AN/FPS-117
The AN/FPS-117 is an L-band active electronically scanned array (AESA) 3-dimensional air search radar first produced by GE Aerospace in 1980 and now part of Lockheed Martin. The system offers instrumented detection at ranges on the order of and has a wide variety of interference and clutter rejection systems.

Oko
Oko (Old ) is a Russian (previously Soviet) missile defence early warning programme consisting of satellites in Molniya and geosynchronous orbits. Oko satellites are used to identify launches of ballistic missiles by detection of their engines' exhaust plume in infrared light, and complement other early warning facilities such as Voronezh, Daryal and Dnepr radars. The information provided by these sensors can be used for the A-135 anti-ballistic missile system which defends Moscow. The satellites are run by the Russian Aerospace Forces, and previously the Russian Aerospace Defence Forces and R

J/FPS-5
The J/FPS-5, or also known as the Gamera Radar, is an airspace warning and control radar device operated by the Japan Air Self-Defense Force. It is a large fixed 3D radar for radar sites, and is a phased array radar that uses an active phased array antenna (AESA) and is also capable of detecting and tracking ballistic missiles. It was made by Mitsubishi Electric.
