The 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 system is fitted atop a Tatra truck, a Mercedes-Benz Actros truck, a MAN TGS truck, Scania P-series truck, Dongfeng truck, or a TELAR. It implements the Python-5 and Derby missiles of the same company. The SPYDER launcher is designed to fire Python-5 and Derby surface-to-air missiles which share full commonality with the air-to-air missiles. There are two variants of the SPYDER: the SPYDER-SR (short range) and the SPYDER-MR (medium range). Both systems are quick reaction, all weather, network-centric, multi-launchers, and self-propelled. A typical battery consists one central command and control unit, six missile firing units, and a resupply vehicle. The SPYDER-SR uses the EL/M-2106 ATAR radar while the SPYDER-MR incorporates the EL/M-2084 MMR radar. The latter is the same radar used by the Iron Dome system currently in service with the Israel Defense Forces.
