Document Introduction

This report is an in-depth independent study conducted by the Mine Warfare Assessment Committee of the Naval Studies Board under the National Research Council, in response to a request from the Chief of Naval Operations. The study aims to comprehensively examine the operational and technological challenges faced by the U.S. Navy in the field of mine warfare (including mining and mine countermeasures) as it enters the 21st century. Based on nine months of intensive research, dozens of service briefings, site visits, and expert deliberations conducted by the committee between August 2000 and April 2001, the report systematically assesses the current status, deficiencies, and future development directions of the U.S. Navy's mine warfare capabilities.

The report begins by clearly stating that mines, as a low-cost, high-effectiveness asymmetric threat, are posing an increasingly serious challenge to U.S. Navy mobility and power projection in littoral waters due to their proliferation and technological advancement. Historical data indicates that since World War 2, mines have caused more damage to U.S. Navy vessels than missiles, air strikes, and submarine attacks combined. However, the U.S. Navy has historically underestimated the importance of mine warfare, treating it as a secondary operational domain, leading to chronic underinvestment in related budgets, training, career development, and equipment modernization. As the Navy's strategic focus shifts towards forward... littoral operations from the sea, this capability shortfall has become a core risk that urgently needs to be addressed.

The main body of the report provides in-depth analysis around several key areas. First, it explores the necessity of establishing mine warfare as a primary naval warfare area on par with air, surface, and submarine warfare, and proposes a systematic mainstreaming implementation path involving doctrine, organization, training, materiel, leadership, personnel, and facilities. Second, the report strongly emphasizes the foundational role of Intelligence, Surveillance, and Reconnaissance (ISR) for mine warfare, criticizing the severe shortcomings in current ISR mission planning, environmental database development, and the utilization of threat mine technology. Third, the report warns that the U.S. Navy's offensive mining capability is rapidly atrophying, with an aging mine inventory and research, development, and procurement programs nearly at zero, resulting in the loss of an important strategic and tactical coercive option.

Regarding mine countermeasures capabilities, the report evaluates two distinct areas: open-ocean (water depths greater than 40 feet) and littoral (from 40 feet to the beach). For open-ocean mine countermeasures, the report provides a detailed assessment of existing dedicated MCM forces (such as MCM/MHC class ships, MH-53E helicopters, Explosive Ordnance Disposal units) and the seven organic mine countermeasures systems under development at the time (e.g., Remote Minehunting System, Airborne Laser Mine Detection System, etc.), pointing out critical flaws such as the lack of an overarching operational concept, a system integration architecture, and clearly defined capability requirements. For the more challenging littoral mine countermeasures, the report notes this area is the weakest link in current capabilities, heavily reliant on a small number of EOD/Expeditionary MCM units, unable to meet the requirements for rapid lane clearance in large-scale amphibious assaults, and discusses the potential of alternative forcible breaching options like the Harvest Hammer system.

Ultimately, the report distills seven high-priority overarching recommendations aimed at comprehensively enhancing the U.S. Navy's mine warfare readiness. These recommendations encompass mainstreaming mine warfare, strengthening ISR, rebuilding a credible joint mining capability, modernizing dedicated MCM forces, integrating organic MCM systems, improving littoral MCM capabilities and clarifying service responsibilities, and reducing friendly force vulnerability to the mine threat. This report is not only a technical assessment but also a call for necessary change regarding U.S. Navy culture, organizational priorities, and resource allocation, providing decision-makers, planners, and operators with a fact-based, sobering examination and a clear roadmap for action.
