The US military has tested a ground-launched cruise missile with a range of over 500km, the Pentagon confirmed. Such weapons were banned under the INF arms control treaty, which the US exited this month. The flight test of a “conventionally configured ground-launched cruise missile” was conducted on August 18 at a range on San Nicolas Island, California, the US Department of Defense said Monday. After a successful launch, the missile struck its target more than 500km (310 miles) away. Weapons with a range of between 500km and 5,000km were banned under the Intermediate-Range Nuclear Forces treaty, a key arms control mechanism that helped de-escalate Cold War nuclear tensions when it was signed in 1987.
