EXECUTIVE SUMMARY

This Draft Navy Training System Plan (NTSP) has been developed by the Naval Air Systems Command to identify Manpower, Personnel, and Training requirements associated with Airborne Expendable Countermeasures. Airborne Expendable Countermeasures addressed in this NTSP are currently in the Production, Fielding, Deployment, and Operational Support phase of the Weapons System Acquisition Process. No previous NTSP exists for Airborne Expendable Countermeasures.

Airborne Expendable Countermeasures are electronic warfare devices used for preemptive or terminal protection of aircraft from Radio Frequency (RF) or Infrared (IR) guided missile attack. Countermeasures are grouped into threat categories of RF passive, RF active, or IR, and include decoy flares, chaff, and expendable RF jamming devices. Decoy flares act as decoys for diverting heat seeking missiles, chaff provides a passive jamming action against enemy radar, while expendable jamming devices transmit RF power to counter airborne and land based semi-active radar guided missiles. Countermeasure devices are deployed from fixed or rotary wing aircraft equipped with countermeasure dispensers.

There are no preventive maintenance requirements for Airborne Expendable Countermeasures devices, at organizational, intermediate, or depot maintenance levels. Limited upkeep maintenance consisting of visual inspections, loading and unloading, packaging and unpackaging, and compliance with pertinent technical directives is performed at organizational and intermediate maintenance levels. Preventative maintenance requirements for Airborne Expendable Countermeasure Systems are addressed the applicable aircraft NTSP's. These functions are within the capability of existing aircraft and ordnance Navy Enlisted Classifications and Marine Corps Military Occupational Specialties.

Airborne Expendable Countermeasures do not have any impact on existing manpower requirements for officers, flight crews, or ground crews for squadrons, weapons departments (ashore or afloat), or training activities. All existing manpower is adequate to support Airborne Expendable Countermeasures.

Training for Airborne Expendable Countermeasures is included in formal aviation ordnance training courses or is accomplished as on-the-job training. A Countermeasures and Associated Cartridges safety lesson has been incorporated into the ordnance training track to present hazards associated with handling and storage of Airborne Expendable Countermeasures. This training will beis conducted at Maintenance Training Units, Fleet Replacement Enlisted Skills Training activities, and specific aircraft tactical weapons training schools. Specific training on countermeasure devices applicable to a particular aircraft type is conducted at the squadron level. At this time no new training courses are required.

G. DESCRIPTION OF NEW DEVELOPMENT

1. Functional Description. Airborne Expendable Countermeasures are electronic warfare devices used for preemptive or terminal protection of aircraft from RF or IR guided missile attack. Countermeasures are grouped into threat categories of RF passive, RF active, or IR, and include decoy flares, chaff, and expendable RF jamming devices. Decoy flares act as decoys for diverting heat seeking missiles, chaff provides a passive jamming action against enemy radar, while expendable jamming devices transmit RF power to counter airborne and land based semi-active radar guided missiles. Countermeasure devices are deployed from fixed or rotary wing aircraft equipped with countermeasure dispensers.

a. InfraredInfrared Devices

(1) MK46 MOD 1C Decoy Flare. The MK46 MOD 1C Decoy Flare is a magnesium fueled device which provides self-protection against IR missiles for the A/UH-1, H-46, SH-60, C-130, and P-3C Aircraft. This decoy is ejected from AN/ALE-39 or AN/ALE-47 Countermeasure Dispensers with either a CCU-63/B or CCU-136/A Impulse Cartridge. The MK46 MOD 1C Decoy Flare is being replaced by the MJU-32/B through attrition.

(2) MJU-8/B Decoy Flare. The MJU-8B Decoy Flare was specifically designed to provide self-protection against IR missiles for Naval tactical aircraft. This decoy is ejected from the AN/ALE-39 or AN/ALE-47 Countermeasures Dispensers with either a CCU-63/B or CCU-136/A Impulse Cartridge. The MJU-8/B was replaced by the MJU-8A/B as an approved operational decoy in 1988. Current inventory assets have been restricted to training use only until depleted.

(3) MJU-8A/B Decoy Flare. This decoy was fielded in 1988 as a product improvement to the MJU-8B Decoy Flare. The MJU-8A/B provides self-protection against IR missiles for Naval tactical aircraft and H-53 Helicopters. This decoy is ejected from the AN/ALE-39 or AN/ALE-47 Countermeasure Dispenser with either a CCU-63/B or CCU-136/A Impulse Cartridge. The MJU-8A/B is being replaced by the MJU-38/B through attrition.

