The U.S. Department of Defense is moving forward with plans to dismantle and destroy hundreds of rocket motors from retired intercontinental ballistic missiles, marking a significant step in the long-term management of legacy nuclear-era systems.
The initiative, led by Space Systems Command, seeks industry partners capable of safely demilitarizing components from the Minuteman II program. A recent Request for Information outlines the need to process at least 178 rocket motors, with the possibility of expanding the total to over 280 units.
These motors, originally used in Cold War-era missiles, are currently stored at Camp Navajo in Arizona. The plan envisions a multi-year effort, potentially spanning up to a decade, with contractors expected to handle between 12 and 48 motors annually, depending on capacity and logistics.
Demilitarizing these components presents significant technical and environmental challenges. The solid rocket propellant inside the motors remains chemically active, even decades after production. The preferred method, known as “washout,” involves extracting the propellant using high-pressure water, creating waste that must be carefully treated to meet environmental standards.
Alternative disposal methods, such as controlled burning, are also under consideration, though each approach carries its own safety and regulatory implications. The Pentagon is seeking detailed proposals from contractors on how they would manage both the materials and the associated waste streams.
The physical scale of the rocket motors adds further complexity. Some units weigh tens of thousands of pounds and require specialized equipment for transport and handling. Once the propellant is removed, the remaining structures, including titanium casings, must be rendered unusable to meet strict demilitarization standards.
The program requires compliance with “5X certification,” the highest level of demilitarization, ensuring that all materials are permanently disabled and cannot be repurposed for military use. This standard reflects both security concerns and obligations tied to international arms control agreements.
The effort is being managed through the Rocket Systems Launch Program, which has historically repurposed some retired missile components for space launch applications. However, not all motors are suitable for reuse, making safe destruction a necessary part of the process.
The renewed request for industry input follows an earlier inquiry issued in 2025, suggesting that the Pentagon is refining its approach and seeking broader participation from the private sector.
As the United States continues to modernize its defense capabilities, the program highlights the ongoing challenge of safely disposing of aging strategic systems while adhering to environmental, security, and treaty requirements.
