were ordered by the Turkish Air Force, with an option for two more. Turkish Aerospace Industries (TAI) is the Peace Eagle's primary subcontractor, performing parts production, testing, aircraft assembly and conversion. Another Turkish subcontractor, HAVELSAN, is responsible for ground support elements, system analysis and software support. HAVELSAN is also the only foreign company licensed by the U.S. Government to receive critical source codes. Peace Eagle 1 was modified and tested by Boeing in the US, while Peace Eagle 2, 3 and 4 were modified and tested at TAI's facilities in Ankara, Turkey, in partnership with Boeing and several Turkish companies. In 2006, the four Peace Eagles were scheduled to be delivered in 2008. In September 2007, Boeing completed the first Peace Eagle test flight. On 4 June 2008, it was announced that Peace Eagle 2, the second 737 AEW&C, had completed modifications; flight and mission system checks were completed in the third quarter of 2008. In 2013, Israel delivered EW equipment for the Peace Eagle under US pressure. On 21 February 2014, the first Peace Eagle, named Kuzey (meaning North), was formally accepted by the Turkish Air Force. The remaining three aircraft are named Güney (South), Doğu (East) and Batı (West). The fourth and final Peace Eagle was delivered in December 2015.

Boeing beat the other entrant, IAI Elta's Gulfstream G550-based aircraft, which was eliminated from the competition in August 2006. The first Peace Eye aircraft was delivered to Gimhae Air Base, Busan for acceptance testing on 1 August 2011 with the remaining three aircraft delivered every six months until 2012. The second aircraft was modified into an AEW&C configuration by Korea Aerospace Industries (KAI), then delivered to Gimhae Air Base on 13 December 2011. After receiving AEW&C modifications by KAI, the third aircraft was delivered on 17 May 2012 to Gimhae Air Base. The fourth aircraft was delivered on 24 October 2012. United Kingdom In October 2018, the British Government announced that it was in talks with Boeing and the Royal Australian Air Force about the potential for the E-7 Wedgetail to replace its E-3D fleet.
