signaling by personnel on land or sea. It is a one hand operable device that emits orange smoke for daytime use and red flare for nighttime use. Burning time for each end is about 20 seconds. Each end has protective plastic caps. The night end has two prominent raised bead circles on the casing that positively identify this end, by the sense of touch, for nighttime use. A label on the outer surface around the whole body of the signal further identifies the smoke (day) and flare (night) ends. The label also gives detailed instructions on how to use the signal. Mk 79 Mod 0 Illumination Signal Kit The Mk 79 Mod 0 illumination signal kit (fig. 8-22) contains a Mk 31 Mod 0 signal projector, a plastic bandoleer that holds seven Mk 80 Mod 0 signals, and an instruction sheet. The kit is designed for use as a distress signaling device. It is small and lightweight for carrying in flight suit pockets or 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 250 to 650 feet. The star burns for at least 4 1/2 seconds. AIRCRAFT-LAUNCHED ILLUMINATION DEVICES The devices discussed in this section are designed to be launched or dropped from aircraft. LUU-2 Aircraft Parachute Flare The LUU-2 aircraft parachute flare (fig. 8-23) is used for nighttime illumination of surface areas in search and attack operations. The flare consists of a candle, parachute assembly, and fuze, which are all encased in a cylindrical aluminum container. The LUU-2 flare is launched from an external launching system, such as a bomb rack or by hand, from an aircraft. The method most often used is the dispenser-launch method. Regardless of the method of launching, exerting pull on the fuze lanyard starts flare operation. After a predetermined delay, a small explosive charge detonates, expelling the candle and parachute from the container. On opening, the main parachute exerts pull on the cables of the suspension/ignition system, igniting the candle. The candle produces about 2 million candlepower. 8-21 IGNITER END SUSPENSION LUG BANDS TIMER GUARD TIMER END TIMER GUARD TAB SUSPENSION LUG BAND TIMER GUARD TIMER KNOB 14 INCHES 10 INCHES ANf0823 Figure 8-23.—LUU-2 aircraft parachute flare with drogue tray.
