PLEASE NOTE:  This table is NOT 100% definitive and it is subject to change.  Combat aircraft performance specifications are not always indicative of their combat ability, and much information is classified.  This information is provided as a "rough guide" only.  Whenever possible, the data provided is based on the manufacturer's specifications.  Otherwise, data in this table has been confirmed with at least two separate sources.

ALSO NOTE:  This table may found elsewhere in this site.  If there is a discrepancy, the table found under the quick link at the top of the page should be considered to be the most current and accurate.

1Unofficially, the F-35 can supercruise at mach 1.2 for a distance of 241km.
2External fuel tanks are planned for the F-35, but none have been flight tested yet.
3The F-35 has only been tested to 43,000ft so far.
4Gripen C information, Gripen E data is unavailable


So how do the F-35, Gripen E, Typhoon, Rafale, and Super Hornet compare to each other?  As you can see, some of the specifications are quite close, others have very obvious differences.  It must be stated, however, that this comparison doesn't look at the complete picture.  There are other performance parameters, like instantaneous turn rate, sustained g performance, and acceleration that are just as important, but harder to research.  

This information was as accurate and as current as I could find.  Some data on the F-35 is still "classified", while other figures are specified, but not yet tested.  The Gripen E has a similar issue, but some information is confirmed thanks to the Gripen NG demonstrator aircraft.  The Gripen E will have a higher weight than the C model, but has a substantially more powerful engine to compensate.

Some things to note:
  • The F-35's wing loading and thrust-to-weight ratios aren't even close to the others.
  • The Gripen, Typhoon, and Rafale are quite similar, performance wise.
  • The Gripen's small size keeps it from carrying heavier payloads (it carries as much as the current CF-18), but otherwise, its performance is very similar, if not superior, to the others.
  • Despite its greater payload capability, the F-35 is limited by its 10 weapon hardpoints, the same as the much smaller Gripen.
  • The Rafale's supercruise performance seems...  Optimistic.
  • The Super Hornet really doesn't improve much on the classic CF-18 Hornet as far as performance goes.  It does hold more payload and has a lot more advanced gear though.
  • The F-35 does not have a 2 seater variant suitable for training or advanced combat roles (weapons officer, UCAV command, etc).
