SPECIAL REPORT: NEXT GENERATION AIR AND NAVAL COUNTERMEASURES
Anti-Piracy & Trafficking Deterrent 26mm Chaff countermeasure dispenser.
IR flares provide helicopters, fast jets and transport aircraft effective protection from missile attack.
Together with Wallop’s sister company Armtec, their advanced designs are in service on a wide number of fixed and rotary wing platforms across the globe. Many dispensers are serviced including the ALE-47, ALE-40, ALE-29/39, SAAB (BOZ, PHIMAT), M-130 and Thales Vicon 78. As well as supplying chaff payloads for use on Western aircraft, Wallop supplies 26mm for use on FSU aircraft including the Mi-8 helicopter and a variety of MiG fighters. 50mm decoys are supplied for use on Sukhoi and IL-76 aircraft.
Millimetric Chaff Decoys parent group, Esterline, meets the exacting US Weapons Specifications, and provides enhanced decoy radar cross sections which, in turn, distract and seduce incoming missiles away from their threatened targets. To combat the multi-frequency bands that modern missiles can use, chaff systems offer Broadband frequency protection whilst providing an excellent radar cross section. Through the use of advanced design and manufacturing techniques, modern chaff systems ensure decoys bloom very rapidly with minimal bird-nesting which significantly enhances the aircraft’s survivability and operational effectiveness. Wallop Defence Systems provides a comprehensive range of chaff products that are reliable and well-proven, having been originally developed in partnership with the UK MoD. The Company has an extensive Research & Development capability which creates chaff payload designs across the RF spectrum tailored to meet customers’ individual operating requirements. The WDS RR-180 chaff cartridge supplied by Wallop provides dual-shot capability effectively doubling the number of countermeasures carried by the aircraft.
A chaff decoy is a cloud of resonant metallic dipoles. Consequently, when designing a chaff decoy, the aim is to produce the least dense chaff cloud that is practically possible, whilst dispensing a sufficient number of dipoles to achieve the required RCS, given account of mechanical dispensing losses and polarisation effects. Almost all Surface to Air (SAM) missile systems use E to H acquisition and I to J tracking radars. This is why chaff countermeasures such as the RR-170 cartridge invariably specify E/F, G/H and I/J coverage. An important exception is the SA-15 / SA-19 SAM system which uses K-Band with C-band search and I-band command guidance. The provision of K-band millimetric chaff for cartridges such as RR-170 and RR-180 is entirely feasible. The use of fine filament chaff to secure a sufficient RCS overcomes previous problems of obtaining a practical RCS in the region of 30 to 40 GHz, given the small size of the chaff cuts. Specialised naval chaff decoy countermeasures have been developed to counter anti-ship missiles with frequency-agile capability. There is increasing interest in a millimetric capability for naval chaff decoys. Experience from trials indicate that a practical millimetric capability for naval use is probably
