The Evolving Threat Landscape

The primary concern regarding Guam’s vulnerability stems from the People’s Republic of China’s (PRC) rapidly advancing military capabilities and its increasingly assertive foreign policy. Beijing views the U.S. military presence in the region, particularly on Guam, as a direct challenge to its regional ambitions and a constraint on its ability to achieve its objectives.

China’s Anti-Access/Area Denial (A2/AD) Capabilities

• Missile Modernization and Expansion: China has invested heavily in its missile programs, developing a formidable array of ballistic and cruise missiles designed to target U.S. forces and facilities in the first and second island chains. This includes medium-range ballistic missiles (MRBMs) like the DF-26, which is explicitly referred to as a “Guam Killer” by some analysts, capable of striking the island with conventional or potentially nuclear warheads. Long-range cruise missiles also pose a significant threat to airfields and naval vessels.
• Naval Expansion and Modernization: The People’s Liberation Army Navy (PLAN) has undergone a dramatic transformation, rapidly expanding its fleet of modern destroyers, frigates, aircraft carriers, and submarines. This growing naval power allows China to project its influence further into the Pacific and to potentially challenge U.S. naval dominance in the Western Pacific.
• Air Force Modernization: The People’s Liberation Army Air Force (PLAAF) has also modernized significantly, fielding advanced fighter jets, bombers, and transport aircraft. This enhanced air power can be used for power projection, air defense, and offensive operations against targets in the region, including Guam.
• Cyber Warfare and Electronic Warfare: China possesses sophisticated cyber warfare capabilities that could be used to disrupt U.S. communications, C4ISR systems, and critical infrastructure on Guam. Electronic warfare capabilities could be employed to jam radar and communications, further degrading U.S. military effectiveness.
