CHAPTER 1INTRODUCTION

1.1 PURPOSE AND SCOPEThe primary purpose of this manual is to provide assembly, disassembly, and testing procedures for MineMk 65 Mods 0, 1 and 3 to all personnel having responsibility for preparation of the mine for deployment.1.2 ITEM IDENTIFICATIONItem names used in this manual conform to the DOD standardized names used in FEDLOG andTW010-AA-ORD-010 Authorized Configuration Data for Mines. Major weapon components andspecial-purpose test equipment, to which mark-mod designators have been assigned, are identified bytheir item name and mark-mod designators. Component parts, hazardous materials, and special tools areidentified by drawing or part numbers. These numbers, when referred to FEDLOG, cross-reference tonational stock numbers, DOD logistics codes, piece parts information, and to all printed data pertinent tosupply, maintenance, and use of the item.1.3 JOB SHEETSDetailed assembly and disassembly procedures are provided in the form of removable job sheets. Inaddition to specified instructions and illustrations, each job sheet lists the assembly level items, piece parts,and support items (tools and bulk items) needed to perform the job. Numbers in parentheses in these listsgive item quantities if more than one item is needed per mine. Whenever possible, the same job sheet isused to provide procedures for both mine mods; however, when different procedures are required, they aresupplied in separate job sheets.Assembly job sheets are provided in chapter 4 and disassembly job sheets are contained in chapter 5.Job sheets are numbered consecutively in each section to allow orderly return to the proper section ofthe manual after use. For the performance of specific assembly or disassembly operations, refer to thetable of contents; then remove only the job sheet(s) that are specified for a specific job. Each job sheet iscomplete in itself, i.e., containing all the instructions, illustrations, quality assurance check points, and listof components, tools, and support items necessary to perform specific tasks. Except for Table 4-10A (jobsheet 4-8), which references particular assembly and disassembly procedures in various job sheets, thereis no need to refer elsewhere or to flip back and forth in the manual for supplementary procedures, tables,guidelines, etc. Setting up can easily be tailored to the needs of any mine operation. When only a fewmines are to be assembled in a shop, entire groups of job sheets can be performed by one or two assemblypersonnel. For a larger operation, an assembly line can be set-up and appropriate job sheets assigned tothe various workstations. Job sheets can be removed from the manual and taken to that location.Some assembly/disassembly procedures in this manual can be performed simultaneously. It is permissibleto perform those operations simultaneously even though they may follow one another in numerical order.However, for safety reasons, mine assembly personnel are not authorized to arbitrarily change the order ofnonsimultaneous operations without local command approval.1.4 ILLUSTRATED PARTS BREAKDOWN (IPB)The IPB is in appendix D of this manual.1.5 QUALITY ASSURANCEInspection requirements are included within the assembly procedures as operational steps located atrecommended points of inspection. Changes to the sequence and location of inspections are allowedprovided all inspections are performed and no safety requirements are violated. Quality Assurance (QA)inspections shall be recorded in accordance with local activity plan in support of NAVSEAINST 8020.14(series). Inspectors need not be specifically designated inspectors, they may be line supervisors or anyqualified personnel as determined by the Commanding Officer or Officer in Charge (CO/OIC).

