The Navy-led sea-based JPALS (Increment 1A) will replace the obsolete SPN-46 and SPN-35 radar systems only once all Navy aircraft have been equipped with JPALS (Inc. 1B) aircraft systems. JPALS Inc. 1A is an Major Defense Acquisition Program Aircraft Category (ACAT) 1D program, which includes the development, integration, installation, and testing of the sea-based system and is currently the only active increment for the JPALS program. Specific FY13 accomplishments will include delivery of all eight planned Engineering Development Model (EDM)s, delivery of three Avionics Test Kits, and completion of initial flight test of JPALS. These are critical steps towards the JPALS, Increment 1A ship system, reaching Initial Operational Capability (IOC) in 2014. More..
