There isn’t any “F” model.

A— original fighter model (most are out of service)
B — 2 seat trainer/fighter
C — current single seat fighter
D — 2 seat version of C
E — Strike Eagle fighter/bomber
K — Korean model

There was a grounding of the F-15 fleet a couple weeks ago due to a crash that may have been related to structural fatigue.

[null and void]

My error, should be A-D grounded, F OK to fly.
