b) DA Form 2407 (used for reporting all mainten-

ance act ions).

(c) Equipment Performance Report (TECOM report)


( 2 ) A s a safeguard, a s p e c i a l procedure has been adopted t o a s su re p o s i t i v e a c t i o n on a l l r epo r t s received from the engineering1 s e r v i c e t e s t program.

The tests being conducted by the above agencies will determine limits of performance reliability data and demonstrate the ability of the TOW Weapon System to perform the mission of which it was designed. The summary phase schedule of these tests are shown in FIG. B-1.

2. Laboratory Tests - HAC Product Assurance Evaluation and subsystem tests are being per-

formed on parts, components and systems during the contractor's prototype research and development program. The evaluation and subsystem tests are detail performance tests conducted to support the development of the final design and to determine the compliance of the design with its interface and design specifications. Qualification tests, as part of the product assurance program, are tests performed before, during, or after exposure of the hardware to selected environmental stresses such as shock, vibration and temperature. Qualification tests demonstrate the adequacy of the hardware built to the design drawings and specifications. Reliability tests, another part of the product assurance program are conducted to determine reliability boundaries. Prototype hardware built to design drawings and specifications and accepted by the contractor's acceptance test program will be subjected to selected environments.

3. Fie ld Tests - HAC
