The AN/FLR-9 is a type of very large circular "Wullenweber" antenna array, built at nine locations during the cold war for HF/DF direction finding of high priority targets.

The worldwide network, known collectively as "Iron Horse", could locate HF communications almost anywhere on the planet.

Because of the exceptionally large size of its outer reflecting screen (1056 vertical steel wires supported by 96 120-foot towers), the FLR-9 was commonly referred to by the nickname "Elephant Cage."

Constructed in the early to mid 1960s, by the end of 2014 only the FLR-9 at Elmendorf-Richardson in Alaska was still operational.
