This is a critical requirement identified in the 2023 Weapons and Tactics Conference (WEPTAC) Modernization Book. The ANG C-130J fleet requires self-defense capabilities to detect and defeat factor modern threats ts specifically designed to target large Mobility Air Forces aircraft. To detect these threats, C-130Js require an open mission system-compliant digital backbone executing processing at the forward edge and connecting the platform to Air Battle Management System and Joint All Domain Command and Control architectures. To defeat these threats, C-130Js require onboard and/or off-board threat jamming, decoys, and kinetic and non-kinetic defense measures. Some options to achieve the aforementioned effects are; Block 30 or Block 35 AN/AAQ-24 Large Aircraft IR Countermeasures (LAIRCM) system, to improve detection against advanced man-portable air defense systems threats, while degrading the enemy's ability to engage. C-130Js require an Infrared Suppression System capable of reducing the aircraft's heat signature from engine exhaust in all aspects. C-130J aircraft require a digital radar warning require an Infrared Suppression System (IRSS) capable of reducing the aircraft's heat signature from engine exhaust in all aspects.
