On a MK46 REXTORP torpedo, what does a blue stripe indicate?

• A. Operational
• B. Maintenance
• C. Training
• D. Decommissioned

Answer: (C)

Blue stripe shows the round is configured for training. In naval ordnance, color bands convey status at a glance, and blue is used to mark training or non-operational ammo. That means the torpedo is intended for exercises rather than combat use, helping crews handle it safely and preventing it from being loaded into a launcher as a live weapon. Operational rounds would carry markings indicating readiness for combat, while maintenance or decommissioned rounds have different indicators and procedures. So the blue stripe best indicates training.
