At what altitudes does the MK-127 reach?

The MK-127 is an aerial flare used primarily by the Coast Guard and other maritime agencies for signaling and illumination. When deployed, it typically reaches a peak altitude in the range of 650 to 700 feet. This altitude ensures that the flare can sufficiently illuminate a wide area for visual signaling while remaining safe and manageable for the operators.

The choice of 650-700 feet as the correct altitude range reflects both the operational capabilities of the MK-127 and the practical needs for search and rescue operations, where visibility can be crucial. This range allows for effective signaling while ensuring that the flare's descent is controlled and that it burns for a sufficient amount of time to be seen by rescuers or individuals in distress.

Other altitude ranges provided in the options do not align with the operational specifications of the MK-127 and therefore are not accurate for this particular flare. Each of those ranges would either indicate a height that is too low or too high based on its design and intended application.
