The IRIS-T (Infra Red Imaging System Tail/Thrust Vector-Controlled) is a German-led program to develop a short-range infrared homing air-to-air missile to replace the AIM-9 Sidewinder found in some NATO member countries. Any aircraft capable of firing the Sidewinder is also capable of launching the IRIS-T.[4]

History[]

In the 1980s, NATO countries signed a Memorandum of Agreement that the United States would develop a medium-range air-to-air missile to replace the AIM-7 Sparrow, while the UK and Germany would develop a short-range air-to-air missile to replace the AIM-9 Sidewinder. The US design developed as the AIM-120 AMRAAM, while the UK-German design developed as the AIM-132 ASRAAM.[citation needed]

The roots of the ASRAAM dated back to 1968 when development began on the Hawker Siddeley SRAAM ('Taildog'), but this project ended in 1974 with no production orders. This work was dusted off for the UK/German effort, with the Germans providing a new seeker, and the UK providing most of the remaining components. In the intervening time, the need for high maneuverability was downgraded in favor of greater range.[citation needed]

After German reunification in 1990, Germany found itself with large stockpiles of the Soviet Vympel R-73 missiles (NATO reporting name: AA-11 Archer) carried by the MiG-29 Fulcrum and concluded that the AA-11's capabilities had been noticeably underestimated.[5] In particular, it was found to be both far more maneuverable, and far more capable in terms of seeker acquisition and tracking than the latest AIM-9 Sidewinder.[6] In 1990 Germany withdrew from the ASRAAM project, while the UK resolved to find another seeker and develop ASRAAM according to the original requirements.[7]

In late 1990, the US partnership expressed similar concerns and embarked on an upgrade to the existing Sidewinder design to provide increased maneuverability and IRCCM (infrared counter counter measures) performance, i.e. measures to counter infrared countermeasures (IRCM). This program was designated AIM-9X.[8]

Missile characteristics[]

In comparison to the AIM-9L Sidewinder, the IRIS-T has higher ECM-resistance and flare suppression.[9] Improvements in target discrimination not only allows for 5 to 8 times longer head-on firing range than the AIM-9L. It can also engage targets behind the launching aircraft, the latter made possible by the extreme close-in agility allowing turns of 60 g at a rate of 60°/s via thrust vectoring and LOAL capability.[10][3]

The Royal Norwegian Air Force (RNoAF) has tested a new air-to-surface capability developed by Diehl BGT Defence for the IRIS-T. A proof of concept test firing to acquire, track, and engage a target representing a small fast attack boat was conducted in Norway in September 2016, where the IRIS-T missile was launched from an RNoAF F-16AM multirole aircraft. For the air-to-surface role, the missile retains the same standard IRIS-T AAM hardware configuration, including the HE warhead and IIR guidance package, with only an updated software insertion required to deliver the additional ground attack capability.[11] This basic air-to-ground capability provides the ability to acquire, track and engage individual ground targets like boats/ships, small buildings and vehicles.[12]

In addition, the IRIS-T has the unique ability, in comparison to other similar missiles such as the AIM-9X, to target and shoot down other air-to-air and surface-to-air missiles thus offering 360° defence capability.[13][3] In fact, a surface launched variant of the IRIS-T the IRIS-T SL actually has even further enhanced capabilities capable of destroying aircraft, helicopters, cruise missiles, air-to-surface missiles, anti-ship missiles, anti-radar rockets and large-calibre rockets. It also has high probability of a killing shot against UAVs and other small maneuvering threats at very-short and medium-range distances.[14]

Development partners[]

In 1995, Germany announced the IRIS-T development program, in collaboration with Greece, Italy, Norway, Sweden and Canada. Canada later dropped out, while in 2003 Spain joined as a partner for procurement.[15] The German Air Force took first delivery of the missile on 5 December 2005.[16]

Workshare arrangements for IRIS-T development are:[1]

  • Germany 46%
  • Italy 19%
  • Sweden 18%
  • Greece 13%
  • 4% split between Canada and Norway.

Variants[]

IDAS[]

The IDAS variant is a navalized version of the missile, is also being developed for the new Type 212A submarine of the German Navy. IDAS is supposed to engage air threats, small or medium surface vessels or near land targets.

IRIS-T SL[]

Within the MEADS program, the German Air Force plans to integrate a surface-launched (SL) radar-guided version of the missile, called IRIS-T SL. It has a pointed nose, unlike the regular IRIS-T.[17] The IRIS-T SL qualification tests were completed during January 2015 at the Denel Overberg Test Range in South Africa.[18] It is built in two variants IRIS-T SLS (short-range)[19] and IRIS-T SLM (medium-range).[20]

SAM Version[]

The Swedish Army is fielding a ground launched version of the IRIS-T, designated RBS 98, to replace the RBS 70 missile system. Four missiles are carried on a special version of a Bv 410 tracked, armored vehicle.[21]

The Norwegian Army has decided to acquire a "Mobile Ground Based Air Defence System" in a direct acquisition with Kongsberg Defence & Aerospace. The deliveries are planned for 2018 to 2021 and the system will reuse NASAMS command and control and its network solutions, to create a "highly mobile, short-range air defence system".[22] The project includes six modified M113 vehicles carrying IRIS-T-missiles.[23]

A version with a Lockheed Martin command and control station and SAAB Giraffe 4A AESA radar was shown at IDEX 2019 under the name Falcon.[citation needed]

Air-to-ground[]

For the air-to-surface role, the only difference from air-to-air version is an updated software insertion required to deliver the additional ground attack capability. Tested by Royal Norwegian Air Force.[24]
