NATO FORACS is a NATO project open to all the Alliance initiated by a Memorandum of Understanding signed in 1974. The FORACS Ranges measure the bearing, range, position, and heading accuracy of sensors in surface ships, submarines, and maritime aircraft to satisfy national requirements and to meet NATO material readiness standards, through dynamic combat system performance evaluation, thereby providing an essential contribution to naval combat readiness.

Its mission is to measure the bearing, range, heading and positional errors of sensors on-board surface ships, submarines and helicopters. These calibration measurements establish confidence among the member naval forces that target locations can be accurately passed from sensors to weapon systems and other NATO combatant units.

Sensors tested include:
  • Active, Passive, Dipping and Towed Array Sonars
  • Mine Hunting Systems
  • Fire Control and Search Radars
  • ESM and RDF equipment
  • Infrared, Laser and TV Sensors
  • Optical Sights and Peloruses
  • Periscopes
  • Inertial Navigation Systems and Gyrocompasses
  • Global Positioning Systems (GPS)

Calibration measurements are of interest to:
  • Ship's personnel for alignment
  • Operational Commands for a measure of combat readiness
  • Material Commands for evaluation of maintenance and overall design performance
