WDU-36/B

WDU-36/B. The WDU-36/B is a specialized warhead assembly designed for use in the AGM-130 stand-off missile system. It was developed to provide the United States Air Force with a potent, precision-guided weapon capable of destroying hardened or deeply buried targets. The system integrates a penetrating warhead with a rocket-boosted glide vehicle to deliver a significant explosive payload from a safe stand-off distance.

Overview

The WDU-36/B forms the destructive element of the AGM-130 weapon, a system developed from the earlier GBU-15 glide bomb. Its primary operational role is to engage and neutralize high-value, well-protected targets such as command bunkers, aircraft shelters, and key infrastructure. The warhead's design emphasizes both penetration capability and high explosive power, making it a key component in the United States Air Force's inventory of air-to-ground munitions during the late 20th century. Deployment of the AGM-130 equipped with this warhead provided tactical aircraft like the F-15E Strike Eagle and the F-111 Aardvark with a formidable long-range strike option.

Design and development

The design and development of the WDU-36/B was led by General Dynamics under contract for the United States Air Force. It was created specifically to address the requirement for a warhead compatible with the new rocket-boosted AGM-130 airframe, which offered greater range and flexibility than its unpowered predecessor. Engineers focused on optimizing the warhead's casing and internal configuration to work in concert with the missile's inertial navigation system and terminal guidance options, which included a television or imaging infrared seeker. The selection of A-1 as the main explosive filling was based on its proven stability and high-blast characteristics, suitable for the weapon's intended targets.

Operational history

The AGM-130 missile equipped with the WDU-36/B warhead entered service with the United States Air Force in the 1990s. It saw combat use during Operation Desert Storm, where it was employed against strategic Iraqi targets, and later during NATO's Operation Allied Force in the Kosovo War. The weapon provided crews the ability to launch from outside the range of many air defense systems, improving aircraft survivability. Its performance in destroying hardened facilities validated the concept of a rocket-powered, precision-guided munition with a specialized penetrating warhead. The system remained in the inventory for several decades, though newer weapons like the Joint Direct Attack Munition eventually supplemented its role in many missions.

Variants

The primary variant is the WDU-36/B warhead as integrated into the standard AGM-130A missile. A related development was its use with the AGM-130C, which was designed with an imaging infrared seeker for improved adverse-weather and night-time capability. The fundamental warhead design remained consistent across these AGM-130 variants. Other experimental or proposed configurations for different missile bodies may have been studied but did not reach widespread production or deployment. The warhead itself is a distinct component from the guidance kits used on other United States munitions like the Paveway series of laser-guided bombs.

Specifications

The WDU-36/B is a blast-penetration warhead. Its primary explosive filling is the A-1 explosive formulation, known for its reliable and powerful blast effect. The warhead is triggered by an impact fuze designed to detonate after the weapon has penetrated a target's surface or structure. It is physically and electronically integrated into the airframe of the AGM-130 missile, which is powered by a Thiokol solid-fuel rocket motor. The complete AGM-130 weapon system is typically launched from tactical aircraft such as the F-15E Strike Eagle, the F-111 Aardvark, and the F-4 Phantom II.
