Although the slogan of the F-15's original design team was "Not a pound for air-to-ground," the F-15 has long been recognized as having superior potential in the ground attack role. In 1987 this potential was realized in the form of the F-15E Strike Eagle. The mission of the Strike Eagle is as succinct as that of its air-to-air cousin: to put bombs on target. The F-15E is especially configured for the deep strike mission, venturing far behind enemy lines to attack high value targets with a variety of munitions. The Strike Eagle accomplishes this mission by expanding on the capabilities of the air superiority F-15, adding a rear seat WSO (Weapon Systems Operator) crewmember and incorporating an entirely new suite of air-to-ground avionics
