From: megazone@wpi.WPI.EDU (MEGAZONE 23) Information: Shrike >From The Encyclopedia of World Air Power, Cresent Books, 1980. Type: air-to-surface anti-radiation missile Powerplant: one Rocketdyne Mk 39 Mod 7 or Aerojet Mk 53 solid-proplellant rocket Performance: crusing speed Mach 2 or 1,520mph (24311km/h) at sea level; maximum range at least 10 miles (16km) and possible 25 miles (40km) Weight: 390lb (177kg) Dimensions: span 3ft (91cm); length 10ft (3.05m); diameter 7.9in (20cm) Warhead: 145-lb (66-kg) fragmentation Operators: Israel, US Air Force, US Navy "The Texas Instruments AGM-45 Shrike, based partially on the Raytheon Sparrow airframe, was the first US anti-radiation missile (ARM). Development began in 1961 with the aim of countering Russian surface-to-air missiles by destroying their search and track radars. The missile entered service with the US Navy's carrier-based attack squadrons in 1964 and has also been deployed by the US Air Force. At least 13 variants have been built, each carrying a passive radiation seeker tailored to counter a different threat of combination of them. The missile's seeker locks on to the radar to be attacked, and the weapon is then fired. It can either home directly on to the enemy transmitter, or it may first climb and then dive on to its objective. This latter method allows the missile to arrive at the same time as weapons delivered by other aircraft. The US Navy uses the Shrike on its McDonnell Douglas A-4 Skyhawk, Grumman A-6 Intruder and Vought A-7 Corsair attack aircraft, but the US Air Force has a specialist Shrike-armed defence-suppression force in the form of McDonnell Douglas F-4G Wild Weasels. The F-4Gs, which are replacing Republic F-105 Thunderchiefs in the role, carry the McDonnell Douglas APR-38 radar homing and warning system to find and classify targets which are to be attacked with the Shrike and other weapons. The APR-38 uses 56 antennas spread over the aircraft to derive its information. More than 25,000 Shrikes have been built, and those in service are being up- dated to improve their performance. The missile is due to be replace eventually by the Texas Instruments HARM." >From The US War Machine, Salamander Books, 1983. Origin: Naval Weapons Center (NWC), with production by TI, USA Type: Passive homing anti-radiation missile Propulsion: Rockwell (Rocketdyne) Mk 39 or Aerojet (ATSC) MK 53 (polybutadiene) or improved Mk 78 (polyurethane, dual-thrust) solid motor Dimensions: Length 120in (3,05m); body diameter 8in (203mm); span 36in (914mm) Launch weight: (Approximately, depending on sub-type) 390lb (177kg) Range: 18 to 25 miles (29 to 40km) Flight speed: Mach 2 Warhead: Blast/frag, 145lb (66kg), proximity fuze "Based in part on the Sparrow AAM, this was the first anti-radar missile (ARM) in the US since World War 2. Originally called ARM and designated ASM-N-10, it was begun as a project at NOTS (later NWC) in 1961, and in 1962 became AGM-45A. Production by a consortium headed by Texas Instruments (TI) and Sperry Rand/ Univac began in 1963 and Shrike was in use in SE Asia three years later with Wild Weasel F-105Gs and EA-6As. Early experience was disappointing and there have since been numerous models, identified by suffix numbers, to rectify faults or tailor the passive homing head to a new frequency band identified in the potential hostile inventory. Carried by the US Navy/Marines A-4, A-6, A-7 and F-4, the Air Force F-4, F-105 and EF-111 and the Israeli F-4 and Kfir, Shrike is switched on while flying towardsthe target and is fired as soon as the TI radiation seeker has locked-on. After motor cutoff Shrike flies a bal- listic path until control system activation. The seeker has a monopulse crystal video receiver and continually updates the guidance by determining the direction or arrival of the hostile radiation, homing the missile into the enemy radar with its cruciform centre-body wings driven in "bang/bang" fashion by a hot-gas system. There were at least 18 sub-types in the AGM-45-1 to -10 families, with over 13 different tailored seeker heads, of which the USAF bought 12,863 by 1978 and the Navy a further 6,200. In the Yom Kippur war Israel used Shrike tuned to 2965/2900 MHz and 3025/3050 MHz to defeat SA-2 and SA-3, but was helpless against SA-6. In 1978-81 additional procurement centred on the -9 and -10 for the USAF to be carried by F-4G and EF-111A platforms, together with modification kits to euip existing rounds to home on to later SAM and other radars." ############################################################################### # "Calling Garland operator 7G," EVE Email megazone@wpi.wpi.edu # # MEGAZONE, aka DAYTONA, aka BRIAN BIKOWICZ Bitnet Use a gateway.
