Downloaded from https://www.everyspec.com MIL-HDBK-633A FOREWORD 1. This handbook is approved for use by the Department and Agencies of the Department of Defense. 2. This Military Handbook provides information on standard mobile electric power sources for use by all Departments and Agencies of the Department of Defense (DoD). 3.

Preparation of this document has been authorized by the Department of Defense Directive 4120.11, Standardization of Mobile Electric Power (MEP) Generating Sources, April 13, 2004, which assigns to the Project Manager, Mobile Electric Power the responsibility for establishing the Department of Defense (DoD) Standard Family of Mobile Electric Power Generating Sources (MEPGS).

This MEP handbook revises the Standard Family by the deletion of Military Standard gasoline engine-driven generator sets, the addition of the 2 kW Military Tactical Generator (MTG), the MEP-501A (DC) and the MEP-531A (AC), and the replacement of the 3 kW - 60 kW Standard Family of Diesel Engine Driven (DED) models by Tactical Quiet Generators (TQG). These present and proposed MEPGS and their associated trailer mounted configurations are included in APPENDIX A The Auxiliary Power Units (APU) MEP-952A and MEP-903A, which have been added to the Standard Family in accordance with guidance provided in SARD-ZCS Memorandum, are in APPENDIX B . The power distribution systems are in APPENDIX C .

The following are extracts from DoD Directive 4120.11: (Additional information on this policy can be found at: http://www.dtic.mil/whs/directives/corres/pdf/412011p.pdf ). “4. POLICY 4.1. It is DoD policy to: 4.1.1. Establish, maintain, and provide a DoD standard family of MEP generating Sources for maximum DoD Component use. 4.1.2. Implement the standardization policies of DoD Instruction 5000.2 (reference (b)) on MEP generating sources through the establishment of common military operational requirements, design and development, procurement, logistic support, and operational use by: 4.1.2.1. Planning and coordinating the DoD development, engineering, and product improvement efforts.

The requirements will be satisfied to the maximum practicable extent through the use of nondevelopmental items, in accordance with Part 6, Section L of reference (b). 4.1.2.2. Ensuring the availability of standard MEP generating sources that will meet DoD- wide needs with the required electrical performance, reliability, maintainability, durability, and versatility by the most cost-effective means. 4.1.2.3. Reducing diversification of MEP generating sources entering the DoD supply system, thus minimizing logistic support without compromising mission accomplishment of the DoD Components. 4.1.2.4.

Standardizing, to the maximum extent practicable, the electrical output characteristics of the MEP generating sources, consistent with military systems and equipment needs under MIL-HDBK-633 (reference (c)).” 4. Fuel Standardization Policy DoD Directive 4140.25, Subject: DoD Management Policy for Energy Commodities and Related Services establishes DoD bulk Petroleum Management Policy. The fuel standardization policy, paragraph 4.2 of the DOD Directive 4140.25, follows: “4.2. Fuel Standardization. The Combatant Commanders shall develop plans to minimize the types of fuels required in joint operations. The Military Services shall design and ii

The Military Services will also qualify new systems to use readily available commercial-type fuels. Standard fuels approved by the Defense Standardization Program are listed in the Department of Defense Specifications and Standards under Federal Supply Group 91 listed in the ASSIST database. Primary fuel support for land-based air and ground forces in all theaters (overseas and in the Continental United States) shall be accomplished using a single kerosene-based fuel, in order of precedence:

JP-8, commercial jet fuel (with additive package), or commercial jet fuel (without additives), as approved by the Combatant Commander. Fuel support for ground forces may also be accomplished using commercially available diesel fuel when supplying jet fuel is not practicable or cost effective. Primary fuel support for sea-based aircraft shall be a high-flash kerosene-based fuel, designated JP-5. In overseas theaters where the predominant fuel requirement is in support of the Navy, JP-5 may be substituted for JP-8, as approved by the Combatant Commander. Conventionally powered ships shall use a distillate-type fuel, designated F- 76 for propulsion.

Military Sealift ships may use commercial marine fuels for propulsion. The type of fuel designated for the battlefield shall be specified by the Combatant Commander depending on fuel availability and equipment to be used within the theater. To the maximum extent practical, no new combat support or combat service support equipment or vehicles requiring gasoline-type fuels shall be acquired or developed unless the support concept is to supply fuel as a packaged product.” 5.
