What is the typical range limitation of VHF radio in Navy operations?

In Navy operations, VHF (Very High Frequency) radio typically has a range limitation that falls between 30 to 50 nautical miles under optimal conditions. This range is influenced by factors such as antenna height, transmitter power, and environmental conditions. VHF is commonly used for ship-to-ship and ship-to-shore communications because it provides reliable line-of-sight communication, which is essential for operational coordination and safety at sea.

The range capabilities of VHF make it particularly useful for tactical communications where short to medium distance connectivity is required without the complexity of satellite systems or longer-range HF (High Frequency) radios. The choice of 30 to 50 nautical miles aligns with operational standards and practices observed in the Navy, making it a crucial tool for effective communication during missions.

Factors that could reduce range include obstacles such as terrain or the curvature of the earth, which can limit the effective use of VHF radio. Other choices suggest either a significantly shorter or longer range, which does not align with the established operational capabilities of VHF radio within the Navy.