(4) MJU-22/B Decoy Flare. The MJU-22/B Decoy Flare is a product improvement to the MJU-8A/B Decoy Device fielded in 1988, and is similar to that flare with the exception of increased length. The MJU-22/B is used by the EA-6B aircraft and provides a greater degree of protection against IR missiles than the MJU-8A/B Decoy. The MJU-22/B is ejected from the AN/ALE-39 D-47 Extended Magazine (Ten Inch) Countermeasures Dispenser using either a CCU-63/B or CCU-136/A Impulse Cartridge.

(5) MJU-27/B Decoy Flare. The MJU-27/B Decoy Device is dispensed from an AN/ALE-39 or AN/ALE-47 Dispenser using either a CCU-63/B or CCU-136/A Impulse Cartridge. The MJU-27/B is still in active inventory and is being replaced by the MJU-27A/B through attrition.

(6) Advanced Strategic and tactical Tactical Expendable):. The ASTE solution program is a multiservice project involving the efforts of the United States Air Force (USAF) and United States Navy (USN) Naval Air Systems Command (NAVAIRNAVAIRSYSCOM) with the USAF having cognizant responsibility for the expendable. ASTE is comprised of three infrared IR decoy configurations. The flares are configured into two groups, the Fighter Group and the Covert Group. Either the Fighter or the Covert Group is dispensed from an AV-8B or F/A-18E/F aircraft utilizing the hybrid AN/ALE-47 dispensing system, under development by the F/A-18E/F program. An MJU-47/B (Kinematic), and MJU-48/B (Companion) flare combination comprises the Fighter Group. The Covert Group is an arrangement of MJU-51/B flares. The MJU-47/B (Kinematic) is a self-propelled infrared IR flare assembly consisting of an outer case, a flare housing with fins and nozzle component and safe and interrupt assembly packaged in a MJU-10 form factor. The MJU-48/B (companion) consists of an outer case, impulse cartridge cup, a mid-spacer with hydrogen and water vapor absorber, a special material payload and an end cap. The sole purpose of the ASTE solution is to redirect incoming missile threats away from the aircraft. The ASTE solution is composed of Non-Developmental Items as well as a redesign effort for the housing and magazines. The redesign modifies the flare casing size and changes the dispenser housing to accommodate the smaller flares. ASTE decoy flares are deployed then actuated by BBU-35/B and BBU-36/B impulse cartridges.

The ASTE solution is capable of deploying a Fighter Group and a Covert Group flare configuration. The group deployed is contingent upon the aircraft platform mission. ASTE is a flare development, not an avionics system. Current planning is for tNAVAIRhe F/A-18E/F and the AV-8B to be equipped with the ASTE solution.

Functionally the ASTE solution will be launched from an AV-8B or F/A-18E/F aircraft using a hybrid AN//ALE-47 Countermeasures Dispensing System (CMDS). When installed in the proper chamber, a corresponding impulse cartridge is installed in a cavity on the breech end of the outer case. Once the impulse cartridge has been initiated from the firing pulse, in the Fighter Group a frangible membrane ruptures and gas pressurizes the outer case. The flare housing and end cap are ejected from the outer case by gas pressure. The slider interrupter prevents the hot gas from igniting the flare assembly prior to clearing the outer case. When clear of the outer case, the slider interrupter allows ignition of the flare assembly. Following ejection, the flare assembly is stabilized by fins, and, upon exposure to the air stream, causes the nose of the flare to point into the wind on a trajectory which approximately parallels that of the aircraft. The burning pellet produces hot gases, which generate radiant infraredIR energy (used to decoy the threat seeker), and thrust, which powers the flare on the desired trajectory. The Covert Group flare functions when the impulse cartridge is initiated by the firing pulse, a frangible membrane ruptures; and the pressure inside the canister increases. A piston drives the special material payload the length of the canister. The force of the payload pushing on the closure disk breaks the seal and propels the payload into the atmosphere where the payload reacts with the air to emit infraredIR radiation.

(7) MJU-49/B Decoy Device. The MJU-49/B decoy device is an IR decoy, providing aircraft survivability and protection against IR guided threats. It was designed to increase the survivability of helicopters and low/slow fixed wing aircraft. It is intended as an improvement over the performance of the MJU-27A/B decoy when used either singly or in combination with other Infrared Countermeasure (IRCM) on helicopters and low/slow fixed wing aircraft. The MJU-49/B decoy device consists of a cylindrical cartridge approximately 1.4 inches in diameter and 5.8 inches in length. The decoy is used in either the ASN/ALE-39 or the AN/ALE-47 CMDS, the payload being dispensed by either a CCU-63/B or CCU-136/A impulse Cartridge. The IR payload produces significant amounts of energy to decoy threats that operate within the 2-5 micrometer wavelength portion of the spectrum. The decoy consists of an appropriate amount of a special type of IR material which, when expelled from the sealed container, performs similarly to the MJU-27A/B decoy by generating heat through a pyrophoric process.

