Introduction
The AN/APX-113(V) combined interrogator/transponder (CIT) is a development of the AN/APX-111 in service on Kuwaiti F/A-18 Hornets. It was developed for the F-16 Fighting Falcon and is presently used for the Block 15 A/B MLU, Block 20 A/B, Block 30/32, Block 40, Block 50/52 C/D, and Block 60 aircraft. The system’s versatility is demonstrated by other applications, which include ASW and surveillance helicopters, aerostats, MiG-29 Fulcrum updates, Japan’s F-2 fighter, and other international platforms. The AN/APX-113(V) CIT includes mode S Elementary and Enhanced Surveillance (ELS and EHS) capability and has an AIMS-approved mode 5 growth path.
Description
The AN/APX-113 is supported by the BAE Systems KIV-78 crypto computer. The KIV-78 crypto computer was developed for simultaneous encryption and decryption for interrogator and transponder elements for mode 4 and/or mode 5. The APX-113CIT gives an aircraft, in addition to the onboard radar, the ability to autonomously detect and identify airborne targets at extended range. The APX-113 is credited with a maximum effective range of 100nm, presumably in the active (interrogation) mode.
