M-93 Fox NBC Reconnaissance Vehicle

The M93 Fox Nuclear-Biological-Chemical Reconnaissance Vehicle is a fully integrated NBC reconnaissance system with a dedicated system of NBC detection, warning, and sampling equipment integrated into a six-wheeled, all-wheel-drive armored vehicle. The M93 Fox is used by the U.S. Army and Marine Corps.

The M93 Fox was originally developed in Germany (as the Fuchs) for use by the German military. The U.S. requirement for the Fox system was generated in the late 1980s in response to a perceived need to quickly field a chemical reconnaissance vehicle to U.S. forces in Europe.

M93 Fox Nuclear-Biological-Chemical (NBC) Reconnaissance Vehicle

The M93 Fox NBC Reconnaissance System (NBCRS) Non-Developmental Item Program consisted of three acquisition phases:

  • The Interim System Production phase provided 48 urgently-needed German-produced vehicles (designated the XM93) that met many of the U.S. requirements. As part of this phase, the German Government donated an additional 60 "Americanized" XM93 vehicles to the U.S. in support of Operation Desert Storm.
  • The System Improvement Phase provided vehicles (designated the XM93E1) for testing to ensure they satisfied all U.S. Requirements of Operational Capability.
  • The ongoing Block 1 modification phase involves upgrading all XM93 vehicles to the M93A1 configuration.

The Requirement Document for the Block 1 Modification Type Classification is dated February 1991. In June 1995 it was approved for production and fielding. Production qualification was completed between January and July 1998 and the first U.S. unit was equipped with the NBCRS-Fox Block 1 system (M93A1) in October 1998.

The M93A1 contains an enhanced NBC sensor suite consisting of the M21 Remote Sensing Chemical Agent Alarm (RSCAAL), MM1 Mobile Mass Spectrometer, Chemical Agent Monitor/Improved Chemical Agent Monitor (CAM/ICAM), AN/VDR-2 Beta Radiac, and M22 Automatic Chemical Agent Detector/Alarm (ACADA). The NBC sensor suite has been digitally linked with the communications and navigation subsystems by a dual-purpose central processor system known as the Multipurpose Integrated Chemical Agent Detector (MICAD). The MICAD processor fully automates NBC warning and reporting functions and provides the crew commander with full situational awareness of the Fox’s NBC sensors, navigation, and communications systems.

The M93A1 Fox is also equipped with an advanced position navigation system (Global Positioning System [GPS] and the Autonomous Navigation System [ANAV]) that enables the system to accurately locate and report agent contamination. It has an over-pressure filtration system that permits the crew to operate in a shirt-sleeve environment that is fully protected from the effects of NBC agents and contamination outside the vehicle. The automated features of the M93A1 reduce the crew requirements to three soldiers from the four soldiers required to operate the M93 Fox.

The M93A1 is capable of detecting chemical contamination in its immediate environment through point detection and at a distance through the use of the M21 RSCAAL. The Fox system automatically integrates contamination information from sensors with input from on-board navigation and meteorological systems and rapidly transmits via SINCGARS radios its digital NBC warning messages to warn follow-on forces. Two Reconnaissance systems, working as a team, will normally precede the movement of troops and materiel to locate and mark contaminated areas.

M93 Fox is manufactured by General Dynamics Land Systems (Detroit, MI and Anniston, AL) and by Henschel Wehrtechnik (Kassel, Germany).
