Recent analysis of the Iran war indicates China’s DF-15B short-range ballistic missiles may pose a significant threat to modern missile defense systems. A report in *Ordnance Science and Technology* suggests these older missiles, equipped with biconic manoeuvring re-entry vehicles (MRVs), could effectively penetrate defenses. The study, authored by Ma Lihua, posits that their maneuverability allows them to achieve a penetration effect comparable to hypersonic weapons. This challenges previous assessments of the DF-15B’s capabilities, suggesting it remains a potent weapon despite its age. Military analysts are now re-evaluating the missile’s effectiveness in modern warfare scenarios. The findings highlight the potential for relatively simple missile technology to overcome sophisticated defense systems through advanced maneuvering.