CHAPTER 3SHOP PROCEDURES

3.1 PURPOSESpecific shop procedures to be followed when performing assembly, disassembly, and maintenance onMine Mk 65 Mods 0, 1 and 3 are presented in this chapter. These procedures supplement standard shoppractices contained in SW550-AA-MMI-010 and OP 5 (for shore based operations) and OP 4 (for afloatoperations), and are designed to enhance personnel and shop safety.3.2 MINE HANDLINGIntermediate Maintenance Activity (IMA) personnel perform mine assembly, disassembly, andmaintenance in accordance with the procedures presented in this manual. These functions can beaccomplished individually or on a production line basis. The method by which the task will beaccomplished depends on the quantity of mines/components to be processed, the number of personnelassigned, and the time available to meet the delivery order.Safety is most important when performing mine assembly, disassembly, or maintenance operations.Although separate locations are safest and most desirable, assembly line operation may be specified toaccomplish larger tasks at the discretion of the Commanding Officer. Proper handling of the mines willensure safety is maintained.Assembled mines that have not been planted are first taken to an explosive handling area for removal ofthe S&A Mk 45 Subassembly. This can be done by Mineman personnel, provided the mines have not beendamaged. Assembled mines that evidence damage must be rendered safe only by Explosive OrdnanceDisposal (EOD) personnel following approved EOD procedures. After the mines have been renderedsafe, they can be moved to an area designated as safe from Hazardous Effect of Radiation on Ordnance(HERO) for disassembly. To facilitate mine handling as performed by mine assembly units, various itemsof handling equipment for mines are available. All are described in SW023-AB-WHS-010.3.3 WATERTIGHT OPENINGSTorque, lubrication to be applied at mine openings, and preformed packing installation instructions toensure watertight integrity are specified in the applicable job sheets. Torque will be applied in accordancewith the procedures contained in SW550-AA-MMI-010. Torque values listed in the job sheets are thefinal torque values. Used preformed packings must never be installed when assembling mines. At thetime of installation, all new preformed packings are required to have a light coat of grease applied asspecified. Prior to installation, all preformed packings are inspected for cuts, abrasions, and other damageor deformities. If any irregularity is found, the preformed packing must be cut and discarded.3.4 TESTING REQUIREMENTSClass-B criteria for use during programmed maintenance are contained in SW550-AA-MMI-010. Thesesame criteria are to be used, if required, during assembly.Instructions for Class-C testing are contained in the job sheets in this manual and are predicated on the useof Class-C special purpose test sets and equipment. Table 3-1 lists the tests and functions performed withthese test sets.Class-C tests are vital to safety and operational predictability and are mandatory at specified steps of allmine assembly operations.

3.5 PAINTING, STENCILING, AND COLOR CODINGIn addition to the thermal coating or paint applied for safety or preservation purposes, weapons and theircomponents may require stenciling for identification data and color coding to identify explosive contentsin accordance with international agreements. Instructions in the job sheets in this manual are restricted tothe need to alter such stenciled information to ensure it reflects changes made in the course of assemblyor disassembly. Instructions for periodic restoration of the thermal coating or paint at an IMA, as may berequired for continued safety or preservation, are found in SW550-AA-MMI-010.3.6 PACKAGINGMost mine components are packaged in reusable metal shipping and storage drums or ammunition boxes.

3.6.1 Unpackaging. When unpackaging, containers and packaging material must be retained torepackage mine components should mines be disassembled. Mine components should be unpackaged asspecified in the appropriate job sheet. General guidance for unpackaging mine components is as follows:

a. Containers and ammunition boxes must be carefully opened, taking care not to damage anycomponents. As items are removed from containers, packaging material must be replaced incontainers.

b. Containers and packaging material must be secured and placed in a designated storage area.

3.6.2 Repackaging. Repackaging, as detailed in job sheets, consists of replacing items in the propercontainers with proper packaging material and securing the containers.3.7 MINE MK 65 MODS 0, 1, AND 3 ASSEMBLY CONFIGURATIONSAssembly Configurations A, Modified A, C, and F are authorized and are defined as follows:

3.7.1 Assembly Configuration A. Mine completely assembled, operationally tested, and ready forimmediate delivery to the planting agent. Mine can be equipped with either an activated Battery Mk 131or Mk 132.

3.7.2 Assembly Configuration Modified A. Differs from a Configuration A mine. The Battery Mk131 is used and is unactivated. The mine receives a modified systems test at the time of mine assembly,but is not programmed. When the mine is to be upgraded to Configuration A, the access cover of the mine

SW551-A3-MMI-010

case is removed, the battery activated with a screwdriver, preset programming is accomplished with theTest Set Mk 595, Mk 597, or Programmer Mk 11 and the access cover reinstalled.