(8) MJU-47/B Kinematic Decoy Flare:.. Prototype development of the Kinematic Decoy Flare began in January 1989. Currently, a joint Navy USN and Air ForceUSAF Program, Advanced Strategic and Tactical Infrared ExpendablesASTE is underway for commercial development and production of a comparable item. The MJU-48 and MJU-51 Decoy Flares are companion devices to the MJU-47/B.

(9) MJU-49/B Decoy Device. The MJU-49/B decoy device is an IR decoy, providing aircraft survivability and protection against IR guided threats. It was designed to increase the survivability of helicopters and low/slow fixed wing aircraft. It is intended as an improvement over the performance of the MJU-27A/B decoy when used either singly or in combination with other IRCM on helicopters and low/slow fixed wing aircraft. The MJU-49/B decoy device consists of a cylindrical cartridge approximately 1.4 inches in diameter and 5.8 inches in length. The decoy is used in either the ASN/ALE-39 or the AN/ALE-47 CMDS, the payload being dispensed by either a CCU-63/B or CCU-136/A impulse Cartridge. The IR payload produces significant amounts of energy to decoy threats that operate within the 2-5 micrometer wavelength portion of the spectrum. The decoy consists of an appropriate amount of a special type of IR material which, when expelled from the sealed container, performs similarly to the MJU-27A/B decoy by generating heat through a pyrophoric process.

(10) MJU-35/B Decoy Flare. MJU-35/B decoy device is an extended length infrared IR decoy product improvement to the MJU-27/B decoy. The decoy provides improved IR output and better protection for high IR signature aircraft. The MJU-35/B contains the same proprietary material as the MJU-27/B and is dimensionally the same except for its extended length. The MJU-35/B has a hazard classification of 4.2G (spontaneously combustible) versus a standard conventional infrared IR decoy, which is 1.3. G. The flare consists of a cylindrical aluminum case approximately 1.42 inches in diameter, 8.1 Iinches long (versus 5.8 InchesInches for the MJU-27/B). The MJU-35/B is designed for the 8.1 inch length AN/ALE-47 CMDS. The only difference between the MJU-35/B and the MJU-27A/B is the length. Based on Direction from the Office of the Secretary of Defense (OSD)/N78 all future IR countermeasures developments for all future aircraft will require joint Air Force/Navy utilization. Therefore, the MJU-35/B is being replaced with an MJU-7A/B form factor (1x2x8.1"inches).

(11) MJU-36/B Decoy Device. The MJU-36/B infraredIR decoy is an extended length infraredIR decoy product improvement to the MJU-8A/B decoy. The MJU-36/B provides improved safety features and takes advantage of the extended length available to provide better protection for high IR signature aircraft. The only difference between the MJU-38/B and the MJU-36/B is the length. The MJU-36/B is designed for the 8.1"inches Length AM/ALE-47 CMDS used on the F/A-18E/F during Operational Evaluation (OPEVAL). Based on direction from OSD/N78 all future IR countermeasure developments for future aircraft will require joint Air Force/Navy utilization. Therefore, the F/A-18E/F the MJU-36/B is being replaced with an MJU-7A/B form factor (1x2x8.1"inches) magnesium based flare. The basic design and functional sequence of the MJU-36/B is similar to that of the MJU-32/B and MJU-38/B, using the sympathetically ignited, boreriding slider/initiator. The MJU-36/B was initially presented to the Weapons System Explosive Safety Review Board (WSESRB) on 23 May 1996. WSESRB approved the system Safety Plan and provided criteria for development plan approval.

(12) . MJU-52/B Decoy Device. The MJU-52/B (BOL-IR) decoy is an IR decoy, providing enhanced aircraft survivability and protection against IR guided Threats. It was designed to increase the survivability of aircraft capable of carrying the LAU-138A/A Guided Missile Launcher Set BOL dispenser (or its derivatives). The dispenser's currently loaded with 160 chaff cassettes that are dispensed from the BOL by an electro-mechanical gear movement. It is intended the MJU-52/B serve as an improvement over the existing BOL-ALE-39 combination of dispensers by allowing the aircraft commander greater flexibility in optimizing his countermeasure load-out to defeat specific mission threats. The decoy consists of a modified BOL chaff plastic cartridge that houses an IR payload. The IR payload produces a specific amount of IR energy in the 2-5 micrometerwavelength portion of the spectrum. The decoy consists of an appropriate amount of a special IR material, which when expelled from the sealed container, performs similarly to the MJU-27A/B decoy flare by generating heat through a pyrophoric process. The MJU-52/B utilizes the same flatpacks as the BOL chaff to facilitate operational use of the BOL dispenser. The difference between the RF and IR packages revolves around the different payload of the decoy devices. The BOL IR payload is pyrophoric metal (Special Material) which must be contained within an air-tight, sealed package. The operation of the dispenser and the release of the package is the same as with BOL chaff. The BOL IR payload packet seal contains an integral tear strip which is attached to the encapsulating flatback. When released into the air stream the flatpack acts as a parachute due to the relative drag between the payload packet and the flat pack. This drag force, tears open the seal of the payload packet and the pyrophoric payload is released to the air stream, dispensing aerodynamically in the same manner as the chaff.

