Unit Specific 204
The following system components and component parts are discussed below mentioning their function, location, and how many are available.
204.1.1 Bomb bay weapons stations.
The P-3 bombay consists of a maximum of 8 stations for loading weapons (4-upper & 4-lower). The maximum amount of "Charlie" stations is 3.
204.1.2 Wing weapons stations:
Pylons- used to suspend launchers or bombs from the aircraft wings, fuselage or bomb bay.
- Bomb rack (BRU-15)- aircraft bombs, torpedoes, mines, missile and other stores are suspended internally or externally from pylons by bomb racks. Bomb racks carry, arm and release stores.
204.1.3 Search stores delivery subsystems:
Internal launch tubes- consists of 3 pressurized tubes for launching sonobuoys.
- External launch tubes- consists of 48 non-pressurized tubes for launching sonobuoys.
- Free-fall chute- consists of a single chute located aft of the 3 PSLTs. A protective sleeve is required to be inserted into the free-fall chute prior to usage. This will illiminate damage to the aft undersection of the aircraft.
204.1.4 Countermeasures equipment:
AN/ALE-29 dispenser module- the AN-ALE-39 Countermeasures Dispensing System (CMDS), in conjunction with ehe AN/AAR-47 Missile Warning Set (MWS), is designed to provide protection for the P-3C from missile attacks. The CMDS, when fully operational, can dispense up to 60 passive radar decoy (chaff) cartridges, infrared decoy (flare) cartridges, or electronic (jammer) cartridges. This system, however, is not presently configured to dispense active jammers.
204.5.1 What special safety precautions apply to:
Bomb bay doors operation-
Operation of the bomb bay doors when personnel or
equipment are in the vacinity of the doors can cause death or serious
injury to personnel and damage to equipment.
Anytime the bomb bay doors are open and hydraulic power is required, an outside observer shall be posted to ensure that the bomb bay area remains clear.
2. Sonobuoy safety switch-
Prior to walking under (loading, unloading, inspection, and so forth) external SLTs, ensure sono safety switch door is open, roller switch is fully extended, and SONO DISABLED light in cockpit is illuminated. If sono safety switch door is closed, ensure an ourside observer is posted to prevent personnel from entering sono launch area.
3. Countermeasures dispenser-
Safe the MCDS prior to securing power to the MWS to preclude a possible inadvertant command countermeasures signal from dispensing a countermeasure.
