How long does each end of the MK-124 burn?

The MK-124 is a signal kit used for signaling and communications while at sea, featuring two ends that serve different purposes. The correct duration for each end of the MK-124 to burn is between 16 to 20 seconds. This time frame is critical for users to know, as it allows them to plan and execute signaling properly and ensure effective communication in emergency situations or during maneuvers requiring recognition.

Understanding this specific burn duration is essential for training and safety, as improper use or miscalculation of how long the signal will last could lead to ineffective signaling in critical situations. The other options do not accurately represent the established burning times of the MK-124 signals, which are extensively tested and documented for operational use.
