Kh-66 / AS-7 “KERRY”
The Kh-66 and Kh-23 Grom air to surface missiles, designated by the NATO as AS-7 Kerry, arose by a request from the North Vietnamese Government for a missile that could counteract the American AGM-12 Bullpup missile. In 1966 was designed a missile named Kh-66, which was actually the body of an AA-3 Anab air to air missile in which a beam-riding guide system and a 100kg warhead were installed. They started to be produced in 1968 for the MiG-21 PFM fighter aircraft, but they had the drawback that launcher aircraft had to aim at the target constantly. Meanwhile, another version known as Kh-23 was developed for the new Soviet MiG-23 Flogger aircraft, but suffered numerous delays and was not ready until 1973. There were different versions such as the Soviet Kh-23L and Kh-23M with laser guidance system, the A-921 built in Romania, the Grom A missile from Yugoslavia and Grom B variant made in Serbia.
