PLA Scientists Warn of Vulnerability in Submarine Cables Critical for Global Data

PLA scientists from the National Defence University have indicated that submarine cables, which carry 99% of global data traffic and support US$10 trillion in daily transactions, are increasingly vulnerable to attacks from unmanned undersea vehicles (UUVs). They attribute this growing threat to the lowering barrier for undersea warfare, particularly influenced by the Aukus pact involving Australia, Britain, and the United States. Historically, underwater operations required expensive crewed submarines, limiting engagement to larger nations. However, the advent of low-cost UUVs allows smaller nations to conduct military activities without risking personnel. This shift could lead to significant geopolitical implications, as control over these cables is crucial for international communications and financial transactions.

Key Points: • Submarine cables carry 99% of global data traffic and are vital for financial transactions. • PLA scientists warn that unmanned undersea vehicles pose a new threat to these cables. • The Aukus pact is cited as a catalyst for increased undersea warfare capabilities.