3.7.3 Assembly Configuration C. Assembly configuration C is only authorized for Mines Mk 65 Mod0. Mine Mk 65 Mods 1 and 3 are not authorized to be stored in configuration C. Configuration C containsan unactivated Battery Mk 131, an unprogrammed actuation system assembled in the Mine Mk 65. TheSafety Device, Arming Group Mk 45 and Arming Device Mk 2 are maintained in storage separate from themine case. When the mine is to be upgraded, the access cover is removed, the Battery Mk 131 is activated,the TDD is programmed and a systems test is performed. Then the access cover is replaced and the S&AMk 45 Subassembly with the Arming Device Mk 2 is installed.

3.7.4 Assembly Configuration F. Consists of an explosive-loaded Mine Case Mk 65 Mod 0 as shippedin the Shipping and Storage Skid Mk 25 with nose fairing, tail section, suspension lugs, battery spacer, andCable Assembly CA 1218 installed. (All other mine components are in storage.)3.8 EXPLOSIVE HANDLING PRACTICESThe handling, assembling, testing, and disassembling of mines and their components require constantattention to the prevention of damage and injuries, which can be expected if explosive items are misusedor mishandled. The following paragraphs discuss some standard practices designed to prevent suchaccidents. Additional safety practices for explosive handling are found in OP 4 (Ammunition Afloat), OP5 (Ammunition Ashore), and SW550-AA-MMI-010.3.9 ARMING CYCLE OF MINE MK 65The arming cycle of Mine Mk 65 is initiated by withdrawal of the S&A Mk 45 Subassembly lanyard fromthe thermal battery firing pin and the hydrostatic piston housings when the mine is released from the aircraft(Figure 3-1). Lanyard withdrawal releases the firing pin, which activates Thermal Battery Mk 134. Batteryactivation initiates flight gear deployment and the mine battery/TDD sterilizer function in the Mod 0 andMod 1. Activation of the TDD Mk 71 is initiated by closure of a switch in the S&A. Although released,the hydrostatic piston will remain in place until hydrostatic pressure required for completion of the armingcycle is met.

3.11 ELECTROMAGNETIC RADIATIONElectromagnetic radiation (EMR) is radio frequency energy from such sources as radars andcommunications transmitters. The radio frequency spectrum used by the Navy extends from Very LowFrequency (VLF) to Extra High Frequency (EHF). Transmission power of the EMR may approach10 kilowatts for communications equipment, while peak power outputs for radars extend to about 5megawatts. Electro-Explosive Devices (EEDs) are vulnerable to this EMR; therefore, assembly anddisassembly of Mines, Mk 65 Mods 0, 1 and 3 are restricted to areas which are declared safe fromHazards of Electromagnetic Radiation to Ordnance (HERO). Such areas are designated as HERO-safeenvironments. EMR may enter a mine as a wave radiated through any opening. The most susceptibleperiods are during assembly and disassembly in electromagnetic fields. Detailed restrictions and thenecessary general and theoretical analysis to enable the reader to make intelligent assessments of thehazards present may be found in Radio Frequency Hazards to Ordnance, Personnel and Fuel, TechnicalManual, NAVSEA OP 3565/NAVAIR 16-1-529. In addition, the safety regulations provided in OP 4(Ammunition Afloat) and OP 5 (Ammunition Ashore) must be followed.3.12 ELECTROSTATIC DISCHARGE (ESD)The Target Detecting Device (TDD) Mk 57, Mk 58, Mk 71, and TDD Adapter Mk 123 contain elementswhich are sensitive to Electrostatic Discharge (ESD). An ESD Control Program is required to protectthese components during unpackaging/repackaging, assembly/disassembly, and system testing actions.Where such protection is required, CAUTIONs, specifying protective actions, are inserted precedingthe appropriate steps of the job sheet. Actions specified are designed to meet the requirements ofDOD-STD-1686, Electrostatic Discharge Program; and DOD-HDBK-263, Electrostatic DischargeControl Handbook, and are consistent with guidelines contained in NAVSEA SE003-AA-TRN-010,Electrostatic Discharge Training Manual.3.13 ESD WORKSTATIONUse of the ESD Workstation is specified during performance of certain steps of the job sheets. ESDmaterials are listed in Table 3-2. An ESD workstation is prepared as follows:
