ON AUGUST 19TH a senior Pentagon official confirmed what had previously only been hinted at: America is supplying Ukraine with High-speed Anti-Radiation Missiles (HARM). The missiles have been playing an important role in Ukraine’s spectacular offensive in Kharkiv province, as well as a separate attack in the south. Launched from an aircraft, HARM homes in on and destroys air-defence radar. The missiles represent a serious challenge to Russia. Even if not fired, the threat they pose can force radar operators to turn off their sets and lie low. Ukraine’s air force, as a result, may not quite fly with impunity, but it has greater freedom than before.
