The Advanced Short Range Air-to-Air Missile (ASRAAM), also known by its United States designation AIM-132, is an imaging infrared homing air-to-air missile, produced by MBDA UK, that is designed for close-range combat. It is in service in the Royal Air Force (RAF), replacing the AIM-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 the AIM-120 AMRAAM for 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 the Indian Air Force, the Qatar Air Force and the Royal Air Force of Oman, and formerly saw service in the Royal Australian Air Force.
The ASRAAM is also the base design for the Common 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 the Armed Forces of Ukraine.
In the 1980s, NATO countries signed a Memorandum of Agreement that 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]
The rapid decline and eventual fall of the Soviet Union in 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 Russian R-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 Hughes focal plane array imaging 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 French MICA and 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 of Diehl BGT Defence, became the IRIS-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's Typhoon. It was also used by the RAF's Harrier GR7 and Tornado GR4 forces until their retirement. In February 1998 ASRAAM was selected by the Royal Australian Air Force (RAAF) for use on their F/A-18 Hornets following competitive evaluation of the improved ASRAAM, the Rafael Python 4 and 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]
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 unguided Zuni 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 resolution imaging infrared focal plane array (FPA) seeker manufactured by Hughes before they were acquired by Raytheon. 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 the F-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 ]
In 2014, India's defence ministry signed a £250m ($428m) contract with MBDA to equip its SEPECAT/Hindustan Aeronautics Jaguar strike aircraft with the company's ASRAAM short range air-to-air missile. 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 493 MICA missiles to replace Matra S-530D and Magic II missiles as part of an Indian Air Force Mirage 2000 upgrade. [16]
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] [17] [18] [ 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. [19]
As of 31 January 2019 the Indian Air Force is testing the compatibility of the ASRAAM weapons system with the Sukhoi Su-30MKI, and aims to make the ASRAAM its standardised short range missile across multiple aircraft types, including the Tejas. Final testing and operational clearance are to be achieved by the end of 2019. [20] Bharat Dynamics Limited will produce the missile at its Bhanoor unit. The facility will also offer maintenance, repair and overhaul services. [21]
In 1995, Hughes and British Aerospace collaborated 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 standard, developed under the ASRAAM Sustainment programme, entered service on the Typhoon in April 2022, [22] 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 new UK-built seeker of higher resolution. There are no US-made components, meaning that it does not come under ITAR restrictions and can therefore be exported without US approval. [23] [24]
At the DSEi conference in September 2007 it was announced that the UK MoD was funding a study by MBDA to investigate a replacement for the Rapier and Sea Wolf missiles for the Royal Navy and British Army respectively. 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 active RF seeker and data link so allowing for mid-course corrections from suitably-equipped land or even air platforms. [25] [26] 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.
On 14 December 2021 a RAF Typhoon operating against Islamic State in southern Syria shot down a hostile drone with an ASRAAM missile. This was the first time the British military had shot down an enemy aircraft since the Falklands War. [27]
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 the Armed Forces of Ukraine to provide short range air defence (SHORAD) against Russian aerial threats such as helicopters, cruise missiles and drones such as the HESA Shahed 136. Images of the system appear to show a twin-launcher mounted on the back of a Supacat 6x6 vehicle, allowing it to remain mobile, whilst guidance can be provided by a Hawkeye electro-optical suite. 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 Sabre air defence system. [28] [14] [29] [30] On 7 May 2024 footage was published showing the first confirmed loss of a Ukrainian ASRAAM Supacat based launcher which was destroyed by a ZALA Lancet. [31] [32]
Royal Air Force / Fleet Air Arm - Equips the Typhoon and F-35B Lightning in RAF and Royal Navy service.
