The H-4 SOW (Stand-Off Weapon) is a precision-guided glide bomb manufactured by Pakistan and deployed by the Pakistan Air Force, capable of striking targets at stand-off range. It has a terminal guidance system based on an infrared homing seeker, which identifies the target during the final stage of flight. Designed to hit targets out to 120 km, the bomb may have the capability to evade radar.

According to Pakistani press reports, the H-4 glide bomb was created by Pakistan's National Engineering and Scientific Commission (NESCOM), working in collaboration with the Pakistan Missile Organisation and Air Weapons Complex in Pakistan. A lighter version of the H-4 has also been produced, the H-2 SOW, which has a stated range of 60 km.
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 Dassault Mirage 5 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 homing seeker and has a range of 120 km.

It is believed that the Raptor I and Raptor II are being manufactured under license in Pakistan by the National Engineering and Scientific Commission (NESCOM) as the H-2 and H-4, respectively.
