1. F-15C Eagle (clean configuration, sea level): Approximately 180 knots (207 mph, 333 km/h)
2. F-15E Strike Eagle (clean configuration, sea level): Approximately 195 knots (224 mph, 360 km/h)
When the aircraft is in a landing configuration (with flaps and landing gear extended), the stall speed increases. For example, the F-15C Eagle might have a stall speed of around 135 knots (155 mph, 250 km/h) in a landing configuration.
It's important to note that these are approximate values, and the actual stall speed can vary depending on specific circumstances and the pilot's inputs.
