Flight trials in France to open its flight envelope and evaluate its stealth characteristics were successfully completed in March 2015. These tests were followed by sensor evaluation trials in Italy, which were completed on August 25, 2015. The last leg of flight trials take place in Sweden and will include live fire trials. In July 2016 extensive stealth and detection tests were conducted with the nEUROn and the Charles de Gaulle carrier group. The nEUROn was to penetrate the aircraft carrier defensive area to test its stealth and the capacity of the carrier group to detect it. Funding The contract is valued at €405 million, and allows industry to begin a three-year system definition and design phase with related low-observability studies. This phase will be followed by the development and assembly phase, and by a first flight in 2011. It is planned that the 2-year flight-test program (2010–2012) will entail about 100 sorties, including the launch of a laser-guided bomb tentatively scheduled for 2012. The initial €400 million budget was increased by €5 million in 2006 due to the addition of a modular bomb bay including a designator and a laser-guided bomb. In February 2006, DGA had announced that France will provide €202.5 million, half of the program's €405 million ($480 million) budget, while the remaining funds will be supplied by the other participating member nations. In December 2005, the Swedish defence ministry reported the national share would be €75 million, of which €66 million would be financed by Saab AB. The cost of Spain's participation to the program is estimated at €35.5 million, spread over the 2007–2012 period. Derived production UCAV unit cost is estimated by Dassault to be €25 million. Potential French-British follow-on In November 2014, a two-year feasibility study was announced by the French and British
