With supersonic vehicles developing, wave drag reduction is widely attended by more and more researchers. A two‐dimensional axisymmetric numerical code is used to simulate the effect of laser energy depositions on wave drag. The drag reduction performances due to the laser energy deposition are invested at different flight altitude. The calculated result shows that the bow shock structure of a blunt body is turned into oblique shock due to the interaction between the bow shock and the low density zone. In the condition of same Mach number, at lower altitude, the reference drag is larger because the pressure of low altitude is large. At the same laser energy, with the flight altitude increasing, the normalized drag will decrease, unfortunately the power effectiveness will decrease too.
