air support air-to-ground, photo reconnaissance, forward air controller-airborne, and tactical air controller-airborne. Over Libya, four Spanish Hornets participated in enforcing a no-fly zone. Switzerland The Swiss Air Force purchased 26 C models and eight D models. Aircraft were delivered from January 1996 to December 1999. Three D models and one C model had been lost in crashes as of 2016. On 14 October 2015, an F/A-18D crashed in France during training with two Swiss Air Force Northrop F-5s in the Swiss/French training area EURAC25; the pilot ejected safely. In late 2007, Switzerland requested to be included in the F/A-18C/D Upgrade 25 Program, to extend the useful life of its F/A-18C/Ds. The program includes significant upgrades to the avionics and mission computer, 12 ATFLIR surveillance and targeting pods, and 44 sets of AN/ALR-67v3 ECM equipment. In October 2008, the Swiss Hornet fleet reached the 50,000 flight hour milestone. The Swiss Air Force has also taken delivery of two F/A-18C full-scale mock-ups for use as ground crew interactive training simulators. Locally built by Hugo Wolf AG, they are externally accurate copies and have been registered as Boeing F/A-18C (Hugo Wolf) aircraft with tail numbers X-5098 and X-5099. These include a complex equipment fit, including many original cockpit components and instruments, allowing the simulation of fires, fuel leaks, nosewheel collapse and other emergency scenarios. X-5098 is permanently stationed at Payerne Air Base while X-5099, the first one built, is moved between air bases according to training demands. Air USA Air USA, a provider of training services to various U.S. government agencies, has signed a deal to acquire Australia's remaining F/A-18A/B Hornets, after 25 of these were sold to Canada. Air USA is slated to receive 46 Hornets, with 36 in flyable condition and is planning to restore the remaining 10 to airworthiness as well. The Hornets will be used as testers and aggressor jets to train pilots. Potential operators The F/A-18C and F/A-18D were considered by the French Navy (Marine Nationale) during the 1980s for deployment on their aircraft carriers Clemenceau and Foch and again in the 1990s for the later nuclear-powered Charles de Gaulle, in the event that the Dassault Rafale M was not brought into service when originally planned. Austria, Chile, Czech Republic, Hungary, Philippines, Poland, Singapore and Turkey evaluated the Hornet but did not purchase it. Thailand ordered four C and four D model Hornets but the Asian financial crisis
