The TOPGUN course has changed over time. In the 1970s, it was four weeks long; in the 1980s, five weeks. The final F-4 Phantoms went through the class in March 1985, and the final F-14 Tomcats in October 2003. Programs formerly run by TOPGUN that have been transferred to other commands or discontinued include Fleet Air Superiority Training (FAST) and Hornet Fleet Air Superiority Training (HFAST): coordinated programs of academics and simulators, training fighter pilots and WSOs in Maritime Air Superiority in the carrier group arena.
