 US Strategic Nuclear Submarine Succession Difficulty

US Navy Nuclear Submarine

Global Times reported that the U.S. militarys current Ohio class strategic nuclear submarine is about to retire, while the new generation of Colombia class has suffered serious budget overruns and time delays. Seeing that the sea-based nuclear power as an important pillar of the trinity of the U.S. nuclear power will be green and yellow.

Reported that the Ohio class nuclear submarine was built in the 1980s, has been in service for 40 years, will be decommissioned in the next few years, the urgent need for a new strategic nuclear submarine in 2031 succession. According to the original plan, the Navys new generation of Columbia strategic nuclear submarines will be built from October 2020, a total of 12, and the cost of procurement and research and development will be as high as $128 billion. It also makes the Colombian nuclear submarine the third most expensive weapon system on the Pentagons purchasing list, following the F-35 stealth fighter plane ($406 billion) and the missile defense program ($153 billion).

However, the latest report released by the US Government Accountability Bureau shows that the related procurement cost estimates and design objectives are not credible. Shelby Oakley, director of ship projects at the Bureau of Accountability, said current cost estimates might not meet such large-scale equipment procurement.

Defense News further disclosed the construction risks faced by the nuclear submarine project. As the only nuclear submarine shipyard in the United States, General Dynamics and Huntington Ingels Industries are busy solving the construction problems of Virginia-class attack nuclear submarines and meeting the temporary Virginia class delivery acceleration requirements of the U.S. Navy, with no regard to the Columbia class nuclear submarine project.

Shi Hong, executive editor of Shipborne Weapons, told the Global Times that the main reason why the U.S. militarys nuclear submarine construction is stretched to the limit is that the overall strength of the U.S. shipbuilding industry has declined, and that the U.S. military can only choose contractors from a handful of shipyards, resulting in a concentrated construction project, a full schedule and a lack of task margin. Another reason is the problem of project management in the U.S. Army. Large-scale equipment projects such as nuclear submarines must propel the process in strict accordance with the scheduled time nodes, and at the same time, risk prediction should be made to prevent the pull-in-one problem.
