What is the approximate weight of the LUU-2B/B aircraft parachute flare? The components of the LUU-2B/B flare are What is the minimum drop distance setting of the LUU-2B/B flare? What is the diameter of the parachute suspension system? At launch, the timer knob is pulled off of the timer by what amount of force on the lanyard? Using the LUU-2B/B flare instead of the Mk 45 Mod 0 flare is more advantageous because the LUU-2B/B flare candle ________________. 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. 4-9
