Czech Republic Produces First Platforms for Spyder Missile System on Tatra Trucks to Enhance National Air Defense.
The Czech Republic continues to modernize its air defense with the integration of the Israeli-made Spyder system, developed by Rafael Advanced Defense Systems, onto third-generation Tatra Force 8×8 trucks. The first platforms for these systems have been completed by Tatra Defence Vehicle (TDV), a subsidiary of the Czechoslovak Group (CSG). During a visit to TDV's facility, CZ Defence journalists observed the assembly of Spyder components, including launcher vehicle structures and missile transport containers. This initiative is intended to replace the aging Soviet-designed 2K12 Kub systems with a modern, NATO-interoperable solution, enhancing protection against contemporary aerial threats.

The Spyder system, short for "Surface-to-air Python and Derby," is a modular air defense platform designed to intercept various threats, including aircraft, helicopters, drones, and cruise missiles. It is available in different configurations tailored to specific operational needs. The Spyder-SR (Short Range) version provides coverage up to 15 km with a maximum altitude of 9 km, while the Spyder-MR (Medium Range) extends its reach to 35 km with an altitude of 16 km. The Czech Republic has selected the Spyder-MR variant, equipped with EL/M-2084 MMR/MADR radars from IAI Elta, which provide three-dimensional target detection and tracking. These multi-role radars are already in use by the Czech Armed Forces for air surveillance, ensuring seamless integration of the Spyder system into the country's existing defense infrastructure.
A key aspect of this acquisition is the use of the Tatra Force 8×8 chassis for all system components. Known for its durability and off-road mobility, this chassis enables deployment across varied terrains while ensuring stability during missile launch operations. The vehicles feature armored cabins that provide protection against ballistic threats and fragmentation, ensuring crew safety. Each Spyder battery will include multiple specialized vehicles, such as launchers, command posts, reloading vehicles, and radar units. In total, the Czech Republic has ordered four batteries, which are scheduled for phased delivery between 2025 and 2026, with full operational deployment expected by 2028.
The integration of the Spyder system into the Czech Armed Forces involves a significant technology transfer and an expanded role for the domestic defense industry. Approximately 30% of the program relies on contributions from Czech companies, including RETIA and the Military Technical Institute (VTÚ). This industrial partnership ensures local production of critical components such as missile transport and launch containers, as well as the integration of electronic and communication systems into the vehicles. TDV’s involvement in this program strengthens the country’s defense industry while providing long-term logistical and technical support for system maintenance.
The Spyder systems ordered by Prague will be equipped with Python-5, Derby, and I-Derby-ER missiles, each designed for specific threat engagement. The Python-5, with a range of 15 km, is an electro-optical and infrared-guided missile capable of intercepting highly maneuverable targets. The Derby, equipped with active radar guidance, enables beyond-visual-range interceptions of up to 35 km. The I-Derby-ER variant extends engagement capabilities to 80 km with an additional booster, offering a longer-range protective layer. The missile procurement was finalized in 2023, with deliveries expected in 2027 ahead of the system’s full operational deployment.
This air defense modernization effort aligns with the Czech Republic’s broader military capability enhancements and NATO standardization objectives. Prior to the Spyder acquisition, the country had invested in eight EL/M-2084 MMR radars from Israel’s IAI Elta, delivered between 2021 and 2023. These systems play a crucial role in airspace monitoring and will be fully integrated into the new Spyder batteries. Additionally, the Czech Armed Forces plan to enhance coordination between the 25th Air Defense Missile Regiment and the 26th Air Command and Surveillance Regiment, which already operate these radars for air defense operations.
The deployment of the Spyder MR systems on the Tatra chassis represents a significant step in the Czech Republic’s air defense modernization efforts. This program replaces outdated equipment with an advanced system while ensuring a strong domestic industry role in production and long-term support. By adopting a proven, NATO-compatible platform, the country enhances its defensive capabilities against modern aerial threats while securing critical infrastructure and national airspace.
