The LIDACS (INSERT ACRONYM HERE) Counter-measures suite is a multimode system of passive electronic counter-measures used on aircraft.

Counter-Infrared

Flares

• 2F20: A universal pack of medium-sized high-heat magnesium-based flares.
  
  • 2F25: A universal pack of medium-sized, high-heat magnesium-based flares with parachutes attached for slower descent
    
• 3F30: A cocktail of both medium-sized and large-sized
  

Alkyl Aluminum-based pyrophoric flare

• 9F15: The current first-pick for low-flying attack aircraft and CAS missions, the 9F15 includes a "cocktail" of both high-heat MTV-based flares,(with and without parachutes), AA-based pyrophoric flares, and PP/HO spectrally balanced flares (with and without parachutes). The 9F15 can also semi-vertically (up to 65^o) eject flares rearward.
  
  • 9F15ER:: A 9F15 module modified for delayed ejection where the flares are ejected at a slower pace rather than all at once to increase time in the air & distance traveled while shrouded by flares.

9F30: A similar pack to the 9F15 but adapted for higher-altitude missions. Includes a "cocktail" of both high-heat MTV-based flares,(with and without parachutes), AA-based pyrophoric flares, and a mix of both instant-ignition and delayed ignition PP/HO spectrally balanced flares (with and without parachutes). Because the AA-based pyrophoric flares require additional oxygen, they are physically larger and thus are in less quantity than the 9F15 despite constituting an equal proportion of the dispenser.

• • 9F30ER: Delayed ejection modification of 9F30.

LIDACS-II

Due to the improved state of built-in RWR antennae found in the AC-88E Taipan, the LIDACS-II offers both improved ATD2 and better near-360^o coverage of the aircraft. Threat detection is improved to relative radar bandwith (i.e. low-frequency vs high-frequency vs VHF/UHF), which helps discriminate between likely sources of active radar missiles versus passive radar missiles. IRST/DAS nodes allow the system to "counter-predict" the trajectory of an oncoming missile, which in turn activate the IR Dazzlers "as needed", depending on whether or not the missile is proportional-pursuit or tail-chase.

LIDACS-III

The LIDACS-III is currently the most advanced system in the counter-measures suite.

A major feature of the LIDACS-III is its ability to sync and share data with the Sevât-M Counter-Emissions System. By offloading radar frequency discrimination to a separate computing system, it allows LIDACS-III to continue diverting processing power towards providing full spectrum awareness. The information provided by the Sevât-M is then back-loaded into threat identification by the LIDACS system, and then either the pilot is alerted or proper counter-measures are deployed. Furthermore, identification of an approximate "emissions profile" can be used to better employ DRFM Jamming.

LIDACS-IIIv2

A proposed improvement module to deal with off-boresight air-to-air missiles. (???)

Controversy

Incorporation Estavez-Kilo (IEK) was the target of a misinformation lawsuit by Navayelle Systems after claiming that the Amérifighter EF-20 acted as a "miniature ELINT" aircraft to foreign potential buyers. Navayelle, who designed the LIDACS & Sevat-M systems, clarified that the abilities of the EF-20 are purely defensive in nature and not for intelligence gathering. IEK and Navayelle likely settled out-of-court, but what is publicly known is that all branding of the EF-20 (AC/A-20 in Inyurstan service) as a "miniature ELINT" was dropped.
