What does 'Romeo' indicate in naval terms?

In naval terms, 'Romeo' is a signal that indicates a ship is preparing to replenish, typically referring to the transfer of fuel, supplies, or ammunition at sea. This signal is part of the International Code of Signals, which aids in communication between vessels, especially when visual signals are being used. Understanding these signals is crucial for safe and effective maritime operations, particularly during replenishment at sea, as it helps coordinate activities and maintain situational awareness among vessels in close proximity. This specific use of 'Romeo' aligns with naval protocols and ensures that ships are prepared for the logistical support they require while on deployment.
