In SRU search pattern designations, what does the first letter indicate?

• A. The speed of the vessel
• B. The duration of the search
• C. The type of search pattern
• D. The terrain being searched

Answer: (C)

The first letter in SRU search pattern designations signals the geometry of the search plan—the type of search pattern being used (such as expanding/evolving shapes, sectoring, or linear/grid coverage). This tells you the overall approach for how the search area will be covered, independent of how fast you move, how long you search, or what terrain you’re over. Speed, duration, and terrain are important factors, but they’re not encoded by that initial letter; they’re details that define how the chosen pattern is executed.
