Here you have it, the Pentagon's annual 30-year aviation plan.
Click through the jump to read all about how the Defense Department plans on buying two new VC-25 presidential transports (Air Force One) by the end of this decade, kicking off an effort to replace the ancient T-38 Talon around 2018, new bombers and a fleet of more than 600 UAVs by 2022. Most interestingly, the plan lists an effort to develop a 6th-generation fighter, dubbed F-X, to replace the Air Force's F-22 Raptors and another 6th-gen jet called F/A-XX that's slated to replace the Navy's F/A-18E/F Super Hornet. (H/t to Marcus for pointing this out.)
All in all the document shows that the Pentagon's aviation fleet will grow slightly from 14,340 aircraft today to 14,415 by 2022, with aviation spending totaling about $770 billion during that time.
