Massive Ordnance Penetrator

The Massive Ordnance Penetrator (MOP) is a Major Defense Acquisition Program managed by the Department of Defense under the Major Capability Acquisition pathway with an Acquisition Category IC designation. The program develops and sustains a large, precision-guided, air-dropped conventional munition designed to destroy hardened, deeply buried targets. The MOP system includes the primary penetrator warhead, tailkit assemblies, mission computers, and associated support equipment.

Contract awards from 2019-2023 show the Air Force Life Cycle Management Center at Eglin Air Force Base as the primary funding agency, with most awards structured as firm-fixed-price delivery orders ranging from $50,000 to $17 million with performance periods of 1-5 years. The Boeing Company serves as the primary systems integrator and logistics support contractor, with major recurring work in St. Louis, Missouri. Key subcontractors include L3Harris Fuzing and Ordnance Systems, Dynetics, Northrop Grumman, and Moog Inc. Warhead case manufacturing is split between Superior Forge & Steel Corp. (Lima, Ohio) and Ellwood National Forge Company (Irvine, Pennsylvania). While most contracts have no set-aside designation, occasional small business set-asides are used for specialized equipment and components. The program encompasses ongoing development work through cost-plus-fixed-fee contracts for modifications and smart fuze integration, as well as sustained contractor logistics support through various indefinite delivery vehicles.
