The Block 52 F-16C contains a Pratt and Whitney F100-PW-229 afterburning turbofan engine. These provide up to 29,160 foot lbs of thrust with the afterburner in an aircraft that weighs nearly 19,000 lbs empty. This gives it the ability to climb vertically if need be and reach mach 2+ in level flight. The F-16 is a small aircraft by modern fighter standards at only 49.5 feet in length and 31 feet in wingspan. The F-15, for example, is more than ten feet larger in both length and span.
