Bolt from a more distant blue: between the two extremes of low-cost guided bombs (see Armada 1/2002) and expensive long-range cruise missiles (3/2001) there exists a need for cost-effective tactical air-to-ground guided weapons that can deliver suitable warheads precisely and from a safe distance against high-value, hardened, mobile or multiple targets by day and night and under all weather conditions. (Airborne Warfare).
Even when released from high altitude Conventionally, an altitude above 10,000 meters (33,000 feet). See also altitude. , simple ballistic ordnance has a forward throw of less than ten kilometres, and similar distances may be achieved in loft manoeuvres from low altitude. Such figures are clearly inadequate for attacks against ground targets that have modern Short-range Air Defence (Shorad) systems. Achieving longer air-to-ground ranges depends on giving the weapon better aerodynamics aerodynamics, study of gases in motion. As the principal application of aerodynamics is the design of aircraft, air is the gas with which the science is most concerned. or some means of propulsion, or a combination of the two. The following discussion relates to those missiles that provide a range substantially greater than ten kilometres, but do not employ turbine engines, which are associated with ranges well in excess of 100 kilometres and for present purposes are excluded as cruise missiles.
Conceptually, the first step in keeping the attacking aircraft outside the range of Shorad systems is to give the warhead fixed wings, a simple guidance system and control surfaces. However, wingspan is then restricted by the proximity of other stores, and lift:drag ratio is limited accordingly. Eads/LFK was a leader in this field, first exploiting the lifting body lift·ing body

The current production standard is the Improved SFW, which almost doubles the footprint area of the baseline model. The US Air Force plans to acquire a total of 5000 units, over half of which have so far been ordered. The Textron Systems BLU-108 is also produced for the Raytheon AGM-154B (discussed later).
Aside from the CBU-87/B CEM, Kosovo also witnessed the use of the TMD-based CBU-102(V)2/B, which dispensed BLU-114 submunitions filled with highly conductive carbon-fibre threads to short-circuit Yugoslav electrical grids. At that stage the dispenser was unguided, and had to be released from an F-117 flying below 10,000 feet. Another TMD variant is being developed to dispense flechettes in attacks on targets such as chemical and biological storage facilities. It is envisaged that the TMD series will later be used to dispense the US Army's wide area anti-armour mines, anti-helicopter mines and other future smart submunitions.
In the interim, the US Air Force plans to have 40,000 TMDs (including the CBU-102 series) fitted with the Lockheed Martin Wind-Corrected Munitions Dispenser (WCMD WCMD Wind-Corrected Munitions Dispenser
WCMD Welsh College of Music and Drama (institution of higher education in Cardiff, Wales, UK) , pronounced "Wick-Mid") tail kit, which employs inertial navigation to steer the munition from a GPS-derived release point to precise target co-ordinates, compensating for wind and adverse weather. This programme stems from experience in the 1991 Gulf War, when the US Air Force was forced by Iraqi air defences to release ordinance from medium/high altitude, with significant loss of precision. Lockheed Martin publicity material refers to an accuracy of 25 metres, but reports indicate that in tests the WCMD has achieved accuracy better than ten metres. The system reached initial operational capability on the B-52 in late 1998. Lacking a GPS receiver and a seeker for terminal guidance, the WCMD is intentionally a low-cost kit, with a unit price currently below $9000. The CEM+WCMD combination first saw operational use in Afghanistan in late 2001.
The discussion has so far been concerned with the results that can be achieved by adding variable-geometry wing kits to standard bombs and dispensers. This approach, exemplified by the Diamond Back and the LongShot, is clearly attractive in budgetary terms, since it makes full use of ordnance that is already in the inventory. However, in principle longer ranges can be achieved by designing a brand-new guided missile, containing a warhead or submunitions from existing ordnance, but without the aerodynamic constraints of an add-on wing kit.
