TheAdvanced Short Range Air-to-Air Missile(ASRAAM), also known by its United States designationAIM-132,is an imaginginfrared homingair-to-air missile,produced byMBDA UK,that is designed for close-range combat. It is in service in theRoyal Air Force(RAF), replacing theAIM-9 Sidewinder.The ASRAAM is designed to allow the pilot to fire and then turn away before the opposing aircraft can close for a shot. It flies at over Mach 3 to ranges in excess of 25 kilometres (16 mi).[3]It retains a 50 g maneuverability provided by body lift and tail control.[7][1]

The project started as a British-German collaboration in the 1980s. It was part of a wider agreement in which the US would develop theAIM-120 AMRAAMfor medium-range use, while the ASRAAM would replace the Sidewinder with a design that would cover the great range disparity between the Sidewinder and the AMRAAM. Germany left the programme in 1989. The British proceeded on their own and the missile was introduced into RAF service in 1998. It is being introduced to theIndian Air Force,theQatar Air Forceand theRoyal Air Force of Oman,and formerly saw service in theRoyal Australian Air Force.

The ASRAAM is also the base design for theCommon Anti-Aircraft Modular Missile(CAMM) used by the British Army, Royal Navy and several allied forces in the surface-launched role. A surface-launched variant of the ASRAAM itself has been improvised for theArmed Forces of Ukraine.

History

[edit]

In the 1980s,NATOcountries signed aMemorandum of Agreementthat the United States would develop the AIM-120 Advanced Medium-Range Air-to-Air Missile (AMRAAM), while a primarily British and German team would develop a short-range air-to-air missile to replace the Sidewinder. The team included the UK (Hawker Siddeley, by this point known as BAe Dynamics) and Germany (Bodensee Gerätetechnik) sharing 42.5 per cent of the effort each, Canada at 10 per cent and Norway at 5 per cent. The US assigned this missile the name AIM-132 ASRAAM.[8]

New ASRAAM

[edit]

The rapid decline and eventual fall of theSoviet Unionin the late 1980s led to considerably less interest in the ASRAAM. By February 1988 the US was already agitating for changes. In July 1989 the Germans exited the programme effectively ending the agreement. Various reasons are often cited including the ending of the Cold War and full realisation of the capabilities of the RussianR-73 missile,but many commentators think this was a smokescreen for financial and defence industrial share issues.[9]

This left Britain in charge of the project and they began redefining it purely to RAF needs, sending out tenders for the new design in August 1989. This led to the selection of a new Hughesfocal plane arrayimaging array seeker instead of the more conventional design previously used, dramatically improving performance and countermeasure resistance. A UK contest in 1990 examined the new ASRAAM, the FrenchMICAand a new design from Bodensee Gerätetechnik, their version of the ASRAAM tuned for German needs. In 1992 the Ministry of Defence announced that ASRAAM had won the contest, and production began in March that year. The German design, by now part ofDiehl BGT Defence,became theIRIS-T.[8]

While ASRAAM was entering production, momentum behind US-led industrial and political lobbying grew significantly and, combined with the strengthening European economy, forced the US government to conclude testing in June 1996 and move away from the ASRAAM program.[10]

UK development and manufacture went ahead and the first ASRAAM was delivered to the Royal Air Force (RAF) in late 1998. It equips the RAF'sTyphoon.It was also used by the RAF'sHarrier GR7andTornado GR4forces until their retirement. In February 1998 ASRAAM was selected by the Royal Australian Air Force (RAAF) for use on theirF/A-18 Hornetsfollowing competitive evaluation of the improved ASRAAM, the RafaelPython 4and the AIM-9X,[8]and entered RAAF service in August 2004.[11]In March 2009 the RAAF successfully carried out the first in-service "Lock-on after launch"firing of an ASRAAM at a target located behind the wing-line of the" shooter "aircraft.[12]

Characteristics

[edit]

ASRAAM is a high speed, extremely manoeuvrable, heat-seeking, air-to-air missile. Built by MBDA UK, it is designed as a "fire-and-forget" missile.[9]ASRAAM is intended to detect and launch against targets at much longer ranges, as far as early versions of the AMRAAM, in order to shoot down the enemy long before it closes enough to be able to fire its own weapons. In this respect the ASRAAM shares more in common with the AMRAAM than other IR missiles, although it retains high manoeuvrability. To provide the needed power, the ASRAAM is built on a 16.51 cm (6½ inch) diameter rocket motor compared with Sidewinder's (AIM-9M and X) and IRIS-T's 12.7 cm (5-inch) motors (which trace their history to the 1950s unguidedZuni rocket). This gives the ASRAAM significantly more thrust and therefore increased speed and range up to 50 kilometres (31 mi).[4]

