Did the Iran war just prove that China’s ageing DF-15Bs are still big guns?

Military analysts suggest that China's older Dongfeng-15B short-range missiles might be more effective at penetrating modern missile defenses than previously believed, based on lessons from recent conflicts. An article in Ordnance Science and Technology, attributed to Ma Lihua, posits that missiles equipped with biconic maneuvering re-entry vehicles (MRVs) can achieve a penetration effect comparable to hypersonic projectiles. This idea emerged this month, referencing Iranian claims that its short-range missiles with biconic MRVs successfully penetrated US missile defense systems around bases in the UAE, Kuwait, and Bahrain. The article implies these capabilities could make the DF-15B a valuable asset in overcoming advanced defenses.
