SUU-25 FLARE DISPENSER

Perform loading and unloading of the dispenser in authorized areas only.

Adapter Kits

Install adapter kits on flares as follows:

1. Make sure the timer knob is on safe.

2. Make sure there is no external damage.

3. Check the adapter kit (fig. 13-27) for two green arming caps with serviceable arming lanyards, one white two-piece spacer, and four yellow sealing rings.

4. Rotate the time knob (fig. 13-28) to required setting.

5. Install yellow sealing ring on each end of flare.

6. Connect green arming cap lanyard (fig. 13-29) to timer knob.

7. Install green capon yellow sealing ring.

8. Place the two halves of the white spacer together and install on the aft end of the forward flare (fig. 13-30).

Dispenser Preparation

Prepare dispenser for flare loading as follows:

1. Safety pin and flag installed in safety switch (fig. 13-31).

2. Stepper switch set on safe.

3. Ensure dispenser has been electrically checked.

4. Open breech caps, ensure sleeves are clean.

5. Open four downloading breech caps (fig. 13-32).

Flare Loading Procedures

Load flares into dispenser as follows:

1. Insert forward flare into tube with green arming cap forward, and ensure white spacer is properly seated on yellow sealing ring and centered. Continue to push flare forward, and insert aft flare with green arming cap forward until forward flare is stopped against the expansion chamber.

2. Close aft retaining link and insert shear pin, with head of shear pin in the upward position. Spread shear pin tangs 30 to 40 degrees.

3. Rotate applicable forward retaining lock to locked position.

4. Install shear pin into lock with pinhead forward and spread tangs to 30 to 40 degrees.

5. Install four downloading breech caps and tighten.

6. Mark dispenser with the date loaded, munitions, lot number, timer setting, and electrical test date.

SAFETY PRECAUTIONS

Safety precautions prescribe the minimum requirements and regulations you should observe when

handling ammunition. These regulations may be general in nature or step-by-step procedures. Regardless of the situation, safety precautions must NEVER be ignored or bypassed, even during the simplest ammunition-handling evolutions.

If you are involved in weapons assembly, always review the applicable safety precautions before beginning the evolution. A few of these general safety precautions are as follows:

1. Fuze or defuze (electric fuzes only) bombs in handling rooms or spaces specifically designed for such purposes.

2. Normally, mechanical nose-fuzed, highexplosive bombs are fuzed after the weapon is loaded

on the aircraft. When the aircraft is carrier based, it must be spotted on the flight deck. Exceptions to this rule are authorized when loading bombs that require special fuzing RADHAZ susceptible units, integral fuzing, and all-up-rounds.

3. Detonators, boosters, primers or other firing devices aren't assembled in or removed from bombs unless specifically prescribed for the weapon.

4. Fuzes aren't allowed to accumulate at the fuzing stations. Never stockpile fuzes. They must be withdrawn from stowage on an as needed basis.

5. Never, under any circumstance, try to disassemble or repair a fuze. Also, never try to render inert a live, loaded item of ordnance.

6. Except as authorized by current directives, no attempt should be made to disarm a fuze.

7. Move assembled rocket ammunition to the designated storage area as soon as practicable after completion of assembly operations.

8. Don't make changes or additions to any ordnance or ordnance components without explicit authority from the Naval Air Systems Command.

9. Exercise particular caution when handling rocket motors to avoid propellant grain damage or fracture.

10. Don't connect electrical power or test equipment to a rocket launcher when rockets are installed.

11. Assemble and fuze airborne rockets in a designated assembly area and as close to the time of aircraft rearming as possible.
