The Commander SL radar system is a high performance long/medium range mobile or semi-static 3-Dimensional air surveillance radar. It is a fully digital sensor with an integrated secondary radar capability offering full electronic identification functionality including Mode S and Mode 5. It has advanced Electronic Counter-Counter Measures (ECCM) functionality and other radar management techniques to ensure optimum performance in adverse environmental and electronic conditions. Its dependable detection performance is ready to counter future air threats, including Unmanned Aerial Vehicles (UAVs), cruise missiles and long range stand-off weapons. Equally important for routine day-to-day air policing operations, the radar’s versatile frequency management techniques also enable it to operate in the modern crowded peacetime electronic environment without interference to, or from, other spectrum users.

The Commanders SL is fully interoperable with existing or planned Air Defence Command and Control systems. It can also offer a limited stand-alone Air Battle Management capability, useful for small-scale integrated air defence scenarios, offering great flexibility of employment to the Air Defence Commander.

The Commander SL Radar is fully developed and in service with a leading NATO Air Force. Designed for low and easy maintenance, it has proven in-service reliability and availability with known operating costs based on true, measured operating data.

Acquisition of radars is part of a modernization process for Czech Republic, and in the first phase of the project five radar systems will be procured. The Ministry of Defenses of the Czech Republic and Slovakia has or will launch  international tenders for 3D mobile air defense radars.

The radars will replace the obsolete Soviet-design technology still in the inventory. BAE Systems intends to respond to this tender with is Commander SL Radar, in cooperation with local companies.
