Russia Allegedly Gives China Submarine-Quieting Tech as 90% Chip Support Fuels Moscow's War

Summary
Retired Rear Adm. Mark Montgomery said Russia may be transferring submarine-quieting technology to China, a move that could blunt a key U.S. undersea advantage in any Taiwan conflict.
Quieting technology lowers a submarine’s acoustic signature, and Russian help could address a long-standing Chinese weakness in propulsion and stealth, making PLA Navy boats harder for the U.S. to detect and track.
Adm. Samuel Paparo had already warned in 2024 and again in 2025 that Moscow was likely giving Beijing submarine assistance as part of a broader exchange for China’s support to Russia’s war effort.
Paparo told senators China supplied 70% of the machine tools and 90% of the legacy chips helping Russia rebuild its defense industry, while Montgomery said Beijing also backed Moscow through trade, investment and missile components.
China’s embassy did not directly address the alleged transfer, saying military cooperation with Russia is non-confrontational, while the reported exchange underscores how the Ukraine war is tightening Russia-China military links with implications for Taiwan.