The AN/ALE-41 is a roll type dispenser for chaff corridor seeding and has dipoles rolled between two layers of mylar film into a sandwich approximately 0.2 inches thick, twelve inches wide and 100 feet long. The rolls are unwound in a ram air pressurized external store with the two mylar films separated over a slot in a tube extending out the aft end of the store. The released dipoles are instantly drawn into the tube and continuously ejected from the tube into the boundary layer. No pyrotechnics are involved.

(5) AN/ALE-43(V) Chaff Dispenser (Pod). The AN/ALE-43(V) is a bulk chaff dispenser, which cuts chaff dipoles from fiberglass roving. This dispenser is a pod configuration and has an eight package capacity. The cutting mechanism contains a rubber platen roller and three cutter rollers which yield three in-flight selectable combinations of dipole lengths. The chaff is dispensed when the rovings are drawn simultaneously from each roving package, cut to length and discharged into the wind stream. No pyrotechnics are involved.

(6) AN/ALE-47 Dispenser. The AN/ALE-47 Dispenser is an upgrade to and eventual replacement for the AN/ALE-39 Dispenser. The AN/ALE-47 has the capability of dispensing flares, chaff, non-programmable expendable jammers, and programmable jammers. The system consists of a Cockpit Control Unit, Programmer, Sequencer Switch, and Dispenser Assembly, which will program and eject specific expendable countermeasures in response to various threats.

3. New Development Introduction

a. MJU-32/B Decoy Flare. A PIP associated with the MK 46 MOD 1C was initiated to improve the integrity of the outer case and provide a safer ignition system. The Engineering Change Proposal (ECP) was signed in June 1996 and production began in fourth quarter FY96. The MK 46 MOD1C will be replaced through attrition by the MJU-32/B.

b. MJU-38/B Decoy Flare. A PIP was initiated on the MJU-8/A Decoy Flare to reduce production costs and enhance safety. The grain configuration was changed for more efficient production while maintaining the existing IR time and intensity profile. The outer case, end cap, and igniter were all modified to enhance safety. The ECP was signed in June 1995 and procurement implemented in FY96. The MJU-8/A Decoy Flare will be replaced through attrition by the MJU-38/B Decoy Flare.

c. SM-875A/ALE Flare Simulator. The SM-875/ALE Flare Simulator, was reconfigured to reduce the number of internal components, enhance flare ignition, and was increased in length to make it the same as all other decoys, ( for better/safe3r visual inspection by ordnance personnel during turnaround operations. This new device, nomenclature SM-875A/ALE is beingwas procured in FY98 for replacement of the current SM-875/ALE simulator Flares.

d. MJU-35/B Decoy Flare. The MJU-35/B Decoy Flare is the nomenclature assigned to a product improvement associated with the MJU-27/B Decoy Flare. The ECP provides for additional payload material to increase the IR output and to allow compatibility with an 8.1 inch dispenser being fitted for the F/A 18 E/F Aircraft. Procurement began in FY98.

e. MJU-36/B Decoy Flare. A product improvement associated with the MJU-8A/B was initiated to provide a higher intensity decoy for the F/A 18E/F Aircraft. The flare uses conventional composition and is 8.1 inches long and 1.42 inches in diameter. Qualification tests were initiated in the fourth quarter FY95 and were completed in the second quarter FY96. Production began the third quarter FY98.

f. MJU-27A/B Decoy Device. The MJU-27A/B Decoy Device is a PIP to the MJU-27/B. This decoy is dispensed from either an AN/ALE-39 or AN/ALE-47 Dispenser using a CCU-63/B or CCU-136/A Impulse Cartridge. The MJU-27A/B is being procured and will replace the MJU-27/B through attrition.

4. Significant Interfaces. Airborne Expendable Countermeasures are launched from AN/ALE-29A, AN/ALE-37A, AN/ALE-39, AN/ALE-41, AN/ALE-43, and AN/ALE-47 Countermeasure Dispensers. With the exception of the LAU-10 and LAU-138/BOL, dispensing is initiated by the firing of an impulse cartridge. These devices are usable with fixed and rotary wing aircraft capable of employing Airborne Expendable Countermeasures. The following shows individual countermeasure devices and associated dispensers, Naval Ammunition Logistic Codes (NALCs), impulse cartridges, and aircraft applications.
