F-16C Block 25

The Block 25 F-16C/D aircraft were originally all powered by the Pratt & Whitney F100-PW-200 turbofan, but they have since been upgraded to the -220E standard.

Starting with Block 25, the F-16C and F-16D (as the one-seat and two-seat variants were designated) featured several improvements:

• Northrop Grumman ESSD radar.

The modifications resulted in a maximum take-off weight increase to 43,300lbs (19,640kg).

Externally, the F-16C is almost identical to the F-16A. The only significant external difference is the introduction on the F-16C of an enlarged triangular base or "island" on the rear fuselage leading up to the vertical fin, with a small blade antenna protruding upward from it.

A total of 209 block 25 C-models have been delivered to the USAF. The USAF is the sole user of this block type.
