Well this is what I have found on the net
"F-16 COMMON CONFIGURATION IMPLEMENTATION PROGRAM (CCIP)
650 USAF Block 40/42 F-16s are being upgraded under the Common Configuration Implementation Program (CCIP). The first phase of the program (first aircraft completed in January 2002) provides core computer and colour cockpit modifications. The second, which began in September 2002, involves fitting the advanced AN/APX-113 interrogator/transponder and Lockheed Martin Sniper XR advanced FLIR targeting pod. The third, which started in July 2003, adds Link 16 datalink, the Boeing Joint Helmet-Mounted Cueing System and an electronic horizontal situation indicator."
