Three successful tests were conducted, the last one in 2003, which led to field deployment on the Dassault Mirage III and Mirage V strike fighters of the Pakistan Air Force. It has also been stated that the H-4 will be integrated with the PAF's new multi-role combat aircraft, the JF-17, which is replacing the ageing fleet of Mirage III and Mirage V aircraft. All Pakistani JF-17 fighters, from the initial JF-17 Block 1 model to the final Block 3 version, will be capable of launching the H-4.

The H-4's stated range of 120 km and its glide bomb design has led to speculation that it may be a copy or a Pakistani variant of the Denel Raptor II glide bomb, which is also guided by an infrared imaging seeker and has a range of 120 km. There has been much confusion regarding the actual identity of the H-4. Many Indian sources state that the weapon is actually a beyond visual range air-to-air missile. However, Pakistani sources state that the H-4 is a "beyond visual range bomb".
