Directed Infrared Counter Measures
Directed Infrared Counter Measures ( DIRCM , also: Directional Infrared Counter Measures ; German for example: Guided or Directed Infrared Countermeasures ) is the name for protective systems that are intended to enable military and civil aircraft to repel approaching guided missiles equipped with IR seeker heads. Aircraft are at risk from portable one-man surface-to-air missiles (e.g. stingers ), particularly during take-off and landing . DIRCM is counted among the distance-active protective measures .
Procedure
DIRCM uses an active method to disrupt the infrared seeker heads of approaching missiles. High-energy pulses directed at the seeker head in close succession are intended to disrupt or even destroy the missile guidance system. The system can be used to protect both military and civilian large fixed-wing transport aircraft (e.g. Air Force One ) right through to small helicopters.
construction
The system basically consists of the components
- Missile warning,
- IR passive tracker ,
- Laser fine tracker and
- Destructive laser.
The destructive laser blinds or destroys the IR detector of the approaching missile with high-energy pulses. The target acquisition and destruction process takes place in a very short time and at a safe distance from the aircraft to be protected.
Systems
Four systems are currently known:
DIRCM
A project by Diehl BGT Defense in cooperation with EADS is carried out under this generic name . The demonstrator program was successfully completed in 2006. The development of the operational system will begin in 2009, and the first DIRCM systems will be installed in the A400M transporter from 2014 .
AN / AAQ-24
The system, also known as NEMESIS, was developed by Northrop Grumman and is already in use with the USAF and the British armed forces. It is planned to equip all 59 AC-130 Gunships and MC-130 Combat Talon aircraft of the Air Force Special Operations Command ( AFSOC ) with DIRCM systems. The Royal Air Force plans to install 131 systems in fixed and rotary wing aircraft.
AN / AAQ-24 is also the basis for the Northrop-Grumman-Guardian-System used in civil aviation since 2007 .
L-370-5 "President-S"
The Russian DIRCM system will u. a. used in Mil Mi-26 military transport helicopters since 2011 . The Kamow Ka-52 is also equipped with it.
ELT / 572
The Italian DIRCM system is in the procurement phase by the Italian Air Force. The manufacturer is Elettronica SpA in Rome (Italy).
