The official record also shows a 48.5% availability for France's Dassault Rafale fighter fleet in 2015 (93 aircraft in service with the air force) with a budgeted maintenance cost of EUR343.90 million (USD 364.56 million). The Mirage 2000D is suffering from extensive use in operations 'Chammal' (against the Islamic State) and 'Barkhane' (Sahel area), with a low availability rate of 32.90%.
Although older (23 years on average against 18 years for the 2000D), France's remaining Mirage 2000C and 2000B (15 and 7 aircraft) show a correct 45.6% availability. The total cost of maintenance for the Mirage 2000 fleet (150 aircraft of different versions in total) amounted to EUR309.80 million in 2015.
O sea 2,1 millones de dólares anuales por cada M2000 sólo en partes, rotables y repuestos. Aún así con una disponibilidad que no llega al 50%.
