AN / ALQ-214

from Wikipedia, the free encyclopedia

The AN / ALQ-214 ( JETDS designation) is an airborne system for electronic countermeasures at medium to short distances. It is produced by the US group ITT and the British company BAE Systems .

description

The ALQ-214, also called "Integrated Defensive Electronic Countermeasures" (IDECM), was designed to interfere with radar-controlled guided weapons of all kinds, including weapons with passive radar control and " home-on-jam " technology. It is intended for self-protection and is built into the airframe of the carrier platform. Initially the system was equipped with three AN / ALE-50 trolling lures , with the AN / ALE-55 bait being used since 2006 . This is ejected in the event of an attack and dragged on a fiberglass rope at some distance behind the aircraft. The bait can either act as a transmitter for the electrical countermeasures and thus render rockets harmless with "home-on-jam" technology (e.g. AIM-120 AMRAAM or Wympel R-77 ), or as a radar bait, which with the help of a special Radar system actively radar-guided weapons a larger and more attractive target than the carrier aircraft. The ALQ-214 can also send jamming signals via transmitters on the carrier aircraft, while the ALE-55 also works in jamming or decoy mode. Furthermore, the system with the AN / ALE-47 - decoys -Werfer connected to enemy missiles to confuse targeted with additional radar and Infrarottäuschkörpern. All software is written in C ++ .

The system has been in service since 2003 and is priced at approximately $ 1.7 million each. At least 57 units have now been shipped and production is still ongoing.