This principle was adapted for the Kentron (Denel) Raptor 1, which was used operationally by the South African Air Force The South African Air Force (SAAF) (Afrikaans: Suid-Afrikaanse Lugmag) is the air force of South Africa. It is the world's second oldest independent air force, and its motto is Per Aspera Ad Astra (Through adversity to the stars). in the 1980s war in Angola, but unveiled for the first time to the public during the African Aerospace exhibition in 1998. It carried a standard 550 kg fragmentation or penetration warhead and had a TV camera in the nose for terminal guidance. Launched from a Mirage F1 at 35,000 feet, its high aspect ratio wing gave the Raptor 1 a range of 60 kilometres. This suggests a rather disappointing lift:drag ratio of 5.6:1, but the true figure may be somewhat better, as the Raptor normally makes a steep dive in the terminal phase. Kentron has subsequently marketed the missile with GPS navigation and an optional imaging-infrared seeker for night operation. Pilots reported to Armada that under certain dusk conditions, strong sun reflections from rivers (when attacking a bridge, for example) could blind the camera and therefore disrupt target tracking. A dedicated anti-radiation version has been mentioned, but there appear to be no reports of export orders. One reason may be that its launch weight of 980 kg makes it unsuitable for lightweight fighters. In the case of an aircraft such as the Mirage F1, the Raptor and its datalink pod take the inboard Built in. Inboard devices are built into the main unit. Contrast with outboard. See onboard. wing pylons, restricting the carriage of external tanks. A Raptor II was put into production in 1998.
The Raytheon AGM-154 Joint Stand-Off Weapon (Jsow) is aerodynamically a very clean weapon and probably represents the practical limit for glide performance. It began as a US Navy development, aimed at replacing missiles such as the Maverick, Walleye walleye, in medicine
walleye: see strabismus.
walleye, in zoology
walleye or walleyed pike: see perch. , Skipper, the Rockeye cluster bomb and older laser-guided bombs. The Navy requirement placed a weight restriction of 485 kg on the Jsow so that an AV-8B could land vertically with a missile under one wing. However, it is envisaged that with different warheads the weight will grow to around 680 kg. The Jsow attains a range of 24 kilometres from low-level release and 64 kilometres from high release. On published data, the Jsow appears to have a lift:drag ratio of around 7:1.
In 1991, Texas Instruments (since part of Raytheon) was selected to develop the missile, and in the following year the US Air Force joined the programme, which thus became Jsow. It is currently conceived in three principal forms. The baseline AGM-154A employs GPS+INS navigation and dispenses 145 BLU-97 CEBs, reduced from 202 in the case of the CEM. Deliveries began in 1998, and in the following year this first version of the Jsow was used operationally from US Navy F/A-18s against targets such as air defence radars, armour, artillery and personnel in Kosovo. The AGM-154A was also used in early 2001 against Iraqi radar sites, but produced larger than expected miss distances.
The AGM-154B is still under development. It will employ the same guidance as the -154A, but will dispense six BLU-108s, compared to ten in the case of the SFW. The AGM-154C will have an imaging infrared seeker for terminal guidance and a 225 kg class penetration warhead, either the BLU-111 or the RO Defence Broach. It may be noted that a version of the Jsow with a turbine engine was proposed to meet an Australian requirement (Air 5418), recalling that an AGM-154 with a Williams W-24-8 turbojet turbojet: see turbine.

The use of rocket motors makes it possible to achieve air-to-ground ranges in the order of 100 kilometres. The point may be illustrated by the case of the rocket-powered Boeing (formerly Rockwell) AGM-130, which provides roughly three times the maximum range of the GBU-15 glide bomb (or Cruciform cruciform /cru·ci·form/ (kroo´si-form) cross-shaped.
