The wave drag coefficient for a wedge is a dimensionless quantity that characterizes the additional drag experienced by an object moving at supersonic speeds due to the formation of shock waves and wave patterns in the airflow around the object. Wave drag is a type of drag that becomes significant as an object approaches or exceeds the speed of sound.

- Specific heat ratio (γ)
- Mach number of wedge (M1)
- Pressure over the base (p2) in N/m^2
- Freestream static pressure (p1) in N/m^2
