The F-15 Eagle is equipped with this version of the ACES II. It replaced an Escapac
seat used in the prototypes and early F-15A aircraft. This version differs from the rest of
the basic side-pull ACES II seats (A-10, F-117) in the configuration of the headrest canopy breakers, and the side-pull handles.
The A-10 seats originally had no canopy breakers as in the example shown, but were later fit with a single canopy breaker. The canopy breakers
were introduced after a mishap where the fractions of a second saved by going through the canopy rather than waiting for it to jettison could save a life.
See the story Back in the Saddle for an instance like that.
The F-117 has a metal canopy frame which precludes the use of a canopy breaker. The handles on the F-117 closely resemble the A-10 handles.
