Why are reentry vehicles blunt?

The region just behind the wave is a substantial region of subsonic flow. Since these shock waves cause smaller heating of the vehicle than the airflow, the nose of reentry vehicles are made blunt. This causes most of the heat dissipated to surrounding air without transferring through the vehicle structure.

How many SLBM does the US have?
