devices are capable of firing various types of marine
signaling devices. Refer to table 4-1.
MK 13 MOD 0 MARINE SMOKE AND
ILLUMINATION SIGNAL
The Mk 13 Mod 0 (fig. 4-4) is used as a day or night
signal by personnel on land or sea. Because of its small
size and weight (6.4 ounces), it can be carried in life
vests or flight suit pockets and on life rafts. This signal
is especially adapted for use by aircrew personnel
downed at sea.
The Mk 13 Mod 0 signal is a metal cylinder
approximately 5 inches long and slightly more than 1.5
inches in diameter. It emits orange smoke for day use
and red flame for night use. Burning time for each end
is about 20 seconds. The protective plastic cap on the
flame (night) end is molded so there are three
prominent protrusions or beads across the face. You can
identify this end by the sense of touch. The face of the
cap at the smoke (day) end is smooth. A label on the
outer surface around the whole body of the signal
further identifies the smoke (day) and flame (night)
ends. This label has instructions for its use.
To use the signal, remove the plastic cap from the
end of the signal. Flip the pull ring over the signal rim
and push downward to break the seal. After the seal is
broken, NEVER point the signal toward your face or
body. Then, ignite the signal with a quick pull on the
ring. Hold the signal firmly at arm's length and at a
45-degree angle to prevent burns from hot drippings. If
you only use one end, douse the signal in water to cool
it. Save the other end for later use.
MK 79 MOD 0 ILLUMINATION SIGNAL
KIT
The Mk 79 Mod 0 signal kit (fig. 4-5) consists of a
Mk 31 Mod 0 signal projector, a plastic bandoleer that
holds seven Mk 80 Mod 0 signals, and an instruction
sheet.

distress-
signaling device kits. Because it is small and
lightweight, personnel can carry it in pockets of flight
suits or in life rafts. The projector aims and fires the
signals. Each signal contains a single red star. On
activation, this star is propelled upward to a height of
between 250 and 650 feet. The star burns for a
minimum of 4 1/2 seconds.
To operate the device, you cock the projector firing
pin by moving the trigger screw to the bottom of the
vertical slot, and slip it to the right so that it catches at
the top of the angular slot. After cocking the firing pin,
remove a signal from the bandoleer and mate the
projector with the signal. Now, rotate the projector
clockwise until the signal is seated. Hold the projector
overhead, pointed at a slight angle away from your
body. While firmly gripping the projector, fire the
