News Media Resources: DTRA Fact Sheets - Combating Terrorism Technology Program

The Massive Ordnance Penetrator (MOP) technology demonstration is developing a conventional 30,000-pound class penetrator bomb designed to defeat hard and deeply buried targets (HDBTs) such as bunker and tunnel facilities.

Funded and managed by the Defense Threat Reduction Agency (DTRA), a Department of Defense combat support agency, the MOP effort is a part of the DTRA Hard Target Defeat Program that develops and demonstrates technologies to hold at risk and defeat military missions protected in HDBTs.

The Air Force Research Laboratory (AFRL) Munitions Directorate is executing the MOP contract and providing management and technical support to the technology demonstration. AFRL awarded the $30 million MOP contract to the Boeing Company on Nov.1, 2004. The MOP is being developed in three phases. Boeing successfully completed Phase I, Concept Refinement, of the MOP technology demonstration in May 2005. Phase II started in June 2005 and included detailed design and preliminary testing as well as long lead items for Phase III, Weapon Performance Demonstration. During Phase III, research and development flight tests from a B-52 aircraft are planned between Nov. 2007 and July 2008. These tests are designed to measure the penetration and lethality performance of the MOP weapon on bunker and tunnel targets constructed at DTRA’s WMD National Testbeds located at the White Sands Missile Range, N.M.

The MOP is approximately 20.5 feet long, with a 31.5-inch diameter and a total weight of slightly less than 30,000 pounds. The weapon will carry over 5,300 pounds of explosive material and will deliver more than 10 times the explosive power of its predecessor, the BLU-109. Guided by Global Positioning System navigation, the MOP has cropped wings for improved agility and storable grid fin controls that also facilitate internal carriage.

The MOP is designed to permit carriage inside both the USAF B-52 and B-2 bombers. Although the technology demonstration test drops will be conducted from a B-52, the Air Force Air Armament Center at Eglin Air Force Base (AFB), Fla., issued a sources-sought notice to explore integration of the MOP on the B-2 bomber.

The AFRL mission is to lead the discovery, development and integration of affordable warfighting technologies for air and space forces. AFRL headquarters is located at Wright Patterson Air Force Base, Ohio. The AFRL Munitions Directorate, Eglin AFB, Fla. develops, demonstrates and transitions science and technology for air-launched munitions for defeating ground fixed, mobile/relocatable, air and space targets to assure pre-eminence of U.S. air and space forces.

Defense Threat Reduction Agency

DTRA safeguards America and its allies from weapons of mass destruction by providing capabilities to reduce, eliminate, and counter the threat, and mitigate its effects. The agency conducts studies and develops technology and procedures to counter existing threats, and develops specific capabilities for their defeat. This Department of Defense combat support agency is located at Fort Belvoir, Va., and operates field offices worldwide.
