Kh-28

The Kh-28 (Russian: Х-28; Nisan-28; NATO: AS-9 'Kyle') was the first Soviet anti-radiation missile (ARM) for tactical aircraft. It entered production in 1973 and is still carried on some Sukhoi Su-22s in developing countries but is no longer in Russian service. Use of the Kh-28 was restricted by its weight, limited seeker head, bulk and fuelling requirements, and it was superseded by the smaller, solid-fuel Kh-58 (AS-11 'Kilter') in the early 1980s.
