[quote="Bean 2":3d20e]Does anyone know the difference between the X-35 and the F-22 Raptor?[/quote:3d20e]

totally different machines,
the F-22 is a twin-engine US Air Force air superiority fighter,
the F-35 is a Air Force, Navy, and Marine multi-purpose single-engine fighter (fighter-bomber really).
The various branches will have slightly different versions, the Navy's version is reinforced to carrier landing, the Marine version has a lift fan for V-TOL, the Air Force version isn't burdened by these things and can carry more weapons or have better performance with same weapons.
