The main difficulty came in the design of the APR-28 guidance system undertaken by CKB-111 (later NPO Avtomatika). This meant that the Kh-28 missile was not ready until the 1970s. Flight trials were carried out on a Yak-28N, but by then the Yak-28 had ceased production and was perceived as obsolete, and the K-28P system was cancelled. Instead the Kh-28 was adapted for use by standard attack aircraft, in particular the Su-24

Design
The Kh-28 was the first liquid-fuel Soviet anti-radiation missile and was quickly replaced by the solid-fuel Kh-58 missile, according to research from Dr. Carlo Kopp, the editor in chief of Air Power Australia.
The design of the Kh-28 was similar to – but smaller than – Raduga's Kh-22

(AS-6 'Kingfish') anti-shipping missiles. The Su-24 could carry one under each wing, and used the onboard ''Filin'' ('Eagle Owl') targeting system. The Su-17M could only carry one Kh-28 on the centreline, and used the ''Myetyel''/''Metel'' ('Blizzard') system in a pod under the right wing, later replaced by the ''Vyuga'' ('Snowstorm') pod.
The APR-28 seeker on the original Kh-28 could only target the MIM-14 Nike-Hercules
The Nike Hercules, initially designated SAM-A-25 and later MIM-14, was a surface-to-air missile (SAM) used by U.S. and NATO armed forces for medium- and high-altitude long-range air defense. It was normally armed with the W31 nuclear warhead, but ...

Operational history
The Kh-28 entered service with the Soviet Air Force in 1973, and has been widely exported. It was cleared for use on the Su-17M/Su-20/Su-22M, Su-24M, Tupolev Tu-16, Mikoyan-Gurevich MiG-25BM, MiG-27 and Tupolev Tu-22M aircraft. It was also tested on an Antonov An-12

A missile believed to be a Kh-28 was captured in Iraq by US forces during the first Gulf War in April 1991. One man was burnt by RFNA from the oxidiser tank while he was making it safe.