cross-shaped. Wing Weapon) on which it is based. The GBU-15 is available in two versions: the GBU-15(V)1/B with a television camera for terminal guidance, and the -15(V)2/B with an imaging infrared seeker for night operations. Either kit can be fitted to the Mk 84 bomb body or the BLU-109/B penetrator. It was planned to have a submunition version based on the SUU-54 dispenser, but this never eventuated. Development began in 1974, and Rockwell produced over 3000 kits. The US Air Force is currently believed to have around 1500, most of which are to be equipped with Raytheon GPS guidance systems, giving an accuracy of better than five metres without use of the seeker. The GBU-15 has a range of around 30 kilometres from high altitude release. This suggests a lift:drag ratio of 3.3:1, which appears reasonable in view of its small aerofoil aer·o·foil

Development of the rocket-powered Boeing AGM-130 began in 1984, the AGM-130A having the Mk 84 warhead, and the AGM-130C the BLU-109/B penetrator. The operator can set the altitude-hold system to give cruise heights between 1000 and 2000 feet, reducing in the terminal phase to as low as 200 feet. It has a range of 28 kilometres from low-level release, and up to 74 kilometres from high altitude. During the 1991 Gulf War the US Air Force fired 71 AGM-130s from F-15Es and F-111Fs. At the start of Operation Allied Force in Kosovo, US stocks had reduced to around 200, of which half were fired from F-15Es during that conflict. However, 400 more were subsequently ordered. It should be noted that, with launch weights of 1140 and 1323 kg respectively, both the GBU-15 and AGM-130 require a large platform such as the F-4 or F-15.
The US Air Force's other principal missile in this category is the much lighter Raytheon AGM-65 Maverick. Deliveries began in 1972 and it has been used by 30 armed services The Constitution authorizes Congress to raise, support, and regulate armed services for the national defense. The President of the United States is commander in chief of all the branches of the services and has ultimate control over most military matters. , including the US Navy and US Marine Corps. More than 66,000 have been built. The Maverick has been produced with three types of guidance: television lock-on for the AGM-65A/B/H, imaging infrared for the AGM-65D/F/G, and laser spot-homing for the AGM-65E. There are two warhead options: the 57-kg shaped charge for the AGM-65A/B/D/H, and the 136-kg penetration/blast warhead for the AGM-65E/F/G/H/K (see below).
With a launch weight of only 210 to 307 kg (depending on the warhead and guidance system), the AGM-65 can be fitted to a very broad spectrum of aircraft. Maximum range is 10 to 14 kilometres from a hovering helicopter, increasing to 24 kilometres from a high level release.
The Maverick airframe is no longer manufactured, but US Air Force AGM-65Gs are being fitted with charge-coupled device seekers to produce AGM-65Ks with improved dusk/dawn capability, while their old imaging infrared seekers are now fitted to stored AGM-65As for export customers. More than 5300 Mavericks were fired in the course of Desert Storm, with a 93 per cent success rate. As a result of experience in Kosovo, where Britain lacked an air-to-ground missile suitable for attacks under low cloud, the Royal Air Force is buying the AGM-65G2 with special anti-armour software.
For longer ranges, the US Navy's next step beyond the AGM-65 is the Boeing AGM-84E Slam (Stand-off Land Attack Missile), which has INS+GPS mid-course navigation and TV guidance in the terminal phase. However, its Teledyne Continental J402 turbojet engine provides a range of more than 100 kilometres, taking it outside the scope of this present discussion. The AGM-84H Slam-ER with variable sweep wings is capable of around 300 kilometres, making it a true cruise missile.
Future US possibilities include the Northrop Grumman Miniature Autonomous Attack Weapon, Long Range, which places the warhead and acoustic sensors from the company's Bat submunition in the airframe of the Miniature Air-Launched Decoy DECOY.

The lighter version is suitable for operation on aircraft such as the Hawk and F-5. The PGM has a maximum range of 15 kilometres from low-level release, 30 kilometres from medium levels, and up to 50 kilometres from high altitude.
The Kentron Raptor II is a rocket-powered derivative of the battle-proven TV-guided Raptor I glide bomb, with a launch weight of 1200 kg. The Somchem (from the Denel Group) twin rocket motor pod is fixed under the fuselage of the Raptor I and is jettisoned after around 60 kilometres; the missile then glides to a maximum distance of 120 kilometres from release. Terminal accuracy is approximately three metres. The missile, in production since 1998, has been integrated on the Mirage III and F1, the Cheetah and the Su-24 (Fencer).
