What is the required time for sending a FLASH message?

The requirement for sending a FLASH message is indeed 10 minutes or less. FLASH messages are the highest priority communications in the Navy and are reserved for situations that require immediate attention, such as urgent operational or situational reports. The 10-minute timeframe ensures that vital information is relayed swiftly to the appropriate commands or agencies, allowing for quick decision-making and action in critical scenarios. This time sensitivity is crucial in maintaining operational readiness and addressing urgent matters effectively.
