Another upgrade to the Group II was the Hawkeye 2000, which featured the same APS-145 radar but incorporated an upgraded mission computer and CIC (Combat Information Center) workstations (Advanced Control Indicator Set or ACIS and carries the U.S. Navy's new CEC (cooperative engagement capability) data-link system. It is also fitted with a larger capacity vapor cycle avionics cooling system. Starting in 2007 a hardware and software upgrade package began to be added to existing Hawkeye 2000 aircraft. This upgrade allows faster processing, double current trackfile capacity and access to satellite information networks. Hawkeye 2000 cockpits being upgraded include solid-state glass displays and a GPS-approach capability. The remaining Hawkeye Group II NAV Upgrade aircraft received GPS approach capability, but did not get the solid-state glass displays.