The Rafael Popeye was developed to provide a stand-off attack capability and as a reaction to Israeli aircraft losses during the 1982 invasion of Lebanon. This rocket-powered missile with inertial mid-course guidance entered service in the late 1980s and was adopted by the US Air Force as a means to give the B-52H a precision strike capability. Lockheed Martin was selected to partner Rafael and the two companies jointly established Precision Guided Systems US in Alabama to produce the Popeye as the AGM-142 Havenap. The AGM-142A, or Popeye 1, carries a 340 kg blast-fragmentation warhead and is fitted with a TV/CCD seeker, providing man-in-the-loop guidance for the terminal phase. It has a launch weight of approximately 1360 kg and a range of around 90 kilometres. The AGM-142C and -142D are reported to have imaging infrared seekers and two different 360 kg-class penetration warheads. The AGM-142E has an improved imaging infrared seeker (sometimes referred to as the Z-seeker) with a selectable field of view.
Following deliveries to Israel and the United States (the US Air Force has had over 200 rounds), the AGM-142 series was exported to Australia, Greece, South Korea and Turkey (110 rounds). For political reasons (it being a semi-Israeli missile), the AGM-142 was not employed during the 1991 Gulf War. Two were fired from a B-52H during Operation Allied Force over Kosovo, but they evidently suffered a software problem.
The AGM-142B Havelite or Popeye 2 is a lightened derivative with a shorter rocket motor and TV guidance. It has a launch weight of 1125 kg to make it suitable for smaller aircraft such as the F-16, but maximum range is unchanged. In 1997 Israel and Turkey reached an agreement to jointly produce the Popeye 2. There were reports that the missile was to be supplied to India, but America is thought to have pressured Israel not to proceed with the sale.

Adv. 1. inspired by America's Bullpup, Russia's Zvezda-Strela Kh-23 (AS-7) is a 280 kg radio-controlled missile with a nominal range of ten kilometres. This old (1973) weapon was designed for use from the MiG-23 and was exported to more than 30 countries. The Zvezda-Strela Kh-25M (AS-10) is a stretched and slightly heavier derivative, mainly built in the form of the command-guided Kh-25MR and the laser-homing Kh-25ML.
Aside from anti-radiation missiles (of which the Russian Air Force The Russian Air Force (Russian: Военно-воздушные cилы России, transliteration: Voyenno-vozdushnye sily Rossii has used many types), the only other Russian tactical air-to-ground missile is the Vympel Kh-29 (AS-14), which appeared somewhat later (1980) and is a much heavier (660 kg) device. The extended-range Kh-29TE version, marketed from 1997, has a range of 17 to 32 kilometres, depending on launch height. The Kh-29 delivers a 320 kg high explosive, penetration warhead, which is designed for attacks on ships of up to 10,000 tonnes, reinforced concrete shelters, runways, large bridges and industrial buildings. It is marketed in three principal forms: the TV-guided Kh-29T series, the laser-spot homing Kh-29L and the infrared-guided Kh-29D.
The class-leader in anti-radiation missiles is the Raytheon AGM-88 Harm (High-speed Anti-Radiation Missile) a 360 kg supersonic weapon that first appeared in 1984 and first saw active service in 1986 over Libya. Approximately 20,000 have been manufactured and 2041 fired in Desert Storm. Maximum range is in excess of 105 km. The missile has been exported to Australia, Germany, Greece, Italy, South Korea, Spain and Turkey. It is planned that the Harm will be replaced by the Advanced Anti-Radiation Guided Missile, based on the AGM-88, with airframe improvements, multi-mode guidance and ultimately a new propulsion system, possibly a ducted rocket.
The 265 kg MBDA Alarm (Air-Launched Anti-Radar Missile) is now in service on British and Saudi Tornadoes. It provides a choice of five operating modes, including one in which it climbs and then loiters under a parachute, scanning for emitters.
Russia has a large array of anti-radiation missiles, starting with the 320 kg Zvezda-Strela Kh-25MP and -25PS (AS-12) variants of the Kh-25 discussed earlier. The company markets the Kh-25MPU See microprocessor. (distinguished by a second set of canards) with a range of up to 40 kilometres.
The 715 kg Raduga Kh-28 (AS-9) was the first Russian missile designed from the outset for the anti-radar role. It has a liquid propellant rocket and a range of up to 85 kilometres.
