The SPYDER (Surface-to-air PYthon and DERby) is an Israeli short and medium range mobile air defence system developed by the companies, Rafael Advanced Defense Systems with assistance from Israel Aerospace Industries (IAI). The system can fitted atop a Tatra truck, a Mercedes-Benz Actros truck, or a MAN TGS truck. It implements the Python-5 and Derby air-to-air missiles of the same company and shares full commonality with them. Rafael is the prime contractor and IAI is the major subcontractor for the SPYDER program.

SPYDER is a low-level quick-reaction surface-to-air missile system capable of engaging aircraft, helicopters, unmanned air vehicles, drones, and precision-guided munitions. It provides air defence for fixed assets and for point and area defence for mobile forces in combat areas. The two variants of the SPYDER are the SPYDER-SR and the SPYDER-MR. Both systems are quickly reaction, all weather, network-centric, multi-launcher, and self-propelled. The SPYDER launcher is designed to fire Python-5 and Derby surface-to-air missiles. A typical battery consists one central command and control unit, six missile firing units, and a resupply vehicle.

Current operators of the SPYDER missiles system include India and Singapore. Peru's order for the SPYDER was pending as of 2012. Unofficial reports claim that Georgia operated the SPYDER-SR during the 2008 Russo-Georgian War but has never been verified.

Description[edit]

Command and control[edit]

EL/M-2106 ATAR[edit]

Main article: EL/M-2106

The Elta EL/M-2106 Advanced Tactical Acquisition Radar (ATAR) 3D Active electronically scanned array (AESA) surveillance radar is the Command and Control Unit (CCU) for the SPYDER-SR. This radar can track and engage multiple targets simultaneously and can control the missile firing units at a distance away from the CCU.[1] The E/LM-2106 ATAR is a fourth generation defence radar designed by Elta and operates in the L-band wavelength. It is a field proven design that has operated in undesirable environments. The range of detection for a fighter aircraft is 70–110 km. It can detect hovering helicopters at a range of 40 km and UAVs at 40–60 km.[2]

EL/M-2084 MMR[edit]

Main article: EL/M-2084

The radar sensor unit of the SPYDER-MR comprises the EL/M-2084 Multi Mission Radar (MMR) 3D AESA radar. The EL/M-2084 operates in the S-band. It can process up to 1200 targets when in air surveillance mode and also detects targets located 250 km away. When the radar is static, it covers 120° in the azimuth.[3]

Surface to air missiles[edit]

Further information: Python (missile)

Ranges of Interception[edit]

As a short range air defence system, the SPYDER-SR has a short range of interception. The altitude the missiles can reach is 9 km and the maximum range of interception is 15 km.[1] The SPYDER-MR has a greater operation range of 35 km and an altitude engagement of 16 km due to the missiles being equipped with boosters.[4][a]

Python-5[edit]

The Python-5 is currently the most capable air-to-air missile (AAM) in Israel's inventory and one of the most advanced AAMs in the world. As a beyond-visual-range missile, it is capable of "lock-on after launch" (LOAL), and has all-aspect/all-direction (including rearward) attack ability. The missile features an advanced electro-optical imaging infrared seeker (IIR or ImIR) which scans the target area for hostile aircraft, then locks-on for terminal chase.[6]

  • Length: 310 cm
  • Span: 64 cm
  • Diameter: 16 cm
  • Weight: 105 kg
  • Guidance: IR + electro-optical imaging
  • Warhead: 11 kg
  • Speed: Mach 4

Derby[edit]

The Derby is an active radar AAM that provides the SPYDER missile system with a fire-and-forget option due to its active radar guidance.[7]

  • Length: 362 cm
  • Span: 64 cm
  • Diameter: 16 cm
  • Weight: 118 kg
  • Guidance: Active Radar
  • Warhead: 23 kg
  • Speed: Mach 4

Operational use[edit]

During the Russo-Georgian war of 2008, it was believed that Georgia operated the SPYDER-SR.[8][9][10] The Georgian air force could have operated up to four launchers of the SPYDER-SR and it is likely that the system was lost in the conflict.[10]

Export[edit]

Georgia[edit]

Unconfirmed reports claim that a battery of the SPYDER missile system was operated in 2008.[8] No official confirmation exists and the Stockholm International Peace Research Institute (SIPRI) arms transfer database cannot confirm this.[11] Jane's Missiles & Rockets magazine previously cited a Rafael representative claiming that one of the two export customers of the SPYDER missile system already has theirs deployed.[8]

India[edit]

In 2006, India planned to acquire 18 SPYDER-MR systems at a cost of $395.2 million (Rs. 1800 crore) for its air force.[12] The contract was reviewed by the Central Vigilance Commission, the government’s anti-corruption agency, before the agreement was signed in September 2008.[13][14] In August 2009, the multi-billion dollar contract for Israeli anti-aircraft missiles was cleared by the Defence Acquisition Council headed by defence minister AK Antony.[12][15] Although previous estimates of the contract's value was 18 billion rupees ($395.2 million), recent reports indicate a lower value of $260 million.[11][12] The Jerusalem Post contradicts these figures and mentions a price of $1 billion for the purchase of the surface to air missiles.[16] The SPYDER systems were delivered starting in 2012.[11]

Peru[edit]

In March 2012, Peru chose the winners of a $140 million competition meant to upgrade its ageing air defence systems out of the group of 20 defence companies.[17] Amidst the presence of Russia's Rosoboronexport and Chinese firms, the winners were Poland's Bumar Group, Israel's Rafael Advanced Defence Systems, and the USA's Northrop Grumman.[18] Rafael industries is expected to supply six SPYDER-SR systems in this deal.[19]

Singapore[edit]

In 2008, the Ministry of Defence ordered two SPYDER-SR batteries along with 75 Python-5 SAMs and 75 Derby SAMs. They were all delivered during 2011 and 2012.[11]

Confirmed Operators[edit]

 India
  • Indian Air Force – Six SPYDER-MRs along with 300 Python-5 surface to missiles (SAMs) and 300 Derby SAMs in 2013.[11]

Notes[edit]

  1. ^ The offical brochure of the SPYDER missile system by Rafael Advanced Defense Systems contradicts the figures for the interception range for both the SPYDER-SR and SPYDER-MR. The brochure mentions that the interception range of the SPYDER-SR is 20 km instead of the 15 km and 50 km instead of 35 km for the interception range of the SPYDER-MR.[5]
