Wallop Defence Systems Ltd, Craydown Lane, Hampshire, England is a division of the Esterline Defense Group with corporate headquarters in the USA. The parent company, Esterline Technical Corporation, is a multi-national operation and has a turnover in excess of $1.5 billion (Rs. 7,000 crore) employing more than 8,000 personnel. Wallop designs and manufactures a range of airborne devices, defence pyrotechnics and naval countermeasure products for use by armed forces and in search and rescue.

Wallop designs, manufactures and supplies a wide range of airborne passive countermeasure chaff (RF) and Infra Red (IR) decoys for use in a wide variety of dispensing systems from both fixed and rotary-wing aircraft. The decoys are tailored to platform, meeting the customer’s individual operating requirements. These decoys are used to defeat both heat-seeking (IR) and radar-guided (RF) missiles. Wallop has over 50 years of experience in designing/manufacturing a wide range of IR flares. We can offer traditional magnesium teflon viton (MTV) flares for use against first generation missiles and advanced dual band spectral flares designed to defeat more advanced missiles.

Wallop’s chaff and flares are suitable for use on both Russian and Western fixed and rotary-wing aircraft including MiG-29, Su-30, Mi-17, Mi-8, AH-64 Apache, CH-47 Chinook, Sea King, Lynx, Super Puma, Panther, Cougar, EH-101, C-130, C-17, CN-295M, C-160, Jaguar, Hawk Mk 132, Tornado, Harrier GR-9, Harrier AV-8B, F-16, F/A-18 and Typhoon. Chaff and flare dispensing systems supported include ALE-40, ALE-47, ALE-29/39, ALE-29A, Thales Vicon 78 CDMS Series, SAAB (BOZ and PHIMAT series) M130, ASO-2V, BVP-30-26M and BVP-50-30 (50mm) APP-50. Cartridges are available in several formats; square, rectangular and cylindrical. All sizes and origin of dispensers can be accommodated. The flares are usually supplied with electric squibs (ignitors) pre-fitted which can be supplied separately as required.

Advanced chaff cartridges are available. The RR-180 cartridge effectively doubles the shots per magazine of ALE-47 and similar dispensers by firing two separate chaff payloads from each chaff cartridge. The standard aluminised glass filaments (chaff) measure 23/25 microns. However, Wallop is able to supply chaff filaments of nominally 17 microns diameter significantly increasing the RCS of the chaff cloud.

Wallop comprehensively supports UK and NATO chaff and flare trials aimed at enhancing platform protection. Wallop has supplied a range of chaff and flare cartridges to the Indian Air Force and to the Hindustan Aeronautics Ltd, Bangalore in support of product qualification. The company supports activities at various Indian ordnance factories (Pune, Jabalpur) in the development of both airborne and naval decoys.

In addition to manufacturing airborne countermeasures, Wallop designs and manufactures decoys for a wide range of both naval platforms including the KAVACH naval decoy launcher in service with the Indian Navy. Wallop also supplies chaff payloads to RWM GmbH Germany for use in their naval decoy system known as MASS. This comprises trainable decoy launcher dispensing chaff and IR decoys.
