AIRCRAFT-LAUNCHED SMOKE AND
FLAME MARKING DEVICES
LEARNING OBJECTIVE: Identify the
physical and functional description of
aircraft-launched smoke and flame marking
devices. Recognize the methods used to launch
them.
Smoke and flame marking devices are pyrotechnic
devices dropped on the ground or on the water’s surface
to emit smoke and/or flame. Reference points
established by these devices serve a variety of purposes.
They can be used to determine wind direction and
approximate velocity, mark the location on the surface
for emergency night landings, establish an initial contact
point for continued search for a submarine, or locate
target areas in antisubmarine warfare.
MK 25 MODS 2 AND 3 MARINE
LOCATION MARKER
The Mk 25 Mods 2 and 3 (fig. 4-9) marine location
markers are launched from aircraft or surface craft.
They are launched from aircraft to provide day or night
reference points for marking the course of enemy
submarines in antisubmarine warfare operations. They
are suitable for any type of sea-surface reference-point
marking that calls for both smoke and flame for a period
of 10 to 20 minutes. Mods 2 and 3 function identically.
The only significant difference is that Mod 2 contains
two seawater-activated batteries and two related squibs
while Mod 3 contains a single battery and squib.
Physical Description
The Mk 25 marker consists of a cylindrical outer
tube about 18.5 inches long and 2.9 inches in diameter.
A valve assembly is fitted into the projecting chimney
at the marker’s nose end. The smoke and flame are
emitted from this opening. At the opposite end is a
Figure 4-9.—Mk 25 marine location marker.
