The Dongfeng-27 (DF-27) is China’s newly developed hypersonic medium-to-intermediate-range ballistic missile, reportedly capable of striking key targets within the Second Island Chain, including Guam. With an estimated range of 5,000 to 8,000 kilometers, it employs a hypersonic glide vehicle (HGV) that maneuvers at speeds exceeding Mach 5 along the edge of the atmosphere, significantly enhancing its ability to penetrate missile defenses. Unlike traditional ballistic missiles, the DF-27’s flight path is far less predictable and can effectively evade existing U.S. missile defense systems in the Asia-Pacific region, such as THAAD and SM-3 interceptors.The U.S. military is particularly concerned because the DF-27 directly threatens Andersen Air Force Base on Guam—a strategic linchpin of America’s Indo-Pacific strategy that hosts B-52 and B-2 bombers, along with critical command and logistics infrastructure. If the DF-27 achieves reliable operational capability, it would drastically shorten the U.S. military’s response time in a potential conflict and undermine its forward-deployed advantage. Moreover, the rapid strike capability of hypersonic weapons challenges the U.S. global rapid-response framework.In summary, the DF-27 not only marks a major leap in China’s missile technology but also reshapes the strategic balance in the Western Pacific, compelling the U.S. military to reassess its defense posture and operational concepts.
东风-27（DF-27）是中国最新研发的高超音速中远程弹道导弹，据信具备打击关岛等第二岛链关键目标的能力。其最大射程估计在5000至8000公里之间，采用高超音速滑翔飞行器（HGV）技术，可在大气层边缘以超过5马赫的速度机动飞行，极大提升了突防能力。与传统弹道导弹相比，DF-27的飞行轨迹更难预测，且能有效规避现有反导系统，如美国部署在亚太地区的“萨德”和“标准-3”拦截系统。美军之所以对东风-27高度紧张，主要因其直接威胁到美军在西太平洋的战略支点——关岛基地。该基地是美军印太战略的核心枢纽，部署有B-52、B-2轰炸机及大量后勤与指挥设施。一旦DF-27形成可靠战力，将显著压缩美军在冲突初期的反应窗口，并削弱其前沿部署优势。此外，高超音速武器的快速打击能力也对美军全球快速反应体系构成挑战。总体而言，东风-27不仅代表中国导弹技术的重大突破，更重塑了西太平洋地区的战略平衡，迫使美军重新评估其防御体系与作战构想。
