The US and the Soviet Union sign the Intermediate-Range Nuclear Forces Treaty, agreeing to remove all intermediate-range (620 miles to 3,415 miles) missiles from Europe. The agreement results in the deactivation of six USAF tactical missile wings equipped with Ground-Launched Cruise Missiles (GLCM).
The Air Force Research Laboratory has signaled to industry it wants to develop a low-cost hypersonic cruise missile to deliver a wide range of payloads at a range up to 500 nautical miles.
