What is the maximum distance offshore for the RBS II?

• A. 2 NM
• B. 5 NM
• C. 10 NM
• D. 20 NM

Answer: (C)

The distance offshore for the RBS II is limited by its design to keep operations within a safe, controllable range from shore. Ten nautical miles provides a practical balance between staying within reasonable fuel and endurance limits, keeping radios and visual contact with shore-based resources reliable, and still allowing safe return and maneuvering in typical nearshore conditions. Going only a few miles out would be overly restrictive for missions, while venturing farther—like twenty miles—could exceed the boat’s endurance and communications margin given standard crew and equipment. So, ten nautical miles is the established maximum.
