1 BACKGROUND

1.1 Scope

This specification identifies the physical and performance requirements for a FM200 based Automatic Fire Extinguishing System (AFES) for the P-19R. This AFES shall be capable of extinguishing accidental and combat initiated fires. The FM200-based system is intended to extinguish fires within the crew cab.

The P-19R is Aircraft Rescue Fire Fighting (ARFF) is intended to replace the A/S32 P-19A Aircraft Crash and Structure Fire Fighting Truck, TAMCN D1064, known as the P-19A. The primary mission of the P- 19R is fighting aircraft fires and crew rescue. The secondary mission of the vehicle is to fight other types of fires, such as brush and structural fires. It may also be used as a non-lethal means of crowd and riot control.

The P-19R will have functional capabilities to minimize the consequences of fire and emergency incidents including: fire suppression and extinguishment on aircraft and structures, casualty extrication and rescue.

Capabilities include the ability to seat a four person crew meeting USMC mobility and transportability requirements at base and stations, and forward operation bases. It is equipped with fire suppression compounds and extinguishing agents, handheld extinguishers, and specialized rescue tools to extinguish aircraft fires, protect rescue personnel, cool explosive ordnance, extract aircrews, and successfully accomplish each rescue mission.

The P-19R ARFF vehicle will meet both the 2012 National Fire Protection Association (NFPA) - 414 standards and the expeditionary fire fighting and aircraft rescue requirements of the United States Marine Corps (USMC). This program will replace P-19A’s at both Operational Force (OPFOR) units and garrison mobile equipment (GME) at USMC Air Facilities.

1.2 General Description

Current operational environments necessitate a vehicle mounted FM 200 based (HFC 227ea plus 5-10% sodium bicarbonate powder) system AFES be incorporated into the P-19R. This system shall provide protection for the crew compartment and shall be capable of detecting and suppressing hydrocarbon fuel fires and explosions initiated by various threats using an automatic system. This system should minimize weight impact and space claim whenever possible.

1.3 Vehicle Variants

The Crew Compartment AFES shall be developed for the P-19R. All testing shall be conducted with the windows rolled up.
