since been taken up. The first two Wedgetails were assembled, modified and tested in Seattle, Washington, while the remainder were modified by Boeing Australia, with deliveries once set to begin in 2006,. Boeing and Northrop teamed with Boeing Australia, and BAE Systems Australia. Boeing Australia provides training, maintenance and support, BAE provides EWSP systems, Electronic Support Measures (ESM) systems and ground support systems. On 29 June 2006, the Australian Minister for Defence, Brendan Nelson, stated that the Wedgetail was delayed despite Boeing's prior assurance that work was on schedule. Boeing announced an 18-month delay due to problems integrating radar and sensor systems, and did not expected delivery until early 2009. Additionally, Boeing incurred $770 million in charges over the delay in 2006. On 20 June 2008, Boeing announced a further delay due to integration issues with the radar and Electronic Support Measure (ESM) systems. On 26 November 2009, Boeing delivered the first two 737 AEW&Cs to the Royal Australian Air Force (RAAF). These aircraft remained Boeing owned and operated prior to the RAAF's formal acceptance on 5 May 2010. The RAAF accepted its sixth and last 737 AEW&C on 5 June 2012. All RAAF Wedgetails are operated by No. 2 Squadron RAAF and based at RAAF Base Williamtown with a permanent detachment at RAAF Base Tindal. In November 2012, the Wedgetail achieved Initial Operational Capability. On 1 April 2014, the first operational sortie occurred in the search for Malaysia Airlines Flight 370, helping control maritime patrol aircraft off Western Australia's coast. On 1 October 2014, a Wedgetail conducted the first Australian sortie over Iraq supporting coalition forces conducting airstrikes against the Islamic State of Iraq and the Levant (ISIL). On 26 May 2015, the Wedgetail fleet achieved final operational capability (FOC). In November 2015, the Wedgetail performed the longest Australian command and control mission in a war zone during a 17-hour, 6-minute combat mission, requiring two air-to-air refuelings to stay aloft. Australian Wedgetail crews routinely perform 13-hour missions. In early April 2016, Rotation 5 of aircrew and maintenance personnel that had been operating the RAAF Wedgetail in the Middle East achieved a record 100 percent mission success rate in Coalition operations against ISIS. The E-7A successfully conducted all 36 missions, each lasting upwards of 12 hours, amounting to nearly 500 hours of flying for the one aircraft.
