Which naval message type requires a reply under 30 minutes?

• A. Flash (z)
• B. Priority (P)
• C. Immediate (O)
• D. Routine (R)

Answer: (C)

When handling naval messages, urgency is tied to both how fast the message must be transmitted and how quickly a response is expected. A Flash message is the most urgent, intended to go out immediately and take priority over almost everything else; it’s about getting the information to the right place right away, not about expecting a prompt reply within a set window. A message with Immediate precedence is used when quick action or a decision is needed, and a reply is expected within a short window—typically around 30 minutes. Priority messages are important and should be delivered promptly, but they do not impose the same tight response time as Immediate, and Routine messages carry the longest timeframes with no requirement for rapid replies. So, the one that requires a reply within 30 minutes is the Immediate type.