Indian Air Force - on 8 July 2014 India signed a deal to procure 384 ASRAAMs from MBDA UK to replace the aging Matra Magic R550, to be integrated onto the SEPECAT Jaguar strike aircraft. [33]
Armed Forces of Ukraine - In August 2023 a surface-launched version of ASRAAM was reported mounted on a Supacat HMT chassis in Ukraine. [28] [14] [29]
Royal Australian Air Force - Equipped the F/A-18A/B Hornet from 2004 until the aircraft's retirement in 2021. The RAAF uses the AIM-9X with the F/A-18F, EA-18G and F-35A. [34]
The AIM-120 Advanced Medium-Range Air-to-Air Missile(AMRAAM) ( AM-ram) is an American beyond-visual-range air-to-air missile capable of all-weather day-and-night operations. It uses active transmit-receive radar guidance instead of semi-active receive-only radar guidance. When an AMRAAM missile is launched, NATO pilots use the brevity code "Fox Three".
The Eurofighter Typhoon is a European multinational twin-engine, supersonic, canard delta wing, multirole fighter. The Typhoon was designed originally as an air-superiority fighter and is manufactured by a consortium of Airbus, BAE Systems and Leonardo that conducts the majority of the project through a joint holding company, Eurofighter Jagdflugzeug GmbH. The NATO Eurofighter and Tornado Management Agency, representing the UK, Germany, Italy and Spain, manages the project and is the prime customer.
The Panavia Tornado Air Defence Variant (ADV) is a long-range, twin-engine swing-wing interceptor aircraft developed by the European Panavia Aircraft GmbH consortium. It was a specialised derivative of the multirole Panavia Tornado.
The Meteor is a European active radar guided beyond-visual-range air-to-air missile (BVRAAM) developed and manufactured by MBDA. It offers a multi-shot capability, and has the ability to engage highly maneuverable targets such as jet aircraft, and small targets such as UAVs and cruise missiles in a heavy electronic countermeasures (ECM) environment with a range far in excess of 200 kilometres (110 nmi).
The Storm Shadow is a Franco-British low-observable, long-range air-launched cruise missile developed since 1994 by Matra and British Aerospace, and now manufactured by MBDA. "Storm Shadow" is the weapon's British name; in France it is called SCALP-EG. The missile is based on the French-developed Apache anti-runway cruise missile, but differs in that it carries a unitary warhead instead of cluster munitions.
The IRIS-T is a medium range infrared homing missile available in air-to-air and surface-to-air variants. It also is called AIM-2000.
An air-to-air missile (AAM) is a missile fired from an aircraft for the purpose of destroying another aircraft. AAMs are typically powered by one or more rocket motors, usually solid fueled but sometimes liquid fueled. Ramjet engines, as used on the Meteor, are emerging as propulsion that will enable future medium- to long-range missiles to maintain higher average speed across their engagement envelope.
The MICA is a French anti-air multi-target, all weather, fire-and-forget short and medium-range missile system manufactured by MBDA France. Its name is an abbreviation of Missile d'Interception, de Combat et d'Auto-défense. It is intended for use both by air platforms as individual missiles as well as ground units and ships, which can be equipped with the rapid fire MICA Vertical Launch System. It is fitted with a thrust vector control (TVC) system. It was developed from 1982 onward by Matra. The first trials occurred in 1991, and the missile was commissioned in 1996 to equip the Rafale and Mirage 2000. It is a replacement for both the Super 530 in the interception role and the Magic II in the dogfighting role.
Brimstone is a ground or air-launched ground attack missile developed by MBDA UK for the UK's Royal Air Force. It was originally intended for "fire-and-forget" use against mass formations of enemy armour, using a millimetre wave (mmW) active radar homing seeker to ensure accuracy even against moving targets. Experience in Afghanistan led to the addition of laser guidance in the dual-mode Brimstone missile, allowing a "spotter" to pick out specific and the highest priority targets, particularly useful to minimise collateral damage when friendly forces or civilians were in the area. The tandem shaped-charge warhead is much more effective against modern tanks than older similar weapons such as the AGM-65G Maverick missile. Three Brimstones are carried on a launcher that occupies a single weapon station, allowing a single aircraft to carry many missiles.
