Section Il. EQUIPMENT DESCRIPTION
EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND FEATURES
Purpose
The M992 is afield artillery ammunition support vehicle comparable to current field artillery
weapons (M109A2 and M110A2 self-propelled howitzer class) in terms of speed, mobility,
and survivability.
Capabilities
This full-tracked, self-propelled, diesel-powered vehicle is highly mobile and
maneuverable. It is capable of long-range, high-speed operation on improved roads. It is
also well-suited to rough terrain, muddy or marshy ground, sand, snow, and ice. The M992
can also ford waterways where maximum depth is 42 inches.
Features
Ammunition handling equipment (AHE), including a hydraulically-operated conveyor
and X-Y stacker, the projectile rack assemblies, and related components.
A diesel-powered auxiliary power unit (APU) used to drive the hydraulic system and
recharge vehicle batteries.
Simplified test equipment for internal combustion engine (STE/lCE).
Automatic Fire Extinguishing System (AFES).
AFES is an automatic and manual electric system that when actuated provides
fire extinguishing capability for the engine and crew compartment. It consists of
test/alarm panels, sensors and associated equipment explained later on in this
section and the Chapter 4 operating instructions.
Automatic electric operation will automatically sense and discharge an agent to
extinguish hydrocarbon fires. The crew system provides an automatic electric
second shot capability should the fire continue burning or a second fire occurs.
Manual electric operation must be manually activated by the crew to discharge the
agent to extinguish fires. The crew system second shot manual electric activation
is available if the fire continues to burn. It must be manually activated by a crew
member.
These systems will not activate unless the crew/engine test and alarm panel
maintenance switches are in the horizontal power on-normal operational position.
(See Chapter 4).
Nuclear, biological, and chemical (NBC) agent detection and protection system.
Ammunition storage racks and compartments.
