United States targets nuclear-powered ships to compete with China

The United States is planning to pivot its maritime strategy toward nuclear-powered commercial vessels to compete with China's dominance in the global shipbuilding industry. According to UNCTAD data, China accounted for 54.57% of global shipbuilding tonnage in 2024, while the United States held only 0.04%. China also maintains a significant lead in future orders, securing 74.4% of contracted tonnage in 2024.

Stephen Carmel, Administrator of the U.S. Maritime Administration (MARAD), stated that competing with China on the cost of conventional vessels is unfeasible. Instead, the U.S. aims to leverage its technological advantage in naval nuclear reactors—currently used in submarines and aircraft carriers—to develop a new generation of commercial ships.

British company Core Power is leading the development of maritime nuclear reactors designed to power large vessels for extended periods with reduced fossil fuel dependency. The company has raised approximately $200 million from investors, including Japanese groups such as Mitsui, Mitsubishi, and Sumitomo. The first nuclear-powered commercial vessel could begin construction as early as 2028.
