Rafael Armament Development Authority, the MBT Missile Division and Elta Radar Division of Israel Aircraft Industries have announced the SPYDER Surface-to-air PYthon 5 and DERby Air Defence Missile System. Rafael is the prime contractor and IAI the major subcontractor for the SPYDER program.
Three SPYDER-SR (short-range) systems have been sold to an undisclosed country. The system was displayed for the first time at the Paris Air Show 2005 in Le Bourget. Company firing tests of the system are currently underway.
In June 2006, SPYDER was selected by the Indian Army.
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 SPYDER-SR system has 360° engagement capability and the missiles can be launched from the full-readiness state in less than five seconds from target confirmation. The kill range is from less than 1km to more than 15km and at altitudes from a minimum of 20m to a maximum of 9,000m. The system is capable of multi-target simultaneous engagement and also single, multiple and ripple firing, by day and night and in all weathers.
Rafael developed a medium-range version, SPYDER-MR, which has a range over 35km at altitudes from 20m to 16km. SPYDER-MR carries eight missiles while SPYDER-SR has four. SPYDER-MR also has a new IAI/Elta MF-STAR surveillance radar.
SPYDER System Components
The main components of the SPYDER system are the truck-mounted command and control unit, the missile firing unit with Python 5 and Derby missiles, a field service vehicle and missile supply vehicle.
The vehicles are air-conditioned and also provide protection against Biological and Chemical Warfare (BCW). The system is based on a modular design and system maintenance in the field is through very quick module replacement.
SPYDER system includes the following main components:
*
Truck mounted Command and Control Unit (CCU) with mounted radar, IFF and communication equipment
*
Truck mounted Missile Firing Units (MFU) and communication equipment
*
Combination of Derby and Python-5 missiles (equipped with RF and IIR seeker heads respectively)
*
Field Service Vehicle
*
Missiles Supply Vehicle
*
Ground support and special test equipment
*
Built-in and add-on training equipment
Modes of Operation
The system can launch missiles in two modes of operation: Lock On Before Launch (LOBL) and Lock On After Launch (LOAL). The slant launching method, unlike vertical launch, allows LOBL so the missile's on-board seeker is locked on to the target before launch. The LOBL mode allows the Squadron Commander to confirm the missile is locked on to the designated target prior to launch, gives high kill probability against short-range high-manoeuvring targets and enables the engagement of designated targets by add-on optical sensors.
A typical SPYDER squadron consists of one mobile Command and Control Unit (CCU) and four Mobile Firing Units (MFU).
The CCU and MFUs each have their own built-in power supplies. The system features an automated computer, assisting the operators in the successful completion of hostile target interceptions in intense battlefield environments. The mobile CCU is equipped with a surveillance radar and two operator stations. There is a radio datalink between the CCU and the four MFUs.
The CCU combines data from the local surveillance radar and from upper tier command and control centres up to 100km away. There is also provision for receiving Air Situation Pictures from other datalinks. The Air Situation Picture (ASP) is displayed at the operator's workstation in the command centre. When the operator decides to launch, an automatic procedure is initiated. The CCU assigns the target to the appropriate launch unit.
If the target is within acquisition range the missile is launched in LOBL mode. If the target is beyond seeker acquisition range the missile is launched in LOAL mode. The seeker searches for the target and switches to homing phase when the target is acquired.
Both the Derby and the Python 5 missiles can operate in LOBL and LOAL modes. The target is destroyed by the warhead blasting on impact or by proximity fuse.
The advantages of LOBL are threefold:
*
It allows the Squadron Commander to positively confirm that the missile is locked on the target prior to launch
*
It increases the probability of kill (PK) for short range high manoeuvring targets.
*
It also enables designated targets engagement by add-on optical sensors.

Python 5 Air-to-Air Missile
The Python 5 missile is Rafael's new very high agility dogfight air-to-air missile. Python 5 is a development of the Python 4 with a dual-band focal plane array and Imaging Infrared (IIR) seeker which gives a very wide field of view.
Python 5 retains the same airframe - with pitch and yaw control, delta-shaped canards and two roll control swept fins and the same rocket motor, warhead and fuse - as the Python 4 missile. The wide field of view allows LOAL at an angle of more than 100° off boresight. The dual-band seeker gives increased detection range, improved target discrimination against background clutter and a lower false target acquisition rate.
In LOAL mode, the target data is transferred from the command and control unit via the launcher to the missile. The missile's guidance and control systems are active for a three times longer period than for the earlier Python, enabling the missile to counter targets making evasive manoeuvres. The high explosive fragmentation warhead is fitted with an active laser proximity fuse.
Derby Air-to-Air Missile
The Derby missile is a medium-range, active radar-guided missile originally developed for the air-to-air role. The air defence missile has all-weather and beyond visual range capability.
Derby has a similar body design to the Python missile. An active RF radar/infrared seeker, developed by IAI, is installed in the nose of the missile. The missile incorporates an advanced programmable ECCM system. Derby operates in LOBL mode for short-range target engagement and LOAL mode for medium-range engagements.

aunque a algunos no les guste el gepard, por lo menos provee cierta garantia de cobertura a los leos, la cual era practicamente inexistente, si bien no es lo ideal genera un cierto tipo de proteccion aunque muy limitada, puesto que el spyder tiene un rango efectivo de 63 y 15 klm respectivamente con cada misil frente a los casi 6 del gepard....y aciento lo de do335, creo que mas bien se vendieron como paquete por los leos2A4, sin embargo no me quejo,saludos
o leí que el Spyder tiene una cota mínima de altura de 20 mts. para derribos, de ser así ante un ataque de helos a menor altitud queda fuera de servicio de inmediato ello no quita las execelentes prestaciones que le darían al ECH o la FACH en lo que respecta a defensa aérea.