The main improvement is a new 128×128 resolutionimaging infraredfocal plane array(FPA) seeker manufactured byHughesbefore they were acquired byRaytheon.This seeker has a long acquisition range, high countermeasures resistance, approximately 90-degree off-boresight lock-on capability, and the possibility to designate specific parts of the targeted aircraft (like cockpit, engines, etc.).[13]The ASRAAM also has a LOAL (Lock-on after launch) ability which is a distinct advantage when the missile is carried in an internal bay such as in theF-35 Lightning II.However in 2012 the requirement for ASRAAM internal carriage on the F-35 was dropped, and the aircraft now uses external carriage only.[14]The ASRAAM warhead is triggered either by laser proximity fuse or impact. A laser proximity fuse was selected because RF fuses are vulnerable to EW intervention from enemy jammers.[15]The increased diameter of ASRAAM also provides space for increased computing power, and so improved counter counter-measure capabilities compared with other dogfighting missiles such as AIM-9X.[citation needed]

Developments

[edit]

On 8 July 2014,Indian Ministry of Defencesigned a £250m ($428m) contract with MBDA to purchase 384 ASRAAM short range air-to-air missile to equip itsSEPECAT/HAL Jaguarstrike aircraft fleet and replace the ageingMatra Magic R550.MBDA's offering overcame competition from competitors including Rafael's Python-5 missile, emerging as the winner in 2012. This built on an existing 2012 order for 493MICAmissiles to replaceMatra S-530DandMagic IImissiles as part of an Indian Air ForceMirage 2000upgrade.[16][17]

In September 2015, the UK's MoD signed a £300 million contract for a new and improved version of the ASRAAM that would leverage new technological developments, including those from the CAMM missile. This variant would replace the current one when it goes out of service in 2022. A further £184 million contract was awarded in August 2016 to provide additional stocks of the new ASRAAM for the UK's F-35B. This new variant will be operationally ready on the Eurofighter Typhoon in 2018 and on the UK's F-35Bs from 2022 onwards.[5][18][19][needs update]

In February 2017, successful firing of ASRAAMs from F-35 Lightning IIs were conducted at Naval Air Station Patuxent River and Edwards Air Force Base in the USA. This represented the first time that a British-designed missile had been fired from an F-35 JSF and the first time any non-US missile had ever been fired from the aircraft.[20]

As of 31 January 2019, theIndian Air Forceis testing the compatibility of the ASRAAM weapons system with theSukhoiSu-30MKI,and aims to make the ASRAAM its standardised short range missile across multiple aircraft types, including theTejas.Final testing and operational clearance are to be achieved by the end of 2019.[21]Bharat Dynamics Limitedwill produce the missile at itsBhanoorunit. The facility will also offer maintenance, repair and overhaul services.[22]

Variants

[edit]

ASRAAM P3I

[edit]

In 1995,HughesandBritish Aerospacecollaborated on the "P3I ASRAAM", a version of ASRAAM as a candidate for the AIM-9X program.[citation needed]The ultimate winner was the Hughes submission using the same seeker but with the rocket motor, fuse and warhead of the AIM-9M. The latter was a US Air Force stipulation to ease the logistics burden and save money by reusing as much as possible of the existing AIM-9 Sidewinder, of which 20,000 remained in the US inventory.[citation needed]

ASRAAM Block 6

[edit]

ASRAAM Block 6 standard, developed under the ASRAAM Sustainment programme, entered service on the Typhoon in April 2022,[23]and will enter F-35 service in 2024. The Block 6 introduces new and updated sub-systems, and replaces external cooling with a new internal cooler. The original Raytheon seeker has been replaced with a newUK-built seeker of higher resolution. There are no US-made components, meaning that it does not come underITARrestrictions and can therefore be exported without US approval.[24][25]

Common Anti-Air Modular Missile (CAMM)

[edit]
Main article:CAMM (missile family)

At theDSEiconference in September 2007 it was announced that the UK MoD was funding a study byMBDAto investigate a replacement for theRapierandSea Wolfmissiles for theRoyal NavyandBritish Armyrespectively. The Common Anti-Air Modular Missile (CAMM) would share components with ASRAAM, such as the very low signature rocket motor from Roxel and the warhead and proximity fuze from Thales but with updated electronics, an activeRF seekerand data link so allowing for mid-course corrections from suitably-equipped land or even air platforms.[26][27]CAMM began entering service in 2018 and has since be sold to nine other nations for both land and naval use. It has since become a family of weapons with a number of additional missile variants on order or in development.

Armed Forces of Ukraine (Surface-launched ASRAAM)

[edit]

In August 2023 it emerged that Ukraine had been provided an unknown number of improvised ground-based launch platforms for ASRAAM. Developed in four months by a joint MBDA and MoD team, It has been used by theArmed Forces of Ukraineto provide short range air defence (SHORAD) against Russian aerial threats such as helicopters, cruise missiles and drones such as theHESA Shahed 136.Images of the system appear to show a twin-launcher mounted on the back of aSupacat6x6 vehicle, allowing it to remain mobile, whilst guidance can be provided by a Hawkeyeelectro-opticalsuite. The missile has a "fire and forget" capacity. Reportedly, the system has achieved a 90% success rate during operations. This system is not to be confused with the dedicated surface-launched development of ASRAAM, CAMM/Sky Sabreair defence system.[29][14][30][31]On 7 May 2024 footage was published showing the first confirmed loss of a Ukrainian ASRAAM Supacat based launcher which was destroyed by aZALA Lancet.[32][33]
