The missile test was conducted on 18 August at 2:30 p.m. PDT (9:30 p.m. GMT) from San Nicolas Island, California, and the Pentagon stated that "the test missile exited its ground mobile launcher and accurately impacted its target after more than 500 kilometres of flight".
"The Department of Defence conducted a flight test of a conventionally-configured ground-launched cruise missile off the US West Coast Sunday. We are currently evaluating the results of the test", Lt. Col. Carla Gleason told reporters.
According to US defence officials, "data collected and lessons learned from this test will inform the Department of Defence’s development of future intermediate-range capabilities".
The INF Treaty required that the United States and Russia eliminate and permanently forswear all of their nuclear and conventional ground-launched ballistic and cruise missiles with ranges of 500 to 5,500 kilometres (310 to 3,417 miles).