The Skyflash, or Sky Flash in marketing material, was a medium-range semi-active radar homing air-to-air missile derived from the US AIM-7 Sparrow missile and carried by Royal Air Force McDonnell Douglas F-4 Phantoms and Tornado F3s, Italian Aeronautica Militare and Royal Saudi Air Force Tornados and Swedish Flygvapnet Saab Viggens.
NASAMS is a distributed and networked short- to medium-range ground-based air defense system developed by Kongsberg Defence & Aerospace (KDA) and Raytheon. The system defends against unmanned aerial vehicles (UAVs), helicopters, cruise missiles, unmanned combat aerial vehicles (UCAVs), and fixed wing aircraft, firing any of a wide range of existing missiles.
The Air Combat Evaluation (ACEVAL) and the Air Intercept Missile Evaluation (AIMVAL) were two back-to-back Joint Test & Evaluations chartered by the United States Department of Defense that ran from 1974-78 at Nellis Air Force Base in Nevada. Both the U.S. Air Force and U.S. Navy participated, contributing a team of F-15 Eagle and F-14 Tomcat fighter aircraft and using the local F-5E Aggressor aircraft as the Red Force. The fundamental question that needed to be answered was one of "quantity vs quality". Mock engagements showed that cheaper, lower-technology fighters armed with all-aspect missiles were able to destroy the more advanced, expensive F-15's and F-14's. These results of the AIMVAL/ACEVAL testing led to the Air Force decision to structure its fighter forces with a balance of cheaper F-16's along with the more expensive F-15's, and the Navy took a similar strategy in procuring cheaper F/A-18's along with the more expensive F-14's. The results had other impacts as well, such as decisions regarding missile development.
The planning for the future of the Royal Air Force involves supporting ongoing British military operations and the introduction of new aircraft types including unmanned aerial vehicles and the BAE Systems Tempest sixth-generation fighter in the 2030s. Priorities include greater focus on network enabled capability and mixing crewed fighter jets with UAVs and swarming drones. The new initiative will focus on increasing interoperability with members of NATO and becoming carbon net-zero, with strategies such as using sustainable aviation fuels in aircraft.
The CAMM is a family of surface-to-air missiles developed by MBDA UK for the United Kingdom. CAMM is derived from, and shares some common features and components with, the Advanced Short-Range Air-to-Air Missile (ASRAAM), but with updated electronics, a soft vertical launch system, and an active radar homing seeker. The CAMM family is either currently in-use or has been ordered by ten nations.
The AIM-9 Sidewinder is a short-range air-to-air missile. Entering service with the United States Navy in 1956 and the Air Force in 1964, the AIM-9 is one of the oldest, cheapest, and most successful air-to-air missiles. Its latest variants remain standard equipment in most Western-aligned air forces. The Soviet K-13, a reverse-engineered copy of the AIM-9B, was also widely adopted.
The SLAMRAAM (Surface Launched AMRAAM) was the United States Army program to develop a Humvee-based surface-to-air missile launcher for the AIM-120 AMRAAM missile, manufactured by Raytheon Technologies and Kongsberg Defence & Aerospace. Surface-launched AMRAAM missile was first used in Kongsberg's NASAMS air defense system, fielded in 1995.
The British Aerospace Hawk 200 is a single-seat, single engine light multirole fighter designed for air defence, air denial, anti-shipping, interdiction, close air support, and ground attack.
SPEAR is a family of air-launched effectors under development by MBDA UK for the Royal Air Force's Select Precision Effects At Range (SPEAR) Capability 3, or SPEAR 3 programme, from which the system also derives its name. The SPEAR family currently consists of two variants: Spear, a 100kg class air-to-surface cruise missile; and Spear-EW, an electronic warfare variant for stand-in jamming or for use as a decoy.
MBDA UK is the British division of the pan-European missile systems company MBDA. Formed in 2001, the company has developed, both independently and in cooperation, a range of missile systems, including the CAMM missile family, Storm Shadow cruise missile, ASRAAM air-to-air missile and Meteor beyond-visual-range missile (BVRAAM).
