Tejas Test Fires Derby Missile

2019 ias preliminary exam test series

Tejas, the Light Combat Aircraft today successfully demonstrated an Air-to-Air Beyond Visual Range (BVR) missile firing capability by releasing Derby Air-to-Air BVR missile in RADAR guided mode.

The missile launch was performed in Lock ON after Launch mode for a BVR target in the look down mode and the target was destroyed.

The objective of the test was to assess the Derby integration with aircraft systems on-board Tejas including the aircraft avionics, fire-control radar, launchers and Missile Weapon Delivery System and to verify its performance.

The test was conducted on a Manoeuvrable Aerial Target at the Interim Test Range (ITR), Chandipur. The sensors at ITR also tracked the target and missile.

A safe separation was followed by missile guidance towards RADAR acquired target. The flawless launch was demonstrated with all on-board systems performing satisfactorily and the missile scored a direct hit on the target with complete destruction of it.

Derby (Alto) is a beyond visual range (BVR) air-to-air missile (AAM) developed by Israeli defence company Rafael Advanced Defense Systems to meet the combat needs of the armed forces.

The Derby AAM can be integrated onto a variety of fighter aircraft such as F-5, F-16 Fighting Falcon, Gripen E and Mirage and is capable of engaging aerial threats from short ranges and near-beyond visual range.

Derby can be configured as a surface-to-air missile (SAM) for launch from a Spyder-SR / MR short and medium range mobile air defence system, which also incorporates Python-5 dual waveband imaging infrared (IIR) missile.

Development of the Derby began in early-1980s, while the missile was introduced in mid-1990s. The missile entered service in 1998 and is operational with six countries.

Derby’s variants include I-Derby and I-Derby ER (Extended Range). The upgraded I-Derby AAR missile is equipped with a software-defined active radar seeker and was unveiled at the Aero India 2015 exhibition held in Bengaluru, India.

The I-Derby ER advanced active radar missile was unveiled at the Paris Air Show 2015. It features a solid-state active radar seeker and a dual pulse rocket motor, which provides an operational range of up to 100km.
