Which statement best describes VULOS?

• A. Operates only on VHF frequencies with no SATCOM support
• B. Provides fixed frequency communications over the VHF and UHF frequency bands; operable over dedicated UHF SATCOM channels
• C. Supports satellite internet connectivity
• D. Provides encryption key management for SINCGARS

Answer: (B)

The statement reflects how VULOS operates by combining stable, predefined channels across both VHF and UHF with access to dedicated UHF SATCOM channels. This means you can use fixed frequencies in the VHF and UHF bands for routine, line-of-sight communications, and you also have the ability to switch to satellite-based links when beyond-line-of-sight reach is needed. That combination of fixed-frequency capability across two bands plus SATCOM access is what distinguishes this system from ones that are limited to VHF only, or that provide only satellite internet or crypto/key management functions. The other options don’t fit because they describe capabilities that VULOS does not primarily provide: being limited to VHF with no SATCOM support; offering satellite internet connectivity; or handling encryption key management for SINCGARS.
