1. Lockheed Martin F-22 Raptor: The F-22 Raptor has a maximum speed of Mach 2.25, which is approximately 1,500 miles per hour (mph) at sea level.
2. Lockheed Martin F-35 Lightning II: The F-35 Lightning II has a maximum speed of Mach 1.6, which is approximately 1,200 mph at sea level.
3. Boeing F-15 Eagle: The F-15 Eagle has a maximum speed of Mach 2.5, which is approximately 1,650 mph at sea level.
4. Boeing F/A-18 Super Hornet: The F/A-18 Super Hornet has a maximum speed of Mach 1.8, which is approximately 1,320 mph at sea level.
5. Northrop Grumman B-2 Spirit: The B-2 Spirit stealth bomber has a maximum speed of Mach 0.95, which is approximately 630 mph at sea level.
It's worth noting that these are the maximum speeds achieved under optimal conditions. In reality, the top speed of a fighter jet can be affected by factors such as altitude, weight, payload, and atmospheric conditions.
