ABSTRACT

The Tactical Air Launched Decoy (TALD) is a single stage rocket without warhead as

a payload. TALD is an air launched, preprogrammed, unpowered, glide chaff, RFpassive, or RF active vehicle used to deceive and saturate enemy integrated airdefenses during strike aircraft operations. It used in offensive operations againstenemy air defense system by diluting and confusing surface-based and airbornedefenses with realistic tactical target characteristics.

INTRODUCTION

The Tactical Air-Launched Decoy (TALD)/Improved TALD (ITALD) heavyglide/boosted family of passive/active decoys are expendable decoys used inoffensive operations against enemy air defense systems by diluting and confusingsurface-based and airborne defenses with realistic tactical target characteristics. TheTALD is an air-launched, aerodynamic vehicle whose purpose is to minimize theeffectiveness of an enemy's air defense system. The TALD is a preprogrammedglide vehicle used to increase the survivability of strike aircraft. The Improved TALD(ITALD) is a TALD which incorporates a propulsion unit. Both systems operate asexpendable vehicles with no recovery capabilities. Launch platforms include the F/A-18, F-14, EA-6B, and the P-3.

Tactical Air Launched Decoy (TALD)

The TALD is an air launched, preprogrammed, unpowered, glide chaff, RF passive,

or RF active vehicle used to deceive and saturate enemy integrated air defensesduring strike aircraft operations. The three operational TALD configurations include,the A/B37U-1 (V1) chaff vehicle, A/B37U-1 (V2) radar passive vehicle and the ADM-141A radar active vehicle. While fit, form and function remain the same withinversion, manufacturing differences have produced variants.

During Operation Desert Storm one effective tactic to fool enemy air defensesinvolved Navy and Marine Corps (USMC) tactical air launched decoys. The decoyscaused Iraqi defenders to turn on their radars, revealing their locations and makingthem vulnerable to Coalition SEAD aircraft. The tactic confused the Iraqis and helpeddivert their defensive effort. In the early days of the air campaign, EA-6Bs, A-6Es,and F/A-18s escorted large strike packages into southern Iraq. The F/A-18s, A-6Es,

A-7s, and S-3s successfully used TALDs to saturate, confuse, and deceive the airdefense system. This tandem combination of soft and hard kill capability provedsuccessful - no Coalition losses to radar-guided SAMs occurred during SEAD escort.

Improved Tactical Air Launched Decoy (ITALD)

The ITALD is an air launched, preprogrammed, powered RF active vehicle used to

deceive and saturate enemy integrated air defenses during strike aircraft operations.It is a Preplaned Product Improvement towhead that adds turbojet propulsion andlow-level navigation capability to the TALD.

Its official designation is ADM-141C. All four versions are compatible with and can belaunched from the A/A37B-6E Multiple Ejector Rack (MER), A/A37B-5E TripleEjector Rack (TER) or a BRU-42 Improved Triple Ejector Rack (ITER). All versionsare approximately 92 inches long with a nominal 10 inches include width and height.The chaff vehicle weighs approximately 380 pounds, while all RF passive and activeversions weight approximately 400 pounds. A computer within each vehicle ispreprogrammed with flight profile data prior to loading. It provides flight managementand controls of the vehicle through a series of planned maneuvers after launch. TheITALD has enhanced terrain tracking capability and an extended flight envelope forexpanded missions.

The Improved Tactical Airlaunch Decoy (ITALD) simulates a fighter/attack sizeaircraft better than current decoys. The present TALD is becoming less capable evenwhen encountering existing threat integrated air defense systems (IADS).

SPECIFICATION

The basic TALD is an expendable unpowered glide vehicle with a square section

fuselage, flip-out wings, and three tail surfaces. It has a digital flight control systemwhich can be preprogrammed with various speed and manoeuvering profiles.Launched from high-altitude (max. 12200 m (40000 ft)), the TALD has a glide rangeof up to 126 km (68 nm), while the range at lower altitudes of about 600 m (2000 ft)is still around 26 km (14 nm).

Configuration Identification of the Tactical Air Launched Decoy

The TALD is an aircraft-launched, pre-programmed, autopilot guided, unpowered

slide vehicle, which can be fitted with two payloads:

A Radar Cross Section (RCS) Enhancement Payload A Chaff Payload Capable of Dispersing Chaff in a nearly continuous fashion

The TALD vehicle is compatible with TER/MER/I-TER launch equipment, and doesnot require any modifications in the delivery aircraft. the TALD vehicle with the radar

decoy payload (TALDr) employs a forward passive augmentor payload mounted inthe nose cone. an active rf electronic repeater system, consisting of receiving andtransmitting antennae and separate band amplifiers can be installed if required. theTALD vehicle with the chaff payload (TALDc) contains a packaged chaff payload anda dispensing system which will disperse chaff, package-by-package, with severaldispersion rates.

The TALD is of a modular design, permitting easy reconfigurations between theTALDR and TALDC versions, utilizing appropriate payloads. It comprises thefollowing major subsystems/assemblies:

strong back (upper fuselage) with hinged vehicl suspension lugs, wings andwing actuation system;

electronic assembly/digital flight control system (autopilot/programmercomputer, servo and initiation circuitry bite etc.) and associated vehicle powersupply (batteries);

empennage assembly with 'the necessary stabilizing an,[- flight controlsurfaces and actuator assemblies;

The TALDR completion/reconfiguration payload includes the following majorsubsystems/assemblies:

nose cone with the passive augmentor; Lower fuselage. Active RF repeater if required.

The TALDC completion/reconfiguration payload includes the following majorsubsystems/assemblies:

nose cone with or without the passive augmentor Lower fuselage with the chaff payload and dispersion mechanism. specific TALD operating and performance features are as follows: Compliance with current military standards for carriage and release.

CONCLUSION

TALD/ ITALD are a modern strategic warfare currently used and developed by

United State (US) and Israel. Its ability to saturated enemy air defence had beenproved during US attack against Iraq. If we manage to developed and study thistechnology, imagine what the possible outcome that we can harvested. With thestudy of this technology we can develop anti-TALD system to protect our air defencefrom enemy threat.
