Iran is finalizing an agreement with China to acquire CM-302 supersonic anti-ship cruise missiles, according to six people with knowledge of the negotiations, as the United States positions two aircraft carrier strike groups near Iranian waters and President Trump's deadline for a nuclear accord approaches. The weapon system—the export variant of China's YJ-12 missile—features a low-altitude flight profile and approximately 290-kilometer range designed specifically to evade advanced naval defenses.
The deal represents a calculated asymmetric response to overwhelming American conventional superiority in the Gulf. Danny Citrinowicz, a researcher at Israel's Institute for National Security Studies (INSS), characterized the acquisition as a "complete gamechanger" that is "very difficult to intercept," underscoring the system's potential to threaten high-value US naval platforms including aircraft carriers.
Latest situation update
Negotiations accelerated significantly following the 12-day Iran-Israel conflict in June 2025, which depleted Iranian missile inventories and exposed vulnerabilities in Tehran's deterrence architecture. Iranian Deputy Defense Minister Massoud Oraei conducted a previously unreported visit to China to advance the procurement, signaling the priority Tehran assigns to rebuilding its maritime strike capabilities.
The timing intersects directly with heightened US military preparations. The USS Gerald R. Ford and USS Abraham Lincoln carrier strike groups are currently positioned in the Arabian Sea and Gulf of Oman, representing the largest American naval concentration in the region in over a year. This deployment coincides with Trump's ultimatum on Iran's nuclear program and a 48-hour deadline for Iranian proposals ahead of diplomatic talks.

The convergence of Iran's anti-ship missile acquisition with the largest US naval deployment to the region in months creates a volatile dynamic as diplomatic efforts continue. The weapons transfer demonstrates Beijing's willingness to materially support Tehran despite international sanctions, while Iran's focus on maritime strike capabilities reflects a doctrine centered on raising costs for American military intervention. Both developments unfold against the backdrop of an approaching nuclear deadline that has thus far produced limited diplomatic progress.
