@BlitzoNo? Because it's not an issue??
If you cannot locate the CVN because plasma is blinding your sensors it is a real problem and renders the DF-21 useless
If you cannot receive datalink updates because the plasma at Mach 10 is impenetrable your ASBM is useless
Here learn about plasma and try and convince yourself that it is not a problem
Reentry communications blackouts
The communications blackouts that affect spacecraft re-entering the Earth's atmosphere, which are also known as radio blackouts, ionization blackouts, or reentry blackouts, are caused by an
envelope of ionized air around the craft, created by the heat from the compression of the atmosphere by the craft. The ionized air interferes with radio signals. For the Mercury, Gemini, and Apollo spacecraft, such communications blackouts lasted for several minutes. Gemini 2, for example, endured such a blackout for four minutes, beginning at 9 minutes 5 seconds into the flight.
