What is the purpose of the suppression modes?

• A. These modes help with the interoperability of Link 16 (which has a high duty cycle) and ESM (which is designed to be sensitive to emissions)
• B. They manage the suppression state of Link 16 transmissions to avoid ESM interference
• C. They disable all transmissions to ESM
• D. They enable automatic encryption of all Link 16 traffic

Answer: (B)

Suppression modes control when the Link 16 radio emits and when it stays silent. The goal is to limit RF emissions and reduce the chance that adversary sensors, like ESM, detect or track the activity. By managing the suppression state, units can keep operations less visible while still maintaining essential communications. This isn’t about interoperability, turning off all transmissions, or encryption; it’s specifically about adjusting transmissions to avoid detection by ESM.
