1.2 Background
The ANG has selected the AN/APX-113-56 Combined Interrogator/Transponder (CIT) AIFF system for their fleet of Block 25/30/32 C-model F-16 aircraft. To date, 81 ANG aircraft have been modified with the -56 AIFF system. Current funding will allow for fielding of approximately 100 additional systems, with expected future funding for additional installations within the next three years.

AIFF is a critical system for the ANG ASA mission of national security, reducing fratricide and pilot workload while increasing pilot situational awareness. The ANG AIFF program has been funded with a combination of Defense Emergency Response Funds (DERF), Global War on Terror (GWOT) and Congressional Plus-up sources of funding.
AIFF was initially fielded with Software Capabilities Update (SCU) 6 in November 2007. Group A and B Hardware kits are fully qualified and have been flying on ANG F-16 aircraft.

This acquisition has been approved as a sole source award to BAE Systems (Cage Code: 80249).
