In June 2006, Pakistan completed the purchase of six Saab 2000 turboprop aircraft to be equipped with the Saab-Ericsson ERIEYE Airborne Early Warning system. Revised in May 2007 due to renegotiation with the Government of Pakistan, only five aircraft will be delivered, four of which will be equipped with the Erieye system. On 3 April 2008, the first Saab 2000 Erieye AEW&amp;C was rolled out and presented to Pakistan Air Force officials during a ceremony in Sweden.
