The Eagle is a Mach 2.5+ fighter (1,650+ miles per hour/2,665+ kilometers per hour). Its service ceiling is 65,000 feet (19,812 meters) and it could climb in excess of 50,000 feet per minute (254 meters per second). With a thrust-to-weight ration of 1.15:1, The F-15 could climb straight up.
The Eagle’s combat radius is 1,222 miles (1,967 kilometers).
