The F-15A is a big aircraft, inescapably given its load and range
requirements, featuring a central fuselage with Pratt & Whitney F100-PW-100
turbofans on each side; wedge-shaped clipped wings with a sweep of 45
degrees; all-moving horizontal tailplanes; twin vertical tailfins; and
tricycle landing gear.
Each of the two engines provides 65.26 kN (6,650 kgp / 14,670 lbf) maximum
dry thrust and 106 kN (10,800 kgp / 23,830 lbf) afterburning thrust. The
aircraft consists of 37.3% aluminum, 25.8% titanium, and 5.5% steel by
weight, with selective use of composite materials.
