TPS-77 MRR Long Range Air Surveillance Radar

The TPS-77 Multi Role Radar is a modern long range air surveillance system designed to give air forces reliable early warning and airspace control in contested environments. Built for mobility and survivability, the radar supports national air defense, expeditionary operations, and joint force integration. It is widely used by U.S. allies for persistent monitoring of aircraft, cruise missiles, and unmanned threats.

Manufacturer

The TPS-77 MRR is developed and produced by Lockheed Martin, a U.S. defense prime contractor with deep experience in radar, sensors, and integrated air and missile defense systems.

Speed and Range

The radar is optimized for long range detection rather than speed tracking of a single target type. It can detect and track fast moving fighter aircraft, ballistic trajectories at altitude, and low flying cruise missiles. Maximum instrumented detection range exceeds 470 kilometers, with full 360 degree azimuth coverage and high elevation tracking for layered air defense.

Cost / Price

Exact pricing depends on configuration, logistics, and support packages. Open source estimates place unit costs in the tens of millions of U.S. dollars, typically bundled within broader air defense or command and control programs.

Operational Use

TPS-77 MRR supports air sovereignty missions, early warning, ground controlled interception, and integration with surface to air missile systems. Its solid state AESA design improves reliability while reducing maintenance demands in harsh climates.

FAQs

What is the TPS-77 MRR used for?
