**Lessons from the Iran conflict suggest China’s ageing DF-15B short-range missiles may be far more effective against modern missile defenses than previously assumed.** Military analysts point to Iranian short-range missiles equipped with biconic maneuvering re-entry vehicles (MRVs) that repeatedly penetrated US Patriot and THAAD systems in the Middle East. These MRVs, including the Thunder-500 and Fattah-1, have demonstrated an ability to challenge even advanced interceptors, with one incident in March seeing six Patriot interceptors fail to stop two Iranian Fateh-110 missiles striking oil facilities in Fujairah.</p><p class="summary-lead">**The DF-15B, which debuted in 1999, shares key design features with these Iranian weapons, including a biconic MRV with aerodynamic rudders and terminal maneuverability.** According to analysts, the DF-15B’s Mach 5 penetration speed and ability to make slight directional changes after warhead separation force defense systems to constantly recalculate intercept points, often leading to errors. This makes the missile a low-cost, technologically mature option that can complicate even the most sophisticated ballistic missile defense networks.</p><p class="summary-lead">**For the PLA Rocket Force, the Iran war validates the strategic value of retaining older systems like the DF-15B as a cost-effective supplement to newer hypersonic weapons.** Deployed along China’s coast, these missiles could effectively cover targets in Taiwan, the Ryukyu Islands, and Luzon, with warhead options including anti-radiation, electromagnetic pulse, and earth-penetrating capabilities. Beijing has not signaled retirement of the DF-15B, which participated in exercises around Taiwan as recently as August 2022, underscoring its continued relevance in China’s regional deterrence posture.</p><p class="summary-lead">**What to watch next:** Whether China accelerates upgrades to the DF-15B’s guidance and warhead systems, and how the US and its allies adjust their missile defense deployments in the Indo-Pacific in response to this demonstrated vulnerability.
Key Takeaways
- Iran’s use of biconic MRVs has shown that older short-range missiles can still penetrate advanced US missile defenses like Patriot and THAAD.
- China’s DF-15B shares critical design features with these Iranian missiles, making it a potent low-cost option against modern defenses.
- The DF-15B’s terminal maneuverability forces defense systems into costly recalculations, increasing the likelihood of interception failure.
- Beijing is likely to retain and potentially upgrade the DF-15B as a reliable, mature weapon for regional contingencies, especially around Taiwan.
Insights & Analysis
- The Iran conflict may accelerate a global shift toward investing in maneuverable short-range ballistic missiles as a cost-effective counter to expensive missile defense systems.
- This development could force the US to rethink its layered defense strategy in the Indo-Pacific, potentially prioritizing electronic warfare or directed-energy solutions over kinetic interceptors.
