ELECTRONIC WARFARE DIRECTORY "\ I RAF Tornado GR.l -with Marconi RWR, Bofors B missiles Laser warning receiver LWR for airborne applications covering the 0-35-1 Turn range. RPV EW systems MDS is developing EW payloads (reported to comprise high-band ESM, High/low-band ESM, communications jamming, and radar jamming systems) for RPV applications. May be associated with the British Army's Phoenix RPC programme. Sky Guardian 100 RWR currently in development. Sky Guardian 200 Processor-controlled crystal-video RWR covering the E to J radar bands, with options for C/D and K bands. Interface for a Vinten dispenser, and can co-operate with "simple" radar jammers. Sky Guardian 200 in service on RAF Buccaneer (with C/D band option), RN Sea Harrier, Austrian J35 Draken, and Spanish Navy EAV-8A, together with RAF Sea King and Puma helicopters. Sky Guardian 300 Projected radar warning/ESM system based on Sky Guardian 200, with the addition of an 1FM receiver and horn-type D/F antennas. Intended for maritime-patrol/ASW applications. Tornado radar homing & warning receiver MDS has developed a double superheterodyne RWR for RAF/Saudi Arabian Tornado F.2/3 inter ceptors. The basic modules may also form the core of warning equipment on the Tornado GR.l. Zeus Integrated internal EW suite covering the C to J radar bands. Receiver subsystem uses a multi channel superheterodyne receiver with IFM capa bility, while the active radar jamming subsystem uses Northrop transmitters. Can co-ordinate and control other on-board EW system such as LWRs and chaff/flare dispensers. Zeus is in production for the RAF Harrier GR.5/7s, and proposed for US AV-8Bs and Turkish F-16s. MEL MEL's Product Support Division is the UK design authority for the Loral EW-1017 Yellow Gate ESM system fitted to RAF Nimrod MR.2 maritime patrol aircraft and being installed on RAF's E-3D Sentry AEW aircraft. ML Wallop Defence Systems Cascade Chaff/IR-flare dispenser for helicopters. Report edly uses specially designed cartridges which acti vate well clear of the aircraft. Can be interfaced with an RWR to provide automatic or semi automatic firing. Evade Chaff/IR-flare dispenser for fixed-wing applica- dispenser outboard, and BAe ALARM anti-radar tions. Standard system reported to use four launcher units housing 41 chaff and 20 IR cartridges. Infrared decoy flares ML Wallop is a major manufacturer of IR decoy flares reported to be compatible with dispenser systems such as ALE-29, ALE-39, BOZ 107, Evade, and Masquerade. Identified rounds include the square-format Hot-Spot (HS) 1, 2 and 4 together with the round-format CM 55, HS 5, HS6 and Infrashield types. Customers thought to include the RAF, Oman, and Saudi Arabia. Masquerade Processor-controlled, podded chaff/IR-flare dispenser based on ML Aviation's CBLS 200 light bomb carrier. Uses three pre-packed launcher modules capable of housing 48 Radashield chaff and 42 Infrashield IR flare cartridges. Reported to be in production. MS Instruments Hostile Fire Indicator (HOFIN) Passive shock-wave warning system for helicop ters. Reportedly supplied to UK and Canada. Pains-Wessex Schermuly infrared decoy flares Pains-Wessex produces a range of IR decoy flares in 25x25mm and 52x52mm formats, reportedly compatible with dispensers such as the ALE-40 and the M-130. Schermuly flares are in service with the RAF and, possibly, the air forces of Denmark, Italy, and Norway. Plessey Avionics (Now part of GEC Sensors) Laser warning system Indirect/direct-illumination laser wamer for heli copters. Effective against emitters operating in the 0-5;l-3(im range. Reportedly in production. Missile approach warning (MAW) system Active pulse-Doppler radar warner to detect IR-guided missiles. Selected for RAF Harrier GR.5/7s and offered for Tornado GR.l/4s. West- inghouse markets MAW in the USA. Racal Electronics Kestrel ESM system covering the 0-6-18GHz (optional extension up to 40GHz) frequency band. Uses Racal's SADIE (Segregation, Association, Deinter- leaving, and Identification Equipment) analysis processor. Selected (under the designation Orange Reaper) for Royal Navy EH.101 ASW helicopters and supplied to Denmark to replace MIR-2 on Lynx helicopters. Kestrel also aboard the ELINT Defender prototype. MIR-2 ESM system covering the C-J radar bands. Total sales "exceed 300", applications including Royal Navy Lynx helicopters (Orange Crop) and Jetstream trainers and RAF Hercules C.IK (Orange Blossom). Updated to Mk 3 standard and Lynx which allows pulse analysis and to CW illumi nation recognition. Prophet Processor-controlled RWR covering the C-J radar bands. Suitable for both fixed-wing and helicopter applications. At least 100 systems equipping Brazilian AMX, and Middle Eastern MiG-21s. RACJAM AIR Airborne communications jamming system cover ing the 20-80MHz frequency band. Comprises the RA1796 receiver (2-l,000MHz), MA1119 signal display unit and RJS3100 (ULQ-19) 100W jamming transmitter. RACJAM AIR is thought to be in service with several customers, including the US Army on its EH-1 helicopter. Vinten Military Systems Vicon 77 Podded chaff/IR-flare dispenser. Reportedly two variants, Model 101 and 102, with maximum capacities of 308 and 384 cartridges respectively. Manual or automatic control and can be interfaced with an RWR. Vicon 78 Chaff/IR-flare dispenser for internal/external installation on fixed-wing aircraft and helicopters. Uses a common launch module holding either 32 chaff cartridges or 16 IR flares. May be interfaced with an RWR. Reportedly in production and in service on Indian Navy Sea Harriers. Widney Aish ADS-10 Dispenser for chaff, IR flares, and smoke-screening rounds for helicopter and "low-speed" fixed-wing applications. Dispenser houses four pre-loaded magazines which can be loaded with mixed stores and can interface with an RWR. UNITED STATES OF AMERICA AEL Industries AN/APR-44(V) RWR for helicopter and fixed-wing applications aimed at CW emitters. Believed available in three versions: H/I radar band APR-44(V)1, J-band APR-44(V)2, and H/I/J-band APR-44(V)3. In service with, or proposed for, the US Army and Marine Corps. Known platforms include the AH-1J/T/W, EH-1, EH-60, OH-58, OV-1D, RC-12, RU-21, RV-1D, and UH-1N. AN/ALR-67(ASR) AEL and Hughes are teamed to produce the ALR-67(ASR) "form-fit" replacement forthe USN's ALR-67 radar warning and countermeasures control system. ALR-67(ASR) is scheduled for installation on the service's A-6, AV-8B, F-14, and F-18, and uses ADA software. AIL Systems AN/ALQ-99 AIL is prime contractor on the ALQ-99 radar jamming system up to and including the ALQ-99E model. Comprising jamming (either podded or internal), receiver and control subsystems, the following variants are offered: ALQ-99A Initial production model in basic US Navy EA-6B. Reportedly effective against system-specific 44 FLIGHT INTERNATIONAL 21 October 1989
