What is the primary EHF System?

• A. MILSTAR
• B. SHF-Overseas
• C. JCSAT
• D. DSCS

Answer: (A)

Extremely High Frequency communications are designed to stay reliable even under heavy jamming and in contested environments, offering secure, survivable links for military use. MILSTAR was built specifically to provide protected, jam-resistant communications in the EHF band, including capabilities like crosslinks and highly secure terminals to maintain connectivity when other channels fail. The other options operate in different bands—SHF or commercial systems—and don’t provide the same level of EHF-protected capability. That combination of purpose-built protection and EHF performance makes MILSTAR the primary EHF system.
