DCS: F/A-18C Hornet is one of the most, if not THE most detailed and realistic implementation of a F18 simulation for the consumer market. In the words of Eagle Dynamics:

Our Hornet is the culmination of more than 40 man years of intense research, technology development, art creation, and ground-breaking coding. The Hornet brings the first, true, multi-role fighter to the skies of DCS World with equally impressive air-to-surface and air-to-air capabilities.
