The list of units
Jet Fighters are faster versions of their predecessor. They may execute all air missions except precision strikes. Jet Fighters have radar that allows the unit to "see" two squares regardless of blocking terrain. They may be based in any city or aircraft carrier on the map.
A city needs oil and aluminum in its Strategic Resource box to build a jet fighter.
The introduction of jet engines to fighter aircraft changed the way man wages war in the skies. The primary impact was that of speed, since even early jet engines were able to outperform their rotary peers by three to one. While this improvement was certainly appreciated by their pilots (speed advantages often translate to more options in air combat), it was some time before the nature of this change was fully understood. Dogfighting became a significantly more difficult task, since the window to 'take a shot' was reduced to an instant. The introduction of guided missiles helped address this, as well as increase engagement ranges to beyond what the pilot could visually see. Though missiles dramatically changed air combat, cannons still remained a staple of the vehicles' arsenal. Missiles could be jammed, and early attempts were frought with unreliability. Without a backup weapon, pilots were often at the mercy of inferior planes, but ones where the pilot wasn't relying on shaky, emerging technologies.
