The day end of the MK-124 signal produces what type of smoke?

The MK-124 signal is specifically designed for use in maritime distress signaling. When the day end of the MK-124 is deployed, it produces red smoke, which serves a crucial purpose in emergency situations. This red smoke is highly visible against various backgrounds, making it effective for signaling distress to passing vessels or aircraft.

The consistency of the red smoke aids in drawing attention, particularly in daylight conditions where other signal devices may not be as noticeable. The production of red smoke from this device is a standard feature that aligns with its intended use for signaling distress in a maritime environment. This distinct color is universally recognized as a signal of emergency, making it a vital tool for boat crew members in signaling and communication situations.
