Minuteman III Guidance Replacement Program (GRP)

The Minuteman III Guidance Replacement Program (GRP) is a Major Defense Acquisition Program (MDAP) focused on maintaining and upgrading guidance systems for the LGM-30 Minuteman III intercontinental ballistic missile system. Operating under Acquisition Category ID and following the Major Capability Acquisition pathway, this program encompasses comprehensive guidance system sustainment, including repair, replacement, and modernization of critical navigation and control components. The program represents a crucial element in maintaining the reliability and accuracy of the U.S. nuclear deterrent force.

Contract awards under this program range from small purchases of test equipment and electronic components ($7,275-$110,325) to major guidance system repair and replacement efforts exceeding $236 million. The Department of the Navy Strategic Systems Programs and Air Force organizations are the primary contracting authorities. Key contractors include The Boeing Company, The Charles Stark Draper Laboratory, Inc., with work primarily performed in Newark, Ohio. Typical contract vehicles include both firm-fixed-price and cost-plus arrangements (fixed fee and award fee), with performance periods ranging from several months to multiple years. The majority of contracts are awarded without set-aside designations, though some smaller procurements utilize Total Small Business set-asides. Deliverables include guidance system repairs, technical services, research and development, test equipment, and various support systems such as alignment test sets and data conversion services.
