PURCHASE DESCRIPTION

HIGH MOBILITY MULTIPURPOSE WHEELED VECHICLE

(HMMWV)

This specification is approved for use by the U.S. Army Tank-automotive and Armaments Command and is available for use by all Departments and Agencies of the Department of Defense.

1. SCOPE

1.1 Scope. This system specification identifies the physical, performance and inspection requirements for the A2 series and Expanded Capacity Vehicle (ECV) series of the High Mobility Multi-Purpose Wheeled Vehicles (HMMWV). Unless otherwise noted in this specification, the M1123 variant shall be included as part of the A2 series of vehicles. Also the M1151/M1152/M1165/M1167 shall be included as part of the ECV series of vehicles. In simple terms, the M1151 has the body of the M1025A2 and placed onto the chassis of the ECV; the M1152 has the body of the M1097A2 (2-man version) placed onto the chassis of the ECV; the M1165 has the body of the M1097A2 (4-man version) placed onto the chassis of the ECV; and the M1167 is the TOW/ITAS variant based off of the M1151. (See Addendum in rear.) The system specification establishes these requirements by identifying the following:

a. Technical data requirements from which the vehicle is to be produced.

b. Physical characteristics and performance requirements for the vehicles produced.

c. Identification of the performance and quality test requirements used to verify the vehicles meet the specified performance standards.

The technical data package provided as part of this system specification identifies specifications and installations at a component level. The TDP does not identify the performance requirements of the final assemblage of these components at the system level. The physical characteristics and performance requirements are identified by this specification. Therefore, this specification shall form the basis for establishing and evaluating the vehicle's physical characteristics and performance.

1.2 General Description. The A2 vehicles represent the third stage of HMMWV evolution. The ECV vehicles represent the fourth stage of HMMWV evolution. Like the basic HMMWV and A1 series, the A2 and ECV vehicles are comprised of many common components. The various models are defined by different body configurations designed to meet

ATPD 2099E

particular mission roles. These roles include transport of materials, weapon systems, equipment, and personnel. While operating in these roles the vehicles are operated on primary and secondary roads, trails and off road terrain. The vehicles are also capable of fording water and operation in temperatures ranging from Basic Cold to Basic Hot conditions. With application of kits, the vehicles are also capable of arctic operation and deep water fording. Some major changes for the A2 and ECV vehicles include:

1. 6.5 Liter Engine (Turbo for ECV)

2. 4L80 Electronic Transmission

3. New Radiator

4. New Exhaust w/Catalytic Converter

5. Central Tire Inflation System Ready

6. Improved Air Cleaner

7. Dual Voltage Electrical System

8. Improved Collapsible Steering Column

9. Relocated Driver's Mirror
