The IDECM System is a Radio Frequency (RF), self-protection electronic countermeasure suite on the F/A-18 aircraft. IDECM improves the survivability of the F/A-18 aircraft against RF guided threats during Air-to-Ground/Surface and Air-to-Air missions. The system is comprised of onboard components, which receive and process radar signals, along with onboard and offboard jammer components that transmit appropriate RF jamming responses. There are four IDECM variants in development, production, or sustainment. Blocks 1-3 are compatible with F/A-18E/F aircraft only. Block 4 is compatible with F/A-18C-F aircraft. IDECM Block-2 (IB-2) ALQ-214(V)3: ALQ-214(V)3 deliveries are 100% complete and all systems were delivered at least one month ahead of the contracted schedule. Harris (formerly Exelis) delivered 276 ALQ-214(V)3 production systems under the LRIP 1 through FRP 8 contracts.
