Comment on Drag race: hypersonic threats are slow enough for US missile defenses

  I get what you’re saying, but wouldn’t the impact speed be it’s highest speed? I really don’t know.

    It depends because some missiles don’t hit targets while the rocket engine is running. Often the rocket engine sends the rocket into a parabolic trajectory and shuts off at the peak altitude and then it coasts to the target while moving to avoid AA. HIMARS does that but there are missiles that don’t, but they aren’t labelled hypersonic like the javelin.

    The idea behind hypersonic is that’s it’s always at hypersonic speeds which means very hard to intercept. Half hypersonic is how many missles works.

      Yea, I just assumed the engine wouldn’t be very useful much past apogee, and (again) assumed they were utilizing gravity at that point to continue acceleration. But then again I haven’t really read up on them.

      Fine, I’ll go read now. Obviously I need to educate myself. Lol.

      Thanks
