the Block 40 variant were also announced. The Air Force's fiscal year 2013 budget request said it had resolved to divest itself of the Block 30 variant; however, the National Defense Authorization Act for Fiscal Year 2013 mandated operations of the Block 30 fleet through the end of 2014. The USAF plans to procure 45 RQ-4B Global Hawks as of 2013. Before retiring in 2014, ACC commander, General Mike Hostage said of the U-2's replacement by the drone that "The combatant commanders are going to suffer for eight years and the best they’re going to get is 90 percent". During 2010–2013, costs of flying the RQ-4 fell by more than 50%. In 2010, the cost per flight hour was $40,600, with contractor logistic support making up $25,000 per flight hour of this figure. By mid-2013, cost per flight hour dropped to $18,900, contractor logistic support having dropped to $11,000 per flight hour. This was in part due to higher usage, spreading logistics and support costs over a higher number of flight hours. In July 2022, the US Air Force announced that it plans to retire the Global Hawk in 2027. EuroHawk The German Air Force (Luftwaffe) ordered a variant of the RQ-4B, to be equipped with a customized sensor suite, designated "EuroHawk". The aircraft was based on the RQ-4B Block 20/30/40 and was to be equipped with an EADS-built signals intelligence (SIGINT) package; it was intended to fulfill Germany's requirement to replace their aging Dassault-Breguet Atlantique electronic surveillance aircraft of the Marineflieger (German Naval Air Arm). The EADS sensor package is composed of six wing-mounted pods; reportedly these sensor pods could potentially be used on other platforms, including crewed aircraft. The EuroHawk was officially rolled out on 8 October 2009 and its first flight took place on 29 June 2010. It underwent several months of flight testing at Edwards Air Force Base. On 21 July 2011, the first EuroHawk arrived in Manching, Germany; after which it was scheduled to receive its SIGINT sensor package and undergo further testing and pilot training until the first quarter of 2012. The Luftwaffe planned to station the type with Taktisches Luftwaffengeschwader 51 ("Reconnaissance wing 51"). In 2011 the German Ministry of Defence was aware of difficulties with the certification for use within the European airspace. During flight trials, problems with the EuroHawk's flight control system were found; the German certification process was also complicated
